Claim 20:
21. The method of claim 20, further comprising comparing the calculated average brightness for each image segment to an upper and a lower brightness threshold, and:
if the calculated average brightness is below the lower brightness threshold for a particular image segment then increasing the power to one or more of the plurality of light sources capable of illuminating the area corresponding to that image segment; or
if the calculated average brightness is above the upper brightness threshold for a particular image segment then decreasing the power to one or more of the plurality of light sources capable of illuminating the area corresponding to that image segment; or
if the calculated average brightness for a particular image segment lies between the upper and lower brightness thresholds then not making any changes to the power to the one or more of the plurality of light sources capable of illuminating the area corresponding to that image segment.
