An disclosed image processing apparatus reproduces an input pixel expressed by a gray level through a printing process performed on a plurality of segmented regions of the input pixel, based on an output pattern. The image processing apparatus includes: a duplicator configured to duplicate the input pixel into at least two pixels; a storage configured to store a plurality of tables, each of the plurality of tables associating the gray level and an output pattern of one of the duplicated pixels, such that a plurality of output patterns exist with respect to each gray level; and a controller configured to control a plurality of output regions, based on the output pattern corresponding to the gray level of the input pixel in accordance with a table selected for each of the duplicated pixels, the plurality of output regions corresponding to the plurality of segmented regions of each of the duplicated pixels.
