Dividing one of input gradations and output gradations of gradation characteristics, indicating input/output gradation characteristics reproduced in a second conversion unit, into gradation segments having predetermined gradation intervals. Then, correcting each of the gradation values of the other gradations of the gradation characteristics so that gradation intervals of the other gradations become intervals corresponding to the predetermined gradation intervals. The first conversion unit then converts the gradation values of an image using the corrected gradation values.
