Apparatus for detecting noise in a color video signal |
摘要 |
A phase detector provides angular phase error measurements of the color burst component of a video input signal. Burst phase errors exceeding a given angular threshold are detected and the number occurring within a given period of time are counted. From the accumulated count, a noise indicating signal is derived and applied to a video picture processor for controlling a parameter of displayed images.
