Patent ID: 8390642

Claim:
A system, comprising: a liquid crystal display (LCD) panel having a native transfer function to transform a plurality of adjusted input values and output a plurality of gamma corrected input values and a native light output function to transform the gamma corrected input values into a plurality of light output levels; an LCD backlight having a plurality of light emitting diode (LED) modules; and a color gamut mapping engine to adjust a plurality of input values corresponding to a video signal and output a plurality of adjusted input values such that the transformation of the adjusted input values to the light output levels complies with at least one color space setting specified by a user; and a color calibration user interface to allow the user to modify the at least one color space setting, in which the color gamut mapping engine further comprises: a device compensation block comprising: at least one matrix multiplier to multiply the gamma corrected input value associated with each of the input values by a transformation matrix and output a plurality of multiplied input values; and an inverse native transfer function to apply an inverse of the native transfer function to the multiplied input values and output the adjusted input values; in which the transformation matrix is a combination of an inverse of the native light output function and a light output function corresponding to the transfer function specified by the at least one color space setting.
