摘要: A picture flicker correction is desired with video disc players involving display of a stop-motion or still television and displays using field line frequency doubling, in accordance the so-called ABAB method. With movement detector (51) absence detected. Two adding circuits (19, 22) are connected parallel to delay devices (9, 9+12) having time delays substantially equal period. By means two switch-over (32, 37) switched by (51), can be coupled device (45) which once per further (42) period provides for information transfer during second periods frame comprising periods. In detection, original transferred, event combined transferred.
