1. An image capture system comprising:

  • (a) a geometric calibration plate;

    (b) an illumination calibration plate;

    (c) one or more lens(es) or optics;

    (d) an imaging system;

    (e) one or more imaging plane(s);

    (f) an image processor;

    wherein said lens (es)/optics are used in conjunction with said imaging system to image said geometric and/or illumination calibration plate(s) to form an image correction database under control of said image processor;

    said image correction database is used to create a distortion correction image under control of said image processor; and

    said image processor permits application of said image correction database and/or said distortion correction image to an input object image to produce a distortion-free output image; and

    said image processor simultaneously corrects for sources of geometric distortions, lighting variations, color variations, and magnification variances in said input object image.
