Dithering is a technique for representing continuous tone images using a limited palette of colors. Different shades of gray or color are replaced by patterns of pixels whose color approximates that of the original image. For example, dithering is often used to display 24-bit color images on a display adapter that can only display
There are many different dithering techniques, each of which has its own distinctive appearance. Some of the most common dithering techniques are ordered dither and error diffusion. The following examples show how a continuous tone image that varies smoothly from black to white can be approximated using only black and white pixels.
