We propose error diffusion based on threshold control using fuzzy inference. In the proposed method, the same black or white pixels along a periphery that lowers image quality, is decreased without loss of edge enhancement using threshold control. We applied the method to standard digital images and confirmed that the method is superior to the conventional.
