A method for processing a digital input image data indexed to represent positions on a display such that the digital data is indicative of an intensity value for each position. The intensity value for each position is adjusted to generate an enhanced value based on retinex theory by operating only on a luminance channel to essentially eliminate shading and color distortion problems.
