Patent ID: 8368962

Claim:
A color look up table adjusting apparatus, comprising: a color gamut acquisition unit configured to determine, from an image output by an image forming apparatus based on input color values, a lattice point indicating a position of the input color values in a color space and an area including the lattice point as a color gamut of the image forming apparatus, and further configured to determine, from an image output by another image forming apparatus based on the input color values, a position of the input color values in the color space as a target point; an interpolation process unit configured to calculate a point corresponding to the target point within the color gamut of the image forming apparatus as an adjustment point; a color value adjustment table generating unit configured to generate a color value adjustment table for converting the input Color values into converted input color values corresponding to a position of the adjustment point; and a table organization unit configured to convert arbitrary input color values based on the color value adjustment table, and inputs converted input color values as input color values based on a color look up table.
