ABSTRACT:
A format converter has a memory capable of storing a video signal of progressive or interlaced scan construction and having one of a plurality of video data sizes and one of a plurality of frame rates, a frame rate controller using the memory to control a frame rate of the video signal, and a conversion filter for converting a video data size of the video signal. With the above configuration, conversion of the signal is effected without losing or detracting the features of the source material of the video signal. The conversion of the video data size is preferably effected on the output having the frame rate adjusted. With the above configuration, the format of a video signal can be converted without degrading the quality of the input video signal, and at the same time the required memory capacity can be reduced.
