Abstract
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′.
