VEHICULAR VISION SYSTEM
First Claim
1. A vehicular vision system, said vehicular vision system comprising:
- a CMOS photosensor array comprising a plurality of photosensor elements;
wherein said photosensor array is disposed at an interior portion of a vehicle equipped with said vehicular vision system and wherein said photosensor array has a forward field of view to the exterior of the equipped vehicle through the windshield of the equipped vehicle at a windshield area that is swept by the windshield wipers;
said photosensor array having a field of view forward of the equipped vehicle that is generally in line with the equipped vehicle'"'"'s primary direction of forward travel;
a control comprising an image processor, said image processor processing image data captured by said photosensor array; and
wherein said control analyzes image data captured by photosensor elements where an object exterior of the equipped vehicle is determined to be present more than said control analyzes image data captured by other photosensor elements where the determined object is not present.

Abstract
A vehicular vision system includes a CMOS photosensor array including a plurality of photosensor elements. The photosensor array is disposed at an interior portion of a vehicle and has a forward field of view to the exterior of the vehicle through the windshield of the vehicle at a windshield area that is swept by the windshield wipers. The photosensor array has a field of view forward of the vehicle that is generally in line with the vehicle'"'"'s primary direction of forward travel. A control includes an image processor that processes image data captured by the photosensor array. The control may analyze image data captured by photosensor elements where an object exterior of the equipped vehicle is determined to be present more than the control analyzes image data captured by other photosensor elements where the determined object is not present.
