Claim 18:
19. A vehicular vision system, said vehicular vision system comprising:
a rear backup camera disposed at a vehicle equipped with said vehicular vision system, said rear backup camera viewing at least rearward of the equipped vehicle;
said rear backup camera comprising a CMOS imaging sensor operable to capture image data;
an electronic control unit (ECU) disposed at the vehicle and comprising (i) a data processor and (ii) a DC power supply;
wherein image data captured by the CMOS imaging sensor of said rear backup camera is conveyed from said rear backup camera to the ECU via a single core coaxial cable;
wherein said rear backup camera is in bidirectional communication with the ECU over the single core coaxial cable;
wherein the single core coaxial cable commonly carries (i) image data captured by the CMOS imaging sensor of said rear backup camera to the ECU for processing at the data processor of the ECU and (ii) power from the DC power supply of the ECU to said rear backup camera;
wherein said rear backup camera comprises a data serializer and the ECU comprises a data deserializer, and wherein image data captured by the CMOS imaging sensor is serialized at the data serializer and is conveyed to the ECU via the single core coaxial cable and is deserialized at the ECU by the data deserializer;
wherein the vehicular vision system, responsive to processing at the ECU of image data captured by said rear backup camera and conveyed to the ECU via the single core coaxial cable, generates an output provided to a video display device of the equipped vehicle; and
wherein said video display device is operable to display video derived from image data images captured by the rear backup camera of the equipped vehicle during a reversing maneuver of the equipped vehicle to assist a driver of the equipped vehicle in backing up the equipped vehicle.
