Correlation processing is used effectively with signal/image processing in the field of computer vision and remote sensing from satellites. Therefore, correlation processing is a promising area of image analysis and recognition, as for huge amounts of video information the automation with high-speed image processing is required. The need for high-speed processing of large amounts of optical information, including video signals, requires a comprehensive approach to the input and output of information in a human-friendly way, and the using of powerful digital methods for the correlation processing of digitized images. Therefore, the purpose of this work is to improve the process of digital correlation image processing in optoelectronic system with the ability to visualize the results of correlation processing. This paper presents a structur of optoelectronic system based on a correlation matrix with a toroidal topology of connections between its computational cells. Features of functioning of optoelectronic system are considered and two examples of correlation processing of binary images are given. The reduction of functional load on the computational cells in the correlation matrix allows to use the digital correlation methods, and the conversion of the input optical image into a digital two-dimensional binary, with subsequent presentation of the result of the correlation processing as the optical two-dimensional signal are realized respectively on the integrated analog-to-digital converter and LED matrix. Orientation to the normalized correlation processing allows, first, to obtain a binary correlation relief with a corresponding decrease in the hardware costs of the computational cells of the correlation matrix, and second, to realize the visualization of the binary correlation relief with the using of an LED matrix
