Abstract
An error diffusion technique seeks to remove artifacts resulting from the diffusion of large errors. This technique removes artifacts resulting from instances where there is little difference between a source color and a target color but there is a large diffused error component. The error diffusion technique clips a combination vector resulting from the combination of a source color with the diffused error component so that the combination vector extends roughly one quarter of the width of a color gamut beyond the boundary of the color gamut. This helps to prevent ever-increasing error vectors and, thus, helps prevent certain artifacts in images that are output.
