ABSTRACT:
A system for recording a video signal derived from a solid state image sensing device including a number of picture cells is disclosed. The video signal is read-out of the solid state image sensing device and is recorded on a magnetic tape of a video tape recording device. When a shutter release button is pushed, the magnetic tape is rewound by a given length and then the magnetic tape is traveled forward. During the forward movement of the magnetic tape, the video tape recording device is set into a reproduction mode and the video signal which has been previously recorded is reproduced. As soon as the video signal is not detected from the magnetic tape, the video tape recording device is changed into a record mode and after a given servo lock time, a shutter is opened for a given period. Immediately after the shutter is closed again, the video signal is read-out of the solid state image sensing device and then is recorded on the magnetic tape which is traveled at a given constant speed.
