ABSTRACT:
A visual restoration aiding device for restoring vision of a patient, comprises: a substrate which will be placed on or under a retina, a choroid or a sclera of a patient's eye; a plurality of electrodes arranged on the substrate for applying electrical stimulation pulse signals to cells constituting the retina; a photographing unit which photographs an object to be recognized by the patient; and a control unit which controls output of the electrical stimulation pulse signals from each electrode based image data captured by the photographing unit. The number of the electrodes placed on the substrate is less than the number of electrodes that can simultaneously output the electrical stimulation pulse signals based on the image data corresponding to one frame. The control unit is configured to sequentially output the electrical stimulation pulse signals at predetermined time interval based on the divided image data corresponding to one frame so as to allow the patient to recognize the image corresponding to one frame by joining two or more divided sections of the image corresponding to one frame.
