Abstract
A method of gray component replacement receives a current pixel color value. A highlight likelihood and color neutrality is determined for the current pixel color value. An output pixel color value depending upon the color neutrality and the highlight likelihood is generated. The input pixel color value is obtained from an image acquisition system and the output color pixel value is used by an output engine to render the pixel.
