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

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

    wherein said imager is disposed at or proximate to an in-cabin portion of a windshield of a vehicle equipped with said image sensing system, and wherein said imager has a forward field of view to the exterior of the equipped vehicle through the windshield of the equipped vehicle;

    wherein said photosensor array is operable to capture image data;

    a control comprising an image processor;

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

    wherein said image sensing system is operable to identify at least one of (i) approaching headlights, (ii) leading taillights, (iii) lane markers, (iv) traffic signs, (v) traffic lights, (vi) stop signs and (vii) caution signs;

    wherein said photosensor array is operable to capture frames of image data; and

    wherein said image sensing system includes an exposure control which determines an accumulation period of time that said photosensor array senses light when capturing a frame of image data.
