ABSTRACT:
An image processing method of the invention is used for dividing each pixel of binary image data into pixels, with of the pixels having a size smaller than each pixel of the binary image data. The image processing method includes the steps of (a) referring to a first white/black pattern formed by a first group of pixels next to a pixel of interest that is a subject of image processing; (b) referring a second white/black pattern formed by a second group of pixels next to the first group of pixels; (c) dividing the pixel of interest into divided pixels; and (d) determining colors of the divided pixels on the basis of the first white/black pattern and/or the second white/black pattern so that an image formed by the divided pixels has a smoothed slant portion or jagged portion.
