Patent attributes
A vehicular vision system includes a camera having a housing and a lens barrel including a lens. The camera is configured to be disposed at an exterior portion of a vehicle so as to have a field of view exterior of the vehicle. An image processor is operable to process frames of image data captured by the camera. A heating device is disposed at or near the lens and is activated to initially heat the lens responsive to determination, via processing by the image processor of a frame of captured image data, of a threshold degree of lens occlusion at the lens. The heating device is (i) deactivated responsive to determination that the determined lens occlusion is not water or moisture, or (ii) further powered to increase the heating function responsive to determination that the determined occlusion is water or moisture.
