WiFi属于短距离无线传输技术，移动终端通过WiFi模块102可以帮助用户收发电子邮件、浏览网页和访问流式媒体等，它为用户提供了无线的宽带互联网访问。虽然图1示出了WiFi模块102，但是可以理解的是，其并不属于移动终端的必须构成，完全可以根据需要在不改变发明的本质的范围内而省略。
音频输出单元103可以在移动终端100处于呼叫信号接收模式、通话模式、记录模式、语音识别模式、广播接收模式等等模式下时，将射频单元101或WiFi模块102接收的或者在存储器109中存储的音频数据转换成音频信号并且输出为声音。而且，音频输出单元103还可以提供与移动终端100执行的特定功能相关的音频输出(例如，呼叫信号接收声音、消息接收声音等等)。音频输出单元103可以包括扬声器、蜂鸣器等等。
A/V输入单元104用于接收音频或视频信号。A/V输入单元104可以包括图形处理器（Graphics Processing Unit，GPU）1041和麦克风1042，图形处理器1041对在视频捕获模式或图像捕获模式中由图像捕获装置（如摄像头）获得的静态图片或视频的图像数据进行处理。处理后的图像帧可以显示在显示单元106上。经图形处理器1041处理后的图像帧可以存储在存储器109（或其它存储介质）中或者经由射频单元101或WiFi模块102进行发送。麦克风1042可以在电话通话模式、记录模式、语音识别模式等等运行模式中经由麦克风1042接收声音（音频数据），并且能够将这样的声音处理为音频数据。处理后的音频（语音）数据可以在电话通话模式的情况下转换为可经由射频单元101发送到移动通信基站的格式输出。麦克风1042可以实施各种类型的噪声消除(或抑制)算法以消除(或抑制)在接收和发送音频信号的过程中产生的噪声或者干扰。

基于上述移动终端硬件结构，提出本申请方法各个实施例。
本申请提供一种终端拍摄方法，该终端拍摄方法应用于移动终端，在终端拍摄方法一实施例中，参照图2，该终端拍摄方法包括：
步骤S10，获取并跟踪终端相机预览框拍摄目标的位移信息；
本申请的执行主体可以是一个终端拍摄应用；终端相机预览框指的是用户打开移动终端相机应用之后移动终端相机的显示界面；当用户打开移动终端相机时，用户通过调整持有的移动终端的位置使得拍摄目标按照用户的拍摄构图显示在预览框中，此时拍摄目标会在预览框中发生移动，从而拍摄目标的速度和方向发生改变，即产生了位移，描述位移的信息即为位移信息。
步骤S20，根据位移信息确定预测对焦区域，在预测对焦区域进行对焦；
预测对焦区域指的是位于移动的拍摄目标在已形成的位移的基础上，接下来将有可能形成的轨迹上的区域；在预测对焦区域进行对焦指的是终端拍摄应用在拍摄目标进入预测对焦区域之前，提前在预测对焦区域进行对焦。
步骤S30，判断拍摄目标是否进入预测对焦区域；
由于拍摄目标在拍摄过程中会发生位移，并非绝对静止，因此拍摄目标在移动过程中，跟预测对焦区域的位置关系会发生实时变化。
步骤S40，若拍摄目标进入预测对焦区域，则完成拍摄目标的拍摄。
当判断得出拍摄目标进入预测对焦区域时，则可进行拍摄，无需用户手动对焦。
在本实施例中，在对非静止的活体（人或有生命的动植物体）和非静止的物体进行拍摄时，通过先获取并跟踪终端相机预览框拍摄目标的位移信息；然后根据所述位移信息确定预测对焦区域，在所述预测对焦区域进行对焦；最后判断所述拍摄目标是否进入所述预测对焦区域；若所述拍摄目标进入所述预测对焦区域，则完成所述拍摄目标的拍摄。本申请在预测对焦区域进行对焦，当拍摄目标进入预测对焦区域则进行拍摄，无需用户手动对焦，避免了拍摄目标的位置改变从而导致对焦不准以及照片不清晰，改善了拍摄效果；同时简化了拍摄流程，减少了用户拍摄操作步骤，提升了用户体验。
进一步地，在本申请终端拍摄方法一实施例的基础上，所述位移信息包括当前时刻之前预设单位时长内的历史运动轨迹，参照图3 ，步骤S20包括:
步骤S21，根据历史运动轨迹，获取拍摄目标在下一个预设单位时长的预测运动轨迹；
历史运动轨迹属于位移信息之一，指的是拍摄目标在终端相机预览框中已经发生的位移所形成的轨迹；下一个预设单位时长的预测运动轨迹指的是拍摄目标在当前时刻之后的预设单位时间内将有可能发生的位移所形成的轨迹。
步骤S22，根据预测运动轨迹上的位置点，确定预测对焦区域。
预测运动轨迹上的位置点指的是形成拍摄目标预测运动轨迹的点。
在本实施例中，首先由信息获取模块获取拍摄目标的历史运动轨迹，然后由历史运动轨迹得到预测运动轨迹，再由预测运动轨迹上的位置点确定预测对焦区域，从而本终端拍摄应用可以提前在预测对焦区域进行对焦，只要拍摄目标进入预测对焦区域便可进行拍摄，避免了对焦不准而导致照片不清晰。
进一步地，在本申请终端拍摄方法一实施例的基础上，所述位移信息还包括拍摄目标的对象属性，参照图4 ，步骤S21包括:
步骤S211，确定拍摄目标的对象属性，并根据对象属性，确定拍摄目标的运动规律描述表和预测运动速度，其中运动规律描述表包括运动参考点与运动参考点所映射的预测运动方向；
拍摄目标的对象属性属于另一个位移信息，指的是拍摄目标可以为人类、动物、植物、物体其中一种或者多种；运动参考点与运动参考点所映射的预测运动方向指的是根据对象属性的普遍运动规律，得出的拍摄目标在某一个运动参考点时所对应的预估的运动方向，如摇摆的大钟，简称钟摆，当选取的运动参考点为钟摆运动轨迹的最低点时，则大钟在这个运动参考点的预测运动方向为钟摆运动轨迹的切线方向；运动规律描述表指的是描述不同对象属性的运动参考点与预测运动方向的映射关系表，由运动规律描述表可以查询到运动参考点以及运动参考点所映射的预测运动方向；预测运动速度指的是根据对象属性的普遍运动规律，预测拍摄目标的运动速度；因为不同类型的对象属性，运动规律和运动速度不同，因此需要通过先确定拍摄目标的对象属性，再根据对象属性确定拍摄目标的运动规律和预测运动速度。
步骤S212，根据运动规律描述表、预测运动速度和历史运动轨迹，确定拍摄目标在下一个预设单位时长的预测运动轨迹。
运动规律描述表可以查询与拍摄目标运动参考点存在映射关系的预测运动方向；当确定了预测运动方向和预测运动速度，再结合历史运动轨迹，便可以确定拍摄目标的预测运动轨迹。
在本实施例中，首先确定拍摄目标的对象属性，然后根据对象属性确定拍摄目标的运动参考点、预测运动方向和预测运动速度，最后结合历史运动轨迹，确定拍摄目标在下一个预设单位时长的预测运动轨迹。
进一步地，在本申请终端拍摄方法一实施例的基础上，参照图5 ，步骤S212包括:
步骤A10，根据历史运动轨迹确定拍摄目标的当前运动参考点；
当前运动参考点指的是历史运动轨迹上当前时刻的位置点。
步骤A20，在运动轨迹描述表搜索到当前运动参考点所映射的预测运动方向；
运动轨迹描述表中每个参考运动点都有各自对应的预测运动方向，只有确定了参考运动点的方向，才能预估拍摄目标的运动方向。
步骤A30，根据预测运动速度和预测运动方向，确定预测运动轨迹。
当确定了预测运动速度和预测运动方向，便可预估拍摄目标从当前运动参考点之后的运动轨迹，得到预测运动轨迹。
在本实施例中，参照图10，假设拍摄目标为摇摆的大钟，简称钟摆，此钟摆的历史运动轨迹（弧线实线部分）为从钟摆能达到的左侧最高点运动到钟摆垂直地面的点，即最低点：当选取其运动轨迹的最低点为运动参考点时，则最低点对应的预测运动方向为钟摆运动轨迹的切线方向；预测运动速度为由最低点的最大速度逐渐减小；预测运动轨迹（弧线虚线部分）为由最低点运动到右侧最高点。
进一步地，在本申请终端拍摄方法一实施例的基础上，参照图6，步骤S22包括:
步骤S221，取预设个数预测运动轨迹上的位置点，确定预测运动轨迹上的各位置点所构成图形的参考位置中心；
参照图11，取预测运动轨迹上的3个位置点，则这3个为位置点构成的三角形的中心为参考位置中心。
步骤S222，以参考位置中心为几何中心，确定预测对焦区域。
将参考位置中心作为预测对焦区域的几何中心之后，用户可以对预测对焦区域进行调整，如放大、缩小、旋转等，从而得到预测对焦区域。
在本实施例中，通过取预设个数预测运动轨迹上的位置点所构成图形的参考位置中心作为预测对焦区域的几何中心，从而确定预测对焦区域，使预测对焦区域更大可能处于拍摄目标将要移动至的位置。
进一步地，在本申请终端拍摄方法一实施例的基础上，参照图7，步骤S222包括:
步骤A40，将参考位置中心作为各拍摄目标所形成的整体区域的几何中心；
在确定参考位置中心之后，可将所述参考位置中心作为各所述拍摄目标所形成的整体区域的几何中心；即先确定涵盖所有拍摄目标的框选整体区域的基准中心位置。
步骤A50，根据各所拍摄目标相对终端屏幕的屏占比，确定整体区域的显示尺寸，以生成预测对焦区域。
根据各所述拍摄目标相对终端屏幕的屏占比，确定所述整体区域的显示尺寸，拍摄目标想对终端屏幕的屏占比越大，该整体区域的显示尺寸越大，
在本实施例中，在确定整体区域的几何中心位置为参考位置中心，以及基于所述屏占比确定整体区域的显示尺寸之后，将此时的整体区域作为预测对焦区域，以生成预测对焦区域，从而预测对焦区域的尺寸适中，既能包含所有拍摄目标又不至于尺寸过大，并且预设对焦区域的位置处于预测运动轨迹上，更利于后续准确对焦拍摄目标。
进一步地，在本申请终端拍摄方法一实施例的基础上，步骤S30包括:
判断各拍摄目标所形成的整体区域的几何中心与预测对焦区域的几何中心是否重合，若重合则判定所述各拍摄目标进入预测对焦区域。
当拍摄目标个数为一个时，参照图12，几何中心为此拍摄目标的重心；当拍摄目标个数不止一个时，参照图13，几何中心为各个拍摄目标形成的整体区域的重心，而当拍摄目标个数不止一个时，移动过程中各个拍摄目标的速度大小与方向的改变不一定保持一致，因此每个位置重心会发生实时变化；当拍摄目标的几何中心与预测对焦区域的几何中心重合时，说明拍摄目标的几何中心与预测对焦区域的几何中心在终端相机的预览框中位置相同，从而得出拍摄目标进入预测对焦区域。
在本实施例中，通过判断拍摄目标是否进入对焦区域，若进入则可进行拍摄，从而避免了对焦不准的问题，提升了拍摄效果。
进一步地，在本申请终端拍摄方法一实施例的基础上，步骤S10之前的步骤包括：
步骤A60，检测终端相机预览框的拍摄目标是否为非静止的活体或者非静止的物体；
拍摄目标指的是用户想要进行拍摄的非静止的活体（人或者有生命的动植物）或者物体，如行走的人、活泼好动的宠物、风中飘动的植物、前进的列车、摇摆的大钟等等。
步骤A70，若是，则执行获取并跟踪终端相机预览框拍摄目标的位移信息的步骤。
当拍摄目标为非静止的活体或者非静止的物体，再获取拍摄目标的位移信息。
在本实施例中，先判断拍摄目标是否为非静止的活体或者非静止的物体，若是再执行获取拍摄目标的位移信息的步骤，提升了信息获取的准确率。
进一步地，在本申请终端拍摄方法一实施例的基础上，步骤S40包括：
若拍摄目标进入预测对焦区域，则用户可手动确认拍摄或者启动拍摄模块自动拍摄。
当拍摄目标进入预测对焦区域，说明已经完成了拍摄目标的对焦，此时用户可以手动点击确认框完成拍摄目标的拍摄；或者由本应用启动拍摄模块，自动完成拍摄目标的拍摄，且自动拍摄的效果比手动拍摄效果更佳。
在本实施例中，完成拍摄目标的拍摄有手动拍摄和自动拍摄两种方式：手动方式方便用户自主选择拍照时机，而自动拍摄的效果比手动拍摄效果更佳。
此外，参照图8，本申请实施例还提出一种终端拍摄装置，终端拍摄装置包括：

区域确定模块，用于根据位移信息确定预测对焦区域，在预测对焦区域进行对焦；
