Abstract

A camera vision system for a vehicle includes a rear backup video camera operable to capture video images rearward of the vehicle during a rear backup maneuver of the vehicle. A display device is operable to display video images captured by the rear backup video camera when the vehicle is shifted into reverse gear and the display continues during short term forward movement of the vehicle. An overlay is displayed with the video images to assist the driver during the rear backup maneuver. The display device is operable to display video images with a display intensity greater than 200 candelas/sq. meter. A control includes an image processor that image processes video images to detect objects that are within the rearward field of view of the rear backup video camera. The image processing by the image processor of captured video images includes use of an edge detection algorithm.
