Abstract: An image processing device is configured to: generate a histogram of pixel values of a plurality of pixels contained in an image; set a background pixel value by using a peak value of the generated histogram; set a noise range with respect to the set background pixel value; and replace the pixel values that fall in the set noise range with a single arbitrary pixel value.
