FIELD: electronic equipment.
SUBSTANCE: invention relates to television equipment and is intended for use in television cameras made on the basis of matrix television sensors based on the technology of charge coupled devices (CCD), in which electronic adjustment of sensitivity is provided due to change of intraframe accumulation time. Result is achieved by the fact that in output register of shift of CCD matrix frequency of element-by-element transfer of charge packets ƒe reduced twice and output shift register is made in the form of two adjacent linear registers acting alternately on the first two-channel CVMB in one direction or on the second two-channel CVMB in the opposite direction, wherein each of said linear registers comprises half the elements of the number of pixels for each photodetector row, and to optimize the selection of the accumulation mode of the CCD matrix, spatial rotation of the photoreceiver around the center point of its target is performed through angle of 90° (clockwise), changing the spatial position of the target from "landscape" to "book", generating a composite video signal "video 1" or "video 2" in accordance with two spatial positions of the CCD matrix. Operation of the television camera, recording of its video signal and reproduction thereof are carried out using computers combined into a local computer network.
EFFECT: high sensitivity for fragments of the monitored image by increasing accumulation time for them during parallel arrangement of selection of their spatial position and with computer reconstruction of the formed image, as well as simultaneous implementation of saving power consumption of the photodetector.
