Patent ID: 7903303

Claim:
Apparatus for correcting color video signals, comprising: a matrix, through which the color video signals pass to control the proportions of three primary colors in matrixed color value signals, means for controlling the matrix as a function of hue of the color video signals respectively, means for controlling the matrix as a function of color saturation; memories for storing information which the matrix uses to control the color value signals; a converter for generating a hue signal from the color video signals, the hue signal connected to inputs of the memories; wherein the matrix comprises nine multipliers and three adders, wherein three of the nine multipliers are connected to one adder, respectively, wherein the memories store coefficients of the matrix that are set as a function of hue of the color video signals; and wherein the converter generates a color saturation signal from the color video signals, supplied to multipliers located in the supply lines of the correction values to the matrix.
