Abstract

The present invention provides an in-vehicle display apparatus including a switching button 151 that switches between a single display mode displaying the same images on the basis of a single image source on first and second screens, and a dual display mode displaying D-seat and P-seat images on the basis of different image sources or the same image source on the first and second screens, respectively. Therefore, according to user'"'"'s request, it is possible to switch between a case where the same images are displayed on the first and second screens, and a case where the different images are displayed on the first and second screens, respectively.

Claims

1. An in-vehicle display apparatus comprising:

a display control means that causes first and second images to be displayed on a common display unit, the first and second images being capable of being watched from first and second viewing directions, respectively;

a display mode switching means that switches between a single display mode displaying images on the basis of a common image source on the display unit, and a dual display mode displaying the first and second images on the basis of different image sources or the same image source on the display unit so that the first and second images are capable of being watched from the first and second viewing directions, respectively; and

an operating mode switching means that switches between a first operating mode which permits to operate the first image, and a second operating mode which permits to operate the second image;

wherein the display mode switching means and the operating mode switching means include a common operating unit.

2. The in-vehicle display apparatus as claimed in claim 1, wherein the display mode switching means switches between the single display mode and the dual display mode when a time period for operation to the operating unit is more than a given time period, and

the operating mode switching means switches between the first operating mode and the second operating mode when the time period for operation is less than the given time period in the dual display mode.

3. The in-vehicle display apparatus as claimed in claim 1, wherein the first viewing direction is a driver'"'"'s seat direction, and the second viewing direction is a front passenger'"'"'s seat direction.

4. The in-vehicle display apparatus as claimed in claim 1, wherein the first image is a navigation image, and the second image is a television image.

5. The in-vehicle display apparatus as claimed in claim 2, wherein the given time period is 0.8 seconds.

6. The in-vehicle display apparatus as claimed in claim 1, further comprising a lighting portion that changes a lighting state depending on a set type of the single display mode and the dual display mode and/or a set type of the first operating mode and the second operating mode.

7. The in-vehicle display apparatus as claimed in claim 6, wherein the lighting portion is formed integrally with the display mode switching means and/or the operating mode switching means.

8. The in-vehicle display apparatus as claimed in claim 6, wherein the lighting portion is turned on, turned off, blinked depending on a set type of the single display mode and the dual display mode and/or a set type of the first operating mode and the second operating mode.

9. The in-vehicle display apparatus as claimed in claim 6, wherein the lighting portion is turned off when a setting mode is the single display mode, the lighting portion is turned on when the setting mode is the first operating mode, the lighting portion is blinked when the setting mode is the second operating mode.

10. The in-vehicle display apparatus as claimed in claim 6, wherein brightness of the lighting portion during lighting is automatically adjusted according to brightness in a vehicle.
