ABSTRACT:
A method is provided for attenuating image color-cast corrections. The method comprises: selecting a highlight color; accepting a digital image of colored pixels; calculating the difference between the color of at least one pixel and the highlight color; determining an illuminant correction for the digital image; and, attenuating the image illuminant correction for at least one pixel in response to the calculated color differences. In some aspects of the method, a highlight color with a plurality of color components is selected, for example, white. Then, calculating the difference between the color of at least one pixel and the highlight color includes calculating the difference of at least one color component of the pixel from the corresponding component in the highlight color.
