Abstract
There is provided an image processing apparatus having an image segmentation unit that divides image formation into image areas in a first direction, a random number memory that stores random numbers, a reference position determination unit that determines a reference position so as to vary in a second direction perpendicular to the first direction, a pixel determination unit that determines a pixel as a target to be subjected to correction processing of pixel insertion into or pixel reduction from each of the image areas, for the each of the image areas, according to the stored random numbers and the determined reference position, among pixels in the each of the image areas, and an image width change unit that performs the correction processing on the determined pixel to change an image width of the image information in the first direction.
