ARTIFICIAL RETINA SYSTEM FOR IMPROVING CONTRAST SENSITIVITY

摘要

Provided is an artificial retina system for improving contrast sensitivity. The artificial retina system, according to one embodiment of the present invention, comprises: an artificial retina (100) which is installed under the retina and includes a plurality of photodiode cells (110); and a microcomputer (200) for comparing, with at least one reference value, the magnitude of an electric signal outputted from a photodiode 111 in each of the photodiode cells (110), and controlling to amplify or reduce the electric signal outputted by each of the photodiode cells (110) according to the result of comparison, wherein visual cells corresponding to each of the photodiode cells (110) can be stimulated with an electric signal controlled by the microcomputer (200).
