Rear vision system for a vehicle

A camera vision system for a vehicle, said camera vision system comprising:

• a rear backup video camera at a rear portion of a vehicle equipped with said camera vision system;
• wherein said rear backup video camera comprises a CMOS imaging array;
• said rear backup video camera having a rearward field of view external of the equipped vehicle;
• said rear backup video camera operable to capture video images rearward of the equipped vehicle during a rear backup maneuver of the equipped vehicle;
• a display device comprising a video screen operable to display video images captured by said rear backup video camera for viewing by a driver of the equipped vehicle who is maneuvering the equipped vehicle;
• wherein video images captured by said rear backup video camera are displayed by said display device when a transmission of the equipped vehicle is shifted into reverse gear by the driver and wherein said display by said video device of video images captured by said rear backup video camera continues during short term forward movement of the equipped vehicle;
• wherein an overlay is displayed with video images captured by said rear backup video camera to assist the driver during the rear backup maneuver;
• wherein said video screen of said display device comprises a backlit thin film transistor LCD video screen backlit by a plurality of white light emitting light emitting diodes;
• wherein said plurality of white light emitting light emitting diodes comprises an array of at least four white light emitting light emitting diodes;
• wherein said display device is operable to display video images captured by said rear backup video camera with a display intensity, as viewed by the driver of the equipped vehicle, greater than 200 candelas/sq. meter;
• a control comprising an image processor that image processes video images captured by said rear backup video camera in order to detect objects that are within the rearward field of view of said rear backup video camera and that are at least one of (i) near to a vehicle bumper of the equipped vehicle and (ii) approaching the equipped vehicle;
• wherein image processing by said image processor of captured video images comprises use of an edge detection algorithm;
• wherein the equipped vehicle is further equipped with a sensor system selected from the group consisting of (i) a radar sensor system and (ii) an ultrasonic sensor system;
• wherein said sensor system monitors a region external to the vehicle;
• and
• wherein said sensor system detects the presence of an obstacle and/or a human adjacent to the equipped vehicle.
