    • An autofocus system is provided that includes a focus-verification image-recapturing processor and a focus-verification image display processor. The focus-verification image-recapturing processor sets ISO sensitivity to a value lower than a predetermined value and increases an exposure value by adjusting at least one of an aperture value and an exposure time to carry out a focus-verification image-recapturing operation under focusing conditions applied in an antecedent autofocus operation when ISO sensitivity that is set in said auto focus operation exceeds the predetermined value. The focus-verification image display processor displays a focus-verification image obtained by the focus-verification image-recapturing operation when the ISO sensitivity that is set in the auto focus operation exceeds the predetermined value.
    • 提供了一种自动对焦系统,其包括聚焦验证图像再捕获处理器和焦点验证图像显示处理器。 焦点验证图像重新获取处理器将ISO感光度设置为低于预定值的值,并且通过调整光圈值和曝光时间中的至少一个来增加曝光值,以在聚焦下执行聚焦验证图像重新捕获操作 当在所述自动聚焦操作中设定的ISO感光度超过预定值时,在先前的自动对焦操作中应用的条件。 当在自动聚焦操作中设置的ISO感光度超过预定值时,焦点验证图像显示处理器显示通过聚焦验证图像重新获取操作获得的聚焦验证图像。
