Patent ID: 7248928

Claim:
An artificial eye system in which stimulus signal producing means converts an image signal, which represents an image of an outside world received by an image receiving element, into an electric stimulus signal, and the electric stimulus signal is transmitted from an electrode attached to a retina, the system including: an extracorporeal unit which is mounted outside a user's body; and an intracorporeal unit which is mounted inside the user's body, wherein the extracorporeal unit includes a visor and a power supply unit which supplies electricity to the visor, the visor includes a primary coil, the image receiving element, and a light emitting element which transmits the image signal from the image receiving element as an imaging signal, and the intracorporeal unit includes: a secondary coil which is electro-magnetically induced by the primary coil to supply electric power to the intracorporeal unit; a single light receiving element which receives the imaging signal from the light emitting element; a signal processing circuit which processes the imaging signal received by the light receiving element; and an electrode unit which is placed away from the signal processing circuit and electrically connected to the signal processing circuit though a cable, and has a plurality of electrodes that transmits the electric stimulus signal to the retina and a demultiplexer that transmits the electric stimulus signal processed by the signal processing circuit to each electrode.
