摘要
A method and system implements selective, memory efficient, control over the amount of error diffused in a hybrid screening system. An image context error computer receives a pixel classification and an error value. Upon receiving these data, a set of shift registers supplies a fractional portion of the error value to an error diffusion circuit. A bypass thresholder receives screened video and applies simple thresholding. In parallel with the simple thresholding, an error diffuser receives screened video and applies error diffusion. The results of the two processes are output to a multiplexer which outputs one based on the pixel classification.
