PURPOSE:To reproduce a picture with the high dignity and in the high detail by controlling the mixing ratio of the output of a smoothing means and the output of an edge emphasizing means by the output of an edge detecting means, concerning the picture processing device of a copying machine, facsimile equipment, etc. CONSTITUTION:An edge emphasizing part 302 corresponding to an edge emphasizing device (b) executes the output of an edge quantity (edge detection) detecting part 5 and executes the multifying of a control signal S9 with a multiplier 6. When the attention picture element of the picture processing is assumed as A, by an adder 7, the certain coefficient-fold value of an attention picture element and an edge detection is added, and the attention picture element is emphasized by the edge. In a mixing part 305, at the circuit to mix the output of the edge emphasizing part 302 and the output of a smoothing processing 3 by the suitable ratio, S3 and S4 are outputted in accordance with the output of a differential value detecting part 1 inputted to the front step control signal generating part 2. |
