Adaptive preprocessing is performed on the three primary color signals generated during the scanning of a color image in order to enhance the perceived saturation of the dominant primary color. This preprocessing is performed by removing a small increment from the least intense primary color and adding the same increment to the most intense primary color. In this manner the overall brightness of the pixel is preserved, but the perceived saturation is increased. The increment that is effectively transferred from the least intense primary color value to the most intense primary color value is based on the relations of the three primary color values to each other in order to avoid visible color artifacts.
