1. An image sensing system for a vehicle, said image sensing system comprising:

  • an imaging sensor;

    said imaging sensor comprising a two-dimensional array of light sensing photosensor elements formed on a semiconductor substrate;

    a logic and control circuit;

    said logic and control circuit comprising an image processor for processing image data derived from said imaging sensor, said logic and control circuit generating at least one control output for controlling at least one accessory of the vehicle;

    said imaging sensor disposed at an interior portion of the vehicle and having a field of view exterior of the vehicle through a window of the vehicle;

    a lens imaging light external to the vehicle onto said imaging sensor;

    at least one object of interest within said field of view of said imaging sensor;

    a portion of said array of light sensing photosensor elements capturing an image of said at least one object of interest; and

    said logic and control circuit analyzing particular groupings of photosensor elements from said portion of said array while ignoring other particular groupings of photosensor elements from said portion of said array so as to determine at least one of presence, size, shape, contour and motion of said at least one object of interest, wherein said particular groupings of photosensor elements and said other particular groupings of photosensor elements are within a region of said array where an object of interest is expected to be imaged.
