IPC: H04N5/937
Filed: 1997-05-15
Abstract: PROBLEM TO BE SOLVED: To cope with the difference between the field frequency of a video signal on an inputting side and the field frequency of a video signal on an outputting side, also to decrease the frames of an input video signal and to read the same video signal several times continuously. SOLUTION: A video signal is written in a field memory 101 in a timing based on a video signal on inputting side and read in a timing of a reference signal. A mask signal generation circuit 112 generates a mask signal MA1 based on a period decreasing the frames. A mask signal generation circuit 113 generates a mask signal MA2 based on a transition period of a field of a video signal to be outputted. A mask signal MA3 which is formed from the signals MA1 and MA2 based on a video signal on the read side masks a control signal on a write side. This operation makes it possible to decrease the frames, to prevent write from occurring in the transition period of a field of a video signal to be outputted and to prevent the passing of a read address and a write address from taking place.
