Abstract

A vehicular vision system includes a rear backup camera and a controller having an image processor. A video display screen is disposed in the vehicle and viewable by a driver of the vehicle. With the vehicular vision system operating in a standard viewing mode, image data captured by the rear backup camera is processed to provide video images representative of a standard view rearward of the vehicle that is within the field of view of the rear backup camera. With the vehicular vision system operating in a cross-traffic viewing mode, image data captured by the rear backup camera is processed at the image processor to provide video images derived from the processed captured image data that are representative of a wider angle view rearward of the vehicle that has a wider angle view than the standard view rearward of the vehicle.
