背景技术
当本地用户终端与远程用户终端进行视频会议时，通常由本地用户终端通过控制摄像头对采集的视频内容进行调整，当远程用户终端需要对摄像头采集的视频图像内容的某些细节进行详细查看时，往往需要远程用户终端指示本地用户终端对摄像头进行调整。
在相关技术中，通常由远程用户通过远端摄像机控制协议(Far End Cameral Control，FECC)将对本地用户终端摄像头进行调整的调整信息发送到本地用户终端中，本地用户终端根据上述调整信息对摄像头进行调整，但是上述调整过程需要远程用户终端与本地用户终端进行多次交互，导致本地用户终端反复调整摄像头才能得到期望显示的视频图像内容，使得视频图像内容的调整过慢，交互频繁且调整准确度不高，用户体验较差。

本实施例提供了一种运行于上述网络架构的图像采集的处理方法，图2是本实施例提供的图像采集的处理方法的流程示意图(一)，如图2所示，该流程可以包括步骤202-步骤204。
在步骤202中，第一终端接收第二终端发送的位置信息。
其中，位置信息用于指示第二终端的显示图像的图像区域，图像区域为对第二终端的显示图像进行区域划分后得到的区域；
对第二终端的显示图像进行划分后得到的图像区域也可以称作图像子区域，上述第一终端和第二终端可以为视频会议中两台相同的终端设备，但这两台终端设备设置在不同的使用侧。位置信息可以理解为摄像头能够支持的调整范围和幅度，可以包括角度和焦距信息等，可以将摄像头覆盖的图像区域划分 成多个图像子区域，每个图像子区域都有对应的位置信息。
在步骤204中，第一终端依据位置信息调整第一终端本地的图像采集装置的图像采集参数。
其中，图像采集装置设置为在第一终端侧采集所述第二终端所显示的图像。在步骤202中，对于显示图像的区域划分可以是将上述显示图像预先进行划分，或者实时对上述显示图像进行划分；例如，对于上述显示图像按照面积的大小进行均分，或者按照一定的算法实时对上述显示图像进行区域划分，例如，对第二终端侧实时显示的视频图像进行区域划分。
其中，上述对显示图像进行区域划分的算法可以为将显示图像划分为N*M个图像子区域，N表示将图像的横向划分为N份，M表示将图像的纵向划分为M份，可以根据不同使用场景中关注的信息不同，来设定N和M的值。例如，可以采用均分的方法，将显示图像划分为2*2或3*3个图像子区域，也可以采用不均分的方法，将显示图像划分为1*3或3*1个图像子区域，并且多个图像子区域的面积可以相同也可以不同。
可选地，在步骤204中，第一终端本地的图像采集装置可以为摄像机，其中，该图像采集装置与第一终端位于同一侧，例如，视频会议中图像采集终端和摄像机位于同一侧，此外，该图像采集装置可以是设置在第一终端中的图像采集装置(例如终端中的摄像头)，也可以是独立于第一终端之外的图像采集装置，当上述图像采集装置为独立的图像采集装置时，该图像采集装置与第一终端相连接。

可选地，串口控制字中携带有位置信息和图像采集装置的焦距中的至少一种信息。在本实施例中，可以将第二终端的显示图像的图像区域进行划分，并为每个区域设置相应的控制字。

在步骤504中，终端B收到可以选择的图像区域信息后，用户可以根据需要查看的图像区域细节，选择所要放大的图像区域，终端B确定所要放大的图像区域对应的位置信息，并将该位置信息通过FECC通道发送给终端A；
在步骤506中，终端A收到终端B发送的位置信息后，查找N*M个图像区域与串口控制字的对应表，得到终端B需要查看的图像区域细节对应的串口控制字；
在步骤508中，将需要查看的图像区域细节对应的串口控制字通过串口协议写入摄像头；
在步骤510中，摄像头根据串口控制字中携带的位置信息和焦距信息调整摄像头的角度和焦距，使摄像头对准用户选择的要放大的图像区域，并采集相应的视频图像信息，提供给所述第二终端B进行展示。
例如，摄像头根据串口控制字中的位置信息调整摄像头在上、下、左和右四个方向中的至少一个方向上的旋转角度，并根据串口控制字中的焦距信息，调整摄像头的焦距，以确保在第二终端侧清楚地展示用户需要查看的图像区域细节视频图像。
