Abstract

PURPOSE: To impart subtle, various, or special changes to performance by providing an image pickup means, a distance measuring means a video element extraction means, and an acoustic control means. CONSTITUTION: A TV camera 1 with an auto-focusing device, a video element detection circuit 2, a distance detection circuit 3, a music control circuit 4, etc., are provided, The video element detection circuit 2 detects an area ratio to the video background and the hue and the outline of an AF area (object) from a video signal of the TV camera 1 and sends them to the music control circuit 4. The distance detection circuit 3 detects the distance of the AF area, and the music control circuit 4 operates control parameter data corresponding to video element detection information outputted from the video element detection circuit 2 and changes the equalizer, the reverberation, the acoustic field effect, the tone color, the sound volume, etc., of acoustic information in accordance with these distance and video element. Thus, music is expressed correspondingly to video, for example, the distance is musically sensed, and performance with subtle, various, or special changes is realized.
