Abstract
An artificial eye system may include an extracorporeal unit mounted outside a user's body and an intracorporeal unit 3 mounted inside a user's eye. The extracorporeal unit 2 may include a visor and a power supply unit. The visor may include a primary coil, an image receiving element that receives a picture image, a light emitting element that transmits an electric stimulus signal produced based on an image signal from the image receiving element, and an eye-gaze point recognizing unit. The intracorporeal unit may include a secondary coil that is electro-magnetically induced by the primary coil, a light receiving element that receives the electric stimulus signal from the light emitting element, a signal processing circuit that processes the electric stimulus signal received by the light receiving element, and a plurality of electrodes that transmits the electric stimulus signal processed by the signal processing circuit to the retina.
