ABSTRACT:
An image scanning section has an optical system for scanning an original in a two-dimensional manner, and a photoelectric converter for converting an optical image obtained by the optical system into an electrical signal. A binary coding section performs simple binary coding of the electrical signal supplied from the photoelectric converter in such a manner as not to accompany pseudo-gray scale coding, and performs pseudo-gray scale binary coding of the electrical signal supplied from the photoelectric converter in such a manner as to accompany pseudo-gray scale coding. An area designating section designates an area on the original. A scanning mode designating section designates image scanning modes within and outside an area designated by the area designating section and has at least a first scanning mode designating section which does not accompany pseudo-gray scale coding and a second scanning mode designating section which accompanies pseudo-gray scale coding. A controller controls an output or outputs from the binary coding section in accordance with designation by the area and mode designating sections.
