PURPOSE:To minimize random noise by storing in a storing means an input video signal in synchronization with an input means, reading out the stored video signal data in synchronization with a recording means, and repeating the said operation plural times to record the same plural still pictures superposed on a picture recording medium. CONSTITUTION:A magnetic disk reading part 12 reads a video signal from a magnetic disk 10 in synchronization with a synchronizing signal generated by a reference generator 50. Then, an input synchronizing part 60 outputs a control signal to a storage part 26 through a switching part 58 in synchronization with a synchronizing signal separated in a synchronizing separator 18. A video signal from the part 18 is converted to a digital signal by an A/D converter 24, and sequentially written in the storage part 26. Meanwhile, an output synchronizing part 64 outputs a control signal to the part 26 through the switching part 58 in synchronization with the clock generated by the generator 50 so that a piece of a video signal data is read out from there. The said data is converted to an analog signal by a D/A converter 32, and recorded in a recording medium 56 via a recording part 54. The above said operation is repeated to record many sheets of one same picture are recorded in the same recording medium.
