Patent ID: 8311635

Claim:
A visual prosthesis comprising: a camera receiving an image and generating a pixelized image; a two dimensional array of electrodes suitable for contact with neural tissue; and an image processing circuit configured to receive said pixelized image from said camera and configured to map said image to said two dimensional array of electrodes, said image processing circuit configured to drive an electrode to create a percept in a direct location, drive at least two adjacent electrodes, within said two dimensional array of electrodes, at a first set of levels, based upon said pixelized image, to create a percept at a first location, different from said direct location, between said at least two adjacent electrodes, and configured to drive said at least two adjacent electrodes at a second set of levels, based upon said pixelized image, to create a percept at a second location between said at least two adjacent electrodes, different from said direct location and said first location; wherein each of said direct location, said first location and said second location are mapped from different pixels in said image.
