A parallel optical image processing system comprises a image detection part for detecting an input image, an encoding part supplied with an electrical image signal from the image detection part for producing an encoded input image in a form of optical beam, an optical memory stored with a number of images in a form of encoded image, an optical interconnection part supplied with the encoded input image for addressing the optical memory by deflecting the optical beam so as to read out one of the images stored in the optical memory as an associated image, a first optical path supplied with the encoded input image, a second optical path supplied with the associated image, a decoding part supplied with the encoded input image and the associated image from said first and second optical paths as an encoded output image for decoding the encoded output image thus supplied to form a decoded output image, and feedback control part for controlling the addressing of the memory by the optical interconnection part responsive to the encoded output image.
