p-0031<figref idrefs="DRAWINGS">FIG. 1</figref> is a block diagram of a mobile terminal 100 in accordance with an embodiment of the present invention. <figref idrefs="DRAWINGS">FIG. 1</figref> shows the mobile terminal 100 according to one embodiment of the present invention includes a wireless communication unit 110, an A/V (audio/video) input unit 120, a user input unit 130, a sensing unit 140, an output unit 150, a memory 160, an interface unit 170, a controller 180, a power supply unit 190 and the like. <figref idrefs="DRAWINGS">FIG. 1</figref> shows the mobile terminal 100 having various components, but it is understood that implementing all of the illustrated components is not a requirement. Greater or fewer components may alternatively be implemented.

p-0032In the following description, the above elements of the mobile terminal 100 are explained in sequence.

p-0033First of all, the wireless communication unit 110 typically includes one or more components which permits wireless communication between the mobile terminal 100 and a wireless communication system or network within which the mobile terminal 100 is located. For instance, the wireless communication unit 110 can include a broadcast receiving module 111, a mobile communication module 112, a wireless Internet module 113, a short-range communication module 114, a position-location module 115 and the like.

p-0034The broadcast receiving module 111 receives a broadcast signal and/or broadcast associated information from an external broadcast managing server via a broadcast channel.

p-0035The broadcast channel may include a satellite channel and a terrestrial channel.

p-0036The broadcast managing server generally refers to a server which generates and transmits a broadcast signal and/or broadcast associated information or a server which is provided with a previously generated broadcast signal and/or broadcast associated information and then transmits the provided signal or information to a terminal. The broadcast signal may be implemented as a TV broadcast signal, a radio broadcast signal, and a data broadcast signal, among others. If desired, the broadcast signal may further include a broadcast signal combined with a TV or radio broadcast signal.

p-0037The broadcast associated information includes information associated with a broadcast channel, a broadcast program, a broadcast service provider, etc. And, the broadcast associated information can be provided via a mobile communication network. In this case, the broadcast associated information can be received by the mobile communication module 112.

p-0038The broadcast associated information can be implemented in various forms. For instance, broadcast associated information may include an electronic program guide (EPG) of digital multimedia broadcasting (DMB) and electronic service guide (ESG) of digital video broadcast-handheld (DVB-H).

p-0039The broadcast receiving module 111 may be configured to receive broadcast signals transmitted from various types of broadcast systems. By nonlimiting example, such broadcasting systems include digital multimedia broadcasting-terrestrial (DMB-T), digital multimedia broadcasting-satellite (DMB-S), digital video broadcast-handheld (DVB-H), the data broadcasting system known as media forward link only (MediaFLO®) and integrated services digital broadcast-terrestrial (ISDB-T). Optionally, the broadcast receiving module 111 can be configured suitable for other broadcasting systems as well as the above-explained digital broadcasting systems.

p-0040The broadcast signal and/or broadcast associated information received by the broadcast receiving module 111 may be stored in a suitable device, such as a memory 160.

p-0041The mobile communication module 112 transmits/receives wireless signals to/from one or more network entities (e.g., base station, external terminal, server, etc.). Such wireless signals may represent audio, video, and data according to text/multimedia message transceivings, among others.

p-0042The wireless internet module 113 supports Internet access for the mobile terminal 100. This module may be internally or externally coupled to the mobile terminal 100. In this case, the wireless Internet technology can include WLAN (Wireless LAN) (Wi-Fi), Wibro (Wireless broadband), Wimax (World Interoperability for Microwave Access), HSDPA (High Speed Downlink Packet Access), etc.

p-0043The short-range communication module 114 facilitates relatively short-range communications. Suitable technologies for implementing this module include radio frequency identification (RFID), infrared data association (IrDA), ultra-wideband (UWB), as well at the networking technologies commonly referred to as Bluetooth and ZigBee, to name a few.

p-0044The position-location module 115 identifies or otherwise obtains the location of the mobile terminal 100. If desired, this module may be implemented with a global positioning system (GPS) module.

p-0045Referring to <figref idrefs="DRAWINGS">FIG. 1</figref>, the audio/video (NV) input unit 120 is configured to provide audio or video signal input to the mobile terminal 100. As shown, the A/V input unit 120 includes a camera 121 and a microphone 122. The camera 121 receives and processes image frames of still pictures or video, which are obtained by an image sensor in a video call mode or a photographing mode. And, the processed image frames can be displayed on the display 151.

p-0046The image frames processed by the camera 121 can be stored in the memory 160 or can be externally transmitted via the wireless communication unit 110. Optionally, at least two cameras 121 can be provided to the mobile terminal 100 according to environment of usage.

p-0047The microphone 122 receives an external audio signal while the portable device is in a particular mode, such as phone call mode, recording mode and voice recognition. This audio signal is processed and converted into electric audio data. The processed audio data is transformed into a format transmittable to a mobile communication base station via the mobile communication module 112 in case of a call mode. The microphone 122 typically includes assorted noise removing algorithms to remove noise generated in the course of receiving the external audio signal.

p-0048The user input unit 130 generates input data responsive to user manipulation of an associated input device or devices. Examples of such devices include a keypad, a dome switch, a touchpad (e.g., static pressure/capacitance), a jog wheel, a jog switch, etc.

p-0049The sensing unit 140 provides sensing signals for controlling operations of the mobile terminal 100 using status measurements of various aspects of the mobile terminal. For instance, the sensing unit 140 may detect an open/close status of the mobile terminal 100, relative positioning of components (e.g., a display and keypad) of the mobile terminal 100, a change of position of the mobile terminal 100 or a component of the mobile terminal 100, a presence or absence of user contact with the mobile terminal 100, orientation or acceleration/deceleration of the mobile terminal 100.

p-0050As an example, consider the mobile terminal 100 being configured as a slide-type mobile terminal. In this configuration, the sensing unit 140 may sense whether a sliding portion of the mobile terminal is open or closed. Other examples include the sensing unit 140 sensing the presence or absence of power provided by the power supply 190, the presence or absence of a coupling or other connection between the interface unit 170 and an external device. And, the sensing unit 140 can include a proximity sensor 141.

p-0051The output unit 150 generates outputs relevant to the senses of sight, hearing, touch and the like. And, the output unit 150 includes the display 151, an audio output module 152, an alarm unit 153, a haptic module 154, a projector module 155 and the like.

p-0052The display 151 is typically implemented to visually display (output) information associated with the mobile terminal 100. For instance, if the mobile terminal is operating in a phone call mode, the display will generally provide a user interface (UI) or graphical user interface (GUI) which includes information associated with placing, conducting, and terminating a phone call. As another example, if the mobile terminal 100 is in a video call mode or a photographing mode, the display 151 may additionally or alternatively display images which are associated with these modes, the UI or the GUI.

p-0053The display module 151 may be implemented using known display technologies including, for example, a liquid crystal display (LCD), a thin film transistor-liquid crystal display (TFT-LCD), an organic light-emitting diode display (OLED), a flexible display and a three-dimensional display. The mobile terminal 100 may include one or more of such displays.

p-0054Some of the above displays can be implemented in a transparent or optical transmissive type, which can be named a transparent display. As a representative example for the transparent display, there is TOLED (transparent OLED) or the like. A rear configuration of the display 151 can be implemented in the optical transmissive type as well. In this configuration, a user is able to see an object in rear of a terminal body via the area occupied by the display 151 of the terminal body.

p-0055At least two displays 151 can be provided to the mobile terminal 100 in accordance with the implemented configuration of the mobile terminal 100. For instance, a plurality of displays can be arranged on a single face of the mobile terminal 100 in a manner of being spaced apart from each other or being built in one body. Alternatively, a plurality of displays can be arranged on different faces of the mobile terminal 100.

p-0056In case that the display 151 and a sensor for detecting a touch action (hereinafter called ‘touch sensor’) configures a mutual layer structure (hereinafter called ‘touchscreen’), it is able to use the display 151 as an input device as well as an output device. In this case, the touch sensor can be configured as a touch film, a touch sheet, a touchpad or the like.

p-0057The touch sensor can be configured to convert a pressure applied to a specific portion of the display 151 or a variation of a capacitance generated from a specific portion of the display 151 to an electric input signal. Moreover, it is able to configure the touch sensor to detect a pressure of a touch as well as a touched position or size.

p-0058If a touch input is made to the touch sensor, signal(s) corresponding to the touch is transferred to a touch controller. The touch controller processes the signal(s) and then transfers the processed signal(s) to the controller 180. Therefore, the controller 180 is able to know whether a prescribed portion of the display 151 is touched.

p-0059Referring to <figref idrefs="DRAWINGS">FIG. 1</figref>, a proximity sensor (not shown in the drawing) can be provided to an internal area of the mobile terminal 100 enclosed by the touchscreen or around the touchscreen. The proximity sensor is the sensor that detects a presence or non-presence of an object approaching a prescribed detecting surface or an object existing around the proximity sensor using an electromagnetic field strength or infrared ray without mechanical contact. Hence, the proximity sensor has durability longer than that of a contact type sensor and also has utility wider than that of the contact type sensor.

p-0060The proximity sensor can include one of a transmissive photoelectric sensor, a direct reflective photoelectric sensor, a mirror reflective photoelectric sensor, a radio frequency oscillation proximity sensor, an electrostatic capacity proximity sensor, a magnetic proximity sensor, an infrared proximity sensor and the like. In case that the touchscreen includes the electrostatic capacity proximity sensor, it is configured to detect the proximity of a pointer using a variation of electric field according to the proximity of the pointer. In this case, the touchscreen (touch sensor) can be classified as the proximity sensor.

p-0061In the following description, for clarity, an action that a pointer approaches without contacting with the touchscreen to be recognized as located on the touchscreen is named ‘proximity touch’. And, an action that a pointer actually touches the touchscreen is named ‘contact touch’. The meaning of the position on the touchscreen proximity-touched by the pointer means the position of the pointer which vertically opposes the touchscreen when the pointer performs the proximity touch.

p-0062The proximity sensor detects a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch duration, a proximity touch position, a proximity touch shift state, etc.). And, information corresponding to the detected proximity touch action and the detected proximity touch pattern can be outputted to the touchscreen.

p-0063The audio output module 152 functions in various modes including a call-receiving mode, a call-placing mode, a recording mode, a voice recognition mode, a broadcast reception mode and the like to output audio data which is received from the wireless communication unit 110 or is stored in the memory 160. During operation, the audio output module 152 outputs audio relating to a particular function (e.g., call received, message received, etc.). The audio output module 152 is often implemented using one or more speakers, buzzers, other audio producing devices, and combinations thereof.

p-0064The alarm unit 153 is output a signal for announcing the occurrence of a particular event associated with the mobile terminal 100. Typical events include a call received event, a message received event and a touch input received event. The alarm unit 153 is able to output a signal for announcing the event occurrence by way of vibration as well as video or audio signal. The video or audio signal can be outputted via the display 151 or the audio output unit 152. Hence, the display 151 or the audio output module 152 can be regarded as a part of the alarm unit 153.

p-0065The haptic module 154 generates various tactile effects that can be sensed by a user. Vibration is a representative one of the tactile effects generated by the haptic module 154. Strength and pattern of the vibration generated by the haptic module 154 are controllable. For instance, different vibrations can be outputted in a manner of being synthesized together or can be outputted in sequence.

p-0066The haptic module 154 is able to generate various tactile effects as well as the vibration. For instance, the haptic module 154 generates the effect attributed to the arrangement of pins vertically moving against a contact skin surface, the effect attributed to the injection/suction power of air though an injection/suction hole, the effect attributed to the skim over a skin surface, the effect attributed to the contact with electrode, the effect attributed to the electrostatic force, the effect attributed to the representation of hold/cold sense using an endothermic or exothermic device and the like.

p-0067The haptic module 154 can be implemented to enable a user to sense the tactile effect through a muscle sense of finger, arm or the like as well as to transfer the tactile effect through a direct contact. Optionally, at least two haptic modules 154 can be provided to the mobile terminal 100 in accordance with the corresponding configuration type of the mobile terminal 100.

p-0068The projector module 155 is the element for performing an image projector function using the mobile terminal 100. And, the projector module 155 is able to display an image, which is identical to or partially different at least from the image displayed on the display 151, on an external screen or wall according to a control signal of the controller 180.

p-0069In particular, the projector module 155 can include a light source (not shown in the drawing) generating light (e.g., laser) for projecting an image externally, an image producing means (not shown in the drawing) for producing an image to output externally using the light generated from the light source, and a lens (not shown in the drawing) for enlarging to output the image externally in a predetermined focus distance. And, the projector module 155 can further include a device (not shown in the drawing) for adjusting an image projected direction by mechanically moving the lens or the whole module.

p-0070The projector module 155 can be classified into a CRT (cathode ray tube) module, an LCD (liquid crystal display) module, a DLP (digital light processing) module or the like according to a device type of a display means. In particular, the DLP module is operated by the mechanism of enabling the light generated from the light source to reflect on a DMD (digital micro-mirror device) chip and can be advantageous for the downsizing of the projector module 151.

p-0071Preferably, the projector module 155 can be provided in a length direction of a lateral, front or backside direction of the mobile terminal 100. And, it is understood that the projector module 155 can be provided to any portion of the mobile terminal 100 according to the necessity thereof.

p-0072The memory unit 160 is generally used to store various types of data to support the processing, control, and storage requirements of the mobile terminal 100. Examples of such data include program instructions for applications operating on the mobile terminal 100, contact data, phonebook data, messages, audio, still pictures, moving pictures, etc. And, a recent use history or a cumulative use frequency of each data (e.g., use frequency for each phonebook, each message or each multimedia) can be stored in the memory unit 160. Moreover, data for various patterns of vibration and/or sound outputted in case of a touch input to the touchscreen can be stored in the memory unit 160.

p-0073The memory 160 may be implemented using any type or combination of suitable volatile and non-volatile memory or storage devices including hard disk, random access memory (RAM), static random access memory (SRAM), electrically erasable programmable read-only memory (EEPROM), erasable programmable read-only memory (EPROM), programmable read-only memory (PROM), read-only memory (ROM), magnetic memory, flash memory, magnetic or optical disk, multimedia card micro type memory, card-type memory (e.g., SD memory, XD memory, etc.), or other similar memory or data storage device. And, the mobile terminal 100 is able to operate in association with a web storage for performing a storage function of the memory 160 on Internet.

p-0074The interface unit 170 is often implemented to couple the mobile terminal 100 with external devices. The interface unit 170 receives data from the external devices or is supplied with the power and then transfers the data or power to the respective elements of the mobile terminal 100 or enables data within the mobile terminal 100 to be transferred to the external devices. The interface unit 170 may be configured using a wired/wireless headset port, an external charger port, a wired/wireless data port, a memory card port, a port for coupling to a device having an identity module, audio input/output ports, video input/output ports, an earphone port and/or the like.

p-0075The identity module is the chip for storing various kinds of information for authenticating a use authority of the mobile terminal 100 and can include User Identify Module (UIM), Subscriber Identify Module (SIM), Universal Subscriber Identity Module (USIM) and/or the like. A device having the identity module (hereinafter called ‘identity device’) can be manufactured as a smart card. Therefore, the identity device is connectible to the mobile terminal 100 via the corresponding port.

p-0076When the mobile terminal 110 is connected to an external cradle, the interface unit 170 becomes a passage for supplying the mobile terminal 100 with a power from the cradle or a passage for delivering various command signals inputted from the cradle by a user to the mobile terminal 100. Each of the various command signals inputted from the cradle or the power can operate as a signal enabling the mobile terminal 100 to recognize that it is correctly loaded in the cradle.

p-0077The controller 180 typically controls the overall operations of the mobile terminal 100. For example, the controller 180 performs the control and processing associated with voice calls, data communications, video calls, etc. The controller 180 may include a multimedia module 181 that provides multimedia playback. The multimedia module 181 may be configured as part of the controller 180, or implemented as a separate component.

p-0078Moreover, the controller 180 is able to perform a pattern recognizing process for recognizing a writing input and a picture drawing input carried out on the touchscreen as characters or images, respectively.

p-0079The power supply unit 190 provides power required by the various components for the mobile terminal 100. The power may be internal power, external power, or combinations thereof.

p-0080Various embodiments described herein may be implemented in a computer-readable medium using, for example, computer software, hardware, or some combination thereof. For a hardware implementation, the embodiments described herein may be implemented within one or more application specific integrated circuits (ASICs), digital signal processors (DSPs), digital signal processing devices (DSPDs), programmable logic devices (PLDs), field programmable gate arrays (FPGAs), processors, controllers, micro-controllers, microprocessors, other electronic units designed to perform the functions described herein, or a selective combination thereof.

p-0083The mobile terminal 100 shown in the drawing has a bar type terminal body. Yet, the mobile terminal 100 may be implemented in a variety of different configurations. Examples of such configurations include folder-type, slide-type, rotational-type, swing-type and combinations thereof. For clarity, further disclosure will primarily relate to a bar-type mobile terminal 100. However such teachings apply equally to other types of mobile terminals.

p-0084Referring to <figref idrefs="DRAWINGS">FIG. 2</figref>, the mobile terminal 100 includes a case (casing, housing, cover, etc.) configuring an exterior thereof. In the present embodiment, the case can be divided into a front case 101 and a rear case 102. Various electric/electronic parts are loaded in a space provided between the front and rear cases 101 and 102. Optionally, at least one middle case can be further provided between the front and rear cases 101 and 102 in addition.

p-0087The display 151 occupies most of a main face of the front case 101. The audio output unit 151 and the camera 121 are provided to an area adjacent to one of both end portions of the display 151, while the user input unit 131 and the microphone 122 are provided to another area adjacent to the other end portion of the display 151. The user input unit 132 and the interface 170 can be provided to lateral sides of the front and rear cases 101 and 102.

p-0088The input unit 130 is manipulated to receive a command for controlling an operation of the terminal 100. And, the input unit 130 is able to include a plurality of manipulating units 131 and 132. The manipulating units 131 and 132 can be named a manipulating portion and may adopt any mechanism of a tactile manner that enables a user to perform a manipulation action by experiencing a tactile feeling.

p-0089Content inputted by the first or second manipulating unit 131 or 132 can be diversely set. For instance, such a command as start, end, scroll and the like is inputted to the first manipulating unit 131. And, a command for a volume adjustment of sound outputted from the audio output unit 152, a command for a switching to a touch recognizing mode of the display 151 or the like can be inputted to the second manipulating unit 132.

p-0090Interconnected operational mechanism between the display 151 and the touchpad 135 are explained with reference to <figref idrefs="DRAWINGS">FIG. 3</figref> as follows.

p-0091<figref idrefs="DRAWINGS">FIG. 3</figref> is a front-view diagram of a terminal according to one embodiment of the present invention for explaining an operational state thereof.

p-0092First of all, various kinds of visual information can be displayed on the display 151. And, theses information can be displayed in characters, numerals, symbols, graphics, icons and the like.

p-0093In order to input the information, at least one of the characters, numerals, symbols, graphics and icons are represented as a single predetermined array to be implemented in a keypad formation. And, this keypad formation can be so-called ‘soft keys’.

p-0094<figref idrefs="DRAWINGS">FIG. 3</figref> shows that a touch applied to a soft key is inputted through a front face of a terminal body.

p-0095The display 151 is operable through an entire area or by being divided into a plurality of regions. In the latter case, a plurality of the regions can be configured interoperable.

p-0096For instance, an output window 151a and an input window 151b are displayed on the display 151. A soft key 151c′ representing a digit for inputting a phone number or the like is outputted to the input window 151b. If the soft key 151c′ is touched, a digit corresponding to the touched soft key is outputted to the output window 151a. If the first manipulating unit 131 is manipulated, a call connection for the phone number displayed on the output window 151a is attempted.

p-0097Besides, the display 151 or the touchpad 135 can be configured to receive a touch input by scroll. A user scrolls the display 151 or the touchpad 135 to shift a cursor or pointer located at an entity (e.g., icon or the like) displayed on the display 151. Furthermore, in case that a finger is shifted on the display 151 or the touchpad 135, a path of the shifted finger can be visually displayed on the display 151. This may be useful in editing an image displayed on the display 151.

p-0098To cope with a case that both of the display (touch screen) 151 and the touchpad 135 are touched together within a predetermined time range, one function of the terminal can be executed. The above case of the simultaneous touch may correspond to a case that the terminal body is held by a user using a thumb and a first finger (clamping). The above function can include activation or deactivation for the display 151 or the touchpad 135.

p-0099Meanwhile, such a graphic for pointing at a specific object on a display unit or selecting a menu from the display unit as an arrow, a finger and the like is called a pointer or a cursor. Yet, the pointer is frequently used to mean a finger, a stylus pen or the like for a touch manipulation and the like. In order to clearly discriminate the pointer and the cursor from each other in this disclosure, a graphic displayed on a display unit is named a cursor and such a physical means for performing a touch, a proximity touch, a gesture and the like as a finger, a stylus pen and the like is named a pointer.

p-0100In the following description, a method of displaying a 3D image in a mobile terminal applicable to embodiments of the present invention and a display unit configuration for the same are explained.

p-0101First of all, 3D images implemented on the display unit 151 of the mobile terminal 100 according to can be mainly classified into two kinds of categories. In this case, the reference for this classification is attributed to whether different images are provided to both eyes, respectively.

p-0102The first 3D image category is described as follows.

p-0103First of all, the first category is a monoscopic scheme of providing the same image to both eyes and is advantageous in that it can be implemented with a general display unit 151. In particular, the controller 180 arranges a polyhedron generated from combining at least one of dots, lines, surfaces or combination thereof in a virtual 3D space and enables an image, which is generated from seeing the polyhedron in a specific view, to be displayed on the display unit 151. Therefore, such a stereoscopic image can substantially include a planar image.

p-0104Secondly, the second category is a stereoscopic scheme of providing different image to both eyes, respectively, which uses the principle that a user can sense a stereoscopic effect in looking at an object with human eyes. In particular, human eyes are configured to see different planar images in looking at the same object due to a distance between both eyes. These different images are forwarded to a human brain via retinas. The human brain is able to sense depth and reality of a 3D image by combining the different images together. Therefore, the binocular disparity attributed to the distance between both of the eyes enables the user to sense the stereoscopic effect despite that there is an individual difference of the binocular disparity more or less. Therefore, the binocular disparity becomes the most important factor of the second category. The binocular disparity is explained in detail with reference to <figref idrefs="DRAWINGS">FIG. 4</figref> as follows.

p-0105<figref idrefs="DRAWINGS">FIG. 4</figref> is a diagram for explaining the principle of binocular disparity.

p-0106Referring to <figref idrefs="DRAWINGS">FIG. 4</figref>, assume a situation that a hexahedron 410 is positioned as a subject in front below an eye's height to be seen through human eyes. In this case, a left eye is able to see a left eye planar image 420 revealing three facets including a top side, a front side and a left lateral side of the hexahedron 410 only. And, a right eye is able to see a right eye planar image 430 revealing three facets including the top side, the front side and a right lateral side of the hexahedron 410 only.

p-0107Even if a real thing is not actually positioned in front of both eyes of a user, if the left eye planar image 420 and the right eye planar image 430 are set to arrive at the left eye and the right eye, respectively, a user is able to substantially sense the hexahedron 410 as if looking at the hexahedron 31 actually.

p-0108Thus, in order to implement the 3D image belonging to the second category in the mobile terminal 100, images of the same object should arrive at both eyes in a manner of being discriminated from each other for the left and right eye images of the same object with a predetermined parallax.

p-0109In order to discriminate the above-mentioned two categories from each other in this disclosure, a stereoscopic image belonging to the first category shall be named ‘monoscopic 3D image’ and a stereoscopic image belonging to the second category shall be named ‘3D stereoscopic image’.

p-0110A method of implementing a 3D stereoscopic image is described as follows.

p-0111First of all, as mentioned in the following description, in order to implement a 3D stereoscopic image, an image for a right eye and an image for a left eye need to arrive at both eyes in a manner of being discriminated from each other. For this, various methods are explained as follows.

p-01121) Parallax Barrier Scheme

p-0113The parallax barrier scheme enables different images arrive at both eyes in a manner of controlling a propagating direction of light by electronically driving a cutoff device provided between a general display and both eyes.

p-0114A structure of a parallax barrier type display unit 151 for displaying a 3D image can be configured in a manner that a general display device is combined with a switch LC (liquid crystals). A propagating direction of light is controlled by activating an optical parallax barrier provided to the switch LC, whereby the light is separated into two different lights to arrive at left and right eyes, respectively. Thus, when an image generated from combining an image for the right eye and an image for the left eye together is displayed on the display device, a user sees the images corresponding to the eyes, respectively, thereby feeling the 3D or stereoscopic effect.

p-0115Alternatively, the parallax barrier is electrically controlled to enable entire light to be transmitted therethrough, whereby the light separation due to the parallax barrier is avoided. Therefore, the same image can be seen through left and right eyes. In this case, the same function of a conventional display unit is available.

p-0116Meanwhile, the parallax barrier provides a 3D stereoscopic image with reference to one axis. Yet, the present invention is able to use a parallax barrier that enables parallel translation in at least two axial directions according to a control signal from the controller 180.

p-01172) Lenticular

p-0118The lenticular scheme relates to a method of using a lenticular screen provided between a display and both eyes. In particular, a propagating direction of light is refracted via lens on the lenticular screen, whereby different images arrive at both eyes, respectively.

p-01193) Polarized Glasses

p-0120According to the polarized glasses scheme, polarizing directions are set orthogonal to each other to provide different images to both eyes, respectively. In case of circular polarization, polarization is performed to have different rotational direction, whereby different images can be provided to both eyes, respectively.

p-01214) Active Shutter

p-0122This scheme is a sort of the glasses scheme. In particular, a right eye image and a left eye image are alternately displayed on a display unit with prescribed periodicity. And, user's glasses close its shutter in an opposite direction when an image of a corresponding direction is displayed. Therefore, the image of the corresponding direction can arrive at the eyeball in the corresponding direction. Namely, while the left eye image is being displayed, a shutter of the right eye is closed to enable the left eye image to arrive at the left eye only. On the contrary, while the right eye image is being displayed, a shutter of the left eye is closed to enable the right eye image to arrive at the right eye only.

p-0123For clarity of description, a mobile terminal mentioned in the following description is assumed as including at least one of the components shown in <figref idrefs="DRAWINGS">FIG. 1</figref>. In particular, a mobile terminal according to the present invention includes a display unit capable of displaying a 3D user interface including a 3D object by at least one method among the above-mentioned monoscopic 3D image and 3D stereoscopic image implementing schemes. In this case, the 3D object means a polyhedron generated from combining at least one of dots, lines, surfaces or combination thereof in a manner of having a prescribed 3D depth in a virtual stereoscopic space. And, the 3D user interface means a graphic user interface (GUI) including at least one 3D object. Therefore, in case that a 3D user interface is implemented into a monoscopic 3D image, it means that a user is provided with a planar image generated from seeing the 3D user interface including a 3D object in a specific view. In case that a 3D user interface is implemented into a 3D stereoscopic image, it means that left and right eye images generated from seeing the 3D user interface in a specific view are provided to arrive at corresponding eyes of a user, respectively.

p-0124Display State Change of 3D User Interface

p-0125A mobile terminal and controlling method thereof according to one embodiment of the present invention are provided. In particular, according to one embodiment of the present invention, when a 3D user interface including at least one 3D object in a virtual stereoscopic space is displayed on a display unit, if at least one partial region of the 3D user interface is selected, a display state of the selected region can be changed according to a user input.

p-0126<figref idrefs="DRAWINGS">FIG. 5</figref> is a flowchart for one example of a method of controlling a 3D user interface implemented in a mobile terminal according to one embodiment of the present invention.

p-0127Referring to <figref idrefs="DRAWINGS">FIG. 5</figref>, a 3D user interface can be activated on the display unit 151 by means of a prescribed command input through the user input unit 130 or an application executed as default simultaneously with a power application [S501].

p-0128In this case, the present invention is non-limited by a type and form of a 3D user interface. For instance, a 3D user interface can correspond to one method for displaying a main menu displayed on a wallpaper in a mobile terminal or can include a user interface provided by an augmented reality application.

p-0129Subsequently, a display state change mode can be executed if a user performs a prescribed menu manipulation through the user input unit [S502]. Alternatively, the display state change mode can be executed as default according to a setting of a corresponding user interface [S502].

p-0130In this case, the display state change mode means a mode that a displayed state of at least one portion of a 3D user interface can be changed to correspond to a user's command input.

p-0131Once the display state change mode is executed, it is able to designate a display state change region corresponding to a region for changing a state on the 3D user interface by means of a user's input [S503].

p-0132In this case, the display state change region becomes at least one partial space of a virtual space displayed on a 3D user interface. In order to designate such a space, if one facet of a polyhedron enclosing the corresponding space is first selected, it is able to use a method of forming a polygonal pillar in prescribed height with a base side set to the selected facet. Alternatively, it is able to use a method for a user to directly designate a height of the polygonal pillar through a prescribed input. A detailed implementation of designating the present region shall be explained later.

p-0133Once the display sate change region is designated, a polyhedron of a prescribed shape including the corresponding region, i.e., a change region polyhedron is generated. And, the generated change region polyhedron can be displayed with a prescribed visual effect [S504].

p-0134In doing so, the change region polyhedron is enlarged or reduced at a prescribed ratio to be greater or smaller than the selected display state change region. The enlarged/reduced change region polyhedron is displayed as an OSD (on screen display) by being overlaid on the 3D user interface or can be displayed on a separate region or window.

p-0135Moreover, the change region polyhedron can be displayed as a 3D stereoscopic image. In this case, the change region polyhedron can be displayed as the 3D stereoscopic image only. Alternatively, a whole display can be displayed as a 3D stereoscopic image as soon as the change region polyhedron is displayed. For this, the controller 180 is able to give a different 3D depth to each of the change region polyhedron and a 3D user interface except the change region polyhedron. Consequently, a user is able to feel the change region polyhedron as if the change region polyhedron is located closer to the user than the rest of the 3D user interface except the change region polyhedron (i.e., as if the change region polyhedron seems to float.

p-0136If the change region polyhedron is displayed, the user is able to input a command for shifting(scrolling)/enlarging/reducing the polyhedron via a prescribed menu manipulation or a touchscreen provided to the mobile terminal [S505].

p-0137If such a command is inputted, a display state of the polyhedron is changed. The changed display state can be then displayed on the display unit [S506].

p-0138One change region polyhedron is selected in the description with reference to <figref idrefs="DRAWINGS">FIG. 5</figref>, by which the present invention is non-limited. For instance, a plurality of change region polyhedrons can be selected. If so, a user is able to change a display state of each of a plurality of the change region polyhedrons by manipulating the corresponding change region polyhedron selectively.

p-0139In the following description, a method of changing a display state of a 3D user interface according to one embodiment of the present invention is explained in detail using a detailed form of the 3D user interface.

p-0140<figref idrefs="DRAWINGS">FIG. 6</figref> is a diagram for one example of a display form of a 3D user interface implemented in a mobile terminal according to one embodiment of the present invention.

p-0141Referring to <figref idrefs="DRAWINGS">FIG. 6</figref>, assume that a 3D user interface is provided via an application for informing a user of perimeter location information. In particular, as a perimeter location information related application is executed on the display unit, a triangular pillar type building 610, a rectangular pillar type building 620 and a user's current position 630 can be displayed on a 2D map [<figref idrefs="DRAWINGS">FIG. 6</figref> (a)]. In this case, as the user changes the 2D map into a 3D form via a prescribed menu manipulation, a 3D map representing each of the buildings as a 3D object can be displayed via a 3D user interface [<figref idrefs="DRAWINGS">FIG. 6</figref> (b)].

p-0142In the following description, a configuration of a display form change region is explained with reference to <figref idrefs="DRAWINGS">FIG. 7</figref>.

p-0143<figref idrefs="DRAWINGS">FIG. 7</figref> is a diagram for one example of a change region polyhedron form displayed if a prescribed region of a 3D user interface displayed on a mobile terminal according to one embodiment of the present invention is designated to a display state change region.

p-0144Referring to <figref idrefs="DRAWINGS">FIG. 7</figref>, assume a case that a display state change region is designated by a prescribed method while such a 3D user interface as shown in <figref idrefs="DRAWINGS">FIG. 6</figref> (b) is displayed.

p-0145First of all, a display form change region 710 can be designated as a cube form including a rectangular pillar type building 620 [<figref idrefs="DRAWINGS">FIG. 7</figref> (a)].

p-0146If the display form change region is designated, a change region polyhedron (e.g., a cube form) can be displayed as shown in <figref idrefs="DRAWINGS">FIG. 7</figref> (b) or <figref idrefs="DRAWINGS">FIG. 7</figref> (c). In particular, referring to <figref idrefs="DRAWINGS">FIG. 7</figref> (b), an image of a front view of a corresponding facet can be displayed on each facet of the change region polyhedron. Referring to <figref idrefs="DRAWINGS">FIG. 7</figref> (c), an image of a prescribed region of the chance region polyhedron seen in the same view of viewing the 3D user interface can be displayed on each facet of the change region polyhedron.

p-0147In the following description, a method of designating a display state change region is explained with reference to <figref idrefs="DRAWINGS">FIG. 8</figref>.

p-0148<figref idrefs="DRAWINGS">FIG. 8</figref> is a diagram for one example of a method of designating a display state change region to a 3D user interface according to one embodiment of the present invention.

p-0149Referring to <figref idrefs="DRAWINGS">FIG. 8</figref>, assume that the display unit 151 includes a touchscreen configured to recognize a user's touch input. Assume that the display state change region is selected in a following manner. First of all, a display state change region is a polygonal pillar type. Secondly, after a polygon becoming a base side of a polygonal pillar has been designated, a height is given to the designated polygon.

p-0150Before a 3D user interface is activated as shown in <figref idrefs="DRAWINGS">FIG. 6</figref> (a), it is able to use a method of selecting a polygon, which starts from a start point 810 and then returns to the start point, by a drag input via a pointer 800 [<figref idrefs="DRAWINGS">FIG. 8</figref> (a)]. In this case, a contour line of the polygon can be displayed along a trace of the drag input on the display unit by having a prescribed visual effect given thereto.

p-0151Once the pointer 800 arrives at the start point 810 of the drag input, a prescribed visual effect 830 can be given to the selected polygon [<figref idrefs="DRAWINGS">FIG. 8</figref> (b)]. In this case, as mentioned in the foregoing assumption, the selected polygon can becomes the base side of the display state change region. In particular, by giving a preset height or a user selected height to a corresponding polygon, a polygonal pillar having its base side set to the corresponding polygon can be designated to the display state change region.

p-0152Meanwhile, if the 3D user interface is already activated, a polygon 830, which becomes a base side of a polygonal pillar corresponding to a display state change region, is first designated and a pointer 800 is then dragged to designate a height of the polygonal pillar [<figref idrefs="DRAWINGS">FIG. 8</figref> (c)].

p-0153Hence, it is able to select such a display state change region 840 as shown in <figref idrefs="DRAWINGS">FIG. 8</figref> (d).

p-0154In the aforesaid display state change region designating method, the step of drawing a polygon using a drag input can be replaced by a step of touching apexes of a polygon of the same shape in turn. In doing so, it is able to change a form and/or size of the polygon in a manner of dragging one of the apexes of the polygon.

p-0155Alternatively, if a specific 3D object is selected, a polyhedron including all corresponding objects can be directly selected as a display state change region. For instance, if the rectangular pillar type building 620 is touched in <figref idrefs="DRAWINGS">FIG. 7</figref> (a), a virtual space corresponding to (or greater by a prescribed ratio than) a specific building in a 3D user interface can be designated to the display state change region.

p-0156In the following description, a process for displaying a selected display state change region as a change region polyhedron is explained with reference to <figref idrefs="DRAWINGS">FIG. 9</figref>.

p-0157<figref idrefs="DRAWINGS">FIG. 9</figref> is a diagram for one example of a form of displaying a change region polyhedron on a 3D user interface in a mobile terminal according to one embodiment of the present invention.

p-0158Referring to <figref idrefs="DRAWINGS">FIG. 9</figref>, if a display state change region 910 is selected from a 3D user interface [<figref idrefs="DRAWINGS">FIG. 9</figref> (a)], a change region polyhedron 920 of a form generated from enlarging the display state change region at a prescribed ratio can be displayed in a manner of being overlaid on the 3D user interface [<figref idrefs="DRAWINGS">FIG. 9</figref> (b)]. In doing so, a 3D depth lower than the previously displayed 3D user interface can be given to the change region polyhedron (i.e.; the change region polyhedron looks as if located closer to a user than the 3D user interface). Moreover, the change region polyhedron 920 can be displayed in a manner of being enlarged lager than the selected display state change region 910.

p-0159Alternatively, the change region polyhedron can be displayed as a separate region or window on the display unit 151 in a manner of having a transparent effect given thereto or avoiding being overlapped with the 3D user interface as well as is displayed by being overlaid on the 3D user interface.

p-0160In the following description, a detailed form of changing a display state of a change region polyhedron by manipulating the displayed change region polyhedron is explained with reference to <figref idrefs="DRAWINGS">FIGS. 10 to 14</figref>.

p-0161In the following drawings including <figref idrefs="DRAWINGS">FIG. 10</figref>, a change region polyhedron, which is generated using a display state change region selected from a random 3D user interface by one of the aforesaid methods, is displayed as a cube (i.e., hexahedron). For clarity of the following description, a different schematic diagram if displayed on each facet of the cube for the purpose of discrimination.

p-0162<figref idrefs="DRAWINGS">FIG. 10</figref> is a diagram for one example of a method of scrolling a change region polyhedron in a mobile terminal according to one embodiment of the present invention.

p-0163Referring to <figref idrefs="DRAWINGS">FIG. 10</figref> (a), a change region polyhedron 1000 of a cube type is displayed. When the change region polyhedron 1000 is displayed, an icon box 1010 for changing a display state of the change region polyhedron can be displayed as default automatically according to a setting. Alternatively, the icon box 1010 can be displayed if a prescribed command is inputted by a user via the user input unit 130.

p-0164In the icon box 1010 for changing the display state, a scroll mode icon 1011, a rotate mode icon, an enlarge/reduce mode icon and the like can be included.

p-0165If the user selects the scroll mode icon 1011, a scroll key button 1020 for right and left scrolls and a scroll key button 1030 for top and bottom scrolls can be displayed in the vicinity of the change region polyhedron.

p-0166If the user manipulates the scroll key button 1025 corresponding to a left direction, referring to <figref idrefs="DRAWINGS">FIG. 10</figref> (b), an image displayed on each facet of the change region polyhedron 1000 can be scrolled. In dong so, an image of the facet vertical to the scroll direction may not be scrollable.

p-0167In the following description, a method of rotating a change region polyhedron is explained with reference to <figref idrefs="DRAWINGS">FIG. 11</figref>.

p-0168<figref idrefs="DRAWINGS">FIG. 11</figref> is a diagram for one example of a method of rotating a change region polyhedron in a mobile terminal according to one embodiment of the present invention.

p-0169Referring to <figref idrefs="DRAWINGS">FIG. 11</figref> (a), assume a case that the rotate mode icon 1013 in the icon box 1010 is selected in the situation similar to that shown in <figref idrefs="DRAWINGS">FIG. 10</figref> (a). Hence, a horizontal scroll key button 1040 and a vertical scroll key button 1050 can be displayed in the vicinity of the change region polyhedron.

p-0170If a user manipulates a scroll key button 1045 corresponding to a horizontal clockwise direction, referring to <figref idrefs="DRAWINGS">FIG. 11</figref> (b), it is able to rotate the change region polyhedron 1000 in the corresponding direction.

p-0171In the following description, a method of enlarging/reducing a change region polyhedron is explained with reference to <figref idrefs="DRAWINGS">FIG. 12</figref>.

p-0172<figref idrefs="DRAWINGS">FIG. 12</figref> is a diagram for one example of a method of enlarging/reducing a change region polyhedron in a mobile terminal according to one embodiment of the present invention.

p-0173Referring to <figref idrefs="DRAWINGS">FIG. 12</figref> (a), assume a case that the enlarge/reduce mode icon 1015 in the icon box 1010 is selected in the situation similar to that shown in <figref idrefs="DRAWINGS">FIG. 10</figref> (a). Hence, an enlarge key button 1210 and a reduce key button 1220 can be displayed in the vicinity of the change region polyhedron.

p-0174If a user manipulates the enlarge key button 1210, referring to <figref idrefs="DRAWINGS">FIG. 12</figref> (b), an image displayed on each facet of the change region polyhedron 1000 can be enlarged. If a user manipulates the reduce key button 1220, referring to <figref idrefs="DRAWINGS">FIG. 12</figref> (c), an image displayed on each facet of the change region polyhedron 1000 can be reduced.

p-0175In the above described scrolling or enlarging/reducing method, the key button for performing each function preferably includes a virtual key button that can be manipulated via a touch input or a pointer by being displayed on the display unit. If the corresponding key button is not displayed on the display unit, it can be replaced by a prescribed hardware key button provided to the user input unit 130.

p-0176Meanwhile, in order to scroll or enlarge/reduce the change region polyhedron, it is able to use a touch input to the change region polyhedron instead of the key buttons described with reference to <figref idrefs="DRAWINGS">FIGS. 10 to 12</figref>. This is explained with reference to <figref idrefs="DRAWINGS">FIG. 13</figref> as follows.

p-0177<figref idrefs="DRAWINGS">FIG. 13</figref> is a diagram for one example of manipulating a change region polyhedron via a touch input in a mobile terminal according to one embodiment of the present invention.

p-0178Referring to <figref idrefs="DRAWINGS">FIG. 13</figref>, assume that the display unit 151, on which a change region polyhedron is displayed, includes a touchscreen.

p-0179Referring to <figref idrefs="DRAWINGS">FIG. 13</figref> (a), a user performs a touch & drag input in a following manner to rotate a change region polyhedron [<figref idrefs="DRAWINGS">FIG. 13</figref> (b)]. First of all, a user applies a touch input to one point on a change region polyhedron via a pointer 800, shifts the corresponding touch to another point by maintaining the touched state, and then releases the touch input.

p-0180Moreover, the user is able to enlarge an image displayed on each facet of the change region polyhedron [<figref idrefs="DRAWINGS">FIG. 13</figref> (d)] by a method (i.e., multiple touch & drag) of simultaneously applying touch & drag inputs to the change region polyhedron using two pointers 800 and 805 set to get farther from initially touched points, respectively [<figref idrefs="DRAWINGS">FIG. 13</figref> (c)]. In case that the touch & drag input is applied in a manner of getting closer to the initially touched point of each of the pointers, the image displayed on each facet of the change region polyhedron can be reduced.

p-0181Meanwhile, in another aspect of the present embodiment, it is able to enlarge one facet of a change region polyhedron again. This is explained with reference to <figref idrefs="DRAWINGS">FIG. 14</figref> as follows.

p-0182<figref idrefs="DRAWINGS">FIG. 14</figref> is a diagram for one example of a method of enlarging and displaying one facet of a change region polyhedron in a mobile terminal according to one embodiment of the present invention.

p-0183Referring to <figref idrefs="DRAWINGS">FIG. 14</figref>, assume a following situation. First of all, a change region polyhedron is displayed on a touchscreen. Secondly, the aforesaid icon box 1010 is not activated. Thirdly, the aforesaid manipulation of the change region polyhedron using the touch, which is described with reference to <figref idrefs="DRAWINGS">FIG. 13</figref>, is not applicable.

p-0184Referring to <figref idrefs="DRAWINGS">FIG. 14</figref> (a), when a change region polyhedron 1000 is displayed, it is able to designate a region 1410 to enlarge using a pointer 800 in order to enlarge an image displayed on a front facet of the change region polyhedron.

p-0185Accordingly, referring to <figref idrefs="DRAWINGS">FIG. 14</figref> (b), it is able to display an image generated from enlarging the designated region at a prescribed ratio in a manner that a 3D depth lower than that of the change region polyhedron 1000 is given to the displayed image.

p-0186Besides, the aforesaid method of enlarging at last one portion of the facet can be combined with the aforesaid change region polyhedron manipulating method in various ways.

p-0187Plural Change Region Polyhedrons

p-0188Meanwhile, according to another embodiment of the present invention, at least two change region polyhedrons are selected and can be then simultaneously or selectively displayed. For this, a method of generating a plurality of change region polyhedrons and display form of the change region polyhedrons are described with reference to <figref idrefs="DRAWINGS">FIG. 15</figref> and <figref idrefs="DRAWINGS">FIG. 16</figref> as follows, respectively.

p-0189<figref idrefs="DRAWINGS">FIG. 15</figref> is a diagram for one example of a method of selecting a plurality of display state change regions in a mobile terminal according to another embodiment of the present invention.

p-0190Referring to <figref idrefs="DRAWINGS">FIG. 15</figref>, assume the followings. First of all, the display unit 151 includes a touchscreen configured to recognize a user's touch input. Secondly, a display state change region has a cube form. Thirdly, the display state change region is selected in a manner of designating a rectangle becoming a base side of the cube and then giving a height to the designated base side. Fourthly, a 3D user interface displayed on a touchscreen is an application for informing a user of such perimeter location information a shown in <figref idrefs="DRAWINGS">FIG. 6</figref>.

p-0191Referring to <figref idrefs="DRAWINGS">FIG. 15</figref> (a), in order to designate a display state change region of a cube type to a 2D map, a user performs a drag input with a trace 1510 corresponding to a base side of the cube around a rectangular pillar type building using a pointer 1500.

p-0192If the base side of the cube is specified (i.e., a closed loop is completed in a manner that a drag trace meets a start point), it is able to display a menu window 1530 for querying whether a selection of the cube base side is completed [<figref idrefs="DRAWINGS">FIG. 15</figref> (b)]. In this case, the menu window 1530 includes a complete menu 1531 indicating a selection completion, an additional select menu 1531 indicating that another display state change region is additionally designated and a cancel menu 1537 for canceling a previous selection.

p-0193If the user selects the complete menu 1531, the routine goes to a step of determining a height from the selected base side (cf. <figref idrefs="DRAWINGS">FIG. 15</figref> (d)). If the cancel menu 1537 is selected by the user, the routine goes back to the step shown in <figref idrefs="DRAWINGS">FIG. 15</figref> (a).

p-0194If the user selects the additional select menu 1535, referring to <figref idrefs="DRAWINGS">FIG. 15</figref> (c), the menu window 1530 disappears and a prescribed visual effect is given to the previously selected base side 1550. In this case, the user is able to select a base side of a second display state change region by performing a drag input in a manner of drawing a closed loop with a trace 1560 corresponding to a perimeter of a triangular pillar type building.

p-0195If the selection of the second base side is completed, the menu window 1530, as shown in <figref idrefs="DRAWINGS">FIG. 15</figref> (b), is displayed again. In this case, assume that the user selects the complete menu 1531.

p-0196If the complete menu 1531 is selected, referring to <figref idrefs="DRAWINGS">FIG. 15</figref> (d), the 2D map is switched to a 3D map and the base sides 1550 and 1565 selected in the previous steps are displayed. In this case, it is able to determine a height of the corresponding display state change region by a drag input starting with one point 1555 of the base side 1550 selected as the rectangular pillar type building perimeter. In particular, a release point of the drag & touch input becomes the height of the corresponding display state change region.

p-0197If the height determination is completed, a prescribed visual effect 1580 is given to indicate that the display state change region has been determined [<figref idrefs="DRAWINGS">FIG. 15</figref> (e)]. And, a height of the second display state change region can be determined by a drag input starting with one point 1567 of the base side 1565 selected as the perimeter of the triangular pillar type building.

p-0198<figref idrefs="DRAWINGS">FIG. 15</figref> shows the method of selecting two display state change regions simultaneously, by which the present invention is non-limited. For example, after one display state change region has been selected, another display state change region can be selected additionally from the step shown in <figref idrefs="DRAWINGS">FIG. 15</figref> (c) by a prescribed menu manipulation.

p-0199<figref idrefs="DRAWINGS">FIG. 15</figref> shows how two display state change regions are selected, by which the present invention is non-limited. For example, it is apparent to those skilled in the art that more display state change regions should be selectable.

p-0200In the following description a form of displaying a change region polyhedron and method of changing a display state of the change region polyhedron are explained with reference to <figref idrefs="DRAWINGS">FIG. 16</figref>.

p-0201<figref idrefs="DRAWINGS">FIG. 16</figref> is a diagram for one example of a form of displaying a plurality of change region polyhedrons in a mobile terminal according to another embodiment of the present invention.

p-0202Referring to <figref idrefs="DRAWINGS">FIG. 16</figref>, assume a situation after completion of the steps shown in <figref idrefs="DRAWINGS">FIG. 15</figref>.

p-0203Referring to <figref idrefs="DRAWINGS">FIG. 16</figref> (a), two display state change regions are changed and displayed as change region polyhedrons 1610 and 1620, respectively. As mentioned in the foregoing description with reference to <figref idrefs="DRAWINGS">FIG. 9</figref> (b), a prescribed visual effect can be given to each of the change region polyhedrons. Moreover, as mentioned in the foregoing description with reference to <figref idrefs="DRAWINGS">FIGS. 10 to 12</figref>, the icon boxes 1630 and 1640 are displayed in the vicinity of the change region polyhedrons to change the display states of the polyhedrons, respectively. As the description of the icon box is similar to that of the former icon box, the redundant description shall be omitted from the following description for clarity. Besides, the former display state changing method described with reference to <figref idrefs="DRAWINGS">FIG. 13</figref> and <figref idrefs="DRAWINGS">FIG. 14</figref> are applicable as well.

p-0204Referring to <figref idrefs="DRAWINGS">FIG. 16</figref> (b), a form of displaying the change region polyhedrons is similar to that shown in <figref idrefs="DRAWINGS">FIG. 16</figref> (a). Yet, thumbnails 1650 and 1660 for the change region polyhedrons are additionally displayed. If a user selects the thumbnail 1660 corresponding to the change region polyhedron 1610 including the rectangular pillar type building using a pointer 1600, a prescribed visual effect can be given to the selected thumbnail 1660 to indicate the corresponding selection. Afterwards, the user is able to change the display state of the selected change region polyhedron 1610 via an icon box 1670 displayed in the vicinity of the corresponding thumbnail 1660.

p-0205In this case, referring to <figref idrefs="DRAWINGS">FIG. 16</figref> (c), if the user selects the thumbnail 1650 corresponding to the change region polyhedron 1620 including the triangular pillar type building, the change region polyhedron 1620 including the triangular pillar type building blocked by the change region polyhedron 1610 including the rectangular pillar type building is displayed on a highest level. In doing so, if each polyhedron is displayed as a 3D stereoscopic image, the 3D depth of the selected polyhedron is further lowered to enable the user to feel as if the selected polyhedron is closer to the user. Afterwards, if the user manipulates the icon box 1670, the controller 180 recognizes the manipulation as an input for changing the display state of the selected polyhedron 1620.
