Imaging system for vehicle

An imaging system suitable for use in a vehicle, said imaging system comprising:

• an imaging sensor comprising a two-dimensional array of photosensing pixels, said two-dimensional array comprising at least one sub-array comprising a first photosensing pixel, a second photosensing pixel, a third photosensing pixel and a fourth photosensing pixel;
• wherein spectral filtering is disposed at said first photosensing pixel whereby said first photosensing pixel primarily senses red visible light;
• wherein spectral filtering is disposed at said second photosensing pixel whereby said second photosensing primarily senses blue visible light;
• wherein spectral filtering is disposed at said third photosensing pixel whereby said third photosensing primarily senses green visible light;
• wherein spectral filtering is disposed at said fourth photosensing pixel whereby said fourth photosensing primarily senses infrared radiation;
• wherein said imaging sensor is disposed at a vehicle equipped with said imaging system and wherein, with said imaging sensor disposed at the equipped vehicle, said imaging sensor has a field of view rearward of the equipped vehicle, and wherein said imaging system is associated with a rear backup system of the equipped vehicle;
• an image processor operable for processing image data captured by said imaging sensor;
• wherein said image data comprises an output of said first photosensing pixel, an output of said second photosensing pixel, an output of said third photosensing pixel and an output of said fourth photosensing pixel;
• wherein said two-dimensional array of photosensing pixels comprises at least 262,144 photosensing pixels;
• wherein said imaging sensor comprises part of a rear viewing color camera that is operable to capture video image data;
• and
• wherein the equipped vehicle is equipped with ultrasonic sensors, and wherein an indication is given to a driver of the equipped vehicle of a presence of an object adjacent the equipped vehicle based, at least in part, on sensing by said ultrasonic sensors and on image processing by said image processor of video image data captured by said rear viewing color camera.
