1. A method of producing gamma corrected values, comprising:

  • (a) using initial, linearly derived gamma values to produce gray level images for a color;

    (b) measuring the gray level images;

    (c) obtaining the brightness-voltage (B-V) characteristics of the gray level images;

    (d) calculating new gamma corrected values that produce a predetermined response from the obtained characteristics of the gray level images;

    (e) using the newly calculated gamma corrected values in step (d) to produce new gray level images;

    (f) measuring the gray level images produced in step (e);

    (h) obtaining the brightness-data characteristics of the gray level images from the measurements of step (f); and

    (i) repeating steps (d) through (h) until the gamma corrected values produce brightness-data characteristics that meet predetermined characteristics.
