摘要： A television reproducer for a movie film (cine film) which has a device for flashing in synchronism with a detected frame signal. The frame signal indicates the position of a frame of a continuously fed movie film. A vidicon device scans vertically a plurality of fields within a flash duration with a scan frequency of 60 fields per second of a standard television system. The scanning frequency is obtained from the frame signal. The reproducer also includes a circuit for varying the amplification degree of video signals in synchronization with the frame signal for preventing flickers. Thus, the film may be projected to the television without any special devices.
