- Present participle of dither.
dithering - Computer Definition
Causing a displayed or printed image to appear more photographic by inserting shades of gray or color. Dithering simulates more colors and shades in a palette than actually exist. While dithering cannot produce the identical results as having sufficient levels of gray or colors in the graphics display system (the bit depth), it can make shaded drawings and photographs appear extremely realistic. See 24-bit color and halftone. Dithering is also widely used to smooth curves and diagonals (see anti-aliasing).
