Abstract (in Japanese) (See Japanese page) 
(in English) Event-based vision sensor (EVS) generally faces issues with false detection, commonly known as the background rate (BGR), because of pixel noise, especially in the case of low illuminance. Previous studies have shown that EVS pixel noise depends on the specific parasitic capacitance and bias current in logarithmic EVS pixels. However, studies providing pixel design guidelines for controlling BGR in the more advantageous gain-boosted EVS pixels are limited. Therefore, we aim to develop a guideline for pixel design by proposing a method for controlling the BGR. This approach involves adjusting the specific parasitic capacitance in gain-boosted EVS pixels. In addition, we show the measurement results demonstrating the validity of this method.
