ABSTRACT:
In a still video device, a high definition image signal corresponding to one frame is passed through a low-pass filter with a cut-off frequency f.sub.ch, divided into "m" of parts, and stored in a memory at a sampling frequency f.sub.sh. The horizontal scanning frequency of the high definition image signal is f.sub.hh, and the horizontal effective period ratio of the high definition image signal is e.sub.hh. The image signal is read out from the memory at a sampling frequency f.sub.sn so that the image signal is time-expanded to be transformed to a normal image signal, which is passed through a low-pass filter with a cut-off frequency f.sub.cn. The horizontal scanning frequency of the normal image signal is f.sub.hn, and the horizontal effective period ratio of the normal image signal is e.sub.hn. The parameters satisfy the following relationships,
