Display device, display method, display program, and recording medium with the program recorded thereon

The present invention relates to a display device, a display method, a display program, and a recording medium on which the display program is recorded, and can be applied to, for example, a car navigation device. The present invention starts scrolling while zooming out the display of the display target according to the scroll instruction, zooms in to the original size and ends scrolling, or zooms in to the original size by the end of scrolling. , The scrolling of the display improves usability compared to the past.

Conventionally, in a car navigation device, a map is displayed to guide a user to a destination. In such a car navigation device, the display of this map is scrolled in response to an operation by the user, so that it can be used for searching and confirming a destination.

Various ideas have been proposed for such scrolling. For example, Japanese Patent Application Laid-Open No. 2000-292194 describes operability related to scrolling by switching the scrolling speed in response to an operation by a user. It has been proposed how to improve.

However, in a conventional car navigation device, when a point farther than the currently displayed point is displayed by scrolling the display, it is necessary to scroll the display for a longer time, which causes a problem of inconvenience. .. By the way, if the scrolling speed is increased in order to solve this problem, it becomes difficult to grasp the displayed contents, and the usability becomes worse.

Further, when scrolling such a long distance, it becomes difficult to grasp the positional relationship between the point displayed up to that point and the target point, which also causes a problem of inconvenience. It should be noted that such grasping of the positional relationship becomes remarkable when there is no sense of land regarding the points displayed up to that point and the target points, and when the scale is not displayed.

In such a case, in a conventional car navigation device, the display is zoomed out to reduce the scale of the map display, the display is scrolled so that the target point is the center of the display, and then the map is zoomed in. It is conceivable to return the display to the original scale. In this way, the time required for scrolling can be shortened by the amount of zooming out. In addition, the zoom-out display makes it possible to easily grasp the positional relationship between the previously displayed point and the target point. However, when performing the zoom-out, scroll, and zoom-in operations in this way, there is a problem that the operations become extremely complicated. In particular, it also hinders driving while driving.<patcit num="1"><text>Japanese Unexamined Patent Publication No. 2000-292194</text></patcit>

Performs navigation processing and provides various contents to users. Here, in this embodiment, although the program related to the processing of the controller 33 is installed and provided in the car navigation device 1 in advance, instead of such an installation in advance, a network such as the Internet is used. It may be provided by downloading via, or it may be provided by installation using various recording media. Incidentally, as such a recording medium, various recording media such as an optical disk, a magnetic disk, and a memory card can be widely applied.

That is, when the user instructs the controller 33 to provide the content, the controller 33 responds to the operation by the user and displays the video content, the music content, etc. obtained from the tuner unit 23, the optical disk drive 24, the hard disk device 35, and the car audio. Provided via device 28. When instructed to browse the Internet, the browser software is started to connect to the Internet by the communication unit 34, the video and the like obtained from the communication unit 34 are displayed on the display unit 37, and the audio data is output by the output unit 27.

When a process related to e-mail is instructed, the mailer is started to display the e-mail held in the hard disk device 35 on the display unit 37, and the e-mail used for such display is displayed via the communication unit 34. get. It also accepts user input of e-mail and sends this e-mail via the communication unit 34. When the viewing of the still image is instructed, the still image file related to the processing target is acquired from the memory card 32 and the hard disk device 35, and the still image related to the still image file is displayed on the display unit 37.

On the other hand, when the user instructs to display the map, the information of the current position is acquired from the GPS unit 22, and the map data recorded in the hard disk device 35 is loaded based on the information of the current position. In addition, the map is displayed on the display unit 37 based on the loaded map data. When the user instructs the navigation process, the user accepts the input of the destination and the like, acquires the information of the current position from the GPS unit 22, and executes the route search process based on this information. The controller 33 displays a map according to the user's settings and outputs various information so as to guide the user by the route detected in this way.

With the map displayed in this way, the controller 33 enlarges or reduces the display of this map by operating the remote commander 40 or by operating the touch panel 39, and changes the map display format to, for example, a bird's-eye view format. Switch. In these processes, when the user is instructed to scroll the map display, the map display is scrolled while being zoomed out by executing the process procedure shown in FIG. 1, and then the map display is zoomed in to the original scale. Here, the scroll instruction by the remote commander 40 includes, for example, an operation of Joyce Tech provided on the remote commander 40, an operation of a pressing operator for instructing the scroll direction, and the like. Further, in the scroll instruction by the operation of the touch panel 39, the operation of touching the position displaced from the center of the display screen with a finger or the like in the direction desired to be displayed by scrolling, or the direction desired to be displayed by scrolling. After sliding the finger or the like touched from the center of the screen, the touch panel 39 is kept in contact with the touch panel 39 only during the scrolling time.

When the operation of the remote commander 40 and the touch panel 39 by the user is detected, the controller 33 starts this processing procedure and moves from step SP1 to step SP2, where whether or not the operation by this user is an operation instructing scrolling. to decide. If a negative result is obtained here, the controller 33 moves from step SP2 to step SP3 and ends this processing procedure.

On the other hand, if an affirmative result is obtained in step SP2, the controller 33 moves from step SP2 to step SP4, where the screen display is scrolled in the scroll direction according to the instruction by the user. In the following step SP5, it is determined whether or not the current zoom-out scale at the time of scrolling is a preset limit value, and if a negative result is obtained here, the controller 33 moves from step SP5 to step SP6. .. Here, the controller 33 reduces the scale of the map display by the amount of scrolling by step SP4 and zooms out the map display. As a result, the controller 33 shifts the center of the zoom-out by the amount of scrolling to display the display unit 37 so as to show the map displayed by the display unit 37 by the symbol L2 in comparison with the reference numeral L1 according to FIG. Zoom out to expand the area displayed by the map in the scrolling direction instructed by the user.

On the other hand, if a positive result is obtained in step SP5, the controller 33 moves directly from step SP5 to step SP7. As a result, when the scale of the map display reaches this limit value, the controller 33 stops the zoom-out process and simply scrolls the map display.

Subsequently, the controller 33 determines in step SP7 whether or not the scrolling operation by the user has been stopped, and if a negative result is obtained here, the controller 33 returns from step SP7 to step SP4.

As a result, the controller 33 repeats the processing procedure of steps SP4-SP5-SP6-SP7-SP4, and scrolls by the user so as to roughly show the change of the map displayed by the display unit 37 by the symbols L1 to L5 in FIG. According to the instruction of, the center of the zoom-out is sequentially displaced in the direction opposite to the scrolling direction to zoom out the display of the display unit 37, thereby displaying the area displayed by the map in the scrolling direction instructed by the user. And scroll out the map display while zooming out. When the scale due to such zoom-out reaches a preset limit value, the processing procedure of steps SP4-SP5-SP7-SP4 is repeated, zoom-out is stopped, and the map display is scrolled.

It should be noted that the limit value related to the judgment of step SP5 is the scale value of the map display when zoomed out to the maximum by the user's preset setting, the setting of the program related to this series of processing, and the like. This limit value may be set so as to have a constant magnification with respect to the scale of the map display at the start of scrolling, in addition to the case where it is simply set by the scale value. Also, for example, from the record of past use, the setting of the limit value is changed as appropriate according to the past distance that becomes the limit value and the map display is simply scrolled, and the so-called learning function is suitable for the user's use. It may be set to a limit value.

When the scroll-out is sequentially zoomed out in this way and the scroll instruction is stopped by the user, the controller 33 moves from step SP7 to step SP8, and the scale of the map display is increased, contrary to the case of zoom-out. This causes the zoom-in process to be executed. Here, in this embodiment, the controller 33 sets the center of the zoom-in to the center of the display screen by the display unit 37, and executes the zoom-in process. Further, in the following step SP9, it is determined whether or not the scale of the map display has returned to the scale before the start of this processing procedure by this zoom-in process, and if a negative result is obtained here, the process returns to step SP7.

As a result, the map display is returned to the original scale so as to roughly show the change of the map displayed by the display unit 37 by the symbols L6 to L10 in FIG. 5 in comparison with FIG.

In these processes, the controller 33 executes zoom-out and zoom-in processes so that the scale changes continuously, so that the changes in the image due to zoom-out and zoom-in can be seen smoothly. In addition, the zoom-out and zoom-in processes are executed so that the change in scale becomes linear, that is, the scale is expressed by a temporary function in which time is set as a variable, which causes a sense of discomfort when zooming out and zooming in. Don't feel it.

Further, in the map display on the display unit 37, the scroll amount is set so that the movement speed of the map display in the center of the screen becomes a constant value, and the zoom-out process is executed. As a result, the scroll process is executed without zooming out at all. It is designed to shorten the time until the destination is displayed compared to the case where the destination is displayed. As a result, in this embodiment, in the actual terrain corresponding to the center of the screen, the moving speed is gradually increased by decreasing the scale.

In addition, a mark indicating the area displayed at the original scale is displayed so as to show the state in which the scale is sequentially reduced according to FIGS. 6 (A) to 6 (C). Specifically, in this embodiment, when the scale with respect to the original display is equal to or less than a predetermined value, as shown in FIG. 6 (A), the area displayed at the original scale is surrounded by the four corners of this area. Display by. When this scale becomes smaller, as shown in Fig. 6 (B), the area displayed at the original scale is displayed by rectangular hatching, and when the scale becomes smaller, the area is displayed. As shown in Fig. 6 (C), the position of the area displayed at the original scale is displayed by the cursor with line segments extending in the horizontal and vertical directions.

Further, the controller 33 also forms a display indicating the scale of the map corresponding to each of these scales on the display screen of the display unit 37. In the examples of FIGS. 6 (A) to 6 (C), this display is displayed according to the distance in the map display.

Then, when the zoom-in is sequentially performed in this way and the scale is returned to the original scale, the controller 33 moves from step SP9 to step SP3 and ends this processing procedure. On the other hand, if the user instructs scrolling again while zooming in, it is considered that the target value protrudes from the display screen by the display unit 37 in the zoom-in process. In this case, the controller 33 , When a negative result is obtained in step SP7, the user returns to step SP4 and scrolls the map display while zooming out again according to the scroll instruction by the user.

As a result, in this embodiment, when the destination is detected by scrolling the map, the time required for scrolling is set so that the user can grasp the displayed contents by the amount of scrolling while zooming out. It is designed to be shortened. In addition, the positional relationship with respect to the destination can be easily grasped as compared with the conventional case.

Then, the controller 33 responds to the operation by the user, displays a cursor, an icon, etc. on the map displayed in this way, accepts the setting of the destination related to the navigation process, and further, the facility and the store. It is designed to display detailed information.

On the other hand, in the operation related to navigation, when the user instructs the route simulation, the controller 33 scrolls the display screen so as to follow the route from the current position to the destination. In this scrolling process, the controller 33 scrolls the map display while zooming out in the same manner as described above for the scrolling operation by the user. Also, zoom in near the destination to return the map display to the original scale and end scrolling. Also, during this scrolling, the map display is temporarily zoomed in according to the degree of attention on the route.

Here, the degree of attention is a parameter indicating the degree to which the user is alerted to the points on the map displayed by the car navigation device 1. The degree of attention is set to a large value for points that require caution when driving, whereas it is set to a large value for, for example, urban areas, intersections, junctions, toll road gates, etc. , For winding straight roads, sharp curves, etc., it is set to a medium value, and for straight roads, mountainous areas, highways, etc., it is set to a small value. The degree of attention is also set for facilities, stores, etc. that are expected to be used by users when moving. In this case, for example, parking areas and service areas have large values depending on the degree of expected use. On the other hand, for gas stations and convenience stores facing general roads, medium values are set. In addition to these, various entertainment facilities such as restaurants may be added to the target of setting the degree of attention. In this case, it is conceivable to determine the user's preference from various destinations, waypoints, stop-by history, etc. by the user, and set the degree of attention for each genre according to this preference. The controller 33 is designed so that points, facilities, etc. for which these attention levels are set are registered and held in advance together with the attention levels.

The controller 33 temporarily zooms in on the map display according to the degree of attention by executing the processing procedure shown in FIG. 7. That is, when the user instructs the route simulation, the controller 33 starts this processing procedure and moves from step SP11 to step SP12. Here, the controller 33 detects points, facilities, etc. existing in a predetermined range along the road of the route from the current position to the destination from the registered points, facilities, etc. related to the degree of attention. Further, in the following step SP13, each point detected in this way, the corresponding point from the attention level of the facility, and the scale for displaying the facility in the center of the display screen of the display unit 37 are determined. Here, in this embodiment, the attention level is a parameter indicating the degree of attention to the user, and therefore, the larger the degree of drawing the user's attention, the larger the value is set, whereby the controller 33 is set to the attention level. The larger the value, the larger the scale of the display.

As a result, for example, as shown in FIG. 8, when the route simulation from the current position indicated by the triangle mark to the destination indicated by the circle mark is instructed, attention should be paid so that the display area is indicated by the rectangle indicated by the symbols A to G. Set the scale of the map display of each point related to the setting of the degree. However, in the example shown in FIG. 8, the current position and destination indicated by the symbols A and G are set to the scale at which the degree of attention is highest, and the intersections indicated by the symbols C, D, and F are present. Is set to a degree of attention with a small value compared to the current position and destination, respectively, so that at these points C, D, and F, the scale of display is set smaller than that of the current position and destination. It is made to be.

When the controller 33 sets the display scale for each attention level setting location in this way, the controller 33 proceeds to step SP14, and sets a change in the display scale for the route related to this route simulation by this setting. Here, as shown in FIG. 9, the controller 33 displays the map of each attention level setting location for a certain period of time according to the scale related to this setting, and the front and back, the vicinity of the current position, and the purpose of each attention level setting location. The scale is set to change according to a predetermined rate of change in the vicinity of the ground. At this time, the scale related to the route is set by setting a limit value for the zoom out in the same manner as described above for the processing procedure shown in FIG. In this case as well, the controller 33 sets the scale so that the change in the scale becomes linear, that is, the scale is expressed by a temporary function in which the time is set as a variable.

As a result, in the subsequent step SP15, the controller 33 zooms out and zooms in according to the scale set in this way to display the map, and also provides the display so that the moving speed on the display of the map becomes a constant value. After moving the position on the map along the route and executing the scrolling process while appropriately changing the scale of the display, the process proceeds to step SP16 to end this processing procedure. As a result, in the scroll processing related to the processing procedure shown in FIG. 1, the scroll is zoomed in by the end of the scroll, whereas in the scroll process by this route simulation, the scroll is zoomed in to the original magnification and the scroll is terminated. ing.

(2) Operation of the embodiment In the above configuration, in the car navigation device 1, a map is displayed on the display unit 37 according to an instruction by the user, and the user is guided to the destination using this map. As a result, the user can confirm the current position by displaying this map, and further scroll the map display to confirm the surrounding geography and discover the target facility. In some cases, the display of this map is scrolled to set the destination.

In these cases, if the display screen is simply scrolled as in the conventional case, it takes time to scroll, and it becomes difficult to grasp the relationship between the current position and the discovered destination. In order to avoid such a situation, it is necessary to repeat the operations of zooming out, scrolling, and zooming in.

Therefore, in this embodiment, when the user instructs scrolling, scrolling is started while zooming out the map display, and scrolling is completed to zoom in to the original size. As a result, in the display of this map, it is possible to prevent deterioration of visibility for the user by scrolling at a higher speed by the amount of zooming out, as compared with the case of scrolling at the original scale by a simple operation. As a result, the time required for scrolling can be shortened as compared with the conventional case, and the usability can be improved.

Also, in the case of scrolling in this way, when scrolling is stopped, it is the case that the destination is found with the magnification reduced to a certain scale, which makes it easy to relate to the current position. This can also improve usability.

In addition, scrolling is performed while zooming out in this way, and a certain limit value is set for the scale of zooming out, so that, for example, the direction can be switched up / down / left / right without finding the destination. Even when scrolling is performed for a long time, it is possible to search for a destination or the like at a practically sufficient scale by preventing a significant decrease in scale, which also improves usability.

On the other hand, in the route simulation process, which is the scroll process when the scroll direction is already known, the point where the attention is set is along the route because the process is used by the user to confirm the route. It is detected, and the zoom-in and zoom-out processes are temporarily executed and the scroll process is executed so as to display the map of the place where the attention level is set by the scale corresponding to the detected attention level. In this case, scrolling is started while zooming out the map display, and scrolling is ended by zooming in to the original size. This also makes it possible to scroll at a higher speed by preventing deterioration of visibility for the user compared to the case of scrolling at the original scale and simulating the route, which makes it possible to scroll at a higher speed than before. Compared to this, it can be shortened to improve usability. In addition, the relationship with the current position can be easily grasped. In addition, by temporarily zooming in according to the degree of attention, various information required by the route simulation can be effectively and surely notified to the user, which can further improve usability.

(3) Effect of Examples According to the above configuration, scrolling is started while zooming out the display to be displayed according to the scroll instruction, and the scroll is terminated by zooming in to the original size, or zooming in to the original size by the end of scrolling. By doing so, it is possible to improve usability with respect to scrolling of the display as compared with the conventional case.

In addition, when scrolling in this way, by temporarily performing zoom-in / zoom-out processing so that the map of the corresponding part is displayed at a scale that corresponds to the degree of attention, it is shortened in this way. By making it possible to scroll by time, it is possible to effectively and surely notify various information required by the user, which can further improve usability.

Further, since the display target to be used for such scrolling is a map, it can be applied to the display of the map and further applied to the car navigation device to improve the usability.

In the car navigation device according to this embodiment, in the above-described configurations of FIGS. 1 and 2, the scroll speed can be controlled by operating the remote commander 40 and the touch panel 39, and the remote commander 40 and the touch panel 39 can be operated. The scroll speed and zoom processing during scrolling are switched in response to the scroll operation instructed by the operation. Here, in the operation of the scroll speed related to the remote commander 40, for example, the operation amount of Joyce Tech provided in the remote commander 40 can be changed, the pressing force of the pressing operator indicating the scrolling direction can be changed, and the like. Further, in the operation of the scroll speed related to the touch panel 39, for example, the pressing force of the touch panel 39 can be changed. Therefore, in the car navigation device 1 according to this embodiment, in addition to the mechanism for detecting the scroll direction, a mechanism for detecting the scroll amount is provided in the configuration of the remote commander 40, the touch panel 39, and the like. The car navigation device according to the embodiment is configured to be the same as the car navigation device 1 according to the first embodiment except that the configurations related to the processing of the scroll speed are different. The configurations of FIGS. 2 and 3 will be described as appropriate.

In this embodiment, when the controller 33 is instructed to scroll by operating the remote commander 40 and the touch panel 39 while the map is displayed, the controller 33 zooms out in the same manner as described above for FIGS. 1 and 4 to 6. While scrolling is started, the map display is zoomed up to the original scale by the end of scrolling.

In this series of processes, the attention level is set for the points displayed by scrolling according to the scroll speed instructed by the user, and the attention level is set in the same manner as described above for FIGS. 8 and 9. Temporarily zoom in on the map display. As a result, when the user is instructed to scroll at a slow speed, a detailed map is displayed at a larger scale. On the contrary, when the user is instructed to scroll at a high speed, a large area is displayed on a map at a smaller scale. Instead of setting the degree of attention, the zoom-in / zoom-out process may be executed according to the scroll speed instructed by the user by changing the limit value at the time of scrolling described above.

Further, in this embodiment, the scroll speed instruction by the user is also accepted in the route simulation process, which is the scroll process when the scroll direction is already known. In this case, the attention level according to the scroll speed is received. Similarly, by setting the above, by changing the limit value according to the scroll speed, and by biasing the scale due to the change characteristic of the display speed described above with respect to FIG. 9 as a whole by the instruction of the scroll speed by the user. Performs zoom-in / zoom-out processing according to the scroll speed instructed by the user.

According to this embodiment, scrolling is started while the display to be displayed is zoomed out according to the scroll instruction, the scroll is zoomed in to the original size and the scroll is finished, or the scroll is finished to zoom in to the original size. By further performing zoom-in and zoom-out processing according to the scroll speed instructed by the user, the scroll processing can further reflect the user's intention and further improve usability. it can.

That is, when the scrolling speed is slow, the user wants to check the map display in detail. In this case, by zooming in from the previous state and displaying the map so that the scale becomes large, the map is displayed. The usability of the user can be improved. In addition, when the scrolling speed is high, it is considered that the map is scrolled quickly to display the vicinity of the destination, etc., and in this case, the scale is larger than that when the scrolling speed is slow. By displaying the map and scrolling, it is possible to improve the usability of the user.

In the above-described embodiment, the case where the scale changes linearly, that is, the scale at the time of zooming out and zooming in is set by a linear function in which the time is set as a variable has been described. Not limited to this, when a quadratic function, an exponential function, or the like is applied instead of the linear function, the characteristics of the change in scale at the time of zooming out or zooming in can be set in various ways as needed. Further, instead of the scale related to the display, the time may be set as a variable to express the size of the display area, and the change in the scale at the time of zooming out or zooming in may be set.

Further, in the above-described embodiment, the case where the present invention is applied to a normal flat map display has been described, but the present invention is not limited to this, and can be widely applied to a map display in a so-called bird's-eye view format.

Further, in the above-described embodiment, the case where the area to be displayed is enlarged in the scrolling direction and the zoom-in is centered on the center of the display screen has been described, but the present invention is not limited to this. The center of the zoom-out and zoom-in may be changed in various ways as needed.

Further, in the above-described embodiment, the case where the present invention is applied to the display of a map in a car navigation device has been described, but the present invention is not limited to this, and the map display in various devices such as a map display in a personal computer or the like is described.
