FRONT CAMERA IMAGE SIGNAL CIRCUIT
FRONT CAMERA IMAGE SIGNAL CIRCUIT
Description
INFOID:0000000006216352
• 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 front display unit.
• Superimpose the guiding lines, predictive course line and sonar indicator to the camera image that outputs
to the front display unit.
• Around view monitor control unit performs the reception/transmission of communication signal with each
camera.
