摘要 |
A jitter detector (22) for detecting jitter in a video signal (Sv) measures the vertical time (Stf(v)) of one field (v) of a video signal (Sv) to judge based on a vertical time signal (stf(v)) whether the video signal (Sv) jitters or not. When the number of continuous judgments (Cej) that the video signal (Sv) jitters is smaller than a first prescribed number (Tej), the video signal (Sv) is judged to be a jitter signal (Svj). When the number of judgments (Cnj) that the video signal (Sv) does not jitter is smaller than a second prescribed number (Tnj), the video signal (Sv) is judged to be a non-jitter signal (Svjn).
