ABSTRACT:
In an image signal recording and reproducing system, a phase reference signal, the phase of which is synchronized with the phase of an image signal, is added to the image signal in a recording mode so as to be recorded on a recording medium, while the phase of a sampling signal for sampling a reproduced image signal is controlled by using the phase reference signal separated from the reproduced signal in a reproducing mode, whereby the image signal can be accurately sampled without an influence from a time variation change in the reproducing side.
