    • A method for operating an autofocus system for focusing an image on an electronic imager includes providing an adjustable lens system defining an optical path for scene light and having at least one movable lens to focus an image of the scene onto the electronic imager; and causing a first portion of the scene light to be obscured so that the electronic imager captures a first autofocus image and causing a second different portion of the scene light to be obscured so that the electronic imager captures a second autofocus image wherein portions of the first and second autofocus images are offset. The method further includes moving the movable lens to a position so that an image to be captured will be in focus.
    • 一种用于操作用于将图像聚焦在电子成像器上的自动对焦系统的方法包括提供限定用于场景光的光路的可调透镜系统,并具有至少一个可移动透镜以将场景的图像聚焦到电子成像器上; 并且使得场景光的第一部分被遮蔽,使得电子成像器捕获第一自动对焦图像并导致场景光的第二不同部分被遮蔽,使得电子成像器捕获第二自动对焦图像,其中第一 并且第二自动对焦图像被偏移。 该方法还包括将可移动透镜移动到使被捕获的图像成为焦点的位置。
