  • Patent number: 7263404
    Abstract: A visual restoration aiding device for restoring vision of a patient comprises an electrode array having a plurality of electrodes placed on or under a retina of an eye of the patient for applying an electrical stimulation pulse signal to cells constituting the retina; a photographing unit which photographs an object to be recognized by the patient; a converting unit which converts photographic data transmitted from the photographing unit to data for electrical stimulation pulse signals; and a control unit which outputs an electrical stimulation pulse signal through each electrode based on the data for electrical stimulation pulse signals so that the control unit produces pulse output through one of a first electrode and a second electrode during a halt time of pulse output through the other electrode, the first and second electrodes being arranged within a distance such that electrical stimulation pulse signals outputted therethrough at substantially the same time are likely to interfere with each other.
