Method and system for providing stimulation inputs to a visual prosthesis implant
Stimulation inputs are provided to a visual prosthesis implant. The images captured by a video decoder are received and digitized to provide a plurality of video frames; integrity of the video frames is checked, the checked video frames are filtered, and the filtered video frames are converted to stimulation inputs. A similar system is also disclosed.
1. A system for providing stimulation inputs to a visual prosthesis implant, comprising:
a camera providing images to a video decoder;
a receiver to receive the images captured by the video decoder yielding received images;
a digitizer to digitize the received images to provide a plurality of video frames;
a video input handler to check integrity of the video frames to provide checked video frames;
a video filter processor to filter the checked video frames to provide filtered video frames; and
a telemetry engine video manager to convert the filtered video frames to stimulation inputs for the visual prosthesis implant.
2. The system of claim 1 , wherein the video input handler also detects a video overrun.
3. The system of claim 1 , wherein the video filter processor employs spatial mapping.
4. The system of claim 3 , wherein the visual prosthesis implant includes a plurality of electrodes and the spatial mapping is employed for each electrode.
5. The system of claim 1 , wherein the telemetry engine video manager uses a brightness map.
6. The system of claim 1 , wherein the video input handler, the video filter processor and the telemetry engine video manager are in a digital signal processor (DSP), the DSP configured to be connected with the visual prosthesis implant.
7. The system of claim 6 , wherein the DSP is located in a video processing unit (VPU).
8. The system of claim 7 , wherein the video decoder is configured to be connectable to a camera and wherein the video input handler, the video filter processor and the telemetry engine video manager operate with a connected camera.
9. The system of claim 1 , wherein the video decoder is configured to be connectable to a camera and the video input handler, the video filter processor and the telemetry engine video manager operate with a disconnected camera.
