[Touch scroll processing]
Next, a map image corresponding to a coordinate position where a function icon such as a destination icon 55 on the display screen of the liquid crystal display 15 is pressed, which is a process executed by the CPU 41 of the navigation device 1 configured as described above. The “touch scroll process” for scrolling will be described with reference to FIGS. 2 is executed by the CPU 41 at predetermined time intervals (for example, every 10 milliseconds).

  As shown in FIG. 2, first, in step (hereinafter abbreviated as “S”) 11, when the user inputs a destination facility address, telephone number, or the like via the operation unit 14, The map information around the facility is read from the navigation map information 26 and displayed on the liquid crystal display 15.

Here, an example in which the map image is displayed on the liquid crystal display 15 will be described with reference to FIG.
As shown in FIG. 3, the CPU 41 displays a facility icon 52 indicating the location of the facility as the destination in the center of the screen of the liquid crystal display 15 and displays a map image around the facility. Further, the CPU 41 displays addresses in the vicinity where the facility is located in an address display column 51 provided at the upper edge of the screen. Further, the CPU 41 displays a memory point icon 54 and a destination icon 55 in a function icon column 53 provided at the lower right of the screen. Further, the CPU 41 sets a scroll area 56 having a predetermined width (for example, a width of about 10 mm) over the entire periphery of the peripheral portion of the display screen in a substantially rectangular frame shape.

  Predetermined functions are assigned to the icons 53 and 54 displayed in the function icon column 53, respectively. When the icons 53 and 54 are selected by the user and moved on the screen, the positions after the movement are displayed. Perform the function assigned in. For example, the memory point icon 54 is assigned a function of storing the moved position as a memory point in the map information DB 25, and the position stored in the map information DB 25 as a memory point easily reads the map information or the like. It is set so that it can be put out.

  The destination icon 55 is assigned a function for setting the moved position as the destination, and the route search to the position set as the destination by the CPU 41 is performed. For example, as shown in FIG. 4, when the user moves the destination icon 55 onto the facility icon 52 and releases the index finger 61 from the touch panel 18, the facility indicated by the facility icon 52 is set as the destination. Route search to the facility is performed.

  Subsequently, as shown in FIG. 2, in S <b> 12, the CPU 41 executes a determination process for determining whether the memory point icon 54 or the destination icon 55 is selected. That is, the CPU 41 executes a determination process for determining whether or not the first pressed position on the touch panel 18 is a position where the memory point icon 54 or the destination icon 55 is displayed.

  Then, when it is determined that the memory point icon 54 or the destination icon 55 is not selected, that is, it is determined that the first pressed position on the touch panel 18 is not the display position of the memory point icon 54 or the destination icon 55. In this case (S12: NO), the CPU 41 ends the process.

  On the other hand, when it is determined that the memory point icon 54 or the destination icon 55 has been selected, that is, when the first pressed position on the touch panel 18 is determined to be the display position of the memory point icon 54 or the destination icon 55. (S12: YES), the CPU 41 proceeds to the process of S13. In S <b> 13, the CPU 41 executes determination processing for determining whether or not the selected memory point icon 54 or destination icon 55 is displayed in the scroll area 56.

  If it is determined that the selected memory point icon 54 or destination icon 55 is not displayed in the scroll area 56 (S13: NO), the CPU 41 proceeds to the process of S14. In S <b> 14, the CPU 41 determines whether or not the selection of the memory point icon 54 or the destination icon 55 has been released, that is, whether or not the user's finger has left the touch panel 18 and the touch panel 18 has not been pressed. Execute the process.

When the selection of the memory point icon 54 or the destination icon 55 is canceled, that is, when it is determined that the user's finger has left the touch panel 18 and the touch panel 18 has not been pressed (S14: YES), the CPU 41 The process ends.
On the other hand, if it is determined that the selection of the memory point icon 54 or the destination icon 55 has not been released, that is, the touch panel 18 has been pressed (S14: NO), the CPU 41 proceeds to the process of S15.

  In S <b> 15, the CPU 41 moves and displays the memory point icon 54 or the destination icon 55 selected by the user following the pressed position of the touch panel 18. Accordingly, when the user moves the memory point icon 54 or the destination icon 55 while pressing the memory point icon 54 or the destination icon 55, the user can drag the pressed memory point icon 54 or the destination icon 55.

  In this embodiment, the processing is performed using the display position of the memory point icon 54 or the destination icon 55 as the icon position. However, the operation of the icon is performed while the memory point icon 54 or the destination icon 55 is pressed. If it is performed, the process may be performed with the position pressed by the user as the position of each icon. For example, when the user presses the memory point icon 54 or the destination icon 55 with a finger, the pressed icon is hidden under the finger, so that the icon may be displayed while being shifted from the pressed position. In this case, operability is improved by performing processing with the position pressed by the user as the position of each icon.

Subsequently, in S <b> 16, the CPU 41 executes a determination process for determining whether or not the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed in the scroll area 56.
If it is determined that the memory point icon 54 or the destination icon 55 selected by the user is not moved and displayed in the scroll area 56 (S16: NO), the CPU 41 executes the processes after S14 again. .

On the other hand, if it is determined that the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed in the scroll area 56 (S16: YES), the CPU 41 proceeds to the process of S17.
In S17, the CPU 41 moves the map image by a predetermined distance in the direction in which the position on the map where the memory point icon 54 or the destination icon 55 selected by the user in the scroll area 56 is displayed moves to the center of the display screen. (For example, the distance is about 5 mm.) After scrolling, the processing after S14 is executed again.

  For example, as shown in FIGS. 4 and 5, the user presses the destination icon 55 with the index finger 61 and moves it to the facility icon 52, and further moves it directly below to move it into the scroll area 56. When the location icon 55 is continuously pressed, the map image is scrolled in the direction in which the position on the map where the destination icon 55 is displayed moves to the center of the display screen (the direction of the arrow 62) ( Scroll straight ahead).

  Then, as shown in FIG. 6, when the user releases the index finger 61 from the destination icon 55, that is, when the index finger 61 is released from the touch panel 18, scrolling of the map image is stopped, and the desired destination is displayed on the display screen. Is displayed. 4 to 6, the destination icon 55 is moved and displayed by pressing the index finger 61, but the same applies when the memory point icon 54 is pressed and moved.

  On the other hand, as shown in FIG. 2, when it is determined that the memory point icon 54 or the destination icon 55 selected in S13 is displayed in the scroll area 56 (S13: YES), the CPU 41 proceeds to S18. Transition to processing. In S <b> 18, the CPU 41 determines whether or not the selection of the memory point icon 54 or the destination icon 55 has been released, that is, whether or not the user's finger has left the touch panel 18 and the touch panel 18 has not been pressed. Execute the process.

When it is determined that the selection of the memory point icon 54 or the destination icon 55 has been released, that is, the user's finger has left the touch panel 18 and the touch panel 18 has not been pressed (S18: YES), the CPU 41 Ends the processing.
On the other hand, when it is determined that the selection of the memory point icon 54 or the destination icon 55 has not been released, that is, the touch panel 18 has been pressed (S18: NO), the CPU 41 proceeds to the process of S19.

  In S <b> 19, the CPU 41 moves and displays only the memory point icon 54 or the destination icon 55 selected by the user following the pressed position of the touch panel 18 without scrolling the map image. That is, when the first pressed position of the memory point icon 54 or the destination icon 55 is within the scroll area 56, the CPU 41 suppresses the scrolling of the map image.

  Subsequently, in S <b> 20, the CPU 41 executes a determination process for determining whether the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed outside the scroll area 56. That is, the CPU 41 executes determination processing for determining whether or not the pressed position of the touch panel 18 has moved into an area inside the scroll area 56 of the display screen.

  When it is determined that the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed outside the scroll area 56 (S20: YES), the CPU 41 executes the processes after S14.

  For example, as shown in FIGS. 6 and 7, when the user presses the destination icon 55 displayed in the scroll area 56 with the index finger 61, the CPU 41 suppresses the scrolling of the map image, and then the scroll area 56. When the destination icon 55 is moved and displayed outside, the destination icon 55 is moved and displayed, and then the processes of S14 to S17 are executed. Accordingly, when the user moves the destination icon 55 into the scroll area 56 again, the map image is scrolled in a direction in which the position on the map where the destination icon 55 is displayed moves to the center of the display screen. Is done.

  On the other hand, when it is determined that the memory point icon 54 or the destination icon 55 selected by the user is not moved and displayed outside the scroll area 56, that is, it is determined that the pressed position of the touch panel 18 is within the scroll area 56. When it does (S20: NO), CPU41 transfers to the process of S21.

  In S <b> 21, the CPU 41 determines whether or not the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed within the scroll area 56 by a predetermined distance (for example, about 1 cm or more). Execute the process. That is, the CPU 41 executes determination processing for determining whether or not the pressed position of the touch panel 18 has moved within the scroll region 56 by a predetermined distance or more from the position where the touch panel 18 is first pressed.

  When it is determined that the memory point icon 54 or the destination icon 55 selected by the user has been moved and displayed within the scroll area 56 by a predetermined distance or more (S21: YES), the CPU 41 executes the processes after S14. To do.

  For example, as shown in FIGS. 6 and 8, when the user presses the destination icon 55 displayed in the scroll area 56 with the index finger 61, the CPU 41 suppresses the scrolling of the map image, and then the scroll area 56. When the inside is moved a predetermined distance or more (for example, about 2 cm or more), the destination icon 55 is moved and displayed, and then the processes of S14 to S17 are executed.

  Therefore, when the user moves and displays the destination icon 55 within the scroll area 56 by a predetermined distance and continues to press the destination icon 55, the position on the map where the destination icon 55 is displayed is displayed. The map image is scrolled in the direction of moving to the center of the screen (the direction of arrow 63). Then, when the user releases the index finger 61 from the destination icon 55, that is, when the index finger 61 is released from the touch panel 18, scrolling of the map image is stopped, and a desired destination is displayed in the display screen.

  On the other hand, as shown in FIG. 2, when it is determined that the memory point icon 54 or the destination icon 55 selected by the user has not been moved and displayed within the scroll area 56, that is, the pressed position of the touch panel 18. If the CPU 41 determines that it has not moved within the scroll area 56 by a predetermined distance or more from the position where it is first pressed (S21: NO), the CPU 41 proceeds to the process of S22.

In S <b> 22, the CPU 41 determines whether or not the memory point icon 54 or the destination icon 55 selected by the user has been continuously pressed in the scroll area 56 for a predetermined time or longer (for example, about 5 seconds or longer). A determination process for determining is executed.
When it is determined that the memory point icon 54 or the destination icon 55 selected by the user has been continuously pressed for a predetermined time or longer in the scroll area 56 (S22: YES), the CPU 41 performs the processes after S14. Execute.

  For example, as shown in FIGS. 6 and 9, when the user presses the destination icon 55 displayed in the scroll area 56 with the index finger 61, the CPU 41 suppresses scrolling of the map image, and then When the ground icon 55 is continuously pressed for a predetermined time or longer (for example, about 5 seconds or longer), the processing of S14 to S17 is executed.

  Accordingly, when the user presses the destination icon 55 within the scroll area 56 for a predetermined time or longer, the position on the map where the destination icon 55 is displayed moves to the center of the display screen (in the direction of the arrow 64). The map image is scrolled to. Then, when the user releases the index finger 61 from the destination icon 55, that is, when the index finger 61 is released from the touch panel 18, scrolling of the map image is stopped, and a desired destination is displayed in the display screen. 7 to 9, the destination icon 55 is moved and displayed by pressing the index finger 61. However, the same applies when the memory point icon 54 is pressed and moved.

  On the other hand, as shown in FIG. 2, when it is determined that the memory point icon 54 or the destination icon 55 selected by the user has not been pressed continuously for a predetermined time or longer in the scroll area 56 (S22: NO). ), The CPU 41 executes the processing after S18 again. For example, the display state of the liquid crystal display 15 shown in FIG. 6 is continued.

  As described above in detail, in the navigation device 1 according to the present embodiment, the CPU 41 displays the memory point icon 54 and the destination icon 55 together with the map image in the function icon column 53 provided at the lower right of the screen of the liquid crystal display 15. To do. Further, the CPU 41 sets a scroll area 56 having a predetermined width in a substantially rectangular frame shape over the entire periphery of the peripheral portion of the display screen. The user can drag the pressed memory point icon 54 or the destination icon 55 by moving either the memory point icon 54 or the destination icon 55 in a pressed state.

  In addition, the user first presses the memory point icon 54 or the destination icon 55 in an area outside the scroll area 56 set at the peripheral portion of the display screen, and then continuously drags and presses it in the scroll area 56. In this case, the map image can be scrolled so as to move the currently pressed point to the center of the display screen.

  When the display position when the memory point icon 54 or the destination icon 55 is first pressed is in the scroll area 56, the CPU 41 displays the memory point icon 54 or the destination icon displayed in the scroll area 56. When 55 is pressed, the scrolling of the map image is suppressed. Thus, even if the user presses the memory point icon 54 or the destination icon 55 displayed in the scroll area 56, the map image is not scrolled, so the pressed memory point icon 54 or the destination icon 55 is currently displayed. It can be moved smoothly by dragging to a point in the map image.

  When the display position when the memory point icon 54 or the destination icon 55 is first pressed is in the scroll area 56, the user places the pressed memory point icon 54 or the destination icon 55 in the scroll area 56. After dragging more than a predetermined distance, the map image is scrolled so that the currently pressed point moves to the center of the display screen by continuing the pressing. As a result, the user drags the memory point icon 54 or the destination icon 55 in the scroll area 56 more than a predetermined distance in the scroll area 56 and then continues to press the map image to quickly scroll the map image toward the center of the display screen. Thus, the desired point can be easily displayed.

  In addition, the user drags the memory point icon 54 or the destination icon 55 displayed in the scroll area 56 to the outside of the scroll area 56, and then drags again into the scroll area 56 and then continuously presses it. The map image can be scrolled so that the currently pressed point moves to the center of the display screen. As a result, the user drags the memory point icon 54 or the destination icon 55 to an arbitrary position within the scroll area 56 set at the peripheral edge of the display screen, and scrolls the map image to easily find a desired point. Can be displayed.

  In addition, when the user continuously presses the memory point icon 54 or the destination icon 55 displayed in the scroll area 56 for a predetermined time or more, the currently pressed point moves to the center of the display screen. A desired point can be easily displayed by scrolling the map image.

  In addition, this invention is not limited to the said Example, Of course, various improvement and deformation | transformation are possible within the range which does not deviate from the summary of this invention.

  For example, when the scroll area 56 is set over the entire screen edge of the display screen, and the memory point icon 54 or the destination icon 55 is in contact with the screen edge of the display screen in S13, S16, and S20 to S22. In addition, it may be determined that the icons 54 and 55 are located in the scroll area 56. Accordingly, the user can scroll the map image by dragging the icons 54 and 55 so as to contact the screen edge of the display screen.
