背景技术
近年来随着终端(如手机)软硬件的快速发展，终端拍摄已经成为用户日常使用的一个重要场景，而拍照时因为抖动导致的画面模糊问题，也亟待改善。
在相关技术中，主要有两种终端拍摄的防抖技术：第一种是通过配置带硬件防抖功能的摄像头，由摄像头模组中的防抖器件来改善镜头的抖动问题；第二种是通过提高成像传感器的增益设置，缩短拍摄的快门时间，从而起到减少抖动的作用。
对于第一种防抖技术，由于带硬件防抖功能的摄像头模组成本很高，且物理尺寸通常较大，因而会影响终端的硬件成本及结构设计；对于第二种防抖技术，由于增大成像传感器的增益，在缩短快门时间的同时也会导致成像噪点的增加，对成像效果会有较明显的影响。因而，相关技术中的终端拍照的防抖功能有限，因而，用户拍照的体验度较差。

上述预定阈值可以是预先进行设定的，在一个优选实施例中，该预定阈值可以设置成大，中，小三个档位，用户可以根据不同的需求选择不同的档位。
在本发明实施例中，步骤S202可以包括以下至少之一：在预定时间段内通过终端的传感器获取抖动信息；或者，在预定时间段内对终端的当前待拍摄画面的多个区域的运动矢量进行平均处理，得到第二抖动信息。
上述传感器可以是加速度传感器，也可以是陀螺仪，在抖动信息为加速度时，上述传感器为加速度传感器，在在抖动信息为旋转加速度时，上述传感器为陀螺仪；上述运动矢量可以通过以下方法计算获取，但不限于此：将当前拍摄画面按比例划分8*8块区域，每个角上各取4块，共16块区域，先进行灰度投影，再计算对比度均值，使用该值作为抖动信息的参考值，对比度高则认为抖动小，对比度低则认为抖动大。
在本发明实施例中，在在预定时间段内获取终端的多个第一抖动信息以及多个第一抖动信息对应的成像数据之前，方法还包括：接收开启终端的防抖拍摄优化功能的指令。
需要说明的是，如果未开启防抖拍摄优化功能，则在拍摄时，不监控终端的抖动信息。
为了更好的理解上述方法实施例，以下结合优选的方法实施例对上述方法实施例做进一步的解释：
以手机拍照为例，本发明提供了一种优选的终端的拍照方法，该方法包括以下步骤：
当用户在使用手机进行拍照时，系统会持续监控手机的抖动状态(即上述实施例中的抖动信息)，当手机抖动状态小于用户设定的阈值时候，直接进行拍照输出，当在设定时限内抖动状态一直大于用户设定阈值时候，则选择监控时段内抖动状态最小时刻的成像数据输出。通过该优选的实施例可以获取较好的成像效果，改善手机拍照体验。
具体的，上述优选的方法实施例可以包括以下步骤：
步骤S301，防抖优化的参数设置，图3是本发明优选实施例的防抖优选功能的参数设置的示意图，如图3所示，包括：
步骤S3011:设置是否开启防抖优化功能；
步骤S3012:设置抖动阈值(可提供大，中，小三种选项，供用户选择，默认为中)；
步骤S3013:设置防抖时延(可提供0.5秒、1秒、2秒等选项，供用户选择，默认为1秒)；
需要说明的是，上述设置均持久化存储到移动终端系统中。
步骤S302：监控手机抖动信息；
1).未开启防抖拍摄优化功能时
在进行拍摄时，不监控手机抖动信息。
2).开启防抖拍摄优化功能时
步骤S3021:当用户在设置单元中设定开启优化功能时，在用户按下拍照键后的设定时段内，对手机抖动信息进行监控记录。图4是本发明优选实施例的抖动信息获取方式的示意图，如图4所示，抖动信息可以通过硬件方式获取，也可以通过软件方式获取，
若手机配备了陀螺仪/加速度传感器，由传感器提供抖动信息，即通过硬件方式获取抖动信息。若手机未配备陀螺仪/加速度传感器，则通过对画面四角区域的运动矢量做平均处理得出抖动信息，即通过软件方式获取抖动信息。
运动矢量的计算可以采用以下方法，但不仅限于该方法：将画面按比例划分8*8块区域，每个角上各取4块，共16块区域，先进行灰度投影，再计算对比度均值，使用该值作为抖动信息的参考值，对比度高则认为抖动小，对比度低则认为抖动大。
步骤S303：执行防抖拍摄相关处理；
1).未开启防抖拍摄优化功能时
在进行拍摄时，不做防抖优化处理。
2).开启防抖拍摄优化功能时
当用户在设置单元中设定开启优化功能时，防抖拍摄优化执行单元会在用户按下拍照键后，到设定时延的时段内，按照其相关设置项进行防抖优化处理。图5是本发明优选实施例的终端的拍照方法的流程图，如图5所示，包括以下步骤：
步骤S3031：当用户按下拍照键后，开始获取当前手机抖动信息(即上述实施例中的第二抖动信息)。
步骤S3032：如果抖动信息小于用户设定的阈值，则直接将当前成像数据输出，直接完成拍摄动作。
步骤S3033：如果抖动信息大于用户设定的阈值，则将当前抖动信息(相当于上述实施例中的第一抖动信息)及成像数据，暂存到备选队列中。
重复执行步骤S3031，S3032，S3033至设定的时延。
步骤S3034：如果直到设定时延，抖动信息始终大于用户设定的阈值，则在暂存的备选队列，选择抖动信息最小的那张成像数据作为输出，完成拍摄动作。
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更佳的实施方式。基于这样的理解，本发明的技术方案本质上或者说对现有技术做出贡 献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括若干指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明各个实施例所述的方法。
在本实施例中还提供了一种终端的拍照装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
图6是根据本发明实施例的终端的拍照装置的结构框图一，如图6所示，该装置包括：
获取模块62，设置为在预定时间段内获取终端的多个第一抖动信息以及多个第一抖动信息对应的成像数据；
比较模块64，设置为比较多个第一抖动信息，得到抖动最小的第一抖动信息；

通过上述装置，采用在预定时间段内获取终端的多个第一抖动信息以及多个第一抖动信息对应的成像数据；比较多个第一抖动信息，得到抖动最小的第一抖动信息；输出最小的第一抖动信息对应的成像数据，即通过输出该预定时间段内的抖动最小的第一抖动信息对应的成像数据，解决了相关技术中，终端实现拍照的防抖功能成本高，用户拍照体验度差的问题，进而提高了终端的成像效果，提高了用户的拍照体验。
需要说明的是，上述预定时间段可以是防抖时延，该预定时间段可以通过终端内部的设置进行自行选择，也可以用户根据自己的需求进行设定，也可以两者结合进行选择，在一个优选的实施例中，终端中可以预先设定三个选项：0.5秒选项、1秒选项、2秒选项，用户可以根据自己的需要选择预定时间段为0.5秒选项、1秒选项或者2秒选项。
上述第一抖动信息可以包括以下至少之一：终端的加速度，所述终端的旋转加速度，终端的当前待拍摄画面的对比度；其中，加速度的大小与终端的抖动成正比，即终端的加速度大则终端的抖动大，加速度小则抖动小；旋转加速度的大小与终端的抖动成正比，即终端的旋转加速度大则终端的抖动大，旋转加速度小则抖动小；对比度的高低与终端的抖动成反比，即当前拍摄画面的对比度高则终端的抖动小，对比度低则抖动大。
上述获取模块62，还设置为在预定时间段内获取终端的第二抖动信息；以及在第二抖动信息超过预定阈值的情况下，确定第二抖动信息为第一抖动信息。
需要说明的是，上述第一抖动信息是第二抖动信息的一种，即超过预定阈值的第二抖动信息可以称之为第一抖动信息，因而，第二抖动信息所包含的内容与上述第一抖动信息所包含的内容实质上应当是相同的。
上述预定阈值可以是预先进行设定的，在一个优选实施例中，该预定阈值可以设置成大，中，小三个档位，用户可以根据不同的需求选择不同的档位。
在本发明实施例中，图7是根据本发明实施例的终端的拍照装置的结构框图二，如图7所示，上述获取模块62包括：第一获取单元622，设置为在预定时间段内通过终端的传感器获取抖动信息；第二获取单元624，设置为在预定时间段内对终端的当前待拍摄画面的多个区域的运动矢量进行平均处理，得到第二抖动信息。
上述传感器可以是加速度传感器，也可以是陀螺仪，在抖动信息为加速度时，上述传感器为加速度传感器，在在抖动信息为旋转加速度时，上述传感器为陀螺仪；上述运动矢量可以通过以下方法计算获取，但不限于此：将当前拍摄画面按比例划分8*8块区域，每个角上各取4块，共16块区域，先进行灰度投影，再计算对比度均值，使用该值作为抖动信息的参考值，对比度高则认为抖动小，对比度低则认为抖动大。
在本发明实施例中，装置还包括：接收模块，设置为在在预定时间段内获取终端的多个第一抖动信息以及多个第一抖动信息对应的成像数据之前，接收开启终端的防抖拍摄优化功能的指令。
需要说明的是，如果未开启防抖拍摄优化功能，则在拍摄时，不监控终端的抖动信息。

需要说明的是，上述防抖功能设置单元82可以设置为完成图3所示的参数设置的方法实施例，抖动检测单元84可以设置为完成图4所示的监控手机抖动信息的功能；防抖拍摄执行单元86可以设置为完成图5所示的执行防抖拍摄功能。该优选实施例中的防抖拍摄执行单元86与上述第一获取模块62、比较模块64、输出模块66完成的功能部分相同。
需要说明的是，上述各个模块是可以通过软件或硬件来实现的，对于后者，可以通过以下方式实现，但不限于此：上述模块均位于同一处理器中；或者，上述模块分别位于多个处理器中。
本发明的实施例还提供了一种存储介质。可选地，在本实施例中，上述存储介质可以被设置为存储用于执行以下步骤的程序代码：
