To cope with the increasing number of visually impaired people due to the aging of the population, research on artificial vision, which reconstructs vision using engineering methods, is being actively conducted. To realize the artificial vision with high QOL, it is important to implement the Light and Dark Adaptation (LDA) function, one of the human retinal functions. Although several methods to implement the LDA function have been proposed using electronic circuits, some issues remain regarding function accuracy and circuit area. This study developed an integrated circuit for artificial vision that realizes a small-area appropriate LDA function with high accuracy by introducing a feedback function that changes the sensitivity control signal in steps.
