摘要: In order to display a continuous tone colour image on discrete level display, methods of halftoning must be used. The high rate output devices means that serial real time are difficult use. A method and apparatus is disclosed for reducing the speed with which performed by performing an simultaneously dividing input into number areas individually making special provisions pixels located in boarder regions given area.
