ABSTRACT:
In order to display continuous tone colour image on a discrete colour level display, methods of halftoning must be used. The high display rate of colour output devices means that serial methods of real time halftoning are difficult to use. A method and apparatus are disclosed for reducing the speed with which a halftoning method must be performed by performing the halftoning of an output image in parallel by simultaneously error diffusing more than one line of input at a time.
