ABSTRACT:
To display a more natural display screen without sense of strangeness, when displaying a video signal having a greater number of horizontal scanning lines than the number of horizontal display lines of the display means. The video signal is displayed by thinning at a rate of one out of every plurality of video signal groups. Accordingly, missing of only upper and lower portions of the video signals of the display screen is prevented, and when the video signal is compressed and displayed, a natural display screen without sense of strangeness is presented.
