FRONT CAMERA COMMUNICATION SIGNAL CIRCUIT
Description
INFOID:0000000003160721
• Around view monitor control unit supplies to the front camera, rear camera and side camera. And then it
superimpose the images from each camera and outputs then to the display unit.
• Superimpose the guiding lines, predicted course line and sonar indicator to the camera image that outputs to
the display unit.
• Around view monitor control unit performs the reception/transmission of communication signal with each
camera.
