Abstract
An image processing device includes a first output unit that performs predetermined image processing for image data, and outputs image data having m bits per pixel; a second output unit that performs pseudo gradation-increase processing by a dither method or a multilevel error diffusion method for the output image data, and outputs image data having n bits per pixel, where n<m; and a compression unit that compresses the output image data. When a dither matrix for the dither method or a filter for the multilevel error diffusion method used by the second output unit for the pseudo gradation-increase processing is divided into plural pixel groups each including plural adjacent pixels and when each pixel group serves as a unit, processing parameters respectively set for pixels in the same pixel group are similar as compared with processing parameters respectively set for pixels in different pixel groups.
