Abstract: An imaging system suitable for use in a vehicle includes an imaging sensor having a two-dimensional array of photosensing elements, an image processor for processing image data captured by the imaging sensor, and a display for displaying images responsive to the image processor. The array has a plurality of sub-arrays, with each of the sub-arrays having a first pixel sensing primarily a first color, a second pixel sensing primarily a second color, a third pixel sensing primarily a third color and a fourth pixel sensing primarily infrared radiation. The image processor processes the output of the fourth pixel to determine an infrared component of the imaged scene and subtracts the infrared component from the outputs of the first, second and third pixels to obtain a more accurate or true color response for the pixels and to limit or avoid infrared color wash-out.
