PPROBLEM TO BE SOLVED: To surely suppress generation of moire or a pattern disturbingg the view by means of simple methodology. PSOLUTION: A binarizing part for converting a multi-level image into a binary image is provided with: a pixel value acquiring part 13 for acquiring pixel values of pixels comprising the multi-level image; a sort part 14a for sorting the pixels comprising the multi-level image in order corresponding to their pixel values; a binarization processing part 15 for selecting a concerned pixel to be binarized according to the order sorted by the sort part 14a and binarizing a value of the concerned pixel; and an error diffusion part 16a for diffusing an error, which occurs in the binarization processing part 15 with the binarization of the concerned pixel, to non-binarized pixels around the concerned pixel.
