摘要:
A color video display apparatus for vehicles detects a light or dark condition outside a vehicle to perform a variable gain control on a circuit for amplifying blue, green and red video signals. In response to the dark condition outside the vehicle, the amplification factor of the red video signal is increased relative to those of the blue and green video signals.
