Patent ID: 7403822

Claim:
A visual restoration aiding device for restoring vision of a patient, comprising: a substrate which will be placed on a retina, a choroid or a sclera of a patient's eye; an electrode array including 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 of the electrode array based on image data captured by the photographing unit; wherein the control unit is configured to divide the image data corresponding to one frame captured by the photographing unit into a plurality of partial data in one of a vertical direction and a horizontal direction of the image data, to form the electrical stimulation pulse signals corresponding to each of the plurality of divided partial data, and to switch and output the formed electrical stimulation pulse signals from the electrode array at predetermined time intervals in the order along the direction of division of the image data corresponding to one frame so as to allow the patient to recognize the image corresponding to one frame.
