Claim One:
1. A method of brightness fitting for a visual prosthesis comprising: a. providing an external video processor and an implantable visual neural stimulator including an array of electrodes suitable to contact visual neural tissue; b. testing the implantable visual neural stimulator to verify function and matching to the external video processor; c. activating a prompt; d. activating signals at varying levels on a selected electrode within a subset of electrodes in the array of electrodes; e. receiving a response from a subject indicating a visual perception; f. recording the level that elicited the response indicating the visual perception; g. repeating the steps c through f for each electrode in the subset; h. determining if a predetermined minimum number of electrodes in the subset elicited responses indicating visual perceptions; i. if the predetermined minimum number of electrodes did not elicit responses indicating the visual perceptions, activating the subset of electrodes in the array of electrodes simultaneously as a group at varying levels; j. receiving a subset response from a subject indicating a subset visual perception; and k. recording the level that elicited the subset response indicating the subset visual perception from stimulating the subset of electrodes.
