Abstract
A camera assembly for filming the hands of a musician playing a finger board instrument includes a guiding device mounted to the finger board instrument. A stage movably engages the guiding device. A camera is mounted on the stage for filming the hands of the fingerboard user as the hands travel along the finger board. A driving device, such as a linear motor, is connected to the stage for moving the stage along the guiding device. A means for controlling the camera is also provided, either manually from a remote location or by visual tracking. A sensor senses the velocity and position of the stage and outputs a detection signal to the control means. The control means transmits command signals to the driving device for actuating movement of the camera along the guiding device.
