Abstract
A non-causal error diffusion technique that is capable of gray image signals into binary image signals to prevent the occurrence of visible correlated patterns and/or artifacts. In the non-causal error diffusion method, transformation errors produced when great gray level sets of image signals for a certain pixel are transformed into reduced gray level sets of image signals are reflected to the image signals for pixels at non-causal locations with respect to the certain pixel.
