Method and apparatus for minimizing artifacts in images produced by error diffusion halftoning utilizing ink reduction processing

摘要

An image processing method and apparatus processes image data line-by-line using an error diffusion or dithering process to generate a halftoned image in which the radius of a dot representing a pixel is 1/dpi</=r</= 2ROOT 2/dpi. The method and apparatus selectively performs the halftone process on every other pixel to reduce in consumption and computation time while maintaining a high resolution. <IMAGE>
