具体实施方式
下面将参照附图更详细地描述本公开的示例性实施例。虽然附图中显示了本公开的示例性实施例，然而应当理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了能够更透彻地理解本公开，并且能够将本公开的范围完整的传达给本领域的技术人员。
本公开实施例提供一种拍照方法及移动终端，以解决现有技术中移动终端装置前后摄像头或者多摄像头满足用户的拍摄需求，而导致占用移动终端过多装置空间的问题。
本公开实施例应用于包括可折叠屏幕的移动终端，所述可折叠屏幕设有第一摄像头和第二摄像头。
参照图1，示出了本公开的一些实施例的一种拍照方法的流程图，具体可以包括如下步骤110和120。
步骤110，检测到预设折叠操作，将所述可折叠屏幕划分为第一显示屏和第二显示屏，其中，所述第一摄像头设于第一显示屏和第二摄像头设于所述第二显示屏，且所述第一摄像头和第二摄像头在可折叠屏幕未折叠时位于双摄的预设距离之内。
本公开实施例中，对于配置折叠屏幕的移动终端，当检测到可折叠屏幕的折叠操作时，在电子设备的可折叠屏幕处于弯折状态时，以折叠屏幕的折叠线为基准，将可折叠平屏幕划分为两个屏幕，分别为第一屏幕和第二屏幕，其中，第一摄像头位于第一屏幕和第二摄像头位于第二屏幕上，所以通常情况下折叠屏幕上的折叠线通常位于设置的两个摄像头之间。
在实际应用中，折叠屏幕上可以设置至少两个摄像头，折叠线位于这两个摄像头之间，如果设置的摄像头多于两个，则保证折叠线所处位置可以将摄像头分开设置在第一屏幕和第二屏幕上，并且两个摄像头在可折叠屏幕未折叠时位于双摄的预设距离之内，具体设置距离根据不同的移动终端设置参数而不同，对此本公开实施例不加以限制。
步骤120，若检测到所述拍摄应用启动，则所述第二显示屏显示所述第 一摄像头的取景画面，所述第一显示屏显示所述第二摄像头的取景画面。
本公开实施例中，进一步的监测当前移动终端上的拍摄应用是否启动，其中，以安卓系统为例，应用的activity是否显示在界面是决定应用是打开还是关闭的核心因素。一个应用只有一个activity并且不支持横屏，这个activity的onstart和onstop方法就决定了这个应用是打开的还是关闭的，所以查看函数onstart()和onstop()的返回值即可明确得知一应用的启动状态。具体的，当使用上述描述的方法监测到拍摄应用时启动状态，那么根据在拍摄应用中的预设参数，在折叠状态下第一屏幕上配置的第一摄像头为第二屏幕的后置摄像头，而同样的，第二屏幕上配置的第二摄像头为第一屏幕的后置摄像头，并在第二显示屏显示第一摄像头的取景画面，在第一显示屏显示第二摄像头的取景画面。
在本公开实施例中，当可折叠屏幕未折叠时，第一摄像头和第二摄像头之间的距离在可实现双摄的预设距离之内，当折叠时，第一摄像头和第二摄像头分别用作前置摄像头和后置摄像头使用，实现了在移动终端上配置两个可实现双摄的前置摄像头，并通过折叠操作而实现前后置摄像头功能。
参照图2，示出了本公开的另一些实施例的一种拍照方法的流程图，具体可以包括如下步骤201至205。
步骤201，获取可折叠屏中折叠感应器在预设方向上的折叠感应数据，计算所述可折叠屏的折叠角度。
本公开实施例中，通常在折叠屏的折叠线处会配置有折叠感应器，可以感应折叠屏幕折叠的方向和角度，当感应器检测到折叠操作时，通过两个屏幕上分别装置的折叠感应元件获取的数据，进一步的判断折叠屏幕的折叠方向以及折叠角度。
步骤202，若所述折叠角度超过预设阈值，则将所述可折叠屏划分为第一显示屏和第二显示屏。
本公开实施例中，当通过感应元件获取第一显示屏和第二显示屏的相对折叠方向时，进一步的获取在第一显示屏和第二显示屏预置感应点的相对距离，然后根据上述相对距离以及感应点相对于折叠线的距离，进一步的可以计算出第一显示屏和第二显示屏是之间的折叠角度。例如，图2A描述的折 叠屏幕侧面示意图中，A为第一显示屏上的预置感应点，B为第二显示屏上的预置感应点，通过设置在两个显示屏上的感应元件可以测出A点与B点之间的相对距离AB，还可以计算出A点距离折叠线C点的距离AC，也可以得知B点距离折叠线C点的距离BC，当得知AB、AC、BC的值后可以通过三角形余弦定理计算出角C的值，那么第一显示屏和第二显示屏之间的折叠角度为180度与角C的值获得的差值。预设阈值可以设为120°至180°之间任一值。
实际应用中，若检测出距离AB的值为0，那么进一步的可以计算出角C的值为0，则第一显示屏和第二显示屏之间的折叠角度为180°，此时则可以确定第一显示屏与第二显示屏进行了折叠连接，它们之间的背面完全叠合。
当然在实际应用中，预设可折叠操作确定的预设角度并不一定是180°，可以是用户设置或相关技术人员设置的可折叠角度，本公开实施例对此不加以限制。
步骤203，若检测到所述拍摄应用启动，则所述第二显示屏显示所述第一摄像头的取景画面，所述第一显示屏显示所述第二摄像头的取景画面。
本公开实施例中，当检测到拍摄应用为启动状态时，此时在第一显示屏上的显示内容根据预设的显示为第二摄像头捕捉的画面，在第二显示屏上显示的是第一摄像头拍摄的画面。
在实际应用中，预设的第一显示屏和第二显示屏上的显示画面可以根据用户的需求进行改变，例如可以在摄像头每次启用时，都在第一显示屏上显示第二摄像头拍摄画面，在第二显示屏显示第一摄像头拍摄画面。当然，也可以显示上次拍摄应用关闭时的取景画面，具体根据用户需求设置，本公开实施例对此不加以限制。
步骤204，若检测到所述拍摄应用的关闭操作，则记录所述第一显示屏和所述第二显示屏的显示参数；所述显示参数包括：第一显示屏和第二显示屏与第一摄像头和第二摄像头的对应关系。
本公开实施例中，当检测到拍摄应用为关闭状态时，则记录折叠双屏中的取景画面对应的摄像头的参数。例如，在拍摄应用关闭时，第一显示屏中显示画面是由第二摄像头拍摄的，第一显示屏的显示画面是由第一摄像头拍 摄的，那么就记录该对应关系，以及各摄像头取景参数，聚焦、特效选择等，对于显示参数具体包含除显示屏与摄像头的对应关系以外，具体包括的取景参数可以根据用户需求进行设定，本公开实施例不加以限制。
步骤205，若检测到所述拍摄应用的再次开启操作，根据所述显示参数，在所述第一显示屏和所述第二显示屏中显示由对应摄像头拍摄的画面。
本公开实施例中，当检测到拍摄应用开启时，如果监测到第一显示屏和第二显示屏的摄像头的显示参数，那么就根据摄像头的显示参数中记录的显示屏与摄像头的对应关系，以及摄像头的取景参数，分别在第一显示屏和第二显示屏中显示对应摄像头的取景画面。
可选地，在本公开另一些实施例中，所述拍照方法还包括步骤203A-203C和206-210。
步骤203A，分别通过第一摄像头和第二摄像头采集人脸信息；
本公开实施例中，对于手机拍照时人脸识别主要应用：拍摄场景中人脸检测与定位，而基于几何特征的人脸检测方法中，首先确定人脸由眼睛、鼻子、嘴巴、下巴等部件构成，正因为这些部件的形状、大小和结构上的各种差异才使得世界上每个人脸千差万别，因此对这些部件的形状和结构关系的几何描述可以作为人脸识别的重要特征。大致的，首先根据轮廓曲线确定若干显著点，并由这些显著点导出一组用于识别的特征度量如距离、角度、等由正面灰度图中线附近的积分投影。当拍照过程中发现符合识别特征的轮廓曲线，就能快速定位和标记出来，以便快速识别拍摄画面中的人脸特征。
步骤203B，获取第一摄像头和第二摄像头中未采集到人脸信息的目标摄像头；
本公开实施例中，若通过人脸特征采集技术未能在第一摄像头或第二摄像头的拍摄画面中提取人脸特征信息，则确定该摄像头未采集到人脸信息，以下以第二摄像头未采集到人脸信息为例进一步说明。
步骤203C，关闭所述目标摄像头对应的显示屏。
本公开实施例中，将未采集到人脸特征信息的摄像头进行关闭，以节省移动终端的电量消耗。由于第二摄像头未采集到人脸信息，说明用户不在第二摄像头一侧，由于第二摄像头对应的是第二显示屏，故关闭第二显示屏， 仅保留第一显示进行显示并不会影响到用户的使用。
步骤206，若接收到在所述第一显示屏上的摄像头转换操作，且所述第一显示屏中的取景画面由所述第一摄像头拍摄，则在所述第一显示屏上显示所述第二摄像头拍摄的画面。
本公开实施例中，当检测到第一显示屏上显示的画面是第二摄像头拍摄的，而此时，如果第二显示屏中展示的画面也是有第二摄像头拍摄的，那么就立即转换，在第二显示屏上展示第一摄像头拍摄的画面。以安卓系统为例，在Camera中都存在摄像头切换指令，在判断屏幕上当前取景画面是由哪个摄像头拍摄的，可以调用CameraInfo类，利用其中的BACK_FACING_CAMERA和FRONT_FACING_CAMERA，可以判定第一显示屏和第二显示屏上分别展示的是第一摄像头或第二摄像头拍摄的画面，如果两个显示屏上展示相同摄像头拍摄画面，那么就按照预设用户习惯，将其中一个显示屏中展示的画面进行切换。
实际应用中，当用户在第一显示屏上进行了摄像头切换操作，那么根据设置，如果第一显示屏上展示的内容是由第一摄像头拍摄的，则将取景画面切换为第二摄像头拍摄的画面。当然，若此时第二显示屏上展示的是由第二摄像头拍摄的画面，则同时切换为由第一摄像头拍摄的画面。
步骤207，若接收到在所述第一显示屏上的摄像头转换操作，且所述第一显示屏中的取景画面由所述第二摄像头拍摄，则在所述第一显示屏上显示所述第一摄像头拍摄的画面。
本公开实施例中，当用户在第一显示屏上进行了摄像头切换操作，那么根据设置，如果第一显示屏上展示的内容是由第二摄像头拍摄的，则将取景画面切换为第一摄像头拍摄的画面。当然，若此时第二显示屏上展示的是由第一摄像头拍摄的画面，则同时切换为由第二摄像头拍摄的画面。
步骤208，若接收到在所述第二显示屏上的摄像头转换操作，且所述第二显示屏中的取景画面由所述第二摄像头拍摄，则在所述第二显示屏上显示所述第一摄像头拍摄的画面。
本公开实施例中，当用户在第二显示屏上进行了摄像头切换操作，那么根据设置，如果第二显示屏上展示的内容是由第二摄像头拍摄的，则将取景 画面切换为第一摄像头拍摄的画面。当然，若此时第一显示屏上展示的是由第一摄像头拍摄的画面，则同时切换为由第二摄像头拍摄的画面。
步骤209，若接收到在所述第二显示屏上的摄像头转换操作，且所述第二显示屏中的取景画面由所述第一摄像头拍摄，则在所述第二显示屏上显示所述第二摄像头拍摄的画面。
本公开实施例中，当用户在第二显示屏上进行了摄像头切换操作，那么根据设置，如果第一显示屏上展示的内容是由第一摄像头拍摄的，则将取景画面切换为第二摄像头拍摄的画面。当然，若此时第二显示屏上展示的是由第二摄像头拍摄的画面，则同时切换为由第一摄像头拍摄的画面。
在实际应用中，在接收到切换操作后，也可以允许两个显示屏上展示的是有一个摄像头拍摄的画面，并不将另一个显示屏展示的画面进行切换，本公开实施例对此不加以限制。
步骤210，检测在任一所述显示屏上的拍摄操作，同时获取所述第一显示屏和所述第二显示屏上的取景画面对应的图像，并分别存储至预设存储目录下。
本公开实施例中，如果用户在第一显示屏或第二显示屏上点击拍摄按钮，或者按压移动终端任一设置为快捷拍摄的物理按键，例如，在拍摄应用启动时，音量键可以设置为快捷拍摄的按键，所以，当检测到用户点击任一预设的拍摄按键后，同时拍摄第一显示屏和第二任显示屏上展示的画面，并分别存储在目录。当然，在实际应用中，也可以将两个显示屏上展示的画面合并为一张图片进行存储，用户可以在拍摄应用的设置中对其进行修改，本公开实施例对此不加以限制。
在本公开实施例中，通过在移动终端上可折叠屏幕的折叠操作，将对应屏幕分为第一屏幕和第二屏幕，在检测到两个屏幕折叠时，且拍摄应用开启时，分别配置在两个屏幕上的摄像头为第一摄像头和第二摄像头，并且在一个显示屏上切换摄像头时，另一个屏幕也进行切换摄像头，并展示切换后摄像头的拍摄画面，以此实现了在移动终端上通过折叠屏幕的折叠操作实现前后置摄像头功能。

在本申请所提供的实施例中，应该理解到，所揭露的装置和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另一点，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口，装置或单元的间接耦合或通信连接，可以是电性，机械或其它的形式。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本实施例方案的目的。
另外，在本公开各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以两个或两个以上单元集成在一个单元中。
