Abstract

PURPOSE:To remove flickering of a picture, by discriminating that a moment when correlation between each field of a video signal has become weak is a time for converting a scene of a video signal, and controlling reverse and non-reverse operations. CONSTITUTION:A data of a video signal of each point is inputted to a buffer register 6 as soon as it is inputted to a register 4. From the register 4, a video signal data of the same point of 1 field before is outputted, values of a buffer register 5 and the buffer register 6 are checked by a coincidence detecting circuit 7, and in case of coincidence, ''1'' is added to a counter 9 through an AND gate 8 to which a strobe signal has been provided. Reverse and nonreverse states of a flip-flop circuit 13 are controlled by comparing an output of the counter 9 and a threshold level SH by a comparator 10.
