Methods and apparatus for color uniformity

An apparatus for achieving color uniformity in a color output device, the apparatus comprising:

• a first module adapted to record luminance and chrominance values for a plurality of positions on a display surface;
• a second module adapted to construct a color gamut for each of said positions, wherein each color gamut is based at least in part upon said luminance and chrominance values;
• a third module adapted to construct a common color gamut based at least in part upon the color gamuts constructed by the second module;
• and
• a fourth module adapted to receive a source color gamut and map at least a portion of the source color gamut into the common color gamut.

A method of mapping a color set producible by a set of positions associated with a first display surface to a color set producible by a target position associated with a second display surface, the method comprising:

• generating a first color gamut for the first set of positions;
• generating a second color gamut for the target position;
• generating a common color gamut based at least in part upon the first and second color gamuts;
• and
• mapping the first color gamut to the common color gamut.
