Abstract
A video signal producing system includes an imaging device for obtaining progressive imaging signals having various frame rates, a recording device for recording an output signal of the imaging device and a reproduction device for reproducing a recording signal obtained from the recording device. The imaging device includes a frame rate converting portion for converting the imaging signals to an output having a predetermined frame rate and the reproduction device changes a reproduction speed in response to each of the various frame rates so as to generate an output having a substantial number of frames such that the substantial number of the frames assumes a predetermined value.
