摘要:
Techniques are described that can be used to provide color space conversion for images and video to a display color gamut space. Some techniques provide for accessing an sRGB gamut color table, determining a color conversion matrix based on the sRGB gamut color table and chromaticity values of RGBW primary and gamma stored in the display or associated with the display, applying color space conversion to the pixels for pixels using the color conversion matrix, and applying linear correction of pixels by applying a normalization factor to the color conversion matrix. In addition, some techniques provide analysis of content gamut with respect to display gamut in HSV space, adjustment in HSV space, and conversion back to RGB space before applying color space conversion.
