ABSTRACT:
An acoustic control apparatus which can be applied to an electronic musical instrument controls the acoustics of a musical tone to be generated in response to variation of an image. In order to detect the variation of an image, the acoustic control apparatus extracts a predetermined image element from image information to be given thereto. This image element can be identified as movement of an image, color of image or an outline of image. The color of an image can be detected by detecting hue and/or number of colors in the image. In addition, in response to periodicity in variation of this image element, a performance tempo of musical tone can be controlled.
