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;

    at least a portion of said logic and control circuit commonly formed on said semiconductor with said array of light sensing elements;

    said logic and control circuit comprising an image processor for processing image data derived from said imaging sensor;

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

    at least one illumination source illuminating a region of interest within the field of view of said imaging sensor;

    said illumination source principally radiating in a spectral region that is outside the visible light spectrum; and

    wherein the spectral region radiated by said illumination source comprises wavelengths within the responsive range of said imaging sensor.
