Artificail vision system

摘要

An object is to provide an artificial vision system ensuring a wide field of view without damaging a retina. In the artificial vision system, a plurality of electrodes ( 23 ) are to be implanted so as to stick in an optic papilla of an eye of a patient. A signal for stimulation pulse is generated based on an image captured by an image pick up device ( 11 ) to be disposed outside a body of the patient. The electrical stimulation signals outputted from the electrodes ( 23 ) based on the signals for stimulation pulse stimulate an optic nerve of the eye, thereby enabling the patient to visually recognize the image from the image pickup device ( 11 ).
