摘要
提出了一种新型双采样结构大动态范围CMOS图像传感器的像素阵列结构。该结构在传统的光电二极管型三管有源像素的基础上 ,加入了第二列信号处理电路 ,两列信号处理电路分别处理两次采样。双采样像素结构大幅提高了图像传感器动态范围 。
A new CMOS active pixel array structure that achieves wide dynamic range using dual sampling is reported. This structure adds a second column signal processing circuit to the traditional three transistors active pixel. Two column signal processing circuits processes two sampling signal respectively. High dynamic range can be achieved from dual sampling pixel structure and high speed can be achieved from second column signal processing circuit.
