Abstract

An on-vehicle display device includes: an image generation unit that generates a first image that can be viewed from a driver'"'"'s seat side and a second image that can be viewed from a passenger'"'"'s seat side; and a display monitor at which the first image and the second image are displayed within a screen, and the image generation unit does not include an image of an icon or a button, operation of which by a driver is restricted, in the first image, includes the image of the icon or the button in the second image, and constantly changes a display position of the icon or the button in the second image.

Claims

1. An on-vehicle display device, comprising:

an image generation unit that generates a first image that can be viewed from a driver'"'"'s seat side and a second image that can be viewed from a passenger'"'"'s seat side; and

a display monitor at which the first image and the second image are displayed within a screen, wherein;

the image generation unit does not include an image of an icon or a button, operation of which by a driver is restricted, in the first image, includes the image of the icon or the button in the second image, and constantly changes a display position of the icon or the button in the second image.

2. An on-vehicle display device according to claim 1, wherein:

the image generation unit changes the display position of the icon or the button randomly.

3. An on-vehicle display device according to claim 1, wherein the image generation unit includes:

a first image generation unit that generates a map image;

a second image generation unit that generates an image of the icon or the button; and

a superimposing unit that superimposes the image of the icon or the button over the map image.

4. An on-vehicle display device according to claim 1, wherein:

the icon or the button, the operation of which by the driver is restricted, is a menu button operated to display a menu screen.

5. An on-vehicle display device according to claim 1, wherein:

the image generation unit generates an image of an icon or a button, the operation of which by the driver is not restricted, in the first image and the second image.

6. An on-vehicle display device according to claim 1, wherein:

the image generation unit also generates a map image and an image of an icon or a button, the operation of which by the driver is not restricted, includes the map image and the image of the icon or the button, the operation of which by the driver is not restricted in the first image, and includes the map-image, the image of the icon or the button, the operation of which by the driver is not restricted and the image of the icon or the button, the operation of which by the driver is restricted in the second image; and

the icon or the button, the operation of which by the driver is restricted is a menu button operated to display a menu screen and the icon or the button, the operation of which by the driver is not restricted is a button to be operated to indicate wide area/detailed setting for the map image.

7. An on-vehicle display device according to claim 1, wherein:

a touch panel that forms a touch switch by interlocking with an icon or a button on display, is disposed over a display screen at the display monitor.

8. A display method to be adopted in an on-vehicle display device, comprising:

generating a first image that can be viewed from a driver'"'"'s seat side and a second image that can be viewed from a passenger'"'"'s seat side;

generating an image of an icon or a button, operation of which by the driver is restricted;

displaying the first image and the second image within a monitor screen so as to allow the first image to be viewed from the driver'"'"'s seat side and the second image to be viewed from the passenger'"'"'s seat side; and

displaying the icon or the button in the second image alone.

9. A display method to be adopted in an on-vehicle display device according to claim 8, wherein:

the first image and the second image both include a map image; and

an icon or a button other than the icon or the button, the operation of which by the driver is restricted, is superimposed over the map image in the first image, and icons and buttons including the icon or the button the operation of which by the driver is restricted, are superimposed over the map image in the second image.
