本文主要论述了CMOS图像传感器时序控制电路的系统设计和实现方法.针对双采样结构的图像传感器
分析了常用的并行式曝光方式和滚筒式曝光方式两种时序控制方法及其具体实现过程
并根据时序控制电路的功能仿真和在FPGA上的验证结果
对二者进行了比较
证明了这两种方法的可行性.
The system design and implementation methods of timing control circuit for a new CMOS image sensor are proposed.Using dual-sampling pixel architecture
the CMOS image sensor can achieve both high frame rate and wide dynamic range.Two efficient timing control methods(one named "roll exposure mode"
and the other "parallel exposure mode") are both proved right and feasible
by analyzing their theoretical operation principle and the results from function and timing simulation and FPGA verification.
