摘要: Methods and apparatus are provided for encoding and decoding image data using localized gamut definitions. The localized gamut definitions may be defined based on gamut characteristics of the image data. A gamut transform is applied to the image data wherein color coordinates specified by the image data are mapped to corresponding color coordinates in the localized gamut definition. Use of localized gamut definitions may facilitate image data compression or increased color depth specification of image data.
