Abstract
In various embodiments, a color gamut mapper includes a gamut map selection generator configured to analyze color space signals and generate a gamut map selection signal in response thereto. A color gamut transformer is configured to process the color space signals via a selected one of a plurality of gamut maps to generate gamut mapped color space signals, wherein the selected one of the plurality of gamut maps is selected in response to the gamut map selection signal. Other embodiments are disclosed.
Claims7
A dynamic ranger converter comprising:
- a color volume transformer to receive one of either configuration data or dynamic color transform metadata, and gamut shaped color components at a first dynamic range, wherein the dynamic color transform metadata determines a second dynamic range;
- reprogrammable tables programmed in response to the dynamic color transform metadata;
- and
- a transfer function interpolator to directly translate the gamut shaped color components based upon the reprogrammable tables, and to generate transform color space signals.
