PURPOSE:To realize the picture processor in which a binarizing circuit applying proper binarization processing to a picture with a binary picture and an intermediate tone picture are in existence in mixture respectively is realized with a simple hardware configuration with respect to the picture processor. CONSTITUTION:A matrix forming circuit 11 forms a matrix data from an input picture element signal, a block area discrimination circuit 21 discriminates a picture area from a picture element level under consideration from a matrix data, and a selection circuit 23 selects and outputs a fixed binarization picture signal outputted from a fixed threshold level binarizing circuit 14 as an output binarized picture signal in the case of a character picture area, a multi-stage binarizing picture signal by a smoothing matrix data outputted from a dither processing circuit A15 in the case of a dot picture area is selected and outputted as an output binarizing picture signal and the multi-stage binarizing picture signal by the matrix data outputted from a dither processing circuit B16 is selected and outputted as an output binarizing picture signal in the case of an intermediate tone picture area. |
