[2.1. Switching control from bird's-eye view image to plane image]
First, a case where an image displayed on the display 214c is switched from a bird's-eye view image to a planar image will be described with reference to FIGS. FIG. 3 is a diagram illustrating an example of image transition when switching from a bird's-eye view image to a plane image, and FIG. 4 is a diagram illustrating a transition example of a viewpoint position when drawing a vehicle mark when switching from a bird's-eye view image to a plane image. FIG.

  FIG. 3A is a diagram illustrating an example of an overhead image 300A, and FIG. 3H is a diagram illustrating an example of a planar image 300H. FIGS. 3B to 3G show intermediate images 300B, 300C, 300D, 300E, 300F, 300G (hereinafter, referred to as the intermediate images 300B, 300B, 300C, 300D, and 300E) displayed when the image is switched from the overhead image 300A to the planar image 300H. FIG. 10 is a diagram illustrating an example of “intermediate images 300B to 300G”.

  The bird's-eye view image 300A and the plane image 300H are route guidance images for guiding the user to the route to the destination, and include a vehicle mark 301A and a vehicle mark 301H, respectively, indicating the vehicle on which the in-vehicle device 200 is mounted. The route 302A and the route 302H are displayed.

  In this embodiment, the user can select a display mode when the route guidance image is displayed on the display 214c from two display modes. The display mode includes a bird's-eye view mode and a plane mode. The control unit 211 displays the bird's-eye view image 300A when the bird's-eye view mode is selected, and displays the plane image 300H when the plane mode is selected. . The bird's-eye view image 300A is an image depicting the vehicle mark 301A and its surroundings from behind and above the vehicle mark 301A, while the plane image 300H is a vehicle mark from directly above the vehicle mark 301H. An image depicting 301H and its surroundings, each having a different display format.

  When the user switches the display mode from the bird's-eye view mode to the plane mode, the control unit 211 switches the image from the bird's-eye view image 300A to the plane image 300H. At this time, the control unit 211 does not immediately switch the image from the overhead image 300A to the planar image 300H, but switches the image in the order of the overhead image 300A, the intermediate images 300B, 300C, 300D, 300E, 300F, 300G, and the planar image 300H. To display.

  The intermediate images 300B, 300C, 300D, 300E, 300F, and 300G respectively display the own vehicle marks 301B, 301C, 301D, 301E, 301F, and 301G and the routes 302B, 302C, 302D, 302E, 302F, and 302G. Note that the own vehicle mark 301A, 301B, 301C, 301D, 301E, 301F, 301G, and the own vehicle mark 301H may be collectively referred to as “own vehicle mark 301”.

  The bird's-eye view image 300A, the intermediate images 300B-300G, and the plane image 300H have different viewpoint positions when describing the vehicle mark 301 and its surroundings. FIG. 4 is a diagram showing an example of each viewpoint position from the side with respect to the traveling direction of the own vehicle. That is, the bird's-eye view image 300A is a diagram drawn from the viewpoint position 350A, the intermediate image 300B is a diagram drawn from the viewpoint position 350B, the intermediate image 300C is a diagram drawn from the viewpoint position 350C, and the intermediate image 300D is a diagram drawn from the viewpoint position 350C. FIG. 350D is a diagram depicted from the viewpoint position 350E, the intermediate image 300E is a diagram depicted from the viewpoint position 350F, the intermediate image 300F is a diagram depicted from the viewpoint position 350F, and the intermediate image 300G is a diagram depicted from the viewpoint position 350G. The plane image 300H is a diagram drawn from the viewpoint position 350H.

In other words, the control unit 211 displays the own vehicle mark 301 enlarged from the size of the own vehicle mark 301A displayed on the bird's-eye view image 300A, and then displays the size of the own vehicle mark 301H displayed on the plane image 300H. And display it. That is, when the image is switched from the bird's-eye view image 300A to the planar image 300H, the own vehicle mark 301 is highlighted, so that the user can be less likely to lose the own vehicle mark 301 when switching the image. In addition, the user gradually approaches (the viewpoint position 350B) from the upper rear part (the viewpoint position 350A) behind the own vehicle mark 301, approaches further while lowering the posture (the viewpoint position 350C, the viewpoint position 350D), There is a sense of presence (like a bird) that moves directly above the car mark 301 (viewpoint position 350E) and then gradually moves upward (viewpoint position 350F, viewpoint position 350G, viewpoint position 350H). A visual effect can be obtained, and it becomes clear that the own vehicle mark is a noticeable icon by the above visual effect, so that the own vehicle mark is not lost. Furthermore, at the time of switching from the bird's-eye view image 300A to the plane image 300H, by eliminating or not displaying surrounding icons or the like outside the screen due to the viewpoint moving effect or the enlargement effect, it is possible to pay more attention to the own vehicle mark. it can.

[2.2. Control of switching from point search result image to whole route image]
Next, a case where the image displayed on the display 214c is switched from the point search result image to the entire route image will be described with reference to FIG. FIG. 5 is a diagram illustrating an example of image transition when switching from the point search result image to the entire route image.

  FIG. 5A is a diagram illustrating an example of the point search result image 400A, and FIG. 5C is a diagram illustrating an example of the entire route image 400C. FIG. 5B is a diagram illustrating an example of an intermediate image 400B displayed in the process when the image is switched from the point search result image 400A to the entire route image 400C.

  The point search result image 400A is an image showing a result of searching for a point based on the set search condition. The point search result image 400A includes a list 410 of the searched points, and in a selected state where any of the points included in the list 410 is selected, the two-dimensional map 420 and the two-dimensional map 420 showing the periphery of the point are displayed. A point mark 401A indicating a point is displayed.

  Further, the point search result image 400A includes a “go here” button 402. Then, when the “Go here” button 402 is selected by the user, the control unit 211 switches the image from the point search result image 400A to the entire route image 400C. The entire route image 400C is an image that displays, along with a map, the entire route that has the destination in the list 410 that was selected when the “go here” button 402 was selected. Note that the entire route image 400C includes a destination mark 401C indicating the same target point (the searched point) as the point mark 401A of the point search result image 400A.

  As described above, the point search result image 400A is an image that displays a result of searching for a point based on the set search condition in a list format and displays a planar map 420 indicating any point in the list 410. On the other hand, the entire route image 400C is an image that displays the entire route with the destination in the list 410 as a destination, and has different display formats.

  When the user selects the “go here” button 402, the control unit 211 does not immediately switch the image from the point search result image 400A to the entire route image 400C, but uses the point search result image 400A and the intermediate image. The images are switched and displayed in the order of 400B and the entire route image 400C. The intermediate image 400B is an image in which the point selected in the state where the “go here” button 402 is selected and its surroundings are displayed larger than the planar map 420 of the point search result image 400A. At this time, the point mark 401B indicating the point selected by the user is displayed larger than the point mark 401A of the point search result image 400A.

  Although FIG. 5 shows one intermediate image 400B as an image to be displayed while switching the image from the point search result image 400A to the entire route image 400C, a plurality of intermediate images other than the intermediate image 400B are displayed. The screen may be displayed and the screen may be smoothly transitioned as a moving image.

  Specifically, the control unit 211 sequentially displays a plurality of intermediate images in order to gradually enlarge the area around the planar map 420 and the point mark 401A of the point search result image 400A after the point search result image 400A, and then Alternatively, the intermediate image 400B may be displayed. Further, the control unit 211 sequentially displays a plurality of intermediate images in order to gradually reduce and display the mark 401B of the intermediate image 400B and the planar map showing the periphery thereof next to the intermediate image 400B, and then displays the entire route image 400C. It is good also as making it do.

  Further, in addition to or separately from the display control for enlarging or reducing, the control unit 211 sequentially displays a plurality of intermediate images while switching the image from the point search result image 400A to the entire route image 400C. Thereby, the mark indicating the point (the mark of the display form of the point mark 401A or the mark of the destination mark 401C) is moved from the position of the point mark 401A in the point search result image 400A to the position of the destination mark 401C in the entire route image 400C. The display for moving to the position may be displayed. Further, the control unit 211 determines that the point mark 401A in the point search result image 400A and the destination mark 401C in the overall route image 400C are marks indicating the same point, but have different display forms. The display mode is changed from the display mode to the display mode of the destination mark 401C. As the mode of the change, in addition to the mode in which the display mode of the mark is gradually changed, the timing when the “go here” button 402 is selected, and the mode in which the mark is enlarged most in the middle of the screen transition (viewpoint The display form of the mark may be switched at the timing when the mark comes closest.

[2.3. Control of switching from whole route image to planar image]
Next, a case where the image displayed on the display 214c is switched from the entire path image to the plane image will be described with reference to FIG. FIG. 6 is a diagram illustrating an example of image transition when switching from the entire route image to the planar image.

  FIG. 6A is a diagram illustrating an example of the entire route image 500A, and FIG. 6C is a diagram illustrating an example of the planar image 500C. FIG. 6B is a diagram showing an example of the intermediate image 500B displayed in the process when the image is switched from the entire route image 500A to the plane image 500C.

  The entire route image 500A is an image showing the entire route from the current position of the vehicle to the set destination. For example, when the “go here” button 402 in FIG. Is an image displaying the entire route with the point in the list 410 corresponding to the destination as a destination together with a map. The entire route image 500A includes a current position mark 501A indicating the current position (guidance start position) of the own vehicle, and a “guide start” button 502.

  Then, when the “guidance start” button 502 is selected by the user, the control unit 211 switches the image from the entire route image 500A to the plane image 500C. The plane image 500C is an image that displays a map showing the current position mark 501A and its surroundings. Further, the plane image 500C includes an own vehicle mark 501C indicating the current position of the own vehicle which is the same target as the current position mark 501A of the overall route image 500A. In addition, the plane image 500C displays the map including the position of the own vehicle and its surroundings larger than the whole route image 500A, except when the user performs an operation of reducing the size of the map.

  As described above, the entire route image 500A is an image that displays the entire route from the current position of the own vehicle to the destination, while the planar image 500C shows the current position mark 501A and its surroundings and a part of the route. This is an image to be displayed, and each display format is different.

  When the “guidance start” button 502 is selected by the user, the control unit 211 does not immediately switch the image from the entire route image 500A to the planar image 500C, but instead switches the entire route image 500A, the intermediate image 500B, and the planar image 500A. The images are switched and displayed in the order of 500C. The intermediate image 500B is an image in which the current position mark 501A and its surroundings are displayed on a larger scale than the entire route image 500A. At this time, the current position mark 501B is displayed larger than the current position mark 501A of the entire route image 500A.

  In FIG. 6, one intermediate image 500B is shown as an image to be displayed while the image is switched from the entire route image 500A to the plane image 500C. However, a plurality of intermediate images are displayed in addition to the intermediate image 500B. Alternatively, the screen may be smoothly transitioned as a moving image.

  Specifically, the control unit 211 displays a plurality of intermediate images in order to gradually enlarge and display the planar map and the current position mark 501A of the entire route image 500A after the entire route image 500A, and then displays the intermediate image 500B May be displayed. In addition, the control unit 211 displays a plurality of intermediate images in order to gradually reduce the current position mark 501B of the intermediate image 500B and its surroundings after the intermediate image 500B, and then displays the intermediate image 500B. Is also good.

  In addition to the display control for enlarging or reducing, or separately from the display control, the control unit 211 sequentially displays a plurality of intermediate images while switching the image from the entire path image 500A to the plane image 500C. The mark indicating the own vehicle (the mark of the display form of the current position mark 501A or the display form of the own vehicle mark 501C) is changed from the position of the current position mark 501A in the entire route image 500A to the position of the own vehicle mark 501C in the plane image 500C. It may be displayed to move to. Further, the control unit 211 determines that the current position mark 501A in the overall route image 500A and the own vehicle mark 501C in the planar image 500C are marks indicating the current position of the own vehicle, but their display forms are different. The display mode is changed from the display mode of the mark 501B to the display mode of the own vehicle mark 501C. As the mode of the change, in addition to the mode of gradually changing the display mode of the mark, the timing at which the “guidance start” button 502 is selected, the mark being enlarged most in the middle of the screen transition (viewpoint A mode in which the display mode of the mark is switched at the timing of the closest approach may be adopted.

  Up to this point, the intermediate image 300B-300G is displayed while the image is switched from the bird's-eye view image 300A to the plane image 300H, or the intermediate image 400B is displayed while the image is switched from the point search result image 400A to the entire route image 400C. Although the embodiment in which the intermediate image 500B is displayed while the image is switched from the entire route image 500A to the plane image 500C has been described, in the present application, the image before the image switching (the overhead image 300A, the point search result image 400A, The process of displaying the entire route image 500A) is referred to as a first process, and the process of displaying the images after the image switching (the planar image 300H, the overall route image 400C, and the planar image 500C) is referred to as a second process. Image (intermediate image 300B-300G, intermediate image 400B, intermediate image 50 B) with a transition process a process of displaying the.

  As described above, in the vehicle device 200 according to the present embodiment, the control unit 211 (an example of the “first processing unit”, the “second processing unit”, and the “transition processing unit”) includes the own vehicle (“the predetermined target”). ) Is displayed on the display 214c (an example of the “display section”), and the overhead image 300A (an example of the “first image having the first display format”) displaying the own vehicle mark 301A (an example of the “symbol”) is displayed. ), And a plane image 300H (which has a display format different from the bird's-eye view image 300A) that displays a vehicle mark 301H (an example of a “symbol indicating the same target as the predetermined target”) indicating the vehicle. A second process of displaying “an example of a second image having a second display format” on the display 214c, and an intermediate image 300D (a “transition image” of the “transition image”) displayed while switching from the overhead image 300A to the planar image 300H. One case) There are, executes the transition process of displaying the intermediate image 300D for displaying an enlarged vehicle mark 301A, the 301H to the display 214c, the.

  Therefore, according to the in-vehicle apparatus 200 in the present embodiment, the own vehicle mark 301 indicating the own vehicle is enlarged and displayed while the image is switched from the overhead image 300A to the planar image 300H having a display format different from that of the overhead image 300A. Since the intermediate image 300D is displayed, the user can hardly lose sight of the own vehicle mark 301.

  In the vehicle device 200 according to the present embodiment, in the transition process, the control unit 211 enlarges the own vehicle mark 301 included in the intermediate images 300B to 300G from the size of the own vehicle mark 301A displayed in the overhead view image 300A. To be displayed (own vehicle marks 301B, 301C, 301D, 301E), and then reduced to the size of the own vehicle mark 301H displayed on the planar image 300H and displayed (own vehicle marks 301F, 301G). Thereby, the size of the own vehicle mark 301A before the image switching is gradually enlarged, and then gradually reduced to the size of the own vehicle mark 301H after the image switching.

Is displayed in the display form of the own vehicle mark 501C in FIG. 6C (an example of the “second display form”), and in the transition process, the mark indicating the current position of the own vehicle is displayed. It is also possible to display an intermediate image, which is a mark indicating a position and is a display form of the current position mark 501A or a display form of the own vehicle mark 501C, in an enlarged manner. In this case, even if the display form of the mark indicating the current position of the own vehicle is different between the entire route image 500A before the switch and the planar image 500C after the change, the display form of the mark indicating the current position of the own vehicle is different. Since the switching is not performed instantaneously but is performed stepwise, it is possible to prevent the user from losing the position of the mark indicating the current position of the vehicle when switching images.
