IMAGE STABILIZATION CIRCUIT FOR TV SET WITH HALF-WIDTH SCREEN

摘要

FIELD: television technology. SUBSTANCE: image stabilization circuit for TV set with half-width screen is supplemented with detector detecting variations of high voltage in secondary winding of transformer of beam flyback and generating signal corresponding to variations of mentioned high voltage and with adder summing up output signal detected by detector with " west/east " signal. EFFECT: prevention of bending of vertical image lines by detection and compensation for variations of high voltage caused by change of image brightness. 2 cl, 8 dwg
