ARTIFICIAL RETINA STIMULATOR AND APPARATUS WITH IMAGE JITTERING FUNCTION

摘要

Disclosed is an artificial retinal stimulator and an artificial retinal device which are for providing image jittering. The artificial retinal stimulator for providing the image jittering according to the present invention includes: a photodiode configured to sense light stimulation and generate a current based on an intensity of the stimulation; a pulse generator configured to generate a pulse to be provided to a corresponding stimulation electrode on the basis of the current coming from the photodiode; a switch configured to connect an output terminal of the pulse generator and ground; and a jittering switch configured to determine whether to transfer the generated pulse to the corresponding stimulation electrode or to transfer to a stimulation electrode corresponding to another artificial retinal stimulator. According to the present disclosure, an image jittering function capable of emulating an eye blinking effect is provided, so that it is possible to enable a low vision patient to see images better.
