The touch panel 18 sends a signal corresponding to the operation position on the touch panel 18 to the touch panel control unit 19, and the touch panel control unit 19 calculates the pressed position of the touch panel 18.

  The control circuit 11 includes a microprocessor and its peripheral circuits, and performs various controls by executing a control program stored in the ROM 12 using the RAM 13 as a work area. When the control circuit 11 performs a predetermined route search process based on the map data stored in the DVD-ROM 112, the processing result is displayed on the display monitor 16 as a recommended route.

  The current location detection device 14 is a device that detects the current location of the vehicle. For example, a vibration gyro 14a that detects the traveling direction of the vehicle, a vehicle speed sensor 14b that detects the vehicle speed, and a GPS signal from a GPS (Global Positioning System) satellite. GPS sensor 14c and the like. 1 A of navigation apparatuses determine the display range of a map, a route search start point, etc. based on the present location of the vehicle detected by this present location detection apparatus 14, and display the present location on a map.

  The image memory 15 stores image data to be displayed on the display monitor 16. This image data includes road map drawing data and various graphic data, which are appropriately generated based on map data stored in the DVD-ROM 112 read by the disk drive 111. The navigation device 1A performs map display and the like by using the image data generated in this way.

  The disk drive 111 reads map data for displaying a map on the display monitor 16 from the loaded DVD-ROM 112. The map data includes map display data, route search data, and the like. These data include road link information and node information. The map display data has map data of a plurality of scales from wide areas to details, and the scale of the display map can be changed according to a user request. The map data may be read from a recording medium other than the DVD-ROM 112, such as a CD-ROM or a hard disk.

  The display monitor 16 provides the user with various information such as a road map near the vehicle position as a screen display based on various information such as map data. The input device 17 has an input switch for the user to set various commands, and is realized by a remote controller or the like. The user manually operates the input device 17 according to an instruction on the display screen of the display monitor 16 to select a destination and set the destination. Further, the road map displayed on the display monitor 16 can be scrolled by operating the input device 17.

  As described above, the touch panel 18 is a transparent panel provided on the monitor screen of the display monitor 16. The display screen displayed on the display monitor 16 is displayed through the touch panel 18, and when the display screen of the display monitor 16 is pressed, the touch panel 18 is pressed. The touch panel 18 has an input function like the input device 17.

Further, by pressing the touch panel 18, a destination can be set on the road map, the road map can be scrolled, and a range to be displayed as a fixed image to be described later can be designated.

  When the destination is set by the user, the navigation apparatus 1A calculates a route to the destination based on a predetermined algorithm, using the current location detected by the GPS sensor 14c as a departure location. The route thus obtained (hereinafter referred to as a recommended route) is displayed separately from other roads by changing the display form, for example, the display color. Thereby, the user can recognize the recommended route on the map. In addition, the navigation device 1A instructs the user to travel in the direction of the screen or voice so that the vehicle can travel according to the recommended route, thereby guiding the route of the vehicle.

  The data storage unit 110 is configured by a rewritable recording medium such as a flash memory or a hard disk, and stores data necessary for the function of the navigation device 1A. Information stored in the data storage unit 110 is appropriately read and used by the control circuit 11. Further, the image data of the road map whose range is designated is stored.

  Next, a display operation of a fixed image of a road map in the navigation device 1A of the first embodiment will be described with reference to FIGS. It is assumed that the user is displaying the road map 20 on the display monitor 16 as shown in FIG. On the road map 20, a vehicle position mark 21 indicating the current location of the vehicle is displayed. Here, it is assumed that the user is going to examine the state of the position slightly outside the display range of the display monitor 16. Further, it is assumed that the host vehicle position mark 21 is desired to be displayed at the same time so that the positional relationship with the vehicle can be grasped.

  In order to examine the state of the position slightly outside the display range of the display monitor 16, the road map 20 may be scrolled. However, when the road map 20 is scrolled, the vehicle position mark 21 may slightly deviate from the display screen of the display monitor 16 and become invisible. In such a case, there is a method in which the scale of the road map 20 is reduced and the vehicle position mark 21 and a position away from the current location are displayed simultaneously. However, if the scale ratio of the road map 20 is reduced, detailed information on the road map 20 cannot be understood.

  Therefore, in order to enable the user to grasp the positional relationship with the vehicle even if the road map 20 is scrolled, the road map around the vehicle position mark 21 is fixed so that it does not come off the display screen even if the user scrolls. To do. In the embodiment of the present invention, a range of a road map to be fixed, that is, a range of a road map to be displayed as a fixed image is specified by drawing a frame on the road map 20 displayed on the display monitor 16 by a pressing operation.

  When the YES button 31 is pressed, the range within the frame 33 is displayed as a fixed image 41 as shown in FIG. The position and size of the fixed image 41 are the same as the range in the frame 33. A fixed release button 42 is displayed together with the fixed image 41 on the display screen. When the fixing release button 42 is pressed, the fixed image 41 is deleted.

  FIG. 5 shows a scroll of the road map 20 of FIG. 4 in the direction of the arrow. As shown in FIG. 5, the position of the fixed image 41 does not change even if the road map 20 is scrolled. Therefore, even if the vehicle position mark 21 deviates from the display screen by scrolling the road map 20, the fixed vehicle image 41 displaying the vehicle position mark 21 is referred to and the vehicle position mark 21 deviated from the display screen is displayed. The position can be recognized, and the positional relationship between the vehicle and the newly displayed road map can be grasped.

  When the NO button 32 in FIG. 3 is pressed, the frame 33 is deleted. Then, it is possible to redo the specification of the range of the road map displayed as a fixed image.

  Next, the fixed image display process will be described with reference to the flowchart of FIG. The processing in FIG. 6 is executed in the control circuit 11 by a program that starts when the mode is switched to the fixed scroll mode. Here, the fixed scroll mode is a mode in which a predetermined range of the road map can be displayed as a fixed image, and is switched by pressing a fixed scroll button (not shown).

  In step S601, it is determined whether the line 22 drawn by pressing on the touch panel 18 is closed. Here, when the overlap of the lines 22 is detected, it is determined that the lines 22 are closed. If the line 22 is closed, an affirmative determination is made in step S601 and the process proceeds to step S602. If it is not closed, step S601 is repeated. In step S602, the range designation screen 30 is displayed.

  In step S603, it is determined whether the YES button 31 has been pressed. If the button is pressed, an affirmative determination is made in step S603 and the process proceeds to step S604. If the YES button 31 is not pressed, a negative determination is made in step S603, and the process proceeds to step S608. In step S604, the image data of the road map in the range surrounded by the line 22 (frame 33) is stored in the data storage unit 110 as a fixed image together with the display position. In step S605, the fixed image is displayed overlaid on the image generated from the map data, that is, the image of the scrollable road map, at the display position stored at the same time as the line 22 is erased.

  In step S606, it is determined whether the fixation release button 42 has been pressed. If it is pressed, an affirmative determination is made in step S606, and the process proceeds to step S607. If not pressed, the process returns to step S605. In step S607, the fixed image 41 is deleted. Then, the fixed image display process ends.

  In step S608, it is determined whether the NO button 32 has been pressed. If the button is pressed, an affirmative determination is made in step S608, and the process proceeds to step S609. If it is not pressed, step S608 is denied and the process returns to step S603. In step S609, the line 22 is erased. Then, the process returns to step S601.
