Abstract: As to a telecine video signal (Sv), in a telecine video signal detector (Dtp) for detecting a scene-change part (SC) and deciding whether successive telecine conversion has been carried out, a motion detector (3) detects a motion between video signals (Sv) one field apart from each other; a first statistical processing unit (4) accumulates detection results (Sm) for one field; a first telecine decision unit (5) decides whether the field represents telecine-converted video; the second statistical processing unit (6) detects statistical information (Ss2) of the input signal (Sv); a scene-change detector (8) detects a scene-change in the output (Ss2) from the second statistical processing unit (6); a second telecine decision unit (9) decides field continuity from a detection result (Ssc) of the scene-change detector (8) and a result (St1) of the first decision unit (5); and then an AND circuit (10) carries out an AND operation on outputs (St1, St2) from the first and second decision units (5, 9).
