Abstract: A camera cleaning system for a vehicle includes a camera including a lens cover and a motor. A cleaning assembly includes an arm including a cleaning material. The motor selectively adjusts a position of the arm and the cleaning material relative to the lens cover of the camera. The motor selectively adjusts a position of the arm and the cleaning material relative to vehicle from a first position to a second position. The camera selectively generates video signals when the camera is in the first position. The cleaning assembly is in contact with the lens cover when the camera is in the second position

Abstract: A system and method for creating an enhanced perspective view of an area in front of a vehicle, using images from left-front and right-front cameras. The enhanced perspective view removes the distortion and exaggerated perspective effects which are inherent in wide-angle lens images. The enhanced perspective view uses a camera model including a virtual image surface and other processing techniques which provide corrections for two types of problems which are typically present in de-warped perspective images—including a stretching effect at the peripheral area of a wide-angle image de-warped by rectilinear projection, and double image of objects in an area where left-front and right-front camera images overlap.
