其中，所述第一显示区域可用于展示所述时钟显示界面，所述第二显示区域可用于展示所述第一图像。
需要说明的是，所述多个显示区域的相对位置可根据实际情况灵活 设置，如可设置为左右相邻、上下相邻、或者互不相邻等，本申请实施例对此不作赘述。
例如，如图2所示，假设将所述显示设备的显示屏幕划分为两个显示区域，即将所述显示设备的显示屏幕划分为第一显示区域以及第二显示区域，其中，所述第一显示区域可为所述显示设备的显示屏幕的左半部分(图2所示)、右半部分、上半部分、下半部分或者其它任意的一部分，所述第二显示区域可为所述显示设备的显示屏幕的右半部分(图2所示)、左半部分、上半部分、下半部分或者其它任意的一部分，只要能够保证所述第二显示区域中的信息不与所述第一显示区域中的信息相互遮挡即可。需要说明的是，所述第一显示区域可用于展示所述时钟显示界面，所述第二显示区域可用于展示所述第一图像，即可作为所述第一显示屏幕。当然，所述第一显示区域还可用于展示所述第一图像，所述第二显示区域还可用于展示所述时钟显示界面，本申请实施例对此不作赘述。

下面，仍以所述显示设备的显示屏幕被分为第一显示区域以及第二显示区域、且所述第一区域为所述显示设备的显示屏幕的左半部分，所述第二显示区域为所述显示设备的显示屏幕的右半部分为例，对本申请实施例中所述的当前时刻以及拍摄时刻的采集过程进行详细地介绍：
假设，所述第一显示区域用于展示某一时钟的时钟显示界面，所述第二显示区域用于展示所述第一图像，则整个采集过程可分为以下几个 步骤，如图3所示：
S31：通过待测摄像头对所述显示设备的第一显示区域进行图像获取。
如图4所示，其为本申请实施例中所述的待测摄像头与显示设备的放置示意图。具体地，由图4可知，所述待测摄像头可放置在所述显示设备的显示屏幕的第一显示区域的正前方，以使得所述待测摄像头能够完整且清晰地拍摄所述显示设备的显示屏幕的第一显示区域，例如，假设所述待测摄像头执行拍摄动作的时刻为01:12:23，则所述待测摄像头所拍摄到的所述第一图像可如图5所示。再例如，当所述时钟为指针式时钟，则所述第一图像还可如图6所示。
当然，需要说明的是，所述待测摄像头也可不完全放置在所述显示设备的显示屏幕的第一显示区域的正前方，只要能够清晰完整地拍摄到所述第一显示区域中的时钟显示界面中所呈现的时间信息即可，本申请实施例对此不作赘述。
S32：待测摄像头将拍摄到的所述第一图像传输给所述显示设备，以使得所述显示设备通过所述显示设备的显示屏幕的第二显示区域输出所述第一图像。
如图7所示，其为本申请实施例中所述的待测摄像头以及显示设备之间的信息传输示意图。具体地，以所述时钟为数字时钟为例，所述待测摄像头以及所述显示设备之间可通过有线通信方式和/或无线通信方式进行连接，其中，图7中是以有线通信方式连接的，此时，所述显示设备可通过其第二显示区域将所述待测摄像头所拍摄到的所述第一图像显示出来。其中，需要说明的是，此时，所述显示设备的第一显示区域中的时间已经发生了变化，如图7所示，可变为01:23:45，本申请实施例对此不作赘述。
S33：通过摄像单元对所述显示设备的第一显示区域以及第二显示区域进行图像获取.
如图8所示，其为本申请实施例中所述摄像单元以及显示设备的放置示意图。具体地，由图8可知，所述摄像单元可正对着所述显示设备的显示屏幕放置，以使所述摄像单元能够完整且清晰地拍摄所述显示设备的整个显示屏幕。例如，假设在所述拍摄单元执行拍摄动作时所述显示设备上显示的拍摄时刻为01:12:23、当前时刻为01:23:45，则所述摄像单元所拍摄到的所述第二图像可如图9所示。再例如，当所述时钟为指针式时钟，则所述摄像单元所拍摄到的所述第二图像还可如图10所示，本申请实施例对此不作赘述。
S34：摄像单元将拍摄到的所述第二图像发送至相应的运算处理单元。
其中，所述运算处理单元通常可包括两个子单元，如可包括提取子单元以及运算子单元。其中，所述提取子单元通常可设置在所述测试摄像头延时的装置的采集模块中，用于提取出相应的当前时刻以及拍摄时刻；所述运算子单元通常可设置在所述测试摄像头延时的装置的确定模块中，用于计算所述当前时刻以及所述拍摄时刻之间的时间差。当然，所述运算处理单元还可包括相应的显示子单元(即显示屏幕)，用于将计算得到的延时进行显示，本申请实施例对此不作赘述。
需要说明的是，所述第二图像通常可通过与所述摄像单元相对应的第二显示屏幕显示，其中，所述第二显示屏幕可独立于所述显示设备设置，也可集成在所述显示设备中。当所述第二显示屏幕为集成在所述显示设备中的集成单元时，所述显示设备的显示屏幕还可被划分成三个显示区域，如分别对应时钟、第一显示屏幕以及第二显示屏幕，本申请实施例对此不作赘述。
根据本申请一些实施例，所述摄像单元在拍摄到相应的第二图像时，也可不进行所述第二图像的显示，而是直接将所述第二图像发送至所述运算处理单元，以由所述运算处理单元通过相应的显示子单元将所述第二图像进行显示。
如图11所示，其为本申请实施例中所述的摄像单元与运算处理单元之间的信息传输示意图。具体地，所述摄像单元与所述运算处理单元之间也可通过有线通信方式和/或无线通信方式进行连接，其中，图11中是以有线通信方式连接的。
需要说明的是，如图12所示，其为本申请实施例中所述的摄像单元的第一种可能的位置示意图，所述运算处理单元还可被集成在所述显示设备中，此时，所述显示设备的显示屏幕还可被分为四个显示区域，分别对应时钟、第一显示屏幕、第二显示屏幕以及运算处理单元。其中，所述第二显示屏幕与所述运算处理单元的显示子单元还可为同一个显示区域，本申请实施例对此不作赘述。
当然，还需要说明的是，所述显示设备的多个显示区域的面积可根据实际情况灵活设置，如可设置为全部相同，也可设置为各不相同。且，不同显示区域之间可互相重叠或者不重叠，只要在需要提取相应的拍摄时刻以及当前时刻时，能够正常提取即可，本申请实施例对此不作赘述。
S35：所述运算处理单元基于图像处理，从所述第二图像中采集所述当前时刻以及所述拍摄时刻。
例如，仍以图9为例，则所述运算处理单元可基于图像处理，从图9中采集到所述拍摄时刻为01:12:23以及所述当前时刻为01:23:45。
具体地，所述图像处理通常可包括HOG(Histogram of Oriented Gradient，方向梯度直方图)技术以及SVM(Support Vector Machine，支持向量机)技术，当然，需要说明的是，所述图像处理还可包括其它 任意能够对图像中的信息进行提取的技术。
也就是说，在本申请实施例中，可基于HOG+SVM技术分析第二图像，并可从所述第二图像中提取出相应的图片信息，之后，可配合数字信息模型，计算得到所需要的拍摄时刻以及当前时刻。
由上述内容可知，除了待确定延时的待测摄像头之外，要实现本申请实施例，实际需求的设备可包括时钟、第一显示屏幕、摄像单元、第二显示屏幕以及运算处理单元，且，通常情况下，时钟、第一显示屏幕、第二显示屏幕以及运算处理单元均可集成在相应的显示设备中，因此，实际需求的设备可包括摄像单元以及相应的显示设备，这就保证了测量摄像头延时的低成本。其中，需要说明的是，所述显示设备可为具备时钟显示功能以及屏幕显示功能的手机、平板电脑、电脑等电子设备，例如，假设所述显示设备为电脑，则所述电脑中的电子钟即可为所述时钟，所述电脑的显示屏幕即可为所述第一显示屏幕和/或第二显示屏幕，所述电脑中的CPU(Central Processing Unit，中央处理器)即可为所述运算处理单元。
进一步地，由于手机、平板电脑、电脑等电子设备中通常还具备相应的截图单元或者截屏单元，因此，还可将电脑等电子设备上的截图单元或者截屏单元作为所述摄像单元，这就能够进一步减少实现本申请实施例所需要的设备，即，一台带有显示器的、具备运算能力和截图功能的电脑即可实现本申请实施例，对此不作赘述。
在本申请一些实施例中，采集所述时钟显示界面中所呈现的当前时刻以及所述第一图像中的时钟显示界面图案中所呈现的拍摄时刻，还可包括：
获取第二图像，其中，所述第二图像为对所述时钟显示界面中所呈现的当前时刻进行图像获取得到的图像；
基于图像处理，从所述第二图像中采集所述当前时刻，以及，从所述第一图像中采集所述拍摄时刻。
如图13所示，其为本申请实施例中所述的摄像单元的第二种可能的位置示意图。具体地，由图13可知，为了保证所述第二图像的清晰度，通常可将所述摄像单元放置在所述显示设备的正前方。其中，图13中所述的显示设备集成了相应的时钟、第一显示屏幕以及运算处理单元。
需要说明的是，在本申请实施例中，用以计算待测摄像头延时的数据为拍摄时刻以及当前时刻，且，由于之前已经通过所述待测摄像头得到了所述第一图像，因而，可直接通过所述运算处理单元对所述第一图像进行图像处理，即可得到相应的拍摄时刻，而无需再次对所述第一图像中的时钟显示界面图案中所呈现的拍摄时刻进行图像获取。因此，此时可仅通过所述摄像单元对所述时钟显示界面中所呈现的当前时刻进行图像获取，以使得所述运算处理单元对所述第二图像进行图像处理，以得到相应的当前时刻，从而减少了摄像单元拍摄的范围，节省了摄像单元以及相应显示设备的内部存储空间。
也就是说，在本申请实施例中，所述摄像单元除了可同时拍摄所述显示设备的显示屏幕的第一显示区域以及第二显示区域之外，还可仅拍摄所述显示设备的第一显示区域，从而能够进一步降低成本，节省资源。
在本申请一些实施例中，采集所述时钟显示界面中所呈现的当前时刻以及所述第一图像中的时钟显示界面图案中所呈现的拍摄时刻，还可包括：
从所述时钟内部的电子钟中采集所述当前时刻，以及，基于图像处理，从所述第一图像中采集所述拍摄时刻。
其中，从所述时钟内部的电子钟中采集所述当前时刻，可包括：
向所述时钟发送当前时刻获取指令，并接收所述时钟返回的所述时 钟内部的电子钟中的当前时刻；和/或，
直接访问所述时钟内部的电子钟，并获取所述电子钟中的当前时刻。
在本申请实施例中，由于之前已经通过所述待测摄像头得到了所述第一图像，因而可直接通过所述运算处理单元对所述第一图像进行图像处理，即可得到相应的拍摄时刻，而无需再次对所述第一图像中的时钟显示界面图案中所呈现的拍摄时刻进行图像获取；且，由于此时所述运算处理单元还可直接获取到所述时钟显示界面中所呈现的所述当前时刻，因而也无需采用相应的摄像单元对所述显示设备的第一显示区域进行拍摄，即无需通过相应的摄像单元对所述时钟显示界面中所呈现的当前时刻进行图像获取。
也就是说，在本申请实施例中，除了可设置相应的摄像单元来对所述时钟显示界面中所呈现的所述当前时刻进行图像获取，以得到相应的第二图像，并由所述运算处理单元基于图像处理，从所述第二图像中采集出相应的当前时刻之外，还可不设置相应的摄像单元，直接通过所述运算处理单元获取所述时钟显示界面中所呈现当前时刻，因而不仅减少了拍摄次数，节省了摄像单元以及相应显示设备的内部存储空间，还提升了摄像头延时的测试效率，降低了成本，节省了资源。
在本申请一些实施例中，根据所述当前时刻以及所述拍摄时刻，确定所述待测摄像头的延时，可包括：
计算所述当前时刻以及所述拍摄时刻之间的差值；
将所述差值作为所述待测摄像头的延时。
仍以上述例子为例，假设所述运算处理单元采集到的所述拍摄时刻为01:12:23、所述当前时刻为01:23:45，则可得到所述待测摄像头的延时为11分22秒。
需要说明的是，由于在本申请实施例中，可利用显示设备的读取功 能实现所述拍摄时刻以及所述当前时刻的读取，并可利用所述显示设备的计算功能实现所述待测摄像头的延时的确定，因而不会存在由于视觉误差以及反应误差所导致的准确性较低以及效率较低的问题；且，由于整个过程不需要依靠任何人力，因此还能降低摄像头延时的确定成本，节省人力资源。
另外，本申请实施例中，在计算得到相应的延时之后，还可将所述延时按照设定的要求进行显示，例如，可将所述延时通过所述运算处理单元的显示屏幕进行显示等，或者，可将所述延时通过所述显示设备的显示屏幕进行显示等。当然，需要说明的是，还可将所述延时通过相应的语音播放单元播放出来，其中，所述语音播放单元可独立设置在所述显示设备之外，且可与所述运算处理单元进行连接，连接的方式可包括有线通信方式和/或无线通信方式；在本申请另外一些实施例中，所述语音播放单元，还可被集成在所述显示设备中，对此不作赘述。
在本申请一些实施例中，在确定了所述待测摄像头的延时之后，还可基于所述延时，确定所述待测摄像头的延时随着时间的变化趋势，如图14所示，其为本申请实施例中所述的待测摄像头的延时与时间的关系示意图。在图14中，纵坐标Delay表示延时，横坐标Time表示时间，横坐标上的每个点代表一个小时。具体地，由图14可知，随着时间的不断增加，所述待测摄像头的延时逐渐变大，因而就能够为用户挑选摄像头提供相应的参考和依据。例如，用户在购买相机时，如果发现该相机的摄像头延时随着使用时间的增加发生了大幅度地增加，则该用户可确定该相机的性能并不佳；反之，如果发现该相机的摄像头延时随着使用时间的增加发生了较小幅度地增加，则该用户可确定该相机的性能较好，本申请实施例对此不作赘述。
本申请实施例一提供了一种测试摄像头延时的方法，可获取时钟显 示界面的第一图像，其中，所述第一图像为利用待测摄像头对所述时钟显示界面进行图像获取得到的图像；并可在所述待测摄像头输出所述第一图像时，采集所述时钟显示界面中所呈现的当前时刻，以及从所述第一图像中采集时钟显示界面图案中所呈现的时刻并将该时刻确定为拍摄时刻；之后，可根据所述当前时刻以及所述拍摄时刻，确定所述待测摄像头的延时。在本申请实施例中，无需人工确定进行拍摄的拍摄时刻以及待测摄像头输出所拍摄到的图像的当前时刻，也无需人工按压相应的秒表，更无需人工计算当前时刻与拍摄时刻之间的时间差，因而不会存在由于人的视觉误差以及反应误差所带来的准确性较低以及效率较低的问题；且，在本申请实施例中，由于无需使用较多的人力资源即可实现摄像头延时的精确确定，因而还能减少资源的浪费，降低延时确定的成本。解决了现有的测试摄像头延时的方法所存在的准确性较低、效率较低以及资源浪费较严重的问题。

  15. 如权利要求13所述的非易失性计算机可读存储介质，所述采集所述时钟显示界面中所呈现的当前时刻，以及从所述第一图像中采集时钟显示界面图案中所呈现的时刻并将该时刻确定为拍摄时刻，包括：
    获取第二图像，其中，所述第二图像为对所述时钟显示界面中所呈现的当前时刻进行图像获取得到的图像；
    基于图像处理，从所述第二图像中采集所述当前时刻，以及，从所述第一图像中采集所述拍摄时刻。
  16. 如权利要求13所述的非易失性计算机可读存储介质，所述采 集所述时钟显示界面中所呈现的当前时刻，以及从所述第一图像中采集时钟显示界面图案中所呈现的时刻并将该时刻确定为拍摄时刻，包括：
    从所述时钟内部的电子钟中采集所述当前时刻，以及，基于图像处理，从所述第一图像中采集所述拍摄时刻。
  17. 如权利要求13所述的非易失性计算机可读存储介质，所述根据所述当前时刻以及所述拍摄时刻，确定所述待测摄像头的延时，包括：
    计算所述当前时刻以及所述拍摄时刻之间的差值；
    将所述差值作为所述待测摄像头的延时。
  18. 如权利要求13～17任一项所述的非易失性计算机可读存储介质，所述机器可读指令可以由处理器执行以完成以下操作：
    在获取时钟显示界面的第一图像之前，将显示设备的显示屏幕划分为多个显示区域，所述多个显示区域包括第一显示区域以及第二显示区域；
    其中，所述第一显示区域用于展示所述时钟显示界面，所述第二显示区域用于展示所述第一图像。
