2. Description of the Related Art A video signal representing a subject image taken by a movie video camera is recorded and stored, for example, on a magnetic tape. The video signal recorded on the magnetic tape is read and reproduced by a reproducing device, so that a subject image is displayed on a television device connected to the reproducing device. There is also a reproducing device to which a printer device can be connected.
