REAR VISION SYSTEM FOR VEHICLE WITH DUAL PURPOSE SIGNAL LINES
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a camera disposed at a vehicle and having a field of view exterior of the vehicle, wherein said camera is operable to capture image data;
wherein said camera comprises a circuit board and an imager disposed at said circuit board, wherein said imager comprises a two-dimensional photosensor array of photosensing pixels;
an image processor disposed at said circuit board of said camera, wherein said circuit board has circuitry disposed thereat;
wherein said image processor is operable to process image data captured by said camera;
wherein signals to and from said image processor are provided on at least one shared line connected between an electrical connector of said camera and a vehicle control of the vehicle; and
wherein said at least one shared line comprises at least one combined camera control and camera programming line, and wherein signals carried on said combined camera control and camera programming line (i) control operation of said camera and (ii) program said camera.

Abstract
A vision system of a vehicle includes a camera disposed at a vehicle and having a field of view exterior of the vehicle. The camera is operable to capture image data. The camera includes a circuit board and an imager disposed at the circuit board. An image processor is disposed at the circuit board, which has circuitry disposed thereat. The image processor is operable to process image data captured by the camera. Signals to and from the image processor are provided on at least one shared line connected between an electrical connector of the camera and a vehicle control of the vehicle. The at least one shared line includes at least one combined camera control and camera programming line. Signals carried on the combined camera control and camera programming line (i) control operation of the camera and (ii) program the camera.
