VEHICULAR MULTI-CAMERA VISION SYSTEM
First Claim
1. A vision system of a vehicle, said vision system comprising:
- a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle;
an image processing system operable to process image data captured by said plurality of cameras;
wherein, responsive to processing of captured image data, said vision system is operable to synthesize a composite image derived from image data captured by at least two cameras of said plurality of cameras;
wherein one of said plurality of cameras functions as a master camera and wherein said vision system, responsive to processing of image data captured by the master camera, determines operating parameters for the master camera; and
wherein the determined operating parameters for the master camera are used by the other cameras of said plurality of cameras.

Abstract
A vision system of a vehicle includes a plurality of cameras disposed at the vehicle and having respective fields of view exterior of the vehicle. An image processing system is operable to process image data captured by the cameras. Responsive to processing of captured image data, the vision system is operable to generate a composite image derived from image data captured by at least two cameras of the plurality of cameras. One of the plurality of cameras functions as a master camera and the vision system, responsive to processing image data captured by the master camera, determines operating parameters for the master camera. The determined operating parameters for the master camera are used by the other cameras of the plurality of cameras.

13. A vision system of a vehicle, said vision system comprising:
-
a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle; wherein said plurality of cameras each comprise a two dimensional CMOS imaging array having a plurality of photosensing pixels; wherein said plurality of cameras comprises at least a rearward viewing camera, a driver side sideward viewing camera and a passenger side sideward viewing camera; an image processing system operable to process image data captured by said plurality of cameras; wherein, responsive to processing of captured image data, said vision system is operable to synthesize a composite image derived from image data captured by at least two cameras of said plurality of cameras; wherein one of said plurality of cameras functions as a master camera and wherein said vision system, responsive to processing of image data captured by the master camera, determines operating parameters for the master camera; wherein the determined operating parameters for the master camera are used by the other cameras of said plurality of cameras; and wherein, during a reversing maneuver of the vehicle, said rearward viewing camera comprises the master camera. - View Dependent Claims (14, 15, 16, 17)

18. A vision system of a vehicle, said vision system comprising:
-
a plurality of cameras disposed at a vehicle and having respective fields of view exterior of the vehicle; wherein said plurality of cameras each comprise a two dimensional CMOS imaging array having a plurality of photosensing pixels; wherein said plurality of cameras comprises at least a forward viewing camera, a rearward viewing camera, a driver side sideward viewing camera and a passenger side sideward viewing camera; an image processing system operable to process image data captured by said plurality of cameras; wherein, responsive to processing of captured image data, said vision system is operable to synthesize a composite image derived from image data captured by said plurality of cameras; wherein the composite image comprises a bird'"'"'s eye view image; wherein one of said plurality of cameras functions as a master camera and wherein said vision system, responsive to processing of image data captured by the master camera, determines operating parameters for the master camera; wherein said vision system is operable to communicate the determined operating parameters to the other cameras; wherein the determined operating parameters for the master camera are communicated over network links to the other cameras of said plurality of cameras; and wherein the determined operating parameters for the master camera are used by the other cameras of said plurality of cameras. - View Dependent Claims (19, 20)
