FIELD: radio engineering, communication.SUBSTANCE: television camera includes a first digital television signal (DTS) sensor, a second DTS which is frequency- and phase-synchronised with the first DTS through a receiver synchronisation signal (RSS), as well as a multiplexer, wherein the photodetector target of the first DTS sensor is mated through a fibre-optic coupling with peripheral light guides with bundles of fibre-optic caps, and its central light guide bundles are matted with the photodetector target of the second DTS sensor, and operations for demultiplexing an input video signal and units for converting a "circular" frame into "rectangular" frames are performed in a server in a programmed manner.EFFECT: number of video signal sensors in the device, compared to the prototype, is reduced to two and enabling use of CCD arrays as photodetectors, said arrays having in the central region of the target, technological defects which cause white spot type image distortions.4 cl, 7 dwg |
