Abstract
An imaging system suitable for use in a vehicle includes an imaging sensor having a two-dimensional array of photosensing pixels that includes at least one sub-array having a first photosensing pixel, a second photosensing pixel, a third photosensing pixel and a fourth photosensing pixel. Spectral filtering is disposed at the photosensing pixels whereby the first photosensing pixel primarily senses red visible light, the second photosensing primarily senses blue visible light, the third photosensing primarily senses green visible light and the fourth photosensing primarily senses infrared radiation. The imaging sensor is disposed at a vehicle and has a field of view external of the vehicle. An image processor is operable for processing image data captured by the imaging sensor. The image data includes outputs of the first, second, third and fourth photosensing pixels. The processing of image data by the image processor may include de-mosaicing that reduces infrared color wash-out.
