PURPOSE:To obtain a picture with high quality regardless of the presence of nesting by deciding whether or not a constituting picture element such as a character is a constituting picture element such as a photograph at each picture element and applying a picture processing corresponding to each picture element depending on the result of decision so as to apply the picture processing of an original where a binary picture and a multi-value picture exist in mixture. CONSTITUTION:A picture processing unit 13 reads sequentially picture information of each picture element from a line buffer 12 under the control of a microcomputer 15 in parallel with the write of picture information to the line buffer 12 and applies a prescribed processing. When a deciding section 133 decides the picture element as a character constituting picture element, a multi-grading processing section 135 applies multi-grading processing and supplies an output. A picture output device 14 is such a device as a printer or a CRT display and prints out or displays a processed picture signal outputted sequentially from the picture processing unit 13 in parallel with the read of the picture reader 11.
