FIG. 3 is a diagram showing a configuration example of an information display device according to the present invention, in which 1 is an information display device (information display). The information display device 1 includes a control unit 10 that controls the entire information display device 1, an operation unit 11 that accepts user operations, a display unit 13 that displays an image, and a display control unit 12 that controls the display of an image on the display unit 13.

In order to control the entire information display device 1, the control unit 10 has a CPU (Central Processing Unit) or MPU (Micro Processing Unit), RAM (Random Access Memory) as a work area, and a control program (operation unit 11 and display). It is composed of a control device such as a storage device that stores (including a program that performs information display processing in cooperation with the control unit 12). The program that performs the above information display processing can include a GUI (Graphical User Interface) for encouraging user operations such as an input setting operation for setting when inputting information. Of course, a part or all of the control unit 10 can be configured with dedicated hardware.

Examples of the storage device include a flash ROM (Read Only Memory), an EEPROM (Electrically Erasable and Programmable ROM), and a hard disk. A file to be displayed on the information display device 1 can also be stored in the above storage device. If all of the control unit 10 is configured with dedicated hardware, a separate storage device may be provided for storing files.

The display unit 13 is a portion for displaying an image, and can be configured by, for example, a display panel such as a liquid crystal display or an organic EL (electroluminescence) display. The display unit 13 of the information display device 1 can display not only images showing information such as characters and figures but also images such as photographs and moving images. The details of the control will be described later, but the display control unit 12 controls the display of the image on the display unit 13.

The operation unit 11 receives various user operations on the information display device 1. The control unit 10 controls the entire information display device 1 including the display control unit 12 so as to execute processing according to the user operation. This user operation also includes a user operation for inputting information, and the input information is passed to the display control unit 12 and displayed on the display unit 13 under the control of the display control unit 12.

Further, the input information is temporarily stored in the internal memory of the control unit 10 or the like for temporary storage, and is stored in the storage device of the control unit 10 according to a user operation or automatically. The input information is stored in the storage device as part of a file containing at least the currently displayed image, preferably as a part of a file containing the currently displayed image as a page. Further, the user operation received by the operation unit 11 includes a user operation for reading such a file, and when the operation unit 11 accepts the read operation, the control unit 10 detects it and reads the target. Part or all of the file is passed to the display control unit 12, and the display control unit 12 causes the display unit 13 to display a part or all of the file.

Further, the operation unit 11 may be configured to have an operation detection sensor such as a touch sensor superimposed on or built into the above display panel so that the operation detection sensor detects and accepts a user operation. In addition, the above program includes a handwriting input application that draws according to the detected coordinates and reflects it on the display on the display unit 13. With such a configuration, the information display device 1 can perform handwriting input and can function as a so-called electronic blackboard device. User operations such as input setting operations may be accepted with the GUI image displayed on the display panel.

In the following, the description will be made on the premise that the information display device 1 can input by handwriting, that is, the information display device 1 is an electronic whiteboard device, but the operation unit 11 inputs information by a separately provided pointing device, keyboard, or the like. It can also be configured to accept user operations, including operations. Further, the information display device 1 is not limited to the integrated type, and can be configured by, for example, a PC (personal computer) and a display device. In that case, the PC may include at least the control unit 10, the display device may include at least the display unit 13, and the functions may be distributed and mounted on the PC side and the display device side for other configurations.

If the information display device 1 is provided with a communication unit such as a network adapter, it can be connected to peripheral devices such as a scanner device, a printer device, and a multifunction device by a wired / wireless network such as LAN (Local Area Network). As a result, the image data read by the scanner device can be displayed on the information display device 1, and the image displayed on the information display device 1 can be printed on the printer device or the multifunction device.

With the above-described configuration, the information display device 1 can receive user operations and display according to the contents of the user operations. Then, in the information display device 1 of the present invention, the operation unit 11 can accept the predetermined selection movement operation described below.

The predetermined selection movement operation refers to an operation for selecting and moving a part or all of the image currently displayed on the display unit 13 as a movement target image, and refers to, for example, a scroll operation or a page switching operation. However, the predetermined selection movement operation is not limited to the page switching operation or the scroll operation. The page switching operation refers to a page forward operation or a page return operation, and is not limited to an operation of forward / backward in units of one page. For example, an operation of forward / backward in units of 1 / n pages with n as an integer of 2 or more. It may be. Note that performing the scrolling process on a page-by-page basis corresponds to the page switching process. Further, the image to be the target of the scroll operation or the page switching operation may be all or a part of the image currently displayed on the display unit 13 as described above, and if it is a part, it remains. The part (the part that does not become the image to be moved) corresponds to a menu image such as a handwriting input application.

Scrolling operation and page switching operation are operations such as touching an arbitrary place on the display screen of the display unit 13 and flipping it in the moving direction while touching it, or selecting a button displayed as a GUI image so that the user can select it. Etc. are applicable. Examples of the buttons as the GUI image include up / down / left / right scroll buttons, page forward buttons, and page back buttons.

The display control unit 12 executes display control for moving the image to be moved in response to the predetermined selection movement operation, so that the display unit 13 displays an image that has not been displayed due to the movement. Become. More specifically, the display control unit 12 has an internal memory, and it is possible to store an image of a drawing screen larger than the display screen of the display unit 13 in the internal memory. Then, the display control unit 12 outputs a stored image to the display screen (for example, the next page) in response to an image movement operation (the above-mentioned predetermined selection movement operation) such as page switching or scrolling from the operation unit 11. The image of is extracted and output to the display unit 13 for display.

Then, as one of the main features of the present invention, the operation unit 11 can accept a predetermined selection operation described below. The predetermined selection operation refers to an operation for selecting a part of the image currently displayed on the display unit 13 as a movement prohibited image, and the above part can be selected for moving prohibited image selection by a predetermined method. It may be an operation.

When a predetermined selection operation is accepted, the display control unit 12 selects the target image (a part of the currently displayed image) as the movement prohibited image. Here, when the display control unit 12 receives a predetermined selection operation, the display control unit 12 changes the display form of the image selected as the movement prohibited image from the display form before selection (reverse display, enclosing with a frame, etc.). It is preferable to execute such display control. Changing the display form means that the image area selected as the movement-prohibited image and another image area are expressed differently. For example, the former is highlighted, the former image area is surrounded by a frame, or the like. The former process such as changing the background color of the image area is applicable. However, even if the selection of the movement-prohibited image is not reflected in the display form, the display control unit 12 indicates that the selected image is in the selected state as the movement-prohibited image unlike other areas. If it can be identified, the following display control, which is one of the main features of the present invention, can be realized.

As one of the main features of the present invention, when the display control unit 12 accepts the predetermined selection movement operation in a state where the movement prohibition image is selected according to the predetermined selection operation, the movement prohibition image Is displayed at the current display position as it is (leaving the movement-prohibited image displayed), and the display control for moving the movement target image is executed.

Explaining the case of page-forwarding or page-returning, when a user accepts a page-forwarding (or page-returning) operation, the display control unit 12 usually responds to the operation and displays an image currently displayed on the display unit 13. Is controlled to switch to the image associated as the next page (or previous page) of the image. However, when the page forward or page back operation is accepted while the user has accepted a predetermined selection operation such as selecting a part (a part of the area) of the image currently displayed on the display unit 13. Controls to switch to the associated image as the next page (or previous page) while keeping the movement prohibited image (part of the above area) displayed.

Explaining the case of scrolling, when a scrolling operation is received from the user, the display control unit 12 normally controls the display unit 13 to switch the image currently displayed on the display unit 13 to the scrolled image. However, if a scroll operation is accepted while a predetermined selection operation such as selecting a part of the image currently displayed on the display unit 13 is accepted from the user, the movement prohibited image (part of the above area) is accepted. ) Is left displayed, and the image in the remaining area is controlled to be switched to the scrolled image.

Further, in addition to the page switching operation and the scroll operation, it is also possible to perform a moving operation by targeting a part of the area A (for example, window a) of the image currently displayed on the display unit 13 as a moving target. When the area B (for example, window b) displayed superimposed on the window a is selected as the movement prohibited image and the user operation to move the window a is performed, the window a is moved without changing the window b. If a user operation is performed to move window a onto window c by selecting an area C (for example, window c) that does not overlap with window a as a movement-prohibited image, window c remains as the background. Window a is displayed.

With the above display control, even when the information display device 1 accepts an image movement operation such as a scroll operation or a page switching operation, the information display device 1 excludes the desired image from the image to be moved and moves the image. Becomes possible. Therefore, if there is a part where the item that the user wants to keep is written, the user can exclude that part from the target of movement such as scrolling, and the part where the item is written at the same time as the information to be displayed after the movement such as scrolling is displayed. You will be able to display it.

Next, as a specific example, the information display process (including the information input process) executed by the information display device 1 which is equipped with the handwriting input application and functions as an electronic blackboard device will be described with reference to FIGS. 4 to 15. ..

4 and 5 are flow charts for explaining an example of this information display processing. Further, FIGS. 6 to 9 are diagrams for explaining an example of using the thumbtack function as a part of this information display processing. In particular, FIG. 6 shows a state in which an image of a certain page is displayed on the information display device of FIG. 3, and FIG. 7 shows a user opening a toolbar on the display screen and pasting a thumbtack from the display state of FIG. FIG. 8 shows an example of how the thumbtack is pasted, FIG. 8 shows another example of how the thumbtack is pasted, and FIG. 9 shows a state when the user performs a page feed operation from the display state of FIG. It is a figure which shows.

As shown in FIG. 6, an image 31 of a certain page is displayed on the display unit 13 of the information display device 1, and this image 31 shows text information such as "Renraku: Bring a lot of cloth". Assume that image 31a is included. All the information including the character information may be input by handwriting, or the document file created in advance may be read and displayed. Furthermore, as illustrated in Fig. 6, the part illustrated in print (the problem of arithmetic addition, the answer from a certain respondent, and image 31a) is created in a document file, read out and displayed. It may be created by writing the correctness of the answer by handwriting input.

The image 31 also displays a menu display button 31m for displaying a toolbar as a menu image by pop-up. When the user touches this menu display button 31m, the toolbar 33 is displayed as shown in FIG. On the toolbar 33 illustrated here, each icon of the pen icon 33a, the eraser icon 33b, the thumbtack icon 33c, and the setting icon 33d is displayed, and the user corresponds to the touched icon by touching any of them. The process can be selected. The toolbar 33 may be displayed from the beginning without arranging the menu display button 31m.

In the following, an example of information display processing will be described along the flow of FIGS. 4 and 5 by taking the case where the toolbar 33 is originally displayed as an example. Here, the page forward / backward processing will be described as an example, but it can be similarly applied to other image movement processing such as scroll processing.

First, the control unit 10 of the information display device 1 starts the handwriting input application and performs the initial setting (step S1). As an initial setting, for example, the item to be used is a pen (the item used when the above pen icon 33a is selected), and the size (thickness) can be set from 1 to 10, for example, "3". , And the color of the pen is "black".

Next, the control unit 10 determines whether or not there is a pen input (touch with a pen or a finger) (step S2), and if not (in the case of NO), proceeds to step S21 in FIG. 5, which will be described later. If (yes), it is determined whether or not the pen input is at the icon position (any of the icons 33a to 33d) (step S3).

If YES in step S3, the control unit 10 determines whether or not the pen has been pened up (touch by the pen or finger has been released) (step S4), and waits for the pen to be pened up. When the result is YES in step S4, the item in the pen-up area is determined (step S5). When the pen icon 33a is selected, that is, when the item is a pen, the control unit 10 sets the item as a pen (step S6) and returns to step S2. Similarly, when the eraser icon 33b is selected, that is, when the item is an eraser, the control unit 10 sets the item as an eraser (step S7) and returns to step S2. Similarly, when the thumbtack icon 33c is selected, that is, when the item is a thumbtack, the control unit 10 sets the item as a thumbtack (step S8) and returns to step S2. Similarly, when the setting icon 33d is selected, that is, when the item is a setting, the control unit 10 sets the item to the setting (step S9) and returns to step S2.

On the other hand, if NO in step S3, the control unit 10 determines what the set item is (step S10). When the item is set to the pen, the control unit 10 causes the line to be drawn at the position (coordinates) input by the pen (step S11). Actually, the input position may be detected at a predetermined time interval until the pen is up, and a line connecting the positions may be drawn. When the item is set to the eraser, the control unit 10 deletes the image at the pen input position (step S12). After the processing of steps S11 and 12, the control unit 10 determines whether or not the pen is up (step S15), returns to step S2 if YES, and returns to step S10 if NO. In this way, by continuing to draw or delete the line until it is pen-up, in the case of drawing, for example, it is possible to draw a circle indicating that the answer is correct in the formula "1 + 2 = 3". , In the case of deletion, the image at the input position can be continuously deleted.

As a result of the determination in step S10, if the item is set as a thumbtack, the control unit 10 uses the thumbtack function for the input position (step S13) and returns to step S2. If the item is set to the setting, the control unit 10 displays a GUI image (not shown) of the setting screen (step S14), and returns to step S2. In the GUI image of the setting screen, for example, the color and thickness of the pen may be selectable, and the setting contents selected by the operation unit 11 may be saved in the internal memory of the control unit 10.

Specific examples of steps S8 and S13 will be described. As an example of the case where the user wants to keep the items on the display screen, the case where the user wants to keep the information shown in image 31a will be described. In this case, the user touches the thumbtack icon 33c in step S8, returns to step S2, and touches the vicinity where the items to be left are displayed in step S2. In this state, it can be determined that the set item is a thumbtack in step S10, and the process proceeds to step S13. In step S13, as shown in FIG. 7, the thumbtack icon 34 is pasted at that position as a result.

In this example, the predetermined selection operation is an operation specified by pasting a predetermined image such as a thumbtack icon 34 at the position of the image to be selected as the movement prohibited image. However, as the predetermined selection operation, the predetermined image is selected. After selection, you may specify the prohibition of movement. Further, when the desired position is touched, a menu image is displayed, and an operation such as selecting a thumbtack paste from the menu image can be adopted.

At this stage, only the thumbtack icon 34 is pasted, so the display control unit 12 selects an image in a predetermined range including a predetermined image such as the pasted thumbtack icon 34 as the movement prohibited image. You can select a movement-prohibited image by performing various processing. How to determine the predetermined range will be described later with reference to FIGS. 12 to 15, but it may be determined automatically or manually. Here, the description will proceed assuming that the predetermined range is determined to be a rectangular range including the image 31a and the thumbtack icon 34.

Further, instead of the example of FIG. 7, as illustrated in FIG. 8, when the display control unit 12 accepts the above-mentioned predetermined selection operation, the image selected as the movement prohibited image (that is, the applicable range of the thumbtack function). By changing the background color of 35, the display form may be changed from the display form before selection.

Next, the processing when NO in step S2, that is, when the input is not pen input, will be described with reference to FIG. In this case, the control unit 10 determines whether or not there is a page forward / return instruction from the user (step S21), and if YES, determines whether or not there is a page to which the instruction is given (step). S22). If NO in steps S21 and S22, the process returns to step S2.

If YES in step S22, the display control unit 12 determines whether or not there is a movement prohibited image (step 23). If NO in step S23, the display control unit 12 executes page forward / backward processing for all images on the displayed page (step S25), and returns to step S2. By the process of step S25, for example, only the image 32 on the next page as shown in FIG. 11 described later is displayed.

On the other hand, if YES in step S23, that is, when a page forward / return operation is received from the user with the movement prohibited image selected, the display control unit 12 performs the page forward / return process except for the movement prohibited image. Execute (step S24) and return to step S2. Explaining by the page feed operation, in step S24, as illustrated in FIG. 9, the images other than the image 31a and the thumbtack icon 34 are page feedd, and the image 32 of the next page is displayed on the display unit 13. That is, by the process of step S24, the images of the thumbtack 31a and the thumbtack icon 34 are displayed in the foreground of the image 32 on the next page.

The movement prohibited image is an image selected by the user by the above-mentioned predetermined selection operation, whereas the menu display button 31m and the toolbar 33 are not included in the moving target image and are handwritten input applications so as not to move originally. It is an image determined in the above, and does not correspond to an image selected by the above-mentioned predetermined selection operation by the user.

Next, an example of the procedure for turning off the thumbtack function will be described with reference to FIGS. 10 and 11. FIG. 10 is a diagram showing a user removing a thumbtack on the display screen from the display state of FIG. 8, and FIG. 11 is a diagram showing the thumbtack being removed as shown in FIG. It is a figure which shows the state when a user performs a page feed operation.

It is preferable that the operation unit 11 can accept from the user an operation of removing the predetermined image such as the thumbtack icon 34. As the operation for removing the thumbtack, for example, an operation of touching the thumbtack icon 34 of the target after touching the icon 33d for taking out the thumbtack from the setting screen can be adopted. Other operations for removing include a method of deleting the thumbtack icon 34 by touching the thumbtack icon 34 again, a method of dragging the thumbtack icon 34 and moving it to a trash can icon (not shown), and the like.

Immediately after performing such a removal operation, the display control unit 12 displays the setting icon 36 similar to the setting icon 33d at the position of the thumbtack icon 34 as shown in FIG. 10, and displays it as shown in the image 31b. By superimposing and displaying the slightly shifted images, the user may be shown that the images have been removed in an easy-to-understand manner. Then, when the display control unit 12 accepts the operation of removing the predetermined image, the display control unit 12 cancels the selection of the movement prohibited image (turns off the thumbtack function). That is, the selection of the movement prohibited image is canceled when the operation of removing the predetermined image is accepted.

Further, it is preferable to return the background color of the application range of the thumbtack function (predetermined range above) to the original background color at the stage when the thumbtack function is turned off or immediately after accepting the removal operation as shown in FIG. .. The thumbtack icon 34 can be pasted at a plurality of positions, and it is sufficient to deselect only the movement-prohibited image including the thumbtack icon 34 at the position where the removal operation is performed when removing the thumbtack icon 34.

When a predetermined selection movement operation is accepted after the thumbtack function is turned off in this way, the display control unit 12 executes the process of step S25 in FIG. 5, that is, the display control for simply moving the image to be moved. do it. When the predetermined selection movement operation is page feed, only the image 32 of the next page is displayed on the display unit 13 as shown in FIG.

Next, with reference to FIGS. 12 to 15, how the display control unit 12 determines a predetermined range including a predetermined image such as the thumbtack icon 34 to which the display control unit 12 is attached will be described. When the movement prohibited image is determined by determining the predetermined range, it is preferable to change the display form such as changing the background color as described above.

FIG. 12 is a diagram showing another example in which the user opens the toolbar on the display screen and pastes the thumbtack from the display state of FIG. As a method of determining the movement prohibited image, it is preferable to adopt a method of automatically determining the image as described later, but a method of not automatically determining (that is, a method of manually determining) can also be adopted. For that purpose, as shown in FIG. 12, the icon 33e for the user to specify the applicable range (the above-mentioned predetermined range) may be displayed on the toolbar 33 so as to be selectable. The icon 33e may have a shape that can be understood as an icon for specifying a range by a dotted line frame or the like. Then, the user can manually determine an arbitrary range as the applicable range by touching and dragging the icon 33e after selecting it. After the applicable range is determined in this way, the image of the applicable range is determined as the movement prohibited image by designating with the thumbtack icon 34.

In addition, as another manual determination method, the thumbtack icon 33c is not provided, only the icon 33e is provided, and after the icon 33e is touched, the area specification (range specification) is accepted and the applicable range is applied to the accepted range. You may decide. In any of the determination methods, the predetermined selection operation corresponds to the operation of pasting the predetermined image at the position of the image to be selected as the movement prohibited image and designating the range so as to include the position. Based on the operation of specifying this range, the image in this range is automatically selected as the movement prohibited image.

Next, a method for automatically determining the determination will be described with reference to FIGS. 13 and 14. FIG. 13 is a diagram for explaining an example of a method of determining the range of the movement prohibited image when the user attaches a thumbtack on the display screen as in the display state of FIG. 7 in the information display device of FIG. FIG. 14 is a diagram for explaining another example of this method.

As a method of automatically determining the applicable range, an object such as a character or a figure existing around the position where the thumbtack icon 34 is attached may be searched, and the boundary may be determined from the search result. Here, objects such as characters and figures may be input by handwriting. Then, as such a determination method, for example, either the first determination method shown in FIG. 13 or the second determination method shown in FIG. 14 can be adopted.

First, the first determination method will be described with reference to FIG. Search for the characters around the thumbtack icon 34, find the closest character "ku" ("ku" in "renraku:"), and measure the distance between that character and other characters adjacent to that character. The measurement of such an interval is repeated, and the place where the character interval becomes wider than a predetermined value is recognized as a boundary. For example, it is assumed that the interval 42 is within a predetermined value, but the interval 41 between the image 31a and the character string of the title "1 Jikanme Sansu" and the interval 43 between the image 31a and the image 31c are wider than the predetermined values. In such a case, no boundary is provided at the interval 42, and a boundary is provided at the interval 41 or the interval 43 to determine the applicable range.

Here, the control unit 10 performs processing on the premise that the predetermined selection operation is an operation for designating the position of the image to be selected as the movement prohibited image. In addition, instead of the above position, a range selected in an area such as touching and dragging can be adopted.

Next, the second determination method will be described with reference to FIG. In the second determination method as well as in the first determination method, the distance between the objects is obtained, and the applicable range, that is, the movement prohibited image is determined based on the distance. The second determination method also includes a determination to be used when the determination cannot be made by itself. In the second determination method, character recognition and semantic analysis are executed to determine whether or not the preceding and following sentences can be communicated, and the range up to the point where the sentences can be communicated is determined as the applicable range. For example, the line spacing 44 in FIG. 14 is judged as a boundary because the meaning is understood, and the line spacing 45 is judged as a boundary because the meaning is not understood.

Next, if the applicable range cannot be determined automatically, the display control unit 12 should display the GUI image 51 illustrated in FIG. 15 so that the user can specify the range as shown in FIG. Just do it.

The information display device according to the present invention has been described above, but as described in the processing procedure, the present invention has an operation unit that accepts user operations, a display unit that displays an image, and an image display on the display unit. There is also a form as an information display method in an information display device including a display control unit for controlling.

This information display method includes the following first reception step, second reception step, and display control step. The first reception step is a step in which the operation unit receives a predetermined selection operation for selecting a part of the currently displayed image as a movement prohibited image. The second reception step is for the operation unit to select and move a part or all of the currently displayed image as a movement target image in a state where the movement prohibited image is selected in response to the predetermined selection operation. This is a step of accepting a predetermined selection movement operation of. In the display control step, when the predetermined selection movement operation is received in the second reception step, the display control unit moves the movement target image in a state where the movement prohibited image is displayed as it is at the current display position. This is the step of executing the display control to be performed. Other application examples and effects are as described for the information display device, and the description thereof will be omitted.

Further, the present invention also refers to a program for causing the control device in the information display device to execute the first reception step, the second reception step, and the display control step in the above information display method (that is, refer to FIGS. 4 and 5). It can also be in the form of a program) that performs the above information display processing as illustrated. The function according to the present invention can be realized by storing the program for performing the above information display processing in the storage device of the control unit, reading the program from the storage device, and executing the program.

The present invention may also take the form of a computer-readable recording medium that stores these programs. Examples of this recording medium include portable recording media such as CD (Compact Disc), DVD (Digital Versatile Disc), BD (Blu-ray Disc), and Universal Serial Bus (USB: registered trademark) memory. In this embodiment, the program is read from the above-mentioned recording medium by the control device and executed, or is read from the above-mentioned recording medium by the control device and stored in the storage device of the control device, and is read from the storage device and executed. By doing so, the function according to the present invention can be realized.
