CD的输出信号幅值变化情况，并利用Matlab对连续输出100帧图像的平均灰度值进行分析计算。结果表明：该方法有效地实现了CCD曝光时间的控制，且仅通过软件调节，易于实现，可以广泛应用于不带电子快门的帧转移型面阵CCD成像器件。

A new method for exposure time control by driver timing was proposed for non-electronic shutter frame transfer area CCD imaging detector. Based on the Sarnoff′s back illuminated frame transfer array CCD sensor, the charge will be drained quickly in the excess period, with the driver timing controlled by the software. Selecting exposure time as 2 ms, 4 ms, 6 ms and 9.96 ms, the CCD output signal amplitude was measured under system frame frequency of 100 fps. The gray value of continuous 100 frame image calculated by the Matlab. Results show that the method can control the CCD exposure time effectively, and can be implemented by software. It can be widely used in the frame transfer area CCD imaging device without electronic shutter.
