PHN.7953 29.12.75 ABSTRACT: When the information of a continuous-motion video record is displayed in the stop-motion mode by repeated display of two fields which form an interlaced picture, motion in the scene gives rise to a frame- frequency flicker phenomenon in the stop-motion picture. By forming suitable video signal combinations in discrete groups which each comprise two associated fields and by recording these combinations in the video record, the flicker phenomenon in a stop-motion picture is eliminated without continuous display being perceptibly affected.
