detailed description

Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an in-vehicle display system of the present invention. As shown in the figure, a car 1 includes a rearview mirror 2 , a front seat 7 , a rear seat 3 , a steering wheel 4 , and a display device 5 . According to an aspect of the present invention, a camera (not shown) is located at the front side of the driver to capture the facial image of the driver and transmit the captured facial image to the display device located at the back of the front seat 7 . The camera can be powered by the vehicle power supply system in the car, or the camera can be directly connected to the cigarette lighter in the car for power supply.
