PURPOSE:To continue a horizontal synchronizing signal keeping the normal value of one horizontal scanning period, by providing a control means which controls the field interval of a video signal inputted to the delay means of a CCD delay circuit, etc. CONSTITUTION:At the time of reproducing a field, a motor 46 is rotated at speed lower a little than that at the time of recording. A field video signal outputted from a reproduction circuit 40 is inputted to a variable delay circuit 48. A sawtooth wave forming circuit 60 outputs a trailing signal by an inputted PG pulse signal. The oscillation frequency of a voltage controlled oscillation circuit 34 is controlled by the signal. The delay time of a shift register 54 rises from 0.5H to 1H at the time of inputting the PG pulse signal. Thereby, the interval of the horizontal synchronizing signal of a video signal outputted from the shift register 54 becomes 1H even at the start end of the field, thereby, the horizontal synchronizing signal is continued.
