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

  • an imaging sensor comprising a two-dimensional CMOS array of light sensing photosensor elements;

    wherein said imaging sensor has a forward field of view to the exterior of a windshield of a vehicle equipped with said image sensing system;

    wherein said imaging sensor views through the windshield of the equipped vehicle at a region of the windshield that is swept by a windshield wiper of the equipped vehicle;

    wherein said imaging sensor is operable to capture image data;

    wherein said imaging sensor is operable to capture frames of image data at a plurality of exposure periods;

    a control comprising an image processor;

    wherein said image sensing system identifies objects in said forward field of view of said imaging sensor via processing of said captured image data by said image processor;

    wherein identification of objects is based at least in part on at least one of (i) shape, (ii) luminance, (iii) geometry, (iv) spatial location, (v) motion and (vi) spectral characteristic; and

    wherein objects identified by said image sensing system comprise at least one of (i) headlights of approaching vehicles, (ii) taillights of leading vehicles, (iii) lane markers on a road being traveled by the equipped vehicle, (iv) traffic signs, (v) traffic lights, (vi) stop signs and (vii) caution signs.
