COLOR SIGNAL PROCESSING METHOD AND APPARATUS USABLE WITH COLOR REPRODUCING DEVICE HAVING WIDE COLOR GAMUT

摘要

PPROBLEM TO BE SOLVED: To provide a color signal processing apparatus and method. PSOLUTION: The present invention relates to a color signal processing method and apparatus usable with a color reproducing device having a wide color gamut. The color signal processing method according to the present invention includes: first calculating a mixing ratio for producing a standard primary color of an input color signal by mixing source primary colors of a color reproducing device through which the input color is reproduced, reconstructing the source primary colors of the color reproducing device on the basis of the calculated mixing ratio, and transforming the input color signal to match a color gamut determined by the reconstructed primary colors and outputting the transformed color signal. Thus, the color gamut of the color reproducing device can be freely adjusted in accordance with the input color signal or its other purpose. PCOPYRIGHT: (C)2006,JPO&NCIPI
