LINE FLICKER SUPPRESSION BY ADAPTIVE DE-INTERLACING

摘要

A television display system employing edge brightness flicker reduction by modulation of the vertical deflection signal has digital control words for modulation polarity (D) and magnitude (S). These digital words are coupled to an amplifier (900) and converted to a bipolar analog signal (Bp). The bipolar analog signal (Bp) comprises values in a first and second range. Signals in the first range produce vertical deflection modulation in a first direction and signals in the second range produce vertical deflection modulation in the opposite direction.
