Abstract

An apparatus for improving performance of a retinal implant may include processing circuitry. The processing circuitry may be configured to receive image data corresponding to a camera field of view, determine whether a particular object is detected within the camera field of view, perform image data processing to enable a representation of a portion of the image data corresponding to an implant field of view to be provided on a retinal implant where the implant field of view is smaller than the camera field of view, and, responsive to the particular object being located outside the implant field of view, provide a directional indicator in the implant field of view to indicate a location of the particular object relative to the implant field of view.
