摘要： Since the accumulation regions fd1, fd2 are connected only to a single capacitor C1, a pixel can be decreased in size to improve spatial resolution. And, charges transferred into the accumulation regions fd1, fd2 are temporarily accumulated, thereby improving a signal-noise ratio. The driving circuit DRV conducts dummy switching so that the number of switching of the first switch Φ1 is equal to the number of switching of the second switch Φ2 after termination of the reset period within one cycle, thus making it possible to cancel offset and obtain a more accurate range image.
摘要翻译：由于累积区域fd1，fd2仅与单个电容器C1相连，因此能够减小像素以提高空间分辨率。并且，暂时累积转移到累积区域fd1，fd2的电荷，从而提高信噪比。驱动电路DRV进行虚拟切换，使得第一开关Φ1的切换次数等于在一个周期内的复位周期结束后的第二开关Φ2的切换次数，从而可以消除偏移并获得更准确的范围图像。
