ABSTRACT:
There is provided an optical image processor for forming a charge image according to a first optical image by photoelectric effect when illuminated with an electro-magnetic radiation beam for writing carrying the first optical image and forming, in accordance with the charge image, a second optical image correlating with the first optical image by light-modulation when illuminated with an electro-magnetic radiation beam for reading, in the presence of an electric field. The processor comprises a plurality of photoconductive segments two-dimensionally arranged with a space among the photoconductive segments for forming the charge image when illuminated with the electro-magnetic radiation beam for writing and a high resistive member provided in the space for preventing transfer of electric charges of the formed charge image among the photoconductive segments.
