FIELD: radio engineering, communication.

SUBSTANCE: apparatus for performing space-time image processing based on photosensitive charge coupled device matrices, having an optical system which is the input of the apparatus, a light metre, two beam choppers, a control device, a subtractor, two units of photosensitive charge coupled device, a mutual displacement device (MDD) for the projected scene image and image sensors (PCCD-1, PCCD-2 and light metre), a beam-splitting system (BSS), wherein the output of the optical system is optically connected to the input of the MDD, the electrical input of the MDD is connected to the first output of the control device, the optical output of the MDD is connected to the optical input of the BSS, the first output of the BSS is optically connected to the input of the first beam chopper, the second output of the BSS is optically connected to the input of the light metre, the third output of the BSS is optically connected to the input of the second beam chopper, the electrical output of the light metre is connected to the input of the control device, electrical inputs of the beam choppers are connected to second and third outputs of the control device, the output of the first beam chopper is optically connected to the input of the unit of photosensitive charge coupled devices PCCD-1, the output of the second beam chopper is optically connected to the input of the second unit of photosensitive charge coupled devices PCCD-2. Electrical inputs of the first and second units of photosensitive charge coupled devices PCCD-1 (FN_I1,2,3, FP_I1,2,3, FR_I1,2,3, FN_II1,2,3, FP_II1,2,3, FR_II1,2,3) are connected to four outputs of the control device. Outputs of the first and second units of photosensitive charge coupled devices are electrically connected to the first and second inputs of the subtractor, the electrical output of which is the output of the apparatus for space-time image processing based on photosensitive charge coupled device matrices, which generates the output signal.

EFFECT: eliminating disruptions in adapting the apparatus to change in the level of illumination when selecting moving objects and, consequently, increasing the probability of selecting moving objects on a non-stationary background, and eliminating distortion of processing results associated with overflow of potential wells of photosensitive charge coupled device matrices.
