Patent ID: 8643908

Claim:
A color adjustment device comprising: a conversion unit that converts color values of a second color space stored in a color conversion table, which defines a correspondence relation between color values of a first color space and color values of the second color space, into color values of a third color space independent from a device outputting an image; a storage unit that stores tables that have characteristics that output values with respect to an input value differing from each other depending on color values of the third color space; a reception unit that receives an adjustment instruction for saturation; a map storing unit that stores a map for determining a table to be used for color adjustment in accordance with an instruction for increasing or decreasing the saturation, wherein the map is used to select the table to be used for the color adjustment from the tables stored in the storage unit, wherein the map is prepared with respect to each color element of color values of the second color space, wherein the map indicating that the table to be used for the color adjustment differs depending on color values of the third color space, and wherein the map includes a map used when an instruction for increasing the saturation is received and a map used when an instruction for decreasing the saturation is received; and a change unit that selects at least one table from the tables by referring to the map stored in the map storing unit based on the instruction for increasing or decreasing the saturation, and executes a change process that changes color values of the second color space stored in the color conversion table by using the at least one table.
