ABSTRACT:
A method for adjusting the tone scale reproduction of a color image composed of pixels provided in a plurality of color channels is based on generating a reference image from a combination of the color channels, whereby each spatial coordinate of the reference image is characterized by a reference image level. Channel averages of the color channel values of the pixels that correspond to the different valued reference image levels are generated. A channel tone scale transformation is formed by relating each channel average to its corresponding reference image level, and the channel tone scale transformation is utilized on a pixel by pixel basis in the respective channels of the digital color image to produce a processed digital color image having improved tone scale reproduction.
