Zusammenfassung:An electronic keyboard using a camera, and more particularly, to an electronic keyboard using a camera, which includes a retroreflective film, a light source for irradiating light on to the retroreflective film, a camera for capturing light of a light source retroreflected from the retroreflective film, and an image processing means that analyzes the captured image to track the position of the reflected light source, to find a depressed state of the keyboard, and to generate a sound of an instrument corresponding to the depressed state.
