Abstract
A resolution converting method for converting a resolution of a binary image to an integral multiple resolution, includes: representing a density of an arbitrary position of the input image as an interpolation value; overlapping the output image on the input image in a setting that a pixel of an edge section of the output image is shifted by a minutely small quantity from a pixel position of the input image in a horizontal direction and a vertical direction; and allotting an area of a pixel to each pixel of an output image which overlaps an area of the input image, integrating interpolation values of the area of the input image, normalizing an value obtained by the integrating the area of the pixel, and determining a binary data.
