Abstract:
An apparatus forms a patch for gray with toners of CMY for each density region of an image for image formation, acquires a chromaticity value of the patch for gray, determines whether a chroma value obtained from the chromaticity value of the patch for gray for each density region is equal to or greater than a threshold value, generates, for a first density region corresponding to a patch with respect to which a chroma value determined to be neither equal to nor greater than the threshold value is obtained, using the obtained chroma value, a correction value for decreasing the chroma value, and generates, for a second density region corresponding to a patch with respect to which a chroma value determined to be equal to or greater than the threshold value is obtained, a correction value by performing interpolation calculation using the correction value generated for the first density region.
