Artificial vision that reconstructs vision by engineering has been studied, and it is important to implement Light-Dark Adaptation (LDA) function, which is one of the retinal functions of humans. In this study, we developed an integrated circuit for artificial vision that realizes an appropriate LDA function in a small area by introducing a feedback function that changes the sensitivity control signal step by step.
