FIELD: video surveillance.
SUBSTANCE: invention relates to television and computer equipment and is oriented to the use in television camera of panoramic observation, which are made on the basis of "ring" television sensors on technology of charge coupled devices (CCD) and are designed to work in conditions when objects of control differ significantly from each other in terms of illumination and / or brightness. Result is achieved by the fact that the cameras provide simultaneously a surround-view of the situation in a region close to the hemisphere, i.e. in a spatial angle of 360 degrees in azimuth and tens of degrees in the elevation angle, while computer (server) operator evaluates the "sensitivity" of image of received k "rectangular" frames, and, according to this evaluation, sends a command to the television camera to form a new reference value of control voltage for ARVN and AGC in relation to selected corresponding section of "ring" target with low illumination (brightness), providing increased accumulation time of photodetector and an increased gain constant of video path of television camera for a new "ring" image frame.
EFFECT: technical result is increase in sensitivity of these separate "rectangular" frames recorded at low illumination (brightness) of the corresponding fragments of the panoramic image, by increasing the accumulation time of the photodetector and television camera video path gain factor for them.
