In-vehicle image display system
First Claim
1. An in-vehicle image display system for a vehicle, the image display system comprising:
- a primary display device configured to include a first image-drawing unit and a first display screen for displaying a first window;
a secondary display device configured to include a second image-drawing unit and a second display screen for displaying a second window; and
a dedicated line configured to enable the primary display device to dedicatedly communicate with the secondary display device,wherein;
when it is requested that the second window displayed in the second display screen be different from the first window displayed in the first display screen,the first window is displayed in the first display screen based on a first image signal, which is generated by the first image-drawing unit,while the second window is displayed in the second display screen based on a second image signal, which is generated by the second image-drawing unit; and
when it is requested that the second window displayed in the second display screen be identical to the first window displayed in the first display screen,the first window is displayed in the first display screen based on the first image signal generated by the first image-drawing unitwhile the second window is displayed in the second display screen based on the same first image signal, which is generated by the first image-drawing unit instead of the second image-drawing unit and then transferred via the dedicated line to the secondary display device.

Abstract
In an in-vehicle image display system, each of a car navigation device and a rear-seat display device includes an own image-drawing IC. The car navigation device interfaces with a TV tuner and a DVD player. When receiving a request signal from the rear-seat display device, the car navigation device forwards relevant image data to the rear-seat display device using a dedicated line. The rear-seat display device converts the forwarded image data to image signals using the own image-drawing IC to thereby display them. Thus, the car navigation device and the rear-seat display device can display different display window images with a simple system structure where no image-drawing IC used for the rear-seat display device is provided within the car navigation device.

4. An in-vehicle image display system for a vehicle, the image display system comprising:
-
a single primary display device configured to include a first image-drawing unit and a first display screen for displaying a first window, the primary display device further configured to obtain image data from a plurality of apparatuses provided in the vehicle; at least one secondary display device configured to include a second image-drawing unit and a second display screen for displaying a second window; and a dedicated line configured to enable the primary display device to dedicatedly communicate with the secondary display device, wherein; when it is requested that the second window displayed in the second display screen be different from the first window displayed in the first display screen, the first window is displayed in the first display screen based on a first image signal, the image data being generated by the first image-drawing unit using image data obtained from one of the plurality of apparatuses, while the second window is displayed in the second display screen based on a second image signal, the second image signal being generated by the second image-drawing unit using image data, the image data being obtained by the primary display device from one of the plurality of apparatuses and then transferred via the dedicated line to the secondary display device; and when it is requested that the second window displayed in the second display screen be identical to the first window displayed in the first display screen, the first window is displayed in the first display screen based on the first image signal generated by the first image-drawing unit using image data obtained from one of the plurality of apparatuses while the second window is displayed in the second display screen based on the same first image signal, which is generated by the first image-drawing unit instead of the second image-drawing unit and then transferred via the dedicated line to the secondary display device. - View Dependent Claims (5, 6, 7, 8, 9, 10, 11, 12)
