摘要: One aspect of the invention provides a method halftoning an image which involves determining quantization error for selected target pixel image, selecting diffusion mask, mask relating to and pixels neighboring thereto, receiving first pair values including second pixel, third fourth pixel. The further ranking order first, second, by comparing pixels, diffusing at least one based on determined pixels.
