1. A hardware-implemented color video data correction filtering system, comprising:

  • a plurality of linearization tables to gamma decompensate input color video data referenced to a non-linear color space;

    a plurality of a set of pre-calculated gamut shifting arrays to compensate for color point data of a plurality of constituent colors of a color monitor with each set of pre-calculated gamut shifting arrays coupled to one linearization table of the plurality of linearization tables;

    a plurality of hardware adders with each hardware adder coupled to one of the of pre-calculated gamut shifting arrays; and

    a plurality of non-linearization tables coupled to the plurality of hardware adders to compensate for non-linearities of the color monitor and produce output color video data compensated for non-linearities and color points of the color monitor.
