ABSTRACT:
Moving pictures are reproduced from a stored moving-picture signal and output at a set reproduction speed. The stored moving-picture signal is reproduced in accordance with the set reproduction speed to obtain first interlaced pictures. The first interlaced pictures are converted to obtain first progressive pictures. Moving pictures to be displayed are selected from the first progressive pictures per frame in accordance with the set reproduction speed to obtain second progressive pictures. Scanning lines of the second progressive pictures are decimated so that the number of remaining scanning lines of the second progressive pictures after decimation is equal to the number of scanning lines of interlaced pictures to be displayed, thus outputting second interlaced pictures. The first interlaced pictures are output when the set reproduction speed is the first reproduction speed whereas the second interlaced pictures are output when the set reproduction speed is the second reproduction speed.
