Abstract

PURPOSE: To zoom automatically a camera lens according to contents of reproducing video by a constitution where the object image from the camera are synthesized in the reproducing picture of a VTR and the picture is recorded by another VTR.
CONSTITUTION: During the vertical blanking period of video signals, reproducing signals of VTR1 where a key code according to contents of a background picture is recorded are supplied to key code detection and decode circuit 11. In circuit 11, reproducing signals are supplied to gate circuit 14 as well as vertical synchronizing separator circuit 12, and vertical synchronizing signals PV are taken out to obtain key code signals. These signals are applied to D/A converter 15, and pulse voltage EA corresponding to code information is supplied to peak hold circuit 16 to obtain voltage EH where voltage EA is held. This voltage is supplied to motor 18 through drive circuit 17, and motor 18 is rotated by a quantity correspondint to this voltage value. Thus, zooming corresponding to the background picture is performed automatically, and unnaturalness of synthesized video is eliminated to obtain good video.
