Claim Text:
1. A dynamic gamut display system method for solid state light based displays using emissive micro-pixel array devices wherein each color of each pixel is independently controllable without a backlight, each solid state light based display having a display native gamut, comprising: buffering in a buffer, an input video frame pixel data expressed relative to a defined three primary reference color gamut having a defined reference white point; processing the input video frame pixel data as the input video frame pixel data is entered into the buffer to calculate a set of gamut metrics for the respective video frame representing, for each primary reference color in the input video frame pixel data, a respective mean and spread from the mean in the input video frame pixel data around the white point of the reference color gamut; calculating a set of gamut scale factors that represent the distribution of each primary reference color in the input video frame pixel data around the white point of the reference color gamut; using the gamut scale factors, determining an adapted color gamut around the white point of the reference color gamut; using a matrix for converting pixel color values from the reference gamut to the adapted color gamut and the gamut scale factors, converting the buffered input video frame pixels data from the reference color gamut to the adapted color gamut; and outputting the adapted gamut, and outputting the buffered input video frame pixel data as converted from the reference color gamut to the adapted color gamut, to a display of the dynamic gamut display system, both outputs being expressed in the display native gamut.
