Abstract:
1. A method for assigning image pixels of a digital image to electrodes of a visual prosthesis, the electrodes adapted to provide electrical signals to a patient according to a temporal stimulation pattern, the temporal stimulation pattern defining one or more timing groups of electrodes, the method comprising: a) providing an image source and a video processing unit; b) sending a digital image from said image source to said video processing unit; c) selecting a group of brightest pixels of the digital image in the video processing unit; d) selecting a group of remaining pixels, not in said group of brightest pixels; e) dividing the digital image into timing groups; f) spreading said group of brightest pixels across more than one of said timing groups; g) repeating a) and b) for said group of remaining pixels of the image, until all pixels have been assigned to said one or more timing groups; and h) stimulating visual neurons to induce said digital image by stimulating pixels in different timing groups at different times.
