具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
图1为一个实施例中防抖行程调节方法的流程图。如图1所示，一种防抖行程调节方法，包括步骤102至步骤106。其中：
步骤102，检测移动设备的抖动方向。
移动设备可为具有拍摄功能的设备。该移动设备可为手机、平板电脑、穿戴式设备、个人数字助理等。移动设备被放置在支架或使用者手上拍摄时会产生一定的抖动。可通过移动设备中的陀螺仪检测移动设备的抖动方向。具体地，可通过陀螺仪检测移动设备在XYZ轴上的加速度，根据所述加速度增加的方向确定所述抖动方向。可将加速度增加的方向作为抖动方向。
例如，陀螺仪检测到移动设备在XYZ轴上的初始加速度均为0，当发生抖动时，检测到移动设备在XY轴上的加速度为0，在Z轴上的加速度为3，则将Z轴方向作为抖动方向。
在一个实施例中，可通过移动设备对待拍摄的画面拍摄多张图像，计算连续多张图像之间的偏移量，根据偏移量计算抖动方向。
步骤104，根据所述抖动方向生成调节指令。
具体地，生成的调节指令可为默认控制镜头沿着与抖动方向相同的方向移动的指令，也可为控制镜头移动的指令。
步骤106，根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照防抖时的可移动行程。
镜头是移动设备的图像采集装置中由透镜组成的光学装置，用于在成像传感器上成像。镜头防抖的可移动行程是指拍照时镜头在同一个平面内可以 移动的距离。镜头防抖的可移动行程即为防抖行程，是指镜头在上下、左右平面上可以移动的距离。
控制镜头沿着与抖动方向相同可以是与抖动方向趋同的方向，即与抖动方向不限于完全一致。与抖动方向相反可以是与抖动方向相反方向的趋同方向，即与抖动方向相反方向不限于完全一致。
拍照过程中通过控制防抖装置的电机使得镜头进行移动可以对抖动进行补偿，使得光路保持稳定，镜头的可移动行程越大，拍照时进行抖动补偿的空间越大，防抖效果越好。
上述防抖行程调节方法，检测到移动设备的抖动方向，生成调节指令，根据调节指令控制镜头沿着与抖动方向相同或相反的方向移动，以增大镜头在拍照时的可移动行程，提高了防抖效果。
在一个实施例中，所述根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照时的可移动行程包括：
根据所述调节指令控制镜头沿着与所述抖动方向相同的方向移动；
判断所述镜头的可移动行程是否增加，若是，则继续控制所述镜头沿着与所述抖动方向相同的方向移动，若否，则控制所述镜头沿着与所述抖动方向相反的方向移动。
在根据调节指令控制镜头沿着与抖动方向相同的方向移动后，获取镜头的可移动行程，将移动后镜头的可移动行程与移动前镜头的可移动行程比较，若移动后镜头的可移动行程大于移动前镜头的可移动行程，则表明镜头的可移动行程增加了，若移动后镜头的可移动行程小于移动前镜头的可移动行程，则表明镜头的可移动行程减小了，则移动方向错误，停止移动，并控制镜头沿着与抖动方向相反的方向移动。
镜头的可移动行程可通过距离传感器进行检测得到。
通过控制镜头先向抖动方向相同的方向移动，若检测到可移动行程减小，则及时控制镜头向抖动方向相反的方向移动，保证增大镜头的可移动行程，以保证提高防抖效果。
在一个实施例中，所述根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照时的可移动行程包括：根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动预设距离，以增大所述镜头在拍照时的可移动行程。
具体地，预设距离可为预先设定的距离。该预设距离小于或等于镜头可移动的最大距离。镜头可移动的最大距离受限于移动设备中图像采集装置的具体结构所形成的可供镜头活动的空间范围等。移动设备的镜头通常会在光轴上进行移动，也就是在一个空间维度上移动。可控制每次移动的距离，控制更加精准。
在一个实施例中，所述根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照时的可移动行程包括：移动设备的处理器根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向按照预设增幅移动，以增大所述镜头在拍照时的可移动行程。
具体地，预设增幅可为预设的增加的幅度，例如5％、10％等。预设增幅也可为抖动幅度的比例值。抖动幅度是指发生抖动的幅度，可通过加速度增幅得到。加速度增幅可通过加速度增加值与增加前的加速度的比值得到。
按照预设增幅移动可为按照当前可移动行程的预设增幅移动，或者按照镜头可移动的最大距离的预设增幅移动。当前可移动行程是指镜头每次在移动前的可移动行程。
通过设定预设增幅，可更加精细的控制镜头的移动。
图2为另一个实施例中防抖行程调节方法的流程图。如图2所示，在一个实施例中，一种防抖行程调节方法，还包括步骤202至步骤206。其中：
步骤202，在拍照预览时，实时检测移动设备的抖动方向。
拍照预览是指拍照之前捕捉画面的情况。移动设备可通过陀螺仪实时检测移动设备在XYZ轴上的加速度，根据所述加速度增加的方向确定所述抖动方向。可将加速度增加的方向作为抖动方向。
步骤204，根据所述抖动方向生成调节指令。
步骤206，实时根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照时的可移动行程。
为了保证实时调整每次能够移动到位，实时检测的频率可以调高，每次移动的距离调小。实时检测的频率大于预设频率。移动距离小于指定距离。
上述调节防抖行程调节方法，检测到移动设备的抖动方向，生成调节指令，根据调节指令控制镜头沿着与抖动方向相同或相反的方向移动，以增大镜头在拍照时的可移动行程，提高了防抖效果。
在一个实施例中，步骤206可包括：根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动预设距离，以增大所述镜头在拍照时的可移动行程。该预设距离可设定的较小，以保证每次能够迅速移动到位。

步骤304，根据所述抖动方向生成调节指令。
步骤306，根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动，以增大所述镜头在拍照时的可移动行程。
具体地，微电机根据所述调节指令控制镜头沿着与所述抖动方向相同的方向移动；判断所述镜头的可移动行程是否增加，若是，则继续控制所述镜头沿着与所述抖动方向相同的方向移动，若否，则控制所述镜头沿着与所述抖动方向相反的方向移动。
在一个实施例中，根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向移动预设距离，以增大所述镜头在拍照时的可移动行程。
在一个实施例中，根据所述调节指令控制镜头沿着与所述抖动方向相同或与相反的方向按照预设增幅移动，以增大所述镜头在拍照时的可移动行程。
步骤308，检测到镜头移动完成，执行所述拍照指令。
镜头移动完成后，执行拍照指令，调用防抖装置的电机控制镜头的可移动行程增大，提高了防抖效果。
上述防抖行程调节方法，检测接收到拍照指令是移动设备的抖动方向，生成调节指令，根据调节指令控制镜头沿着与抖动方向相同或相反的方向移动，以增大镜头在拍照时的可移动行程，在镜头移动完成后，进行拍照，调用防抖装置，镜头的可移动行程增大，提高了防抖效果。
