    摘要： An image plane includes a plurality of pixels. Each pixel comprises a photodiode and two transistors, and each pixel is connected by a signal bus to a respective storage node located off the image plane. Each storage node comprises two capacitors and associated switches. One of the transistors applies a reset pulse to the pixel, and the other transistor connects the pixel to a given conductor of the signal bus, which is then connected to the storage node. The pixel transistors can be operated simultaneously, and the sensed values can subsequently be transferred from the storage nodes sequentially.

    摘要翻译： 图像平面包括多个像素。 每个像素包括光电二极管和两个晶体管，并且每个像素通过信号总线连接到位于图像平面外的相应存储节点。 每个存储节点包括两个电容器和相关联的开关。 其中一个晶体管将复位脉冲施加到像素，另一个晶体管将像素连接到信号总线的给定导体，该导体然后连接到存储节点。 像素晶体管可以同时操作，并且随后可以从存储节点依次传送感测值。
