摘要

提出了一种适用于数码相机的无源自动对焦算法。作为一种混合处理技术，该算法利用两种不同的聚焦度量，通过两个阶段提取出聚焦效果最好的图像。利用近轴几何光学成像模型，研究了几种常用的调焦方法，并在此基础上设计了一种鲁棒调焦算法。该算法已在一台数码相机样机上进行了成功的测试。>

IMPLEMENTATION OF A PASSIVE AUTOMATIC FOCUSING ALGORITHM FOR DIGITAL STILL CAMERA

A passive AF algorithm for the digital still camera is proposed. As a class of hybrid processing techniques, the proposed algorithm utilizes the two different focus measures by which the best focused image is extracted via two stages. With the paraxial geometric optics model of image formation, some well-known focus measures are investigated and a robust focusing algorithm is designed based on them. The proposed algorithm has been successfully tested on a prototype digital still camera. >
