Abstract
The present invention relates to error diffusion logic in which three partial diffusion error values are produced in a pipelined manner and then summed together when the last partial error value is produced. The resulting summed error can be used to adjust a target pixel in a sequence of pixels or stored in a buffer until further corresponding partial error is produced for adjusting the target pixel.
