Discloses an image formation apparatus capable of achieving a picture quality improvement of a multi-value image without increasing the size of a look-up table to a size larger than the size of a look-up table that is used for the picture quality improvement at the time of forming two-value image data. The image formation apparatus can form an image having at least one density in addition to two values of white and black in pixel units, and includes a density separation section that distributes a multi-value image data to a plurality of density planes according to a predetermined rule, a correction signal generator that outputs correction signals for correcting the layout of pixels in each of the plurality of density planes, and a correction signal combiner that combines the correction signals output from the density planes according to a predetermined combining rule. |
