Abstract
The present invention provides a playback apparatus for up-converting a video signal without magnifying film grains. An up-converter 5 performs up-conversion on a frame image in a video signal. A film grain detection circuit 6 detects film grains from the video signal. A frequency converter 7 converts spatial frequencies of the detected film grains on the video signal after the resolution conversion to high frequencies.
