Method of mapping source colors from a source color gamut into a target color gamut

摘要

In one implementation, the method includes applying color gamut mapping directly to incoming RGB color coordinates resulting in mapped source coordinates R″G″B″. The source coordinates are then transformed into target coordinates R′G′B′. According to another implementation, incoming source coordinates RGB are transformed into target coordinates R″G″B″ and the color gamut mapping is applied directly to the target coordinates R″G″B″ resulting in mapped target coordinates R′G′B′.

1. Method of, in a color mapper, mapping source colors represented by color coordinates in a source device-dependent color space from a source color gamut into the target color gamut of a target color device thus resulting in target colors represented by color coordinates in the target device-dependent color space of said target color device, comprising:
in said source device-dependent color space, mapping each of said source colors from said source color gamut into said target color gamut resulting in a target color represented by color coordinates in said source device-dependent color space, and transforming the color coordinates representing said target color in said source device-dependent color space into color coordinates representing said target color in said target device-dependent color space.
