Patent ID: 6931152

Claim:
A method for providing partial color constancy of a stimulus represented by an array of picture elements each represented by a color spectrum the method comprising: assigning to each picture element in the array, for each color, a color value, thereby to provide a plurality of pre-processed single color images each respectively arranged as a series of pre-processed color values one at each picture element; for each picture element, defining at least two regions of picture elements; at each picture element, adapting each one of said pre-processed color values using pre-processed color values from at least one of said two regions of picture elements, thereby to form, at each picture element, a set of center response values; and at each picture element, transforming said set of center response values into a set of center corrected color values, using response values from said two regions of picture elements to provide a plurality of processed single color images having partial color constancy.
