Abstract
An image processing apparatus includes a light modulator, an analog writing system for analogously writing an image of an original in the light modulator, a digital reading system for digitally reading the written image out of the light modulator, a processing section for processing the read image data, a digital writing system for digitally writing the processed image in the light modulator, and an analog reading system for analogously reading the image written on the light modulator. The light modulator includes a photoconductive material, a liquid crystal layer laminated on the photoconductive material, and a pair of electrodes sandwiching the photoconductive material and the liquid crystal layer. The liquid crystal layer can provide a storage function so as to enable the reading and writing of the image from the same direction.
