摘要
<p>The keyboard has a device that dynamically divides keyboard regions in a program controlled manner while playing music. The keyboard regions are changed in real-time while playing the music. Pre-defined instrument sound is produced in a part of the keyboard that is contained in right hand or left hand of a musician while playing the music. Hand positions of the musician are recognized by utilizing optical information. A camera lens (L) monitors keyboard fields (Kr-01, Kr-88) of the keyboard and reports changes of a captured image to an internal system.</p>
