本文介绍了一种基于CCD图像传感器和FPGA的自动聚焦系统的设计方法。设计中利用FPGA对CCD图像传感器输出的图像信号的亮度分量进行滤波，灰度差分，并配合一定的搜索策略算法通过控制步进电机的转动，使光学镜头移动到聚焦最清楚的位置，从而完成了对一帧图像自动聚焦的实现。
his paper presented a design method of auto-focus system based on CCD image sensor and FPGA. Capture luminance value from sensor as input signal, filter and make gray difference with search strategy to remove step-motor so that make optics lens stop in the position of accurate focus to finish auto-focus for a image.
