  • Patent number: 8264497
    Abstract: In a first embodiment, a display system comprises a display panel with 4 or more colored subpixels. The display system receives input image data specified in a first color space and outputs image data specified in a second color space. The display system further comprises a gamut mapping module for mapping the input image data specified in the first color space to image data specified in the second color space. The gamut mapping module clamps out-of-gamut colors using at least a first clamping system and a second clamping system. The first and second clamping systems yield first and second clamped values. A weighting module produces a resulting clamped value from the first and second clamped values. A final output image value is derived from the resulting clamped value. Other embodiments of the display system include pre-reduction modules and adjustable GMA modules.
