Patent ID: 8610980

Claim:
A table generating apparatus that generates a look-up table that associates output color data with input color data, comprising: a processing unit that performs editing processing on lightness and saturation of the input color data which is present within a first color gamut for representing the input color data and outside a second color gamut of an output apparatus; a detecting unit that detects a region which is present within the first color gamut and near a maximum saturation of the second color gamut of the output apparatus; a correcting unit that corrects signal values of the input color data, which has undergone the editing processing and which is present within the region near the maximum saturation detected by said detecting unit and outside the second color gamut, so as to increase saturation of the input color data based on a difference in lightness of the input color data before and after the editing processing; and a storing unit that stores, in the look-up table, the signal values corrected by said correcting unit as the output color data.
