Abstract:
1. A method for mapping color data, which has a color associated therewith, to an output device based on an input-device profile and an output-device profile, each of the input-device profile and the output-device profile having a tone curve and a color matrix, the method comprising: receiving by a processing unit color data from an input device; determining by the processing unit that the color data is not in a linear space; applying by the processing unit the tone curve of the input-device profile to the color data to convert the color data into an input linear space; determining whether performance considerations are more important to mapping the color data than fidelity considerations; converting by the processing unit the color data from the input linear space to an output linear space by applying the color matrix of the input-device profile and the inverse color matrix of the output-device profile thereto to create color-converted color data, mapping by the processing unit the inverse tone curve of the output-device profile into the color-converted color data to convert the color-converted color data into mapped color data.
