  The controller 33 is an arithmetic processing means, and in response to a user operation by executing a program recorded in the hard disk device 35 in response to an operation of the remote commander 40 detected via the input unit 38. It performs navigation processing and provides various contents to users. In this embodiment, the program relating to the processing of the controller 33 is provided in advance by being installed in the car navigation apparatus 1, but instead of such a prior installation, a network such as the Internet. It may be provided by downloading via the Internet, or 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 is instructed to provide content, the controller 33 displays video content, music content, and the like obtained from the tuner unit 23, the optical disc drive 24, and the hard disk device 35 in response to an operation by the user, the display unit 37, and the car audio.

When a still image browsing instruction is issued, a 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 display of the map is instructed by the user, the current position information is acquired from the GPS unit 22, and the map data recorded in the hard disk device 35 is loaded with reference to the current position information. A map is displayed on the display unit 37 by the loaded map data. When the navigation process is instructed by the user, the user receives an input of a destination or the like, acquires information on the current position from the GPS unit 22, and executes a route search process based on these information. The controller 33 outputs a variety of information by displaying a map in accordance with the setting of the user so as to guide the user along the route thus detected.

  When the controller 33 is instructed to scroll the map display by the operation of the remote commander 40 or the operation of the touch panel 39 with the map displayed in this manner, the map display is performed in response to the instruction by the user. Scroll. Here, the scrolling instruction by the remote commander 40 is, for example, operation of a joystick provided in the remote commander 40, operation of a pressing operator for instructing a scroll direction, or the like. In addition, in the scroll instruction by the operation of the touch panel 39, in the direction to be displayed by scrolling, the operation of touching the position displaced from the center of the display screen only during the scrolling time with the finger, the direction to be displayed by scrolling, For example, the user touches the touch panel 39 only during the scrolling time after sliding the finger touched from the center of the screen.

  On the other hand, when the user gives an instruction to switch the scale of the map display, the scale of the map display is sequentially switched in response to the instruction from the user. Here, the scale switch instruction by the remote commander 40 is, for example, operation of a wide-area, detailed operator provided in the remote commander 40. The scale switching instruction by the operation of the touch panel 39 is an operation of selecting a scale from this menu after displaying a menu for instructing the scale of map display.

  As a result, the car navigation apparatus 1 can ensure the same usability as the conventional car navigation apparatus.

  Further, when a temporary zoom instruction is obtained by the user, the controller 33 continuously reduces the map display scale by using the temporary zoom instruction as a trigger by executing the processing procedure shown in FIGS. After zooming out the display, after a certain amount of time has passed, the map display is zoomed in to the original scale. At this time, when scrolling is instructed by the user, the zoom-out is ended or the zoom-in is temporarily stopped, the map display is scrolled, and then the original scale is zoomed in.

  Here, for such temporary zoom instructions, pressing operation of a dedicated operator provided in the remote commander 40, temporary contact of a predetermined area of the touch panel 39, input of a locus of a predetermined shape by the touch panel 39, etc. Can be applied.

  That is, when starting this processing procedure, the controller 33 proceeds from step SP1 to step SP2, where it is determined whether or not the instruction by the user is a temporary scroll instruction, and if a negative result is obtained here, step SP2 to step SP3. Then, the procedure ends. On the other hand, if an affirmative result is obtained in step SP2, the controller 33 proceeds from step SP2 to step SP4, where the scale of the map display is reduced at a constant rate of change and the map display is zoomed out. In subsequent step SP5, it is determined whether or not scrolling is instructed by the user. If a negative result is obtained here, the process proceeds to step SP6. Here, the controller 33 determines whether or not the current zoom-out scale is a preset limit value. If a negative result is obtained here, the process returns from step SP6 to step SP4. Thus, once the temporary zoom instruction is obtained by the user, the controller 33 repeats the processing procedure of steps SP4-SP5-SP6-SP4 unless the user instructs scrolling, and the scale of the map display becomes the limit value. Until the map display is zoomed out by gradually reducing the scale of the map display.

  It should be noted that the limit value related to the determination in step SP6 is the scale value of the map display when zoomed out to the maximum by the user's prior settings, the program settings related to this series of processes, and the like. The 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 zoom out, in addition to the case where the scale value is simply set.

  Further, when the zoom-out is performed in this manner and the scale of the map display becomes the limit value, the controller 33 moves from step SP6 to step SP7 by obtaining a positive result in step SP6, and starts the built-in timer. Measurement is started, and in the subsequent step SP8, it is determined whether or not scrolling is instructed by the user. If a negative result is obtained here, the controller 33 proceeds to step SP9 and determines whether or not a fixed time has elapsed by the timer that started time measurement in step SP7. If a negative result is obtained here, the controller 33 returns to step SP8. When the zoom-out is performed and the scale of the map display becomes the limit value, the controller 33 repeats the processing procedure of steps SP8-SP9-SP8 unless the user gives an instruction to scroll, stops the zoom-out, and elapses for a certain period of time. Wait.

  Further, when a certain time elapses in this way and an affirmative result is obtained in step SP9, the controller 33 moves from step SP9 to step SP10, where the scale of the map display is increased by a certain rate of change, Zoom in on the map display. In subsequent step SP11, it is determined whether or not scrolling is instructed by the user. If a negative result is obtained here, the process proceeds to step SP12. Here, the controller 33 determines whether or not the current scale of the map display is the original scale, and if a negative result is obtained here, the process returns from step SP12 to step SP10. As a result, the controller 33 zooms out the map display to the scale of the limit value and then repeats the processing procedure of steps SP10-SP11-SP12-SP10 after a certain time has elapsed until the scale of the map display becomes the original scale. The map display is zoomed in by gradually increasing the scale of the map display.

  Further, when the zoom-in is performed in this way and the scale of the map display becomes the original scale, an affirmative result is obtained in step SP12, so that the process proceeds from step SP12 to step SP3, and this processing procedure is ended.

  As a result, the controller 33 zooms out the map display to the limit value according to the temporary zoom instruction, as indicated by the reference symbol LL1 in FIG. Zoom in on the map display. In this series of processing, the controller 33 allows a change in the image due to zoom-out and zoom-in to be seen smoothly. Also, zoom-out and zoom-in processing is performed so that the scale changes linearly, that is, the scale is expressed by a linear function with time set as a variable. Don't feel it.

  On the other hand, when scrolling is instructed by the user during zooming out in this way, the controller 33 shifts from step SP5 to step SP13 because a positive result is obtained in step SP5. Thereby, after completing the zoom-out, the controller 33 scrolls the map display in response to an instruction from the user, and proceeds to step SP10.

  Accordingly, as shown by reference numeral LL2 in FIG. 6 in comparison with FIG. 5, the controller 33 stops the zoom-out when the user instructs scrolling at the time t1 during zoom-out, and responds to the user's instruction. When the map display is scrolled and the user's scrolling instruction ends at time t2, the map display is zoomed in to the original scale.

  Further, when scrolling is instructed while zoomed out and displayed with the limit value, the controller 33 scrolls the map display according to the user's instruction, and then returns to the original scale by the end of the scrolling instruction by the user. Zoom in on the map display.

  On the other hand, when scrolling is instructed by the user when zooming in to the original scale, the controller 33 moves from step SP11 to step SP14 by obtaining an affirmative result in step SP11. The map display is scrolled in response to, and then the process proceeds to step SP12.

  Accordingly, as shown by reference numeral LL3 in FIG. 7 in contrast to FIG. 5, the controller 33 temporarily stops zooming in when zooming in is instructed by the user at time t1 during zooming in, and displays the map display according to the user's instruction. When scrolling is completed and the user's scrolling instruction is completed at time t2, the canceled zoom-in is resumed and the map is displayed at the original scale.

  As a result, in this car navigation device 1, the map display is zoomed out to the limit value in response to a temporary zoom instruction so as to roughly indicate the change in the area of the map display displayed by the display unit 37 with reference numerals L1 to L5 in FIG. Then, the map display is zoomed in to the original scale after a certain period of time.

  Here, FIGS. 9A and 9B are display screens of the display unit 37 shown in comparison with FIG. 8, and FIG. 9A shows map displays before and after such temporary zoom processing. FIG. 9B is a plan view showing a state in which the zoom-out is performed to the limit value by the temporary zoom process. In these map displays, the controller 33 displays a mark indicating the area displayed at the original scale on the map. Specifically, in this embodiment, when the scale with respect to the original scale is equal to or smaller than a predetermined value, as shown in FIG. 9B, it is displayed by surroundings showing the four corners of the area displayed at the original scale. When this scale is further reduced, the area displayed at the original scale is displayed by rectangular hatching, and when the scale is further reduced, the area displayed at the original scale is displayed. The position is displayed by a cursor with line segments extending in the horizontal and vertical directions.

  The controller 33 also forms a display showing the map scale corresponding to each scale on the display screen of the display unit 37. In the example of FIGS. 9A and 9B, this display is displayed by the distance in the map display.

(2) Operation of the embodiment In the above configuration, in the car navigation device 1 (FIGS. 2 and 3), a map is displayed on the display unit 37 in accordance with an instruction from the user, and the map is used to guide the user to the destination. invite. As a result, the user can confirm the current position by performing a display scale switching operation on the display of the map, and further scroll the map display to check the surrounding geography. You will discover the facility. In some cases, the map display scale switching and scrolling operations are repeated to search for the target facility, and further, the destination is set.

  With regard to such an operation, in the car navigation device 1, when the user instructs temporary zooming by operating the touch panel 39 and the remote commander 40, the scale of the map display is continuously controlled by the control of the controller 33 using this instruction as a trigger. After the map display is zoomed out after the reduction, the map display zooms in to the original scale after a certain period of time has passed (FIGS. 1, 4, 5, and 8).

  As a result, in this car navigation device 1, for example, when confirming the peripheral facility at the current position, a large area is temporarily displayed on the map by zooming out by a simple operation of simply instructing temporary zooming. In this way, the user can confirm the surrounding facilities by a simple operation. In addition, since such zoom-out is a temporary display, the user can return to the original map display and receive a navigation instruction by the map display, for example, without returning the map display to the original scale. Thus, after confirming the surrounding facilities by a simple operation, it is possible to continuously receive various information provided by the car navigation device 1 until then.

  Thus, when the user zooms out temporarily and confirms the target facility in this way, the user may want to check the periphery of the target facility in detail.

  For this reason, in the car navigation apparatus 1, when scrolling is instructed by the user in the processing related to the temporary zoom, zoom-out and zoom-in are stopped, and the map display is scrolled according to the user's instruction. Zoom in to scale (FIGS. 6 and 7). As a result, during zoom-out with this temporary zoom, the user can make the target location approximately at the center of the display screen during the period of display at a certain scale after zoom-out and further during zoom-in. In addition, by simply scrolling the map display, the surrounding map of the target facility or the like can be confirmed in detail.

  As a result, the car navigation apparatus 1 can confirm facilities and the like in the peripheral area of the displayed area by a simple operation.

  In these processes, if the user instructs scrolling during zoom-out in this temporary zoom, it is considered that the user has found a destination and instructed scrolling during zoom-out. When the scrolling is finished, the map display is zoomed in to the original scale (FIG. 6).

  Thus, in this case, the time required for the temporary zoom process can be shortened as much as possible, and a detailed map of a location desired by the user can be displayed, and the usability can be improved accordingly.

  On the other hand, when scrolling is instructed by the user during a period of display at a certain scale after zooming out, the map display is not performed until the end of the scrolling. Zoom in to the original scale.

  As a result, in this case as well, the time required for the temporary zoom process can be shortened as much as possible to display a detailed map of a location desired by the user, and the usability can be improved accordingly.

  On the other hand, when scrolling is instructed by the user during zooming in, the scrolling process is executed by temporarily canceling zooming in, and then the scale of the map display is restored by resuming the canceling zooming in. As a result, the user once displayed the destination approximately at the center of the screen by scrolling, but if the destination jumps out of the screen due to zoom-in, or if it is about to jump out, the display is scrolled again to The location and the like can be confirmed on a detailed map, and this also improves the user-friendliness.

(3) Advantages of the embodiment According to the above configuration, the user's instruction is used as a trigger, the display is temporarily zoomed out and displayed in the original size, and the user scrolls between these processes. By accepting the operation, it is possible to confirm the facilities and the like existing in the peripheral area of the display area by a simple operation.

  In addition, if the scrolling is not instructed by the input means after the zoom-out is started in this way until the zoom-in is finished, the zoom-out is stopped when the display size of the display means becomes the limit value due to the zoom-out. After waiting for a certain period of time, zoom in to the original size, and when checking the vicinity of the current position, the user can check the surrounding area by a simple operation that simply gives a trigger. This can improve usability.

  In addition, when scrolling is instructed by the input means after the zoom out is started and before the display size reaches the limit value, the zoom is temporarily zoomed in by zooming in to the original size at the end of scrolling. It is possible to display the detailed map of the part desired by the user by shortening the time to be used as much as possible, and to improve the usability accordingly.

  Further, when scrolling is instructed by the input unit for a certain time after the display size of the display unit reaches the limit value, the display unit zooms in to the original size when the scrolling is finished. This also makes it possible to shorten the time for temporary zoom-out as much as possible and display a detailed map of a user-desired location, thereby improving usability accordingly.

  In addition, since the display target for such scrolling is a map, it can be applied to the display of a map, and further applied to a car navigation device, thereby improving usability.

  The car navigation apparatus according to this embodiment is configured such that in the configuration described above with reference to FIGS. 2 and 3, the start of zoom-in in the temporary zoom process can be instructed by operating the remote commander 40 and the touch panel 39. The car navigation device according to this embodiment is configured in the same manner as the car navigation device 1 according to the first embodiment except that the configuration related to zoom-in at the time of the temporary zoom is different. The configuration shown in FIGS. 2 and 3 will be described as appropriate.

  For this reason, in the controller 33 of the car navigation device 1 according to this embodiment, in the same manner as described above with respect to the first embodiment, after the zoom-out is started using the temporary zoom instruction as a trigger, the display scale becomes the limit value. Then, the zoom out is finished. In addition, when the zoom-in is completed in this way, or when zoom-in is finished and the map is displayed at the scale based on the limit value, the user is instructed to zoom in on the temporary zoom. And zoom in the map display to the original scale.

  When scrolling is instructed by the user during these temporary zooms, the controller 33 executes the scrolling process in the same manner as described above for the first embodiment. In this case, when scrolling is instructed by the user while zooming out and displaying at a scale of the limit value, zooming in is performed in the same manner as in the first embodiment without waiting for the user's instruction at the end of scrolling. Return the map display to its original scale.

  In this embodiment, by starting the zoom-in with an instruction from the user in the temporary zoom as a trigger, the user's intention is reflected in the zoom-in process, and for example, a process such as searching around the current position for a long time is performed. It can be executed, and this can also improve usability.

  At this time, when zooming out, if scrolling is instructed by the input means while the scale is displayed with the limit value, the display means zooms in to the original size when the scrolling ends. By doing so, the time for temporary zoom-out can be shortened as much as possible, and a detailed map of a user's desired location can be displayed, and the usability can be improved accordingly.

  In this embodiment, as shown in FIG. 10, in the configuration according to the first embodiment, the user is again instructed to perform temporary zoom when zooming out by temporary zoom processing, displaying for a certain period of time using limit values, and zooming in. Then, the map display is zoomed out again to a scale with a limit value based on the scale currently being displayed, and after a certain time has passed, the original scale is zoomed in. In the example shown in FIG. 10, a temporary zoom is instructed again by the user when zooming in.

  Thus, in this embodiment, by repeatedly inputting a trigger relating to temporary zoom as necessary, it is possible to zoom out to a desired scale and confirm a map, and thus a desired destination cannot be detected. In some cases, such an operation can be repeated to improve user convenience.

  In the above-described embodiment, the case where the zoom-out is limited by the limit value has been described. However, the present invention is not limited to this, and such a limit may not be provided.

  Further, in the above-described embodiment, the case where the scale change is linear, that is, the scale at the time of zooming out and zooming in by a linear function in which time is set as a variable has been described. Not limited to this, when a quadratic function, an exponential function, or the like is used instead of the temporary function, various changes can be made as needed for zooming out and changing the scale during zooming in. Instead of the scale for display, the time may be set as a variable to express the size of the area to be displayed, and the change in scale during zoom-out or zoom-in may be set.

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

  In the above-described embodiments, the case where the present invention is applied to the display of a map in a car navigation apparatus has been described. However, the present invention is not limited to this, and the map display in various apparatuses such as a map display in a personal computer or the like is used. Can be widely applied to. In addition to the case where such a map is to be displayed, various design drawings such as wiring pattern diagrams, various photographs such as aerial photographs, and further displays that move the viewpoint of a three-dimensional structure or a three-dimensional object. Can be widely applied.

  The present invention relates to a display device, a display method, a display program, and a recording medium recording the display program, and can be applied to, for example, a car navigation device.
