Abstract: FIELD: computer engineering. 
     SUBSTANCE: instantaneous object recognition computer system is made with possible recording, storage, erasing, reproduction and recognition of information, and includes a computer, device for controlling electronic devices, controlled by computer, memorizing-recognizing block of memory pages, input contacts of which are connected to device for controlling electronic devices controlled by computer, and output contacts are connected to reading device of the computer. Memorizing-recognizing block consists of memory pages in the form of board with thyristor-stabilitron cells. Controlling electrodes of each thyristor of thyristor-stabilitron cell memory pages are connected to analogical controlling electrodes of adjacent memory pages, creating a system of input contacts of memorizing-recognizing device. Output contacts of stabilitron circuits of thyristor-stabilitron cells are connected to analogical output contacts of stabilitron chains of adjacent memory pages, creating a system of output contacts. The principle of memorization and instantaneous recognition includes outputting the normalized contour, which should be memorized in memorizing-recognizing block, to a monitor screen. Computer calculates the contour of thyristors which should be opened on given memory page in such a way that contour of electric current passing through these thyristors on memory page forming an electric circuit, is analogical to image contour on monitor screen, which signifies memorization and is stored in memory until current electric circuit is killed on signal from the computer. For opening these thyristors the device for controlling electronic devices controlled by computer dispatches opening control impulses to input contacts of memorizing-recognizing device, connected to controlling electrodes of memory page thyristors, contour of which matches the contour of the image being memorized. For recognition of object on basis of contour of its normalized image or only by its fragment, outputted on the monitor screen, the computer determines coordinates of input contacts of memorizing-recognizing block, corresponding to contour of the object being recognized, and dispatches control impulses to them. For more precise recognition of object on basis of its fragment the computer creates a system of moveable buses, which select a part of contour of template images in accordance to which recognition is performed. On the memory page on which the contour of electric current passing through thyristors of thyristor-stabilitron cell of contour of memorized template image coincides with contour of the object being recognized, the current, passing along contour of thyristor-stabilitron cell, is increased, resulting in disruption of stabilitron chains of thyristor-stabilitron cell and appearance of potential on output contacts of memorizing-recognizing block, contour of which is analogical to the contour of the object being recognized. The computer, reading the contour of output contacts of recognizing-memorizing block with potential, outputs the contour of recognized image - template image to monitor screen together with information about it or sends recognition signal to executing organ. 
     EFFECT: increased trustworthiness of recognition, expanded recognition capabilities.
