具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例中所描述的终端具体可以是具备双摄像头的智能手机、平板电脑、移动互联网设备（mobile internet device，MID）以及智能可穿戴设备等。
请参阅图1，为本发明实施例提供的一种图像处理方法的第一实施例流程示意图。本实施例中所描述的图像处理方法，包括以下步骤：
101、终端在检测到输入的拍照指令时，利用第一摄像头捕获预设第一数量帧图像。
具体的，用户可以通过触摸操作/按压物理按键/语音控制/手势控制等方式输入拍照指令，该终端在检测到该用户输入的该拍照指令时，利用该第一摄像头连续地捕获预设第一数量帧图像，其中，该预设第一数量例如可以为3，即该终端利用该第一摄像头连续地捕获3帧图像。
102、所述终端利用第二摄像头捕获预设第二数量帧图像。
具体实现中，该终端可以在利用该第一摄像头捕获到该预设第一数量帧图像中的最后一帧图像时，再利用该第二摄像头连续地捕获预设第二数量帧图像，其中，该预设第二数量例如可以为6，即该终端利用该第一摄像头捕获到该3帧图像中的第3帧图像时，利用该第二摄像头连续地捕获6帧图像。
103、所述终端利用预设算法对所述预设第一数量帧图像和所述预设第二数量帧图像进行合成处理。
其中，该预设算法具体可以是线性叠加合成算法。
具体的，该终端可以利用线性叠加合成算法将该预设第一数量帧图像与该预设第二数量帧图像合成，以得到拍照图像。
其中，该第一摄像头和该第二摄像头中，可以一个为普通摄像头，另一个为广角摄像头。本发明实施例中可以是该第一摄像头为普通摄像头，该第二摄像头为广角摄像头。
在一些可行的实施方式中，该终端在利用该第一摄像头连续地捕获该预设第一数量帧图像的过程中，可以实时地对捕获到的图像进行解析，确定捕获到的图像存在拖影模糊的区域，进而该终端在利用该第二摄像头捕获该预设第二数量帧图像时，可以将焦点自动对焦到上述拖影模糊区域对应的拍照对象，以通过该第二摄像头捕获上述拖影模糊区域对应的拍照对象的清晰图像，从而通过图像合成可以消除上述拖影模糊区域。
可以理解的是，根据对通过图像合成得到的拍照图像的效果的不同需求，可以采用其它类型的算法进行图像合成，本发明实施例不做限定。
需要说明的是，对于该预设第一数量与该预设第二数量之间的大小关系不做限制，考虑到对该预设第一数量帧图像和该预设第二数量帧图像进行像合成处理需要时间，为保证用户获得良好的拍照体验，在输入拍照指令后可以及时看到拍照图像，可以限制该预设第一数量与该预设第二数量的总和不得超过预设数值，例如，该预设第一数量与该预设第二数量的总和不超过9，上述仅是以该预设第一数量为3，该预设第二数量为6举例，当然，也可以是该预设第一数量为6，该预设第二数量为3，等等。
本发明实施例中，终端在检测到输入的拍照指令时，利用第一摄像头捕获预设第一数量帧图像，并利用第二摄像头捕获预设第二数量帧图像，再利用预设算法对该预设第一数量帧图像和该预设第二数量帧图像进行合成处理，得到合成图像，可以消除拍照时图像的拖影模糊现象，提升拍照图像的质量。
请参阅图2，为本发明实施例提供的一种图像处理方法的第二实施例流程示意图。本实施例中所描述的图像处理方法，包括以下步骤：
201、终端在检测到输入的拍照指令时，利用第一摄像头捕获预设第一数量帧图像。
具体的，用户可以通过触摸操作/按压物理按键/语音控制/手势控制等方式输入拍照指令，该终端在检测到该用户输入的该拍照指令时，利用该第一摄像头连续地捕获预设第一数量帧图像，其中，该预设第一数量例如可以为3，即该终端利用该第一摄像头连续地捕获3帧图像。
同时，该终端在利用该第一摄像头连续地捕获该预设第一数量帧图像时，可以利用重力传感器、陀螺仪等获取并记录该终端捕获该终端捕获该预设第一数量帧图像中的每一帧图像时该终端的抖动程度，该终端抖动程度例如可以通过三维坐标系X、Y、Z三个方向上的加速度表示。
202、所述终端获取在利用所述第一摄像头捕获所述预设第一数量帧图像中的第一帧图像时，所述终端的抖动程度。
203、所述终端判断所述终端的抖动程度是否大于或等于预设第一抖动程度，若是，则执行步骤204；若否，则执行步骤205。
其中，该预设第一抖动程度具体可以是对图像清晰度影响较大时的抖动程度，其具体值可以根据实际需求灵活调整，本发明实施例不做限定。
具体的，该终端获取预先记录的在利用该第一摄像头捕获该预设第一数量帧图像中的第一帧图像时，该终端的抖动程度，并与该预设第一抖动程度进行比较，如果大于或等于该预设第一抖动程度，则执行步骤204；如果小于该预设第一抖动程度，则执行步骤205。
204、所述终端在经历预设时长后，利用第二摄像头捕获预设第二数量帧图像。
具体的，该终端在利用该第一摄像头捕获该预设第一数量帧图像中的第一帧图像时，如果该终端的抖动程度大于或等于该预设第一抖动程度，即该终端抖动较严重时，可以等待预设时长后，再利用该第二摄像头捕获该预设第二数量帧图像，可以通过延迟一段时间，尽可能避开在该终端抖动较严重时利用该第二摄像头捕获该预设第二数量帧图像。
其中，对于该预设时长的选择，例如可以是该终端利用该第一摄像头捕获该预设第一数量帧图像所经历的时长，即在该终端利用该第一摄像头捕获该预设第一数量帧图像中的第一帧图像时，如果该终端的抖动程度大于或等于该预设第一抖动程度，则该终端在利用该第一摄像头捕获到该预设第一数量帧图像中的最后一帧图像时，利用该第二摄像头连续地捕获预设第二数量帧图。对于该预设时长的选择，本发明实施例不做限定。
在一些可行的实施方式中，该终端等待该预设时长后，也可以获取此时该终端的抖动程度，如果此时的该终端的抖动程度小于该预设第一抖动程度，则该终端才利用该第二摄像头捕获该预设第二数量帧图像。
205、所述终端利用所述第二摄像头捕获所述预设第二数量帧图像。
具体的，该终端在利用该第一摄像头捕获该预设第一数量帧图像中的第一帧图像时，如果该终端的抖动程度小于该预设第一抖动程度，即该终端抖动较轻微或者没有抖动时，可以立即利用该第二摄像头连续地捕获该预设第二数量帧图像。
同样地，该终端在利用该第二摄像头连续地捕获该预设第二数量帧图像时，可以利用重力传感器、陀螺仪等获取并记录该终端捕获该终端捕获该预设第二数量帧图像中的每一帧图像时该终端的抖动程度，该终端抖动程度例如可以通过三维坐标系X、Y、Z三个方向上的加速度表示。
206、所述终端获取记录的在捕获所述预设第一数量帧图像中的每一帧图像时，所述终端的抖动程度，以及获取记录的在捕获所述预设第二数量帧图像中的每一帧图像时，所述终端的抖动程度。
207、所述终端确定所述预设第一数量帧图像中对应所述终端的抖动程度小于或等于预设第二抖动程度的第一图像，以及确定所述预设第二数量帧图像中对应所述终端的抖动程度小于或等于预设第三抖动程度的第二图像。
其中，该预设第二抖动程度和该预设第三抖动程度可以分别根据该第一摄像头和该第二摄像头的性能参数确定，该预设第二抖动程度和该预设第三抖动程度可以相等，也可以不等。同时，对于该预设第一抖动程度、该预设第二抖动程度和该预设第三抖动程度三者之间的大小关系也不做限定。
具体的，该终端根据预先记录的抖动程度，分别从该预设第一数量帧图像中确定出全部的对应该终端的抖动程度小于或等于该预设第二抖动程度的第一图像，以及从该预设第二数量帧图像中确定出全部的对应该终端的抖动程度小于或等于该预设第三抖动程度的第二图像，即从捕获的该预设第一数量帧图像和该预设第二数量帧图像中找出对应该终端的抖动程度较小时捕获的图像。
在一些可行的实施方式中，如果该预设第一数量帧图像中没有对应该终端的抖动程度小于或等于该预设第二抖动程度的图像，则此时可以考虑适当增大该预设第二抖动程度，再将该预设第一数量帧图像中每一帧图像对应该终端的抖动程度与增大后的该预设第二抖动程度进行比较，直到从该预设第一数量帧图像中找出至少1张对应该终端的抖动程度小于或等于增大后的该预设第二抖动程度的图像。同样地，如果该预设第二数量帧图像中没有对应该终端的抖动程度小于或等于该预设第三抖动程度的图像，则此时可以考虑适当增大该预设第三抖动程度，再将该预设第二数量帧图像中每一帧图像对应该终端的抖动程度与增大后的该预设第三抖动程度进行比较，直到从该预设第二数量帧图像中找出至少1张对应该终端的抖动程度小于或等于增大后的该预设第三抖动程度的图像。
208、所述终端利用预设算法对所述第一图像和所述第二图像进行合成处理，以得到拍照图像。
其中，该预设算法具体可以是线性叠加合成算法。
具体的，该终端可以利用线性叠加合成算法将该第一图像与该第二图像合成，以得到拍照图像。
本发明实施例中，终端在检测到输入的拍照指令时，利用第一摄像头捕获预设第一数量帧图像，获取记录的在利用该第一摄像头捕获该预设第一数量帧图像中的第一帧图像时该终端的抖动程度，如果大于或等于预设第一抖动程度，则该终端在经历预设时长后，利用第二摄像头捕获预设第二数量帧图像；如果小于该预设第一抖动程度，则该终端直接利用第二摄像头捕获预设第二数量帧图像，并从捕获的该预设第一数量帧图像和该预设第二数量帧图像中找出对应该终端的抖动程度较小时捕获的图像，进而利用预设算法对对应该终端的抖动程度较小时捕获的图像进行合成处理得到拍照图像，通过尽可能的在终端抖动程度较小时捕获图像，以及选取终端抖动程度较小时捕获的图像进行合成处理，可以消除拍照时图像的拖影模糊现象，提升拍照图像的质量。
