| Abstract: | 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. |

| Keywords: | CMOS image sensor timing control high frame rate wide dynamic range |
