<p>In a video signal reproducing apparatus having a field memory for still picture reproduction, the period Ti of reading a still picture signal from the field memory is altered to different lengths of time to repeat the reading operation for the different periods as one cycle. The sum of the reading periods Ti within one cycle is equal to the vertical synchronizing signal period Tv times an integer. Each of the reading periods Ti is set to a value equal to the period Tc of color subcarrier times an integer, approximate to the horizontal synchronizing signal period Th times an integer to the greatest possible extent and approximate to the vertical synchronizing signal period Tv to the greatest possible extent. Accordingly, there is no disturbance in the color subcarrier period at the function between fields, while the disturbance in the horizontal synchronizing signal period at the field junction can be greatly diminished.</p> |
