摘要：PROBLEM TO BE SOLVED: To provide an image processing circuit capable of matching karaoke data and the moving speed or change of a background image to provide the background image most suitable to the music by inserting a control command to a prescribed position of karaoke data, and giving an effect on the background image according to this control command. SOLUTION: After a music data is decoded to a signal reproducible by a speaker, a control command superposed on the music signal is extracted by a control command extracting circuit 19. The kind of the control command is judged by a control command judging circuit 20, and a processing such as negative-positive reversion to image is performed by an image effect circuit 25. Since an effect is given to the background image according to music change, the music and the background image can be integrally changed.
