至此，已经按照其功能描述了终端。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型终端等等的各种类型的终端中的滑动型终端作为示例。因此，本发明能够应用于任何类型的终端，并且不限于滑动型终端。
如图1中所示的终端100可以被构造为利用经由帧或分组发送数据的诸如有线和无线通信系统以及基于卫星的通信系统来操作。
现在将参考图2描述其中根据本发明的移动终端能够操作的通信系统。
这样的通信系统可以使用不同的空中接口和/或物理层。例如，由通信系统使用的空中接口包括例如频分多址(FDMA)、时分多址(TDMA)、码分多址(CDMA)和通用移动通信系统(UMTS)(特别地，长期演进(LTE))、全球移动通信系统(GSM)等等。作为非限制性示例，下面的描述涉及CDMA通信系统，但是这样的教导同样适用于其它类型的系统。
参考图2，CDMA无线通信系统可以包括多个移动终端100、多个基站(BS)270、基站控制器(BSC)275和移动交换中心(MSC)280。MSC 280被构造为与公共电话交换网络(PSTN)290形成接口。MSC 280还被构造为与可以经由回程线路耦接到基站270的BSC 275形成接口。回程线路可以根 据若干已知的接口中的任一种来构造，所述接口包括例如E1/T1、ATM，IP、PPP、帧中继、HDSL、ADSL或xDSL。将理解的是，如图2中所示的系统可以包括多个BSC 275。
每个BS270可以服务一个或多个分区(或区域)，由多向天线或指向特定方向的天线覆盖的每个分区放射状地远离BS 270。或者，每个分区可以由配置为分集接收的两个或更多天线覆盖。每个BS 270可以被构造为支持多个频率分配，并且每个频率分配具有特定频谱(例如，1.25MHz，5MHz等等)。
分区与频率分配的交叉可以被称为CDMA信道。BS 270也可以被称为基站收发器子系统(BTS)或者其它等效术语。在这样的情况下，术语“基站”可以用于笼统地表示单个BSC 275和至少一个BS 270。基站也可以被称为“蜂窝站”。或者，特定BS 270的各分区可以被称为多个蜂窝站。
如图2中所示，广播发射器(BT)295将广播信号发送给在系统内操作的移动终端100。如图1中所示的广播接收模块111被设置在移动终端100处以接收由BT 295发送的广播信号。在图2中，示出了几个GPS卫星300。卫星300帮助定位多个移动终端100中的至少一个。
在图2中，描绘了多个卫星300，但是理解的是，可以利用任何数目的卫星获得有用的定位信息。如图1中所示的位置信息模块115即GPS模块通常被构造为与卫星300配合以获得想要的定位信息。替代GPS跟踪技术或者在GPS跟踪技术之外，可以使用可以跟踪移动终端的位置的其它技术。另外，至少一个GPS卫星300可以选择性地或者额外地处理卫星DMB传输。
作为无线通信系统的一个典型操作，BS 270接收来自各种移动终端100的反向链路信号。移动终端100通常参与通话、消息收发和其它类型的通信。特定BS 270接收的每个反向链路信号被在特定BS 270内进行处理。获得的数据被转发给相关的BSC 275。BSC提供通话资源分配和包括BS 270之间的 软切换过程的协调的移动管理功能。BSC 275还将接收到的数据路由到MSC280，其提供用于与PSTN 290形成接口的额外的路由服务。类似地，PSTN 290与MSC 280形成接口，MSC与BSC 275形成接口，并且BSC 275相应地控制BS 270以将正向链路信号发送到移动终端100。
下面将基于上述终端硬件结构以及通信系统，提出本发明方法各个实施例。
下面结合附图和具体实施例对本发明的技术方案进一步详细阐述。
基于前述的实施例，本发明实施例提供一种视频数据的生成方法，该方法应用于终端，该视频数据的生成方法所实现的功能可以通过终端中的处理器调用程序代码来实现，当然程序代码可以保存在计算机存储介质中，可见，该终端至少包括处理器和存储介质。
本发明实施例提供一种视频数据的生成方法。图3为本发明实施例视频数据的生成方法的流程示意图，如图3所示，该视频数据的生成方法包括：
S301：终端的相机运行时，获取拍摄界面的目标区域，从目标区域的对象中确定出目标对象；在接收到拍照指令之后，以距离拍照时刻前预设时间处为起始时刻，以距离拍照时刻后所述预设时间处为结束时刻，按照预设步长获取各图片；
其中，用户点击终端中的相机图标，终端的相机运行，终端的显示界面为相机的拍摄界面，此时拍摄界面上显示待拍画面；然后用户在拍摄界面上圈出目标区域，图4为本发明实施例目标区域的排布示意图，如图4所示，图4中的矩形为用户圈出的目标区域。
需要说明的是，目标区域的形状可以为矩形，圆形，三角形行等等，这里，本发明实施例不做具体限定；
对目标区域进行检测，可以得知目标区域的对象。图4中的目标区域 的对象包括对象1、对象2和对象3；用户选中对象1为目标对象。
图5为本发明实施例视频数据的生成方法中的时刻图，如图5所示，首先用户点击拍摄界面中下方的快门，则终端接收到拍照指令，此时为开始时刻t1，以距离拍照时刻t3前预设时间处为起始时刻t2，以距离拍照时刻t3后所述预设时间处为结束时刻t4，按照预设步长获取各图片。这里，以预设时间为2s，预设步长为1ms举例来说，拍照时刻t3的前2s获取第一张图片，每隔2ms获取一次图片，直到拍照时刻t3后2s结束获取图片；
至此，可以获取到各图片。
S302：从每个图片中，截取出包括目标对象且与目标区域大小相同的区域为每个子图片；
具体来说，在获取到每个图片之后，需要对每个图片进行截图得到每个子图片。其中每个子图片中包括用户选中的目标对象，并且每个子图片的大小与用户选中的目标区域的大小是相同的。
举例来说，如图4所示，假设对象1为人，对象2为红色气球，对象3为蓝色气球，当用户使用终端希望以对象2和对象3为背景的对象1跳起时最精彩的瞬间；那么，在S301中用户圈出目标区域和目标对象之后，终端每次获取到图片之后，截取出包括对象1的且与图4中的矩形大小相同的区域为子图片；这样，便获得了包括目标对象的局部图片，删除掉了不包括目标对象的图片，使得用户所观赏的视频为用户期望看到的画面，提高了用户的体验度。
这里，需要说明的是，本发明实施例中的目标对象可以为一个或者多个，这里本发明实施例中不做具体限定。
S303：将目标区域分别与每个子图片进行匹配，匹配成功时，保留子图片，匹配失败时，丢弃子图片；
在S301中获取到各子图片之后，将目标区域分别与每个子图片进行匹 配，得到匹配结果，当匹配结果为成功的子图片保留起来，将匹配结果为失败的子图片丢弃掉；
这里，需要说明的是，将目标区域分别与每个子图片进行匹配中，指的是将目标区域的对象分别与每个子图片的对象一一进行匹配，例如，一种匹配方式为，目标区域的目标对象与子图片的目标对象匹配成功时，删除子图片中的除了目标对象以外的其他对象，然后保留该子图片；另一种匹配方式为，目标区域的对象与子图片的对象一一进行匹配，匹配成功后，删除子图片中的除了目标区域的对象以外的其他对象，然后保留该子图片；当然，本发明实施例中不限于上述两种匹配方式。
举例来说，当得到的子图片中包括对象1、对象2、对象3和对象4，第一种匹配方式中，目标区域的对象1与子图片的对象1匹配成功时，删除子图片中的除了对象1以外的对象2、对象3和对象4，然后保留该子图片；另一种匹配方式中，目标区域的对象1、对象2和对象3与子图片的对象一一进行匹配，匹配成功后，删除子图片中的除了对象1、对象2和对象3以外的对象4，然后保留该子图片，这里，本发明实施例中的匹配方式不限于此；
这样，将用户不期望出现在视频中的对象删除掉，使得保留下的子图片都是用户期望的画面，从而提高了在拍照时所保存的前后时间段的图片的观赏性，提高用户体验。
S304：基于保留的各子图片生成视频数据，并将视频数据与拍照时刻所拍的照片进行保存。
在S303中得到了保留的各子图片之后，基于各子图片生成视频数据，视频数据的格式可以为video/avc，video/3gpp，video/mp4v-es等，照片的格式可以为bmp，jpg，tiff，gif，pcx，tga，exif，fpx，svg，psd，cdr，pcd，dxf，ufo，eps，ai，raw等，这里本发明实施例中对视频数据的格式与照片 的格式不做具体限定。
本发明实施例所提供的视频数据的生成方法，终端的相机运行时，首先，获取拍摄界面的目标区域并从目标区域的对象中确定出目标对象，然后在接收到拍照指令之后，以距离拍照时刻前预设时间处为起始时刻，以距离拍照时刻后预设时间处为结束时刻，按照预设步长获取各图片；其次，从每个图片中，截取出每个子图片，每个子图片中包括有目标对象且每个子图片的大小与目标区域的大小相同，这样，通过生成子图片，截取出局部的图片；最后，通过将目标区域分别与每个子图片进行匹配，得到保留的各子图片，并基于保留的各子图片生成视频数据，并将视频数据与拍照时刻所拍的照片进行保存，也就是说，本发明实施例中，通过截取出子图片，并将目标区域与每个子图片进行匹配，得到保留的各子图片，从而生成局部的视频数据，通过匹配使得该局部的视频数据中没有乱入的人或物，并且将该局部的视频数据与照片保存在一起，使得用户在观赏照片的同时可以观赏局部小视频，提高在拍照时所保存的前后时间段的视频的观赏性，提高用户体验。
基于前述的实施例，本发明实施例提供另一种视频数据的生成方法，该方法应配置为终端，该视频数据的生成方法所实现的功能可以通过终端中的处理器调用程序代码来实现，当然程序代码可以保存在计算机存储介质中，可见，该终端至少包括处理器和存储介质。
图6为本发明实施例另一种视频数据的生成方法的流程示意图，如图6所示，在上述实施例的基础上，S302可以包括：
S601：对每个图片进行检测，得到每个图片的对象；
S602：将每个图片的对象与目标对象进行匹配，当匹配成功时，保留匹配成功的图片，当匹配失败时，丢弃匹配失败的图片；
S603：从保留的每个图片中，确定出目标对象的位置信息；
S604：根据位置信息，从保留的每个图片中截取包括目标对象且与目标区域大小相同的区域，将截取的区域作为对应的子图片。
举例来说，在获取到每个图片之后，图7-1为本发明实施例的图片的一种可选的排布示意图，获取到的图片中如图7-1所示，首先对该图片进行检测得到该图片的对象包括：对象1、对象2、对象3、对象4、对象5和对象6，然后将上述对象分别与目标对象进行匹配，匹配成功说明该图片中存在目标对象，仍然以对象1为目标对象，通过匹配得知该图片中存在对象1，则保留该图片。
图7-2为本发明实施例图片的另一种可选的排布示意图，获取到的图片中如图7-2所示，首先对该图片进行检测得到该图片的对象包括：对象1、对象2、对象3、对象4、对象5和对象6，然后将上述对象分别与目标对象进行匹配，匹配成功说明该图片中存在目标对象，仍然以对象1为目标对象，通过匹配得知该图片中存在对象1，则保留该图片。
图7-3为本发明实施例图片的又一种可选的排布示意图，获取到的图片中如图7-3所示，首先对该图片进行检测得到该图片的对象包括：对象2、对象3、对象4、对象5和对象6，然后将上述对象分别与目标对象进行匹配，匹配成功说明该图片中存在目标对象，仍然以对象1为目标对象，通过匹配得知该图片中不存在对象1，则丢弃该图片。
经过上述检测和匹配得到了保留下来的图片，为了获取到目标对象的局部图片，从而得到目标对象的局部小视频，在具体实施过程中，从保留的每个图片中，确定出目标对象的位置信息，这里的位置信息为目标对象的在拍摄界面上的坐标信息；在确定了目标对象的位置信息之后，根据位置信息，在该图片上截取包括目标对象的子图片，并且该子图片的大小与目标区域的大小相同。至此，便得到了局部图片。
为了对保留下来的图片进行截取得到子图片，在一些实施例中，S604 可以包括：根据位置信息，设定目标对象的中心位置；以目标对象的中心位置为中心，从每个图片中截取与目标区域大小相同的区域。
终端在确定出目标对象的位置信息之后，为该目标对象设定出自身的中心位置。这里，该目标对象的中心位置可以是用户预先设置在终端中的，例如，在拍摄人物的时候，设定人物的头部为中心位置；然后以人物的头部为中心，从该图片中截取出与目标对象大小相同的区域。
举例来说，图7-4为本发明实施例二子图片的一种可选的排布示意图，图7-4的子图片是从图7-1的图片中截取出来的子图片，如图7-4所示，在获取到对象1之后，确定出对象1的位置信息，然后设定出对象1的中心位置，以对象1的中心位置为中心，截取出图7-4中的子图片，该子图片中包括对象1、对象2和对象3。
图7-5为本发明实施例子图片的另一种可选的排布示意图，图7-5的子图片是从图7-2的图片中截取出来的子图片，如图7-5所示，在获取到对象1之后，确定出对象1的位置信息，然后设定出对象1的中心位置，以对象1的中心位置为中心，截取出图7-5中的子图片，该子图片中包括对象1、对象2、对象3和对象4。
这样，对每个图片都做类似处理，便得到了各子图片。
在确定出子图片之后，为了满足用户的需求，在一些实施例中，在上述实施例一的基础上，S303可以包括：确定每个子图片的对象，将每个子图片的对象中目标对象以外的对象确定为第一特征对象集合；将目标区域的对象中目标对象以外的对象确定为第二特征对象集合；将第二特征对象集合与第一特征对象集合进行匹配，匹配成功时，保留子图片，匹配失败时，丢弃子图片。
其中，终端通过检测的方式，先确定出每个子图的对象和目标区域的对象，举例来说，仍然以图4的目标区域为例，则目标区域的对象为对象1 (人)、对象2(红色气球)和对象3(蓝色气球)，则第一特征对象的集合为红色气球和蓝色气球。
图7-4中的子图片的对象为人、红色气球和蓝色气球，那么第二特征对象集合为红色气球和蓝色气球，将图4中的红色气球和蓝色气球和图7-4中的红色气球和蓝色气球进行匹配，匹配成功，保留该子图片。
图7-5中的子图片的对象为对象人、红色气球、蓝色气球和对象4(鸟)，那么第二特征对象集合为红色气球、蓝色气球和鸟，将图4中的红色气球和蓝色气球和图7-5中的红色气球、蓝色气球和鸟进行匹配，匹配成功，保留该子图片，图7-5中的鸟未找到匹配对象，则删除鸟，保留该图片。
图7-6为本发明实施例子图片的又一种可选的排布示意图，如图7-6所示，图7-6中的子图片的对象为对象人和蓝色气球，那么第二特征对象集合为蓝色气球，将图4中的红色气球和蓝色气球和图7-6中的蓝色气球进行匹配，由于图4中的红色气球未找到匹配对象，匹配失败，丢弃该子图片。
由上述可以得到制作局部小视频的局部图片。
这里，这里需要说明的是，上述目标区域为闭合区域。
基于前述的方法实施例，本实施例提供一种终端，该终端中的获取单元和确定单元，以及各单元各自所包括的各模块，都可以通过终端中的处理器，可以理解为图1中的控制器180，来实现，当然也可通过具体的逻辑电路实现；在具体实施例的过程中，处理器可以为中央处理器(CPU)、微处理器(MPU)、DSP或FPGA等。
