Abstract:
A disclosed scaler resource includes a color management module configured to support two or more color space transformations and two or more color temperature adjustment profiles and to receive first pixel data and perform color processing of the first pixel data to produce second pixel data. The color processing includes a color space transformation in accordance with any of the supported color space transformation matrices and a color temperature adjustment in accordance with any of the supported color temperature adjustment profiles. The color processing is configured wherein a ratio of primary colors produced by performing the color processing on first pixel data corresponding to any primary color is independent of the selected color temperature adjustment profile. The color space transformation may be performed before or after the color temperature adjustment. When performed before, the color transformation matrix is modified to reflect the color temperature adjust profile.
