自动聚焦是成像自动化的重要组成部分之一。为了提高聚焦精度、减少聚焦时间，提出了一种图像模糊度和清晰度相结合的自动聚焦算法。在严重离焦的状态下，首先计算图像的模糊度来确定聚焦电机的正确搜索方向，再由图像的清晰度结合优化爬山算法，确定准确的对焦位置。结果表明，这种方法能很好地减少聚焦时间，聚焦准确度高。

Auto-focusing was an important part of imaging automation .In order to improve the focus accuracy and reduce the time of auto-focusing, an auto-focusing algorithm combining image ambiguity and image clarity was presented .At first, in the severe defocused state, the correct search direction of focus-motor was determined by the value of image ambiguity .And then, the correct focus position was determined by the value of image clarity and the optimized mountain climbing servo .The results show that this method could reduce focus time and obtain the high focus accuracy .
