ABSTRACT:
An efficient method for gamut clipping based on user-defined constraints on lightness and hue by: a) defining a color gamut surface of an output device using a gamut descriptor; b) specifying a search range based on maximum tolerances for lightness and hue changes; and, c) for each input color data point outside the gamut, mapping the data point to the closest point in a portion of the gamut surface specified by the search range.
