Abstract

A color mapping method is used in transforming colors between color imaging systems. The method includes using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems. Color conversions are calculated by recursively reducing differences between the respective sets of device-independent color values. Based on these color conversions, a color map is constructed that describes a relationship between the color imaging systems.

1 . For use in transforming colors between color imaging systems, a color mapping method comprising: 
 using forward transformation profiles that characterize the color imaging systems to generate respective sets of device-independent color values for the color imaging systems;    calculating color conversions by recursively reducing differences between the sets of device-independent color values; and    constructing a color map describing a relationship between the color imaging systems using the color conversions.
