FIELD: television and computer equipment.
SUBSTANCE: invention relates to television and computer equipment and is intended for use in television cameras based on two single-chip sensors: "circular" and "rectangular" (matrix), made on the technology of complementary structures "metal-oxide-semiconductor" (CMOS). Result is achieved by means of an additional photodetector, which is a "rectangular" (matrix) sensor, while providing the same sensitivity of both photoelectric channels by means of light distribution of the input optical image of the monitored object through two channels, as a result of which on the first channel the image of each of m fragments of the monitored object is sequentially projected onto the target of the photodetector mounted on the electromechanical turret or on the guidance unit, and on second channel – image of whole "circular" frame is projected onto target of "circular" photodetector. At that, electromechanical turret or guidance unit performs circular spatial movement of matrix photodetector to one of positions, and to compensate optical loss of light distribution in the television camera, the gain Km of the active pixel is varied for each current "circular" line of the "circular" sensor. Such design of the camera provides generation of a digital video signal of a "circular" frame completely and separately of its selected fragment with high clarity, which provides for television-computer observation of objects having the shape of a circular ring. Disks, wheels, cutters, as well as other parts and accessories of multiple working and transport machines can be referred to similar objects (items) of industrial production.
EFFECT: high resolution of the separately observed fragments of the "circular" frame.
