Claim Text:
1. A method of encoding image data for transmission to a downstream device, the method comprising: receiving image data, the image data having a format and a content gamut; determining one or more gamut characteristics of the image data; based at least in part on the gamut characteristics, determining a localized gamut definition for the image data; and applying a gamut transform to the image data wherein color coordinates specified by the image data are mapped to corresponding color coordinates of the localized gamut definition; and wherein a gamut of the image data having the format is a range of colors capable of being represented by the format; the content gamut of the image data is a range of colors present in the image data; and the localized gamut definition defines fewer color coordinate values than the gamut of the image data having the format.
