Abstract

PURPOSE:To enable the switching so that optimum binarization can be applied every character field, by the picture memory storing the scanning data toward row direction read in on the document. CONSTITUTION:The preprocessing circuit 7 consists of the address counter 12 and ROM12, and to ROM12, the binarized system applied at the character field corresponding to the boundary address of the character field is stored. The content of picture memory is read out according to the scanning line with the address of the address counter 11 and given to the binary circuit 8. Further, at the address of the boundary of character field, the switching of binary system is made. Thus, the binary output is obtained with the character pattern from the picture memory 6 and the system data of binarization from ROM12 at the binary circuit 8, and it is stored in the memory 13.
