Abstract

An image processing device includes; an image segmentation unit that divides an image information set into a plurality of image areas, the image information set forming a plurality of lines each constituted of colored pixels arrayed in a first direction, and the image information set expressing gradations forming an image as a number of the colored pixels existing in a predetermined image area; an image area shift unit that shifts the predetermined image area among the plurality of image areas in a second direction different from the first direction, relative to an image area substantially contiguous to the predetermined image area; and a pixel replacement unit that replaces the colored pixels forming part of each of the lines and existing within a predetermined distance range from the boundary, with at least one of the colored pixels intervening between the lines.

Description

technical field [0001] The present invention relates to an image processing device, an image forming device, and a program. Background technique [0002] A conventional image forming device according to an electrophotographic system forms an image on an image carrier such as a photosensitive element, and then transfers the image to a recording material. At the time of transfer, the positions of pixels forming an image and transferred to the recording material may be incorrectly transferred to positions deviated from desired positions. In order to overcome this problem in the technical field, various methods of correcting deviation of pixels by directly performing image processing on image data have been proposed. In one example of this method, a coordinate system is provided on which to position the image, relative to which the image is transformed to another coordinate system, and the image is adjusted by a correction amount to compensate for The location is off. [0003...
