  • Method of estimating colors for color image correction
    Patent number: 5087126
    Abstract: In a method of estimating colors of this invention, a combination of fundamental colors (x y z . . . ), which corresponds to a target color in a colorimetric system, is calculated by using the following equation: ##EQU1## where (x.sub.i ', y.sub.i ', z.sub.i ', . . . ) (i=1 to (n+1)) are values of (n +1) vertexes of a division space, which surround the target value in the colorimetric system, (x.sub.i, y.sub.i, z.sub.i, . . . ) (where i=1 to (n+1)) are values of vertexes of a division space of a fundamental color coordinate system corresponding to the division space in the colorimetric system, and (x', y', z', . . . ) is a value of the target color in the colorimetric system.
