REAR VIEW CAMERA IMAGE SIGNAL CIRCUIT

Description

INFOID:0000000003529077

• Camera control unit outputs camera ON signal to rear view camera and inputs rear view camera image sig-

nal from rear view camera when the reverse signal is input.

• The camera control unit that inputs the camera image signal transmits the camera image signal to the AV

control unit.
