Abstract
PURPOSE: To automatically match a music to the movement of an animation by extracting a prescribed video element from video information and detecting the periodicity of the change of this video element and controlling the playing tempo in accordance with this period. CONSTITUTION: A video signal input device 1 to which a video signal as video information is inputted, a picture processing circuit 2, a change extraction circuit 3, a microprocessor 4, etc., are provided, and the prescribed video element is extracted from video information, and the periodicity of the change of this video element is detected, and the playing tempo of an automatic player is controlled in accordance with this period. Thus, music is automatically played at a tempo corresponding to the period of the change of the video element. Especially, when background video used in a dance, a discotheque, or the like is taken as video information, music is played or produced at a good tempo corresponding to the change of video.
