Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we proposed SPAD image sensor with pixel-wise exposure control that satisfies both high dynamic range and low power consumption. The proposed SPAD sensor achieved array size of 1 Megapixel, 0.37W power consumption, and 143dB dynamic range. In addition, the proposed SPAD sensor can capture images with low noise by using adaptive clocked recharging that limits the number of saturation counts in a low-light scene.
