Abstract

A method of producing a high resolution image includes generating high resolution image data for a high resolution image using a processor, wherein the high resolution image has a resolution higher than a resolution of an original image, determining image content of the high resolution image data, and selectively adding dither noise to the high resolution image data based upon the image content of the high resolution image data to produce final image data.
