Abstract

PURPOSE: To process an original even with one reading without losing the property of the original by providing a means designating a desired area of the original and a means designating a data form of the designated area and other area so as to read an original based on the corresponding data form and the area.
CONSTITUTION: Most part of an original is a binary picture area P1 and an intermediate picture area P2 exists therein. The area designation is applied by giving data y1, l1, l2 to a counter (not shown). In scanning the area P1, a CPU 12 outputs a binary data selection signal and outputs a pseudo halftone data selection signal in scanning the area P2. A selector circuit 15 selects an output of a binary circuit 7 at the data selection signal output and an output of a dither conversion circuit 6 at the output of a pseudo halftone data selection signal output in response to a binary data/pseudo halftone data selection signal outputted from the CPU 12. Thus, as the data of one line, a multi-value data (pseudo halftone data) is outputted in mixture in the binary data.
