ABSTRACT:
The magnification ratio of image information carried on an original is changed for reproduction at a desired magnification ratio. The size of the image information is reduced or enlarged to a prescribed size by an optical system. Thereafter, the image information is photoelectrically converted by a light sensor. The photoelectrically converted image information is selectively picked up or data between adjacent items of the photoelectrically converted image information is determined by interpolation, thereby obtaining image information at a desired size.
