摘要
自动对焦系统在手机中得到越来越广泛的应用。根据手机镜头焦距短,可调范围窄等特点,全面分析了噪声,视场,清晰度评价函数,窗口选取等各种因数的影响。构建了适于生产线检测的自动对焦系统,并成功地实现快速调焦。
Auto-focusing system has been found wide application in mobile camera . In view of the character of short focus length and small adjustable range, we have analyzed the effects of the noise, field , evaluation function of sharpness definition and window. The auto-focusing system for camera module production line has been set up and it can focus fast as well as accurately.
