ABSTRACT:
In a device for reproducing front MPEG 2 code a sequence of motion pictures, a slow-motion picture signal for N times slow motion playing is produced by combining the sequence of motion pictures reproduced and a plurality of interpolation picture sequences. Each of the interpolation picture sequences is interpolated between each one of the motion pictures and a succeeding one of the notion pictures. Each of the interpolation picture sequences comprises (n-1) interpolation pictures and in produced by calculating, from the motion vector data included in the MPEG 2, a motion vector between each one of the motion pictures and a succeeding one of the motion pictures, then calculating, from the motion vector, (n-1) interpolation motion vectors, and then producing the (n-1) interpolation pictures from the (n-1) interpolation vectors and the succeeding motion picture.
