至此，已经按照其功能描述了移动终端100。下面，为了简要起见，将描述诸如折叠型、直板型、摆动型、滑动型移动终端100等等的各种类型的移动终端100中的滑动型移动终端100作为示例。因此，本发明能够应用于任何类型的移动终端100，并且不限于滑动型移动终端100。
如图1中所示的移动终端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100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己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 2750。
每个BS 270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，每个分区可以由用于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BT295发送的广播信号。在图2中，示出了几个卫星300，例如可以采用全球定位系统(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GPS模块115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100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。特定基站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。BSC275还将接收到的数据路由到MSC 280，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。
移动终端中无线通信单元110的移动通信模块112基于移动终端内置的接入移动通信网络(如2G/3G/4G等移动通信网络)的必要数据(包括用户识别信息和鉴权信息)接入移动通信网络为移动终端用户的网页浏览、网络多媒体播放等业务传输移动通信数据(包括上行的移动通信数据和下行的移动通信数据)。
无线通信单元110的无线互联网模块113通过运行无线热点的相关协议功能而实现无线热点的功能，无线热点支持多个移动终端(移动终端之外的任意移动终端)接入，通过复用移动通信模块112与移动通信网络之 间的移动通信连接为移动终端用户的网页浏览、网络多媒体播放等业务传输移动通信数据(包括上行的移动通信数据和下行的移动通信数据)，由于移动终端实质上是复用移动终端与通信网络之间的移动通信连接传输移动通信数据的，因此移动终端消耗的移动通信数据的流量由通信网络侧的计费实体计入移动终端的通信资费，从而消耗移动终端签约使用的通信资费中包括的移动通信数据的数据流量。
基于上述移动终端100硬件结构以及通信系统，提出本发明方法各个实施例。
实施例一
本实施例提供了一种图像处理方法；这里，采用本实施例所述的图像处理方法，在视频拍摄过程中，若出现手抖导致画面位置发现变化的情况时，会将变化的像素点拉回到变化之前标定的位置，从而使视频画面不会晃动，达到画面稳定的效果；例如，用户利用手机对演唱会现场进行视频拍摄时，可以利用演唱会现场中处于静止状态的背景作为参考点，并基于背景中变化的像素点，对视频帧拉回到原有位置，而演唱会现场中的移动物体正常移动，如此，保证正常采集的前提下，避免了由于抖动而导致的视频图像模糊的问题。
具体地，图3为本发明实施例一图像处理方法的实现流程示意图，如图3所示，该图像处理方法包括：
步骤301：电子设备利用图像采集装置采集视频数据；
本实施例中，所述图像采集装置可以具体为设置于所述电子设备中的摄像头，例如，手机中的前置或后置摄像头；也可以具体为与电子设备连接的外置摄像头。
步骤302：将采集到的视频数据中的第一视频帧确定为参考图像；所述第一视频帧为所述电子设备中呈现的针对所述视频数据的预览图像；
本实施例中，所述第一视频帧并非具体指所述视频数据中的第一帧图像；而是指所述视频数据中的任一帧视频图像；对应地，所述参考图像可以具体为采集到的所述视频数据中的任一视频帧对应的图像，例如，如图4所示，所述电子设备在取景界面实时呈现采集到的视频数据，此时，所述电子设备可以自动确定出参考图像，如自动将采集视频数据时所对应的第一帧图像确定为所述参考图像；或者，所述参考图像为电子设备基于预设规则，在采集到的视频数据中所筛选出的某一视频帧。当然，在实际应用中，所述参考图像还可以是基于用户操作而选取出的，例如，如图5所示，当所述电子设备在取景界面呈现实时采集到的视频数据时，所述电子设备可以基于用户的触控操作选取出参考图像，并将选取出的参考图像呈现于显示区域的部分区域中，如将所述参考图像呈现在所述显示区域的右下角，以便于用户能够观察到该截取的图像，为及时更换所述参考图像提供了便利条件。
进一步地，在实际应用中，为使所述电子设备存储的视频数据中的视频帧即为调整后的视频帧，所述电子设备可以在确定出参考图像后才开始存储视频数据，而存储视频数据之前的采集过程仅为确定参考图像而服务，并不会被存储，这样，能够有效避免存储的视频数据中存在视频图像模糊的问题，为提供用户体验奠定了基础。
步骤303：从所述参考图像中选取出参考区域，并确定出所述参考区域中像素点对应的第一组坐标信息；
在一实施例中，当所述电子设备确定出参考图像后，还需要在所述参考图像中选取出参考区域；这里，为便于对视频帧进行调整，可以从采集到的视频数据对应的实体场景中选取固定目标体对应的区域；具体地，所述电子设备从所述参考图像中选取出固定目标体对应的区域；这里，所述固定目标体为所述视频数据对应的采集区域中所述电子设备采集到的处于 固定状态(也即静止状态)的目标体；进而所述电子设备将所述参考图像中所述固定目标体对应的区域作为参考区域，比如，将演唱会现场中处于固定状态的背景对应的区域设置为参考区域。这样，由于选取出的参考区域为固定物体对应的区域，所以，对于相邻两个视频帧而言，在视频采集过程中，可以认定相邻两个视频帧中该固定物体的坐标不变，进而当与参考图像对应的下一视频帧中的固定物体的坐标发生变化时，可以利用所述参考图像中所述固定物体的坐标来对该下一视频帧进行调整，如此，避免视频图像模糊。而且，由于选取的参考区域为固定物体对应的区域，所以，调整算法复杂度较，便于在电子设备中实现。
当然，在实际应用中，还可以从采集到的视频数据对应的实体场景中选取移动目标体中的固定部分对应的区域，进而将所述参考图像中所述移动目标体中的固定部分对应的区域作为参考区域。这里，为匹配不同的算法复杂度，参考区域的选取过程可以根据实际情况而任意确定。
在另一实施例中，所述电子设备可以基于所述参考图像中所述参考区域对应的像素点的像素特征，从所述参考图像的参考区域中选取出目标像素点，也就是说，在实际应用中，并非将确定出的参考图像的参考区域中的所有像素点均作为参考像素点，而是从中选取出部分像素点作为目标像素点，例如选取出灰度变化明显的像素点作为目标像素点，进而确定出所述目标像素点对应的坐标信息，并将所述目标像素点对应的坐标信息作为第一组坐标信息，进而降低调整算法复杂度。
步骤304：利用所述第一组坐标信息对采集到的视频数据中的视频帧进行调整，以使调整后的视频帧中所述参考区域对应的像素点的第二组坐标信息与所述第一组坐标信息相对应；
在实际应用中，可以将采集到的视频数据中每一视频帧的所述参考区域对应的像素点与第一组坐标信息对应的像素点进行比对，进而确定出相 关联的像素对，进而基于相关联的像素对确定对视频帧进行调整的调整方式。
步骤305：存储调整后的视频帧，并基于存储的调整后的视频帧组合成针对采集到的所述视频数据的目标视频数据。
这样，本发明实施例所述的方法，通过在采集视频数据中确定参考图像，并从所述参考图像中选取出参考区域，进而利用所述参考区域中像素点对应的第一组坐标信息对采集到的视频数据中的视频帧进行调整，使调整后的视频帧中所述参考区域对应的像素点的第二组坐标信息与所述第一组坐标信息相对应，如此，实现对采集到的视频数据进行实施调整的目的；而且，所述电子设备并非直接对采集得到的视频数据进行存储，而是存储调整后的视频帧以组合成针对采集到的所述视频数据的目标视频数据，这样，避免了由于抖动而是存储的视频图像模糊的问题，提升了用户体验。
实施例二
本实施例提供了一种图像处理方法；这里，采用本实施例所述的图像处理方法，在视频拍摄过程中，若出现手抖导致画面位置发现变化的情况时，会将变化的像素点拉回到变化之前标定的位置，从而使视频画面不会晃动，达到画面稳定的效果；例如，用户利用手机对演唱会现场进行视频拍摄时，可以利用演唱会现场中处于静止状态的背景作为参考点，并基于背景中变化的像素点，对视频帧拉回到原有位置，而演唱会现场中的移动物体正常移动，如此，保证正常采集的前提下，避免了由于抖动而导致的视频图像模糊的问题。
具体地，图6为本发明实施例二图像处理方法的实现流程示意图，如图6所示，该图像处理方法包括：
步骤601：电子设备利用图像采集装置采集视频数据；
本实施例中，所述图像采集装置可以具体为设置于所述电子设备中的 摄像头，例如，手机中的前置或后置摄像头；也可以具体为与电子设备连接的外置摄像头。
步骤602：将采集到的视频数据中的第一视频帧确定为参考图像；所述第一视频帧为所述电子设备中呈现的针对所述视频数据的预览图像；
本实施例中，所述第一视频帧并非具体指所述视频数据中的第一帧图像；而是指所述视频数据中的任一帧视频图像；对应地，所述参考图像可以具体为采集到的所述视频数据中的任一视频帧对应的图像，例如，如图4所示，所述电子设备在取景界面实时呈现采集到的视频数据，此时，所述电子设备可以自动确定出参考图像，如自动将采集视频数据时所对应的第一帧图像确定为所述参考图像；或者，所述参考图像为电子设备基于预设规则，在采集到的视频数据中所筛选出的某一视频帧。当然，在实际应用中，所述参考图像还可以是基于用户操作而选取出的，例如，如图5所示，当所述电子设备在取景界面呈现实时采集到的视频数据时，所述电子设备可以基于用户的触控操作选取出参考图像，并将选取出的参考图像呈现于显示区域的部分区域中，如将所述参考图像呈现在所述显示区域的右下角，以便于用户能够观察到该截取的图像，为及时更换所述参考图像提供了便利条件。
进一步地，在实际应用中，为使所述电子设备存储的视频数据中的视频帧即为调整后的视频帧，所述电子设备可以在确定出参考图像后才开始存储视频数据，而存储视频数据之前的采集过程仅为确定参考图像而服务，并不会被存储，这样，能够有效避免存储的视频数据中存在视频图像模糊的问题，为提供用户体验奠定了基础。
步骤603：从所述参考图像中选取出参考区域，并确定出所述参考区域中像素点对应的第一组坐标信息；
在一实施例中，当所述电子设备确定出参考图像后，还需要在所述参 考图像中选取出参考区域；这里，为便于对视频帧进行调整，可以从采集到的视频数据对应的实体场景中选取固定目标体对应的区域；具体地，所述电子设备从所述参考图像中选取出固定目标体对应的区域；这里，所述固定目标体为所述视频数据对应的采集区域中所述电子设备采集到的处于固定状态(也即静止状态)的目标体；进而所述电子设备将所述参考图像中所述固定目标体对应的区域作为参考区域，比如，将演唱会现场中处于固定状态的背景对应的区域设置为参考区域。这样，由于选取出的参考区域为固定物体对应的区域，所以，对于相邻两个视频帧而言，在视频采集过程中，可以认定相邻两个视频帧中该固定物体的坐标不变，进而当与参考图像对应的下一视频帧中的固定物体的坐标发生变化时，可以利用所述参考图像中所述固定物体的坐标来对该下一视频帧进行调整，如此，避免视频图像模糊。而且，由于选取的参考区域为固定物体对应的区域，所以，调整算法复杂度较，便于在电子设备中实现。
当然，在实际应用中，还可以从采集到的视频数据对应的实体场景中选取移动目标体中的固定部分对应的区域，进而将所述参考图像中所述移动目标体中的固定部分对应的区域作为参考区域。这里，为匹配不同的算法复杂度，参考区域的选取过程可以根据实际情况而任意确定。
在另一实施例中，所述电子设备可以基于所述参考图像中所述参考区域对应的像素点的像素特征，从所述参考图像的参考区域中选取出目标像素点，也就是说，在实际应用中，并非将确定出的参考图像的参考区域中的所有像素点均作为参考像素点，而是从中选取出部分像素点作为目标像素点，例如选取出灰度变化明显的像素点作为目标像素点，进而确定出所述目标像素点对应的坐标信息，并将所述目标像素点对应的坐标信息作为第一组坐标信息，进而降低调整算法复杂度。
步骤604：确定采集到所述视频数据的每一视频帧中所述参考区域对应 的像素点的第二组坐标信息；
在实际应用中，可以将采集到的视频数据中每一视频帧的所述参考区域对应的像素点与第一组坐标信息对应的像素点进行比对，进而确定出相关联的像素对，进而基于相关联的像素对确定对视频帧进行调整的调整方式。
本实施例中，采集到的视频数据是基于同一实体场景的，例如，对演唱会现场进行采集，所以，在确定出参考区域后，随后采集的视频数据的每一视频帧中均对应有该参考区域，因此，可以利用不同视频帧(如参考图像与每一视频帧)中的同一参考区域在相同坐标下坐标的变化值来确定两帧图像的位置关系，进而基于该位置关系确定出调整方式。这里，所述第二组坐标信息即为同一视频数据中的与参考图像不同的视频帧中所述参考区域对应的像素点的坐标信息。
步骤605：基于所述第一组坐标信息以及每一视频帧对应的第二组坐标信息，确定所述参考图像与每一视频帧的位置关系；
在一具体实施例中，所述第一组坐标信息中至少包含有两个第一坐标；所述第二组坐标信息中至少包括有两个第二坐标；对应的，步骤605具备包括：
从所述至少两个第一坐标以及所述至少两个第二坐标中，选取出像素特征相匹配的至少两组坐标对；所述坐标对中包括有像素特征相匹配的一个第一坐标和一个第二坐标；这里，所述像素特征相匹配指的是不同视频帧中的同一像素点像素特征相匹配，例如，参考图像中的参考区域的第一像素点与某一视频帧中该参考区域的同一第一像素点，此两个第一像素点的像素特征相匹配，能够组合成一个坐标对。进一步地，所述电子设备基于至少两组坐标对，确定所述参考图像与每一视频帧的位置关系。这里，当用户抖动而使得电子设备抖动时，同一像素点在同一坐标系下的坐标必 然会发生变化，所以，本实施例利用了该变化特征来确定参考图像与任一视频帧之间的位置关系，进而基于位置关系，对每一视频帧进行调整。
步骤606：根据所述位置关系对采集到的视频数据中的视频帧进行调整；
步骤607：存储调整后的视频帧，并基于存储的调整后的视频帧组合成针对采集到的所述视频数据的目标视频数据。
这样，本发明实施例所述的方法，通过在采集视频数据中确定参考图像，并从所述参考图像中选取出参考区域，进而利用所述参考区域中像素点对应的第一组坐标信息对采集到的视频数据中的视频帧进行调整，使调整后的视频帧中所述参考区域对应的像素点的第二组坐标信息与所述第一组坐标信息相对应，如此，实现对采集到的视频数据进行实施调整的目的；而且，所述电子设备并非直接对采集得到的视频数据进行存储，而是存储调整后的视频帧以组合成针对采集到的所述视频数据的目标视频数据，这样，避免了由于抖动而是存储的视频图像模糊的问题，提升了用户体验。
以下通过具体应用场景对本发明实施例做进一步详细说明；具体地，所述电子设备开启相机，并选择视频模式；随后，如图7所示，
步骤701：所述电子设备从预览画面中截取参考图像，并确定出参考区域。
在实际应用中，电子设备进入视频模式后，用户会选择一个要拍的景物，预览界面中包含用户预要拍摄的景物和角度。此时，点击拍摄，电子设备会截取一张预览照片，将该预览图像作为参考图像，同时，选取出该参考图像的参考区域。
步骤702：当确定出参考区域后，可以在参考区域中选取出特征显著的像素点作为目标像素点，进而将目标像素点的坐标作为第一组坐标信息，以用于后续的图像配准。
这里，可以根据要拍摄的景物的特征，选取区域(森林、湖泊、农田等)、线(区域的边界、道路等)或点(区域的角点、线的交点、曲线上的高曲率点等)等的像素作为目标像素点；这里，提取出的目标像素点可以分布在图像任何地方。
当然，在实际应用中，在确定目标像素点的时候还可以参考像素特征变化特征，如灰度变化情况，具体地，可以将参考区域中灰度变化明显的点、线、区域等对应的像素点作为目标像素点；
步骤703：确定采集到的视频数据中每一帧对应的所述参考区域中的所述目标像素点的坐标信息，得到第二组坐标信息，基于所述第一组坐标信息以及每一视频帧对应的第二组坐标信息，选取出像素特征相匹配的坐标对；
这里，在两幅图像(参考图像与任一视频帧对应的图像)对应的坐标组中利用特征匹配算法确定出像素特征匹配的坐标对，当然，对于像素特征不匹配的像素点对应的坐标可以删除，也可以利用插值等方法推算出对应的坐标，从而实现两幅图像之间逐像素的配准。
步骤704：基于由所述第一组坐标信息与视频数据中的每一视频帧对应的第二组坐标信息形成的坐标对，确定出所述参考图像与视频数据中的每一视频帧的位置关系；
这里，该位置关系可以具体为空间变化模型，即两幅要配准的图像(如参考图像与每一视频帧)之间的映射模型，比如两图像旋转、平移后即会重合，此时模型为刚体变换模型，又比如需要缩放，甚至X方向和Y方向缩放的幅度都一样，此时，模型即为仿射变换或者非线性变换模型。
具体地，比如视频数据中的某一视频帧为图像A，将A左移2个像素，下移3个像素，再顺时针旋转60度后，得到图像B，假设图像B为参考图像。此时，对A和B进行配准的过程就是确定2、3、60这三个参数的过程， 因为这三个参数一旦确定了，就能够得到图像B和图像A的对应关系。当然，在实际应用中，难以直接确定出上述三个参数，因此，可以将两幅图像重合的像素最多的那组参数确定为变化参数。例如，对这三个参数的解空间进行遍历，比如对X方向的平移像素个数从-100搜索到+100，步距为1像素，对Y方向的平移像素也从-100搜索到+100，步距为1像素，对旋转角度从0搜索到360度，步距为1度，以完成一个200*200*360次的循环，然后在每次循环中，确定当次循环参数进行变换后的图像A与图像B的重合像素的个数，找出200*200*360次循环中重合像素个数最多的那组循环中所使用的参数，该参数即可为变化参数。
步骤705：基于位置关系对视频数据中的每一视频帧进行调整。
当然，在实际应用中可以根据实际需求选取变化方法，只要能够对视频帧进行校准即可。这里，以最近邻插值为例，对调整过程做详细说明；
假设目的像素，也即待调整视频帧中目标像素的坐标为F(x1，y1)，此时可以通过反向变换方法得到在该目标像素在参考图像上的对应值浮点坐标P(u，v)，这里，可以利用步骤704得到的位置关系，如利用2、3、60三个参数，将(x1，y1)反向调整，得到所述参考图像上该目标像素的坐标点，即坐标P(u，v)。这里，在实际应用中，u，v可能会为小数，而实际图像中并未有坐标为小数的点对应的像素点，所以，需要对确定出的浮点坐标P(u，v)做进一步调整，如图8所示，利用近邻插值公式对P(u，v)进行调整，具体地，可以对(u+0.5)进行取整得到m，对(v+0.5)进行取整得到v，进而确定出像素点(m，n)、(m+1，n)、(m，n+1)、(m+1，n+1)，并确定出(m，n)、(m+1，n)、(m，n+1)、(m+1，n+1)分别与P(u，v)的像素值的差值，将差值最小的像素点作为(x1，y1)调整后所对应的点，如差值最小的点为(m，n)，则坐标g(m，n)即为(x1，y1)调整后所对应的点；这里，坐标g(m，n)即可认定为对应于参考图像上 的坐标。
这样，即可提高视频流畅程度，提升电子产品的竞争力。这里，值得注意的是，本实施例仅适用于拍摄场景不变的情况，而不适用场景变换的情况
