FIELD: radio engineering, communication.
SUBSTANCE: method involves forced "long" and "short" accumulation of signal charges in adjacent frames (half-frames) in the photodetector of a television camera; generating a multiplex image signal at the output of the photodetector; generating, at the "video" output of the television camera, a multiplex television signal which is transmitted to the "video" input of a personal computer; the computer demultiplexing the video signal by delaying the input multiplex television signal by a frame (half-frame) and performing weighted summation of the forward and delayed video signals through remote sampling from the computer for that delayed component of the video signal with optimum duration of "short" exposure of the CCD array in the television camera.
EFFECT: high accuracy of recursive filtering by doing away with light splitting while facilitating adjustment of the degree of filtration by controlling the accumulation time of the delayed component of the output video signal.
