Abstract
Whether a pixel in an image is included in a region with at least a predetermined number of lines is determined; with regard to a pixel that is determined to be included in the region with at least the predetermined number of lines, a pixel value is reduced at the same reduction rate whether the pixel is an edge portion or a non-edge portion, and with regard to a pixel that is determined to be included in a region in which the number of lines is smaller than the predetermined number, a pixel value is reduced in such a manner that a reduction rate is higher when the pixel is the non-edge portion than when the pixel is the edge portion.
