VIDEO TRANSFORMER OF OPTICAL EMISSION Russian patent published in 2005 - IPC

FIELD: multi-element matrix video transformers of optical radiation.

SUBSTANCE: device has matrix of photo-sensitive elements, connected by horizontal buses to vertical shift register and vertical buses - to cells of storage selection, which through all keys, connected to horizontal shift register, are connected through common video signal output bus to output pre-amplifier, while storage selection cell consists of communications transistor, connected by source to vertical buses, gate of which is connected to first control bus, and drain, via accumulation capacitance, - to power bus and to source of charge selection level transistor, gate of which is connected to second control bus, and source - to source of potential setting transistor, gate of transistor of source repeater and through storage capacitance - to power bus, source of potential setting transistor is connected to power bus, and gate - to third control bus, source of source repeater transistor is grounded, and source is connected to keys. In process of operation, transformation of charge packet to voltage is realized in a row of accumulating capacitances, to allow dropping of background component of charge and adjustment of non-linear component of transformation dependently on spectrum and brightness of objects emission, expanding functional capabilities, and perfecting contrast of image.

EFFECT: better image contrast, broader functional capabilities.
