Abstract
A process discriminating unit allows an optimum converting process among a first magnification processing unit, a second magnification processing unit, a first reduction processing unit, a second reduction processing unit, and a third reduction processing unit to be executed on the basis of a conversion magnification (K), a resolution (D), and an image size. Particularly, each of the second magnification processing unit, first reduction processing unit, and second reduction processing unit magnifies an original image to a virtual image of a dot size obtained by magnifying a target image by 2 or 4 by an interpolation based on a simple repetition by a nearest neighborhood method and, after that, reduces to the target image in which the pixel value is obtained by averaging a plurality of pixels corresponding to one target pixel of the virtual image.
