Vehicle vision system with gray level transition sensitive pixels
First Claim
1. A vision system for a vehicle, said vision system comprising:
- at least one camera configured to be disposed at a vehicle so as to have a field of view exterior of the vehicle;
wherein said at least one camera comprises at least one pixelated imaging array having a plurality of photosensing elements;
wherein said at least one pixelated imaging array comprises a plurality of event-based gray level transition sensitive photosensing elements;
a processor operable to process data captured by said at least one camera;
wherein, responsive to processing of captured data, said processor is operable to detect objects present in the field of view of said at least one camera; and
wherein said at least one pixelated imaging array comprises a first imaging array comprising visible light sensitive photosensing elements and a second imaging array comprising said plurality of event-based gray level transition sensitive photosensing elements.

Abstract
A vision system of a vehicle includes at least one camera disposed at a vehicle and having a field of view exterior of the vehicle. The camera has at least one pixelated imaging array having a plurality of photosensing elements. The pixelated imaging array includes a plurality of event-based gray level transition sensitive photosensing elements. A processor is operable to process data captured by the camera and, responsive to processing of captured data, the processor is operable to detect objects present in the field of view of the camera. The pixelated imaging array may include a first imaging array having visible light sensitive photosensing elements and a second imaging array having the plurality of event-based gray level transition sensitive photosensing elements.
