Abstract

PURPOSE: To eliminate the jump by obtaining the reproduction signal with each field, featuring four sets of signals fundamentally, with the signal loss or gain featuring the specified interval, thus obtaining the still slow motion free from skew or the like.
CONSTITUTION: Auxilizry heads a1 and a2 are provided on drum D with the angular gain given by 0.25H to a2, and each output is drawn out via switch SW1, delat line DL1 equivalent to 0.5H and SW2 each. Thus the slow motion reproduction can be performed with 1/3 speed and in the 4-cycle type capable of reproduction with every field, where Tf shows one-field time (262.5H) of reproeuction in the normal time, and Ts1 shows one cycle at the 1/3-speed slow motion reproduction each. On the other hand, SW2 gives 1/2-frame delay DL2 to the output of pulse oscillator OSC with 1/2 division given by the FF. And the switching is given with output (a) and (b). Accordingly, the relative position between a1 and a2 is shifted by 0.25H to 180, and furthermore the reproduction signal equivalent to one frame is delayed by 0.5H. As a result, no jump is caused to the signal of output terminal o.
