摘要: An image processing apparatus includes an edge detector for detecting whether or not a target pixel of input signal is at portion discontinuous density image; first quantizer generating quantized data with respect to the by using error spreading filter having relatively high effect, such that between and output multilevel incorporated in "m" neighboring pixels surrounding pixel; second low selector selecting either generated accordance result detection made detector.
