    • An auto-focus method controls a motor to drive an optical lens of a lens module to a focus point and includes steps of: describing a first parabola according to three coordinate points in a coordinate system; describing a second parabola according to a first highest point of the first parabola and two coordinate points selected from the three coordinate points in the coordinate system, wherein the resolution values of two selected coordinate points are greater than that of unselected coordinate point; comparing a difference between the electric current value of a second highest point of the second parabola and the electric current value of the first highest point with a preset value; wherein when the difference is less than the preset value, the second highest point is regarded as the focus point.
    • 自动对焦方法控制电动机将透镜模块的光学透镜驱动到对焦点,并且包括以下步骤:根据坐标系中的三个坐标点描述第一抛物线; 描述根据第一抛物线的第一高点和从坐标系中的三个坐标点中选择的两个坐标点的第二抛物线,其中两个所选坐标点的分辨率值大于未选择的坐标点的分辨率值; 将第二抛物线的第二最高点的电流值与第一最高点的电流值之间的差与预设值进行比较; 其中当所述差小于所述预设值时,所述第二最高点被认为是所述焦点。

    • A power management method for an input device is provided, which includes the following steps: starting to count time and recording a trigger time of the input device after the input device enters a light-sleep mode; and dynamically updating a deep-sleep start time according to the trigger time. When the input device is idle over a standby time, the input device would enter the light-sleep mode and record the trigger time that the input device is restored from the light-sleep mode to an operation mode by a user operating the input device. The method dynamically updates the deep-sleep start time according to the recorded trigger time, and thus better power saving efficiency is achieved.
    • 提供了一种用于输入设备的电源管理方法,包括以下步骤:在输入设备进入轻睡眠模式之后开始计数时间并记录输入设备的触发时间; 并根据触发时间动态更新深度睡眠开始时间。 当输入设备在待机时间空闲时,输入设备将进入睡眠模式,并且通过操作输入设备的用户将输入设备从轻睡眠模式恢复的触发时间记录到操作模式。 该方法根据记录的触发时间动态更新深度睡眠开始时间,从而实现更好的省电效率。
