Abstract:
1. A visual prosthesis comprising: a camera for receiving a pixelized image; a plurality 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 plurality of electrodes, wherein a set of at least three not linearly placed electrodes are stimulated at a first set of levels to create a percept at a first location between said at least not linearly placed electrodes, and said set of at least three not linearly placed electrodes are stimulated at a second set of levels to create a percept at a second location between said at least not linearly placed electrodes, different from said first location; wherein said first set of levels and said second set of levels are determined based on mapping said first location and second location from different pixels in said pixelized image.
