Abstract
A video signal reproducing apparatus having a driving mechanism for driving a magnetic tape on which a video signal is recorded as succeeding video tracks and a transducing head device for reproducing the video signal from the succeeding video tracks mounted on a cylindrical drum around which the magnetic tape is wrapped, the transducing head device having a bimorph plate and a transducing head mounted thereon is disclosed. The apparatus includes a field memory for memorizing one field and two field previous video signals of the reproduced video signal, a comparator for comparing a field identification signal of a reference signal with that of the reproduced video signal, a selector for selectively deriving one of the one field and two field previous video signals in response to an output signal of the comparator, and adding circuit for adding at least two succeeding horizontal line signals of the reproduced video signal and for generating an averaging video signal, a detector for detecting the movement of the reproduced video signal in response to the reproduced video signal and the output signal of the memory, a weighting circuit for generating a weighting signal corresponding to the output signal of the detector, a circuit for weighting the output signals of the adding circuit and the driving circuit in response to the weighting signal and a circuit for combining the weighted output with the averaging video signal.
