Development of an image down sampling and transmission system for the construction of artificial eye

Abstract

The project is under a research of visual prosthesis which is manufactured by the electronic retina implant. The purpose is to restore the second visual sight for the blinds. With the support of wireless charging technique, the minimized internal camera receiver is being implemented in this project. The research draws upon the previous technology- The Argus II, which provides external camera receiver. By combining Bluetooth module, camera and micro controller internally, the visual signal could be transmitted effectively. The project could be divided as two main parts, hardware design and programming. In the programming part, it is need to convert the analogy signal to digital signal with the detectable resolution for the electrode array, and convert the signal to black and white mode. Also, it provides an instant video signal for the blinds in advanced. In the hardware part, the major work is to design the Print Circuit Board (PCB) to provide the stable signal transmission platform for the camera, and also power supply part with the match coils. For the sake of minimizing the implanted camera device effectively, the innovative idea of creating a PCB cube is shown. In this project, the new system of visual prosthesis is being implemented. It could enhance the efficiency of the power and quality of image transmission.
