| 中文摘要: |
| 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. |
| 英文摘要: |
| 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. |
