Abstract
A vehicular imaging system includes a camera with an imaging sensor. A red-pass spectral filter is disposed at each pixel of a first set of photosensing pixels, a blue-pass spectral filter is disposed at each pixel of a second set of photosensing pixels, a green-pass spectral filter is disposed at each pixel of a third set of photosensing pixels, and each pixel of a fourth set of photosensing pixels senses at least near infrared radiation. A near infrared illumination source is operable to emit non-visible near infrared illumination to enhance nighttime viewing by the camera. Outputs of the pixels of the first, second and third sets of photosensing pixels are processed for at least one of (i) a lane departure warning system and (ii) an object detection system. Output of the photosensing pixels of the fourth set of photosensing pixels is processed for a night vision system.
