METHOD OF FORMING VIDEOSIGNAL IN "RING" PHOTODETECTOR FOR COMPUTER SYSTEM OF PANORAMIC TELEVISION SURVEILLANCE Russian patent published in 2017 - IPC H04N5/335 

Abstract RU 2611424 C1

FIELD: physics.

SUBSTANCE: invention relates to the panoramic television surveillance, which is carried out by the computer system with the television camera of all-round view in the area similar to a hemisphere, i.e. in the spatial angle of 360 degrees in azimuth and tens of degrees in the elevation angle. The area of the reading aperture is controlled in the process of obtaining the image signal due to the fact that, from line to line, the duration of the control pulses (reset pulses) is changed for the "charge - voltage" transducer unit (TUCV).

EFFECT: increasing sensitivity of the "ring" photodetector on the field in the radial direction toward its outer periphery by proportional increasing the aperture area.
