1. A method of converting light signals from a film into a video signal, the method comprising the steps of:

  • receiving a first signal, the first signal being generated responsive to a user control for a play speed of a film, the first signal including a plurality of first-signal pulses;

    receiving a second signal, the second signal being synchronized with a video camera that generates television signals, the second signal including a plurality of second-signal pulses;

    processing the first signal with the second signal, to generate a third signal, the third signal including a plurality of third-signal pulses, each third-signal pulse corresponding to a respective one of the first-signal pulses, each third-signal pulse being synchronized with a second-signal pulse, each first-signal pulse corresponding to a respective one of the third-signal pulses, whereby there is a one-to-one correspondence between the first signal pulses and the third signal pulses; and

    responsive to the third signal, moving a relative position of the film with respect to the video camera, to generate a video signal.
