Abstract
Image decoders encoders and transcoders incorporate gamut transformations. The gamut transformations alter tone, color or other characteristics of image data. The gamut transformations may comprise interpolation, extrapolation, direct mapping of pixel values and/or modification of an expansion function. Gamut transformations may be applied to generate image output (video or still) adapted for display on a target display.
