    • Systems, methods, and computer readable media for dynamically adjusting an image capture device's autofocus (AF) operation based, at least in part, on the device's orientation are described. In general, information about an image capture device's orientation may be used to either increase the speed or improve the resolution of autofocus operations. More particularly, orientation information such as that available from an accelerometer may be used to reduce the number of lens positions (points-of-interest) used during an autofocus operation, thereby improving the operation's speed. Alternatively, orientation information may be used to reduce the lens' range of motion while maintaining the number of points-of-interest, thereby improving the operation's resolution.
    • 描述了至少部分地基于设备的取向来动态地调整图像捕获设备的自动对焦(AF)操作的系统,方法和计算机可读介质。 通常,可以使用关于图像捕获装置的取向的信息来提高速度或提高自动对焦操作的分辨率。 更具体地,可以使用诸如从加速度计获得的定向信息来减少在自动对焦操作期间使用的透镜位置(兴趣点)的数量,从而提高操作的速度。 或者,可以使用取向信息来减少透镜的运动范围,同时保持感兴趣点的数量,从而改善操作的分辨率。
