Abstract
A television monitor display with video signal processing comprises a source (SM) of a video display signal (Y) including a sync component (S). A video processor (U1) is coupled to process the video display signal (Y). A sync separator (SS) is coupled to generate separated synchronizing signals (Sy) from the sync component (S) of the video display signal (Y). A video amplifier (100) is coupled to the sync separator (SS) and the video processor (U1) and generates an output video signal (Ys+) wherein a sync component (S+) of the output video signal is increased in amplitude in accordance with the separate synchronizing signals (Sy) coupled to the video amplifier (100).
Claims7
A television monitor display with video signal processing, comprising:
- a source of a video display signal with a sync pulse component;
- a video processor coupled to process said video display signal and form an output signal with said sync pulse component increased in amplitude relative to other components of said video display signal;
- a sync amplitude clipper coupled to said video processor and clipping said increased amplitude sync pulses to a predetermined value;
- a controller coupled to provide one of enabled and disabled operation of said sync amplitude clipper, wherein said controller enables clipping to form said output signal with said predetermined amplitude value, and wherein said controller disables clipping and allows said output signal to retain said increased sync pulse amplitude component.
