摘　　要：简述了传统和现代自动对焦技术方法并进行对比,在此基础上详细介绍了基于图像处理的自动对焦技术的原理和核心问题,提出了该技术中的关键技术是图像清晰度评价方法和搜索算法并对具体技术进行了描述。Based on brief review and comparison between the traditional and the modern auto-focus methods, the theory and the key points of the auto-focus method based on image processing are put forward. It is figured out that the image- clarity evaluation and searching algorithm are key technologies in the study of auto-focus method based on image pro- cessing. And the approaches of these aspects are described in detail.

关 键 词：图像处理 自动对焦 图像清晰度评价 搜索算法
