Abstract
An image sensing system for a vehicle includes an imaging sensor comprising a two-dimensional array of light sensing photosensor elements formed on a semiconductor substrate. The imaging sensor is disposed at an interior portion of the vehicle, and may be at or proximate to an interior rearview mirror assembly of the vehicle. The system includes a logic and control circuit comprising an image processor for processing image data derived from the imaging sensor. The image sensing system may identify objects of interest based on spectral differentiation or by comparing over successive frames image data associated with objects in the forward field of view of the image sensor or by objects of interest being at least one of qualified and disqualified based at least in part on object motion in the field of view of the imaging sensor.
