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。
本发明实施例提供一种电子设备，该电子设备为可折叠的电子设备，如图2至图4所示，电子设备可以包括第一组件210和第二组件220，第二组件220可相对于第一组件210折叠，第一组件210的第一表面211设置有第一摄像头模组212，用于拍摄第一表面211所面向的物体；第二组件220的第二表面221设置有第二摄像头模组222，用于拍摄第二表面221所面向的物体；
如图2和图4所示，在电子设备处于展开状态，且第一组件210和第二组件220平齐设置的情况下，第一表面211和第二表面221共同形成电子设备的一个平面。这里，第一表面211、第二表面221以及第一表面211和第二表面221的连接面，可以共同形成电子设备的一个显示屏；或者，如图4所示，第三表面(图中未标注)、第四表面(图中未标注)以及第三表面和第四 表面的连接面，可以共同形成电子设备的一个显示屏，其中，第三表面为第一组件210上与第一表面211相对应的表面，第四表面为第二组件220上与第二表面221相对的表面。本发明实施例中，对于第一摄像头模组212在第一组件210的第一表面211上的具体设置位置以及第二摄像头模组222在第二组件220的第二表面221上的具体设置位置可以结合根据电子设备的实际设计需求进行设置，这里不作具体限定。另外，可以理解的是，对于第一摄像头模组212和第二摄像头模组222而言，根据实际设计需求，每一摄像头模组中均可以包括至少一个摄像头。其中，第一摄像头模组212和第二摄像头模组222可以采用不同类型的摄像头构成，以此实现超广角拍摄，或大角度、双维度等不同类型的全景拍摄。
该电子设备还可以包括角度检测装置和处理器。
角度检测装置用于检测第一表面211与第二表面221的折叠角度；处理器与目标摄像头模组和角度检测装置分别连接，用于根据折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，目标摄像头模组为第一摄像头模组212和第二摄像头模组222中的至少一个，目标摄像头模组能够绕一支点中心轴相对于其所在表面转动，支点中心轴241与第一组件210和第二组件220之间的折叠中心轴平行；可以理解地，若目标摄像头模组为第一摄像头模组212，目标摄像头模组所在表面为第一表面211，则目标摄像头模组与其所在表面之间的相对角度为第一摄像头模组212与第一表面211之间的相对角度；若目标摄像头模组为第二摄像头模组222，目标摄像头模组所在表面为第二表面221，则目标摄像头模组与其所在表面之间的相对角度为第二摄像头模组222与第二表面221之间的相对角度。
在相对角度调节完成的情况下，第一摄像头模组212和第二摄像头模组222的焦平面间的夹角小于预设角度。也就是说，第一摄像头模组212和第二摄像头模组222的物平面(或光轴或拍摄平面)间的夹角小于预设角度。
本发明实施例中，处理器获取角度检测装置检测的折叠角度，然后根据折叠角度，向目标摄像头模组输出指令信号，以调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组212和第二摄像头模组222的焦平面间的夹角小于预设角度，以满足第一摄像头模组212和第二摄像头模组 222共同拍摄的角度要求。其中，处理器还可以输出拍摄信号给第一摄像头模组212和第二摄像头模组222，以控制第一摄像头模组212和第二摄像头模组222启动并进行拍摄。
本发明实施例中，通过角度检测装置检测第一表面211与第二表面221的折叠角度，处理器根据折叠角度调节目标摄像头模组与其所在表面之间的相对角度，在相对角度调节完成的情况下，第一摄像头模组212和第二摄像头模组222的焦平面间的夹角小于预设角度，从而能够满足第一摄像头模组212和第二摄像头模组222共同拍摄的角度要求，保证多摄像头拍摄效果。
较优地，在本发明实施例中，为确保第一摄像头模组212和第二摄像头模组222具备更佳的共同拍摄效果，可以取预设角度为0，也就是说，在相对角度调节完成的情况下，第一摄像头模组212和第二摄像头模组222的焦平面平行或处于同一平面。
可选地，在本发明一些实施例中，如图3和图4所示，电子设备还可以包括：折叠机构250。折叠机构250连接于第一组件210和第二组件220之间，角度检测装置设置于折叠机构250内部。这里，第一组件210与第二组件220之间可以通过一折叠机构250连接，并通过折叠机构内部设置的角度检测装置即可便捷地确定第一表面211和第二表面221之间的折叠角度。示例地，该角度检测装置可以为角度传感器。或者，示例地，该角度检测装置也可以为应变片，这样，可以通过折叠机构折叠过程中应变片的电阻变化引起的电压信号或电流信号变化，检测确定第一表面211与第二表面221的折叠角度。
当然，在具体使用中，该角度检测装置也可以设置于电子设备中内部，以利于折叠机构的结构设置以及电子设备外观舒适性。示例地，该角度检测装置可以为例如重力传感器、陀螺仪等重力传感设备，这样，角度检测装置可以通过检测第一组件210的第一表面211的第一空间方位以及第二组件220的第二表面221的第二空间方位，并基于第一空间方位和第二空间方位确定第一表面211和第二表面221的折叠角度。可以理解地，在一些实施例中，第一组件210与第二组件220可以是不相邻接的两个组件，即第一组件210与第二组件220之间可以间隔至少一个组件设置，此时，可以通过重力传感 设备检测第一表面211和第二表面221的折叠角度。
可选地，在本发明一些实施例中，如图5所示(图5中以目标摄像头包括第二摄像头模组222作为示例)，目标摄像头模组上设置有角度调节结构231，该目标摄像头模组通过角度调节结构231带动转动，也即目标摄像头模组可通过角度调节结构231沿支点中心轴241相对于其所在表面转动。其中，处理器与角度调节结构231连接，这里，处理器可以根据折叠角度，确定满足第一摄像头模组212和第二摄像头模组222的焦平面间的夹角小于预设角度的情况下目标摄像头模组的所需调整角度，然后根据该所需调整角度确定角度调节结构231的驱动参数，并向角度调节结构231发送该驱动参数，角度调节结构231根据该驱动参数驱动目标摄像头模组转动，这样，在目标摄像头模组转动完成后，第一摄像头模组212和第二摄像头模组222的焦平面间的夹角小于预设角度，从而能够满足第一摄像头模组212和第二摄像头模组222共同拍摄的角度要求，保证多摄像头拍摄效果。
本发明实施例中，支点中心轴241可以设置于目标摄像头模组上与角度调节结构231相对的一侧，如图5所示，该角度调节结构231和支点中心轴241分别设置于目标摄像头模组的两端；或者，也可以设置于目标摄像头的底部。
本发明实施例中，在具体使用过程中，考虑到目标摄像头模组与其所在表面之间可以发生过偏转，例如目标摄像头模组在第二组件和第一组件本次折叠之前已经发生过角度调节的情形，此时，为了更好地确保第一摄像头模组212和第二摄像头模组222共同拍摄的角度要求，处理器可以获取确定目标摄像头模组的焦平面与目标摄像头模组所在表面之间的第一夹角，示例地，处理器可以通过接收角度调节结构231输出的信号确定该第一夹角；处理器可以根据第一夹角以及角度检测装置检测的第一表面211和第二表面221的折叠角度，调节目标摄像头模组与其所在表面之间的相对角度。
另外，该电子设备还可以包括主板、电池、麦克风、扬声器、天线以及至少一种传感器等，该至少一种传感器可以包括但不限于例如光传感器、运动传感器、指纹传感器、压力传感器、虹膜传感器、分子传感器以及陀螺仪等中的一种或多种。
本发明实施例中，该终端可以为手机或平板电脑。可以理解的是，该终端并不局限于手机和平板电脑，其也可以为膝上型电脑(Laptop Computer)或个人数字助理(Personal Digital Assistant，PDA)等电子设备。
本发明实施例提供的电子设备，通过角度检测装置检测第一表面与第二表面的折叠角度，处理器根据折叠角度调节目标摄像头模组与其所在表面之间的相对角度，在相对角度调节完成的情况下，第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，从而能够满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求，保证多摄像头拍摄效果。
请参见图1，其示出的是本发明实施例提供的拍摄方法的流程框图，本发明实施例提供一种拍摄方法，应用于上述的电子设备，该拍摄方法可以包括以下步骤：
步骤101，在电子设备处于展开状态，且接收到第一摄像头模组和第二摄像头模组的启动输入的情况下，获取第一表面与第二表面的折叠角度。
本发明实施例中，在用户展开电子设备并执行启动第一摄像头和第二摄像头的启动输入时，电子设备检测到电子设备处于展开状态且接收到启动输入，对第一表面和第二表面的折叠角度进行检测获取，以便于后续步骤基于折叠角度对目标摄像头模组与其所在表面之间的相对角度进行调节，以使第一摄像头模组和第二摄像头模组满足共同拍摄时的角度要求。
步骤102，根据折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度。
这里，目标摄像头模组为第一摄像头模组和第二摄像头模组中的至少一个，目标摄像头模组能够沿支点中心轴相对于其所在表面转动，支点中心轴与第一组件和第二组件的折叠中心轴平行。本发明实施例中，预先可以设置折叠角度与相对角度之间的对应关系，这样，即可基于折叠角度，确定与折叠角度相对应的相对角度，并对目标摄像头模组进行调节，以使第一摄像头模组的焦平面和第二摄像头模组的焦平面间的夹角小于预设角度，从而满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求。
步骤103，在相对角度调节完成后，控制第一摄像头模组和第二摄像头 模组进行拍摄。
本发明实施例中，电子设备在步骤102对目标摄像头模组与其所在表面之间的相对角度调节完成后，第一摄像头模组的焦平面和第二摄像头模组的焦平面间的夹角小于预设角度，可以理解地，第一摄像头模组和第二摄像头模组的物平面(或光轴或拍摄平面)间的夹角小于预设角度，此时，即可控制第一摄像头模组和第二摄像头模组执行共同拍摄操作，从而实现第一摄像头模组和第二摄像头模组构成的多摄像头拍摄。
本发明实施例中，通过根据第一表面与第二表面的折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，然后在相对角度调节完成后，控制第一摄像头模组和第二摄像头模组进行拍摄，能够满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求，保证多摄像头拍摄效果，提升用户拍摄体验。
可选地，在本发明一些实施例中，第一组件与第二组件可以为相邻接的两个组件，此时，可以通过连接两个组件的折叠机构来获取第一表面和第二表面的折叠角度。举例来说，步骤101，在电子设备处于展开状态，且接收到第一摄像头模组和第二摄像头模组的启动输入的情况下，获取第一表面和第二表面的折叠角度，可以包括以下步骤：在电子设备处于展开状态，且接收到第一摄像头模组和第二摄像头模组的启动输入的情况下，获取第一组件与第二组件之间连接的折叠机构的转动角度；根据转动角度，确定第一表面和第二表面的折叠角度。这样，通过获取折叠机构的转动角度即可便捷地确定第一表面和第二表面的折叠角度。
可选地，在本发明一些实施例中，第一组件与第二组件也可以是不相邻接的两个组件，即第一组件与第二组件之间可以间隔至少一个组件设置，此时，可以通过重力传感器、陀螺仪等重力传感设备检测第一组件的第一表面的第一空间方位以及第二组件的第二表面的第二空间方位，并基于第一空间方位和第二空间方位确定第一表面和第二表面的折叠角度。
可选地，在本发明一些实施例中，考虑到目标摄像头模组与其所在表面之间可以发生过偏转，为了更好地确保第一摄像头模组和第二摄像头模组共 同拍摄的角度要求，步骤102，根据折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，可以包括以下步骤：确定目标摄像头模组的焦平面与目标摄像头模组所在表面之间的第一夹角；根据第一夹角和折叠角度，调节目标摄像头模组与其所在表面之间的相对角度。
举例来说，本发明实施例中，目标摄像头模组包括第一摄像头模组和第二摄像头模组，考虑到用户在拍摄过程中，通常居中握持电子设备来进行拍摄，这里，可以将与第一组件和第二组件的折叠平分线垂直的屏幕作为参考平面，记作平面Z，这样，根据第一夹角和折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，可以包括以下步骤：以目标摄像头模组垂直于目标摄像头模组所在表面时的光轴作为参考线，在目标摄像头模组的光轴相对于参考线朝向第一方位偏转的情况下，按照以下公式：a＝b+(折叠角度-π)/2，确定目标摄像头模组相对于其所在表面所需调节的目标角度，并按照目标角度调节目标摄像头模组与其所在表面之间的相对角度；在目标摄像头模组的光轴相对于参考线朝向第二方位偏转的情况下，按照以下公式：a＝b-(折叠角度-π)/2，确定目标摄像头模组相对于其所在表面所需调节的目标角度，并按照目标角度调节目标摄像头模组与其所在表面之间的相对角度。其中，a为目标角度，b为第一夹角。第一方位为目标摄像头模组的光轴相对于参考线、朝向远离与目标摄像头模组所在组件相对折叠的另一组件的方位，第二方位为目标摄像头模组的光轴相对于参考线、朝向靠近与目标摄像头模组所在组件相对折叠的另一组件的方位，也即，若目标摄像头模组为第一摄像头模组，第一方位为第一摄像头模组的光轴相对于参考线朝向远离第二组件的方位，第二方位为第一摄像头模组的光轴相对于参考线朝向靠近第二组件的方位；若目标摄像头模组为第二摄像头模组，第一方位为第二摄像头模组的光轴相对于参考线朝向远离第一组件的方位，第二方位为第二摄像头模组的光轴相对于参考线朝向靠近第一组件的方位。
示例地，如图6a所示，平面Z为参考平面，x1为第一摄像头模组212的光轴，y1为第一摄像头模组212垂直于第一表面211时的光轴，也即参考线；在第一摄像头模组212的光轴x1相对于参考线y1朝向第一方位偏转的 情况下，第一摄像头模组212相对于第一表面211所需调节的第一目标角度a1可以根据角度C以及第一摄像头模组212的焦平面与第一表面211之间的第一夹角b1确定，即a1＝b1+C/2，这里，C＝第一表面211与第二表面221的折叠角度-π，也即可以按照以下公式：a1＝b1+(折叠角度-π)/2，确定第一摄像头模组212相对于第一表面211所需调节的第一目标角度a1，并按照第一目标角度a1调节第一摄像头模组212与第一表面211之间的相对角度。同理，x2为第二摄像头模组222的光轴，y2为第二摄像头模组222垂直于第二表面221时的光轴，也即参考线；在第二摄像头模组222的光轴x2相对于参考线y2朝向第一方位偏转的情况下，第二摄像头模组222相对于第二表面221所需调节的第二目标角度a2可以根据角度C以及第二摄像头模组222的焦平面与第二表面221之间的第一夹角b2确定，即a2＝b2+C/2，这里，C＝第一表面211与第二表面221的折叠角度-π，也即可以按照以下公式：a2＝b2+(折叠角度-π)/2，确定第二摄像头模组222相对于第二表面221所需调节的第二目标角度a2，并按照第二目标角度a2调节第二摄像头模组222与第二表面221之间的相对角度。
示例地，如图6b所示，平面Z为参考平面，x1为第一摄像头模组212的光轴，y1为第一摄像头模组212垂直于第一表面211时的光轴，也即参考线；在第一摄像头模组212的光轴x1相对于参考线y1朝向第二方位偏转的情况下，第一摄像头模组212相对于第一表面211所需调节的第一目标角度a1可以根据角度C以及第一摄像头模组212的焦平面与第一表面211之间的第一夹角b1确定，即a1＝b1-C/2，这里，C＝第一表面211与第二表面221的折叠角度-π，也即可以按照以下公式：a1＝b1-(折叠角度-π)/2，确定第一摄像头模组212相对于第一表面211所需调节的第一目标角度a1，并按照第一目标角度a1调节第一摄像头模组212与第一表面211之间的相对角度。同理，x2为第二摄像头模组222的光轴，y2为第二摄像头模组222垂直于第二表面221时的光轴，也即参考线；在第二摄像头模组222的光轴x2相对于参考线y2朝向第二方位偏转的情况下，第二摄像头模组222相对于第二表面221所需调节的第二目标角度a2可以根据角度C以及第二摄像头模组222的焦平面与第二表面221之间的第一夹角b2确定，即a2＝b2-C/2，这里，C＝第一表面 211与第二表面221的折叠角度-π，也即可以按照以下公式：a2＝b2-(折叠角度-π)/2，确定第二摄像头模组222相对于第二表面221所需调节的第二目标角度a2，并按照第二目标角度a2调节第二摄像头模组222与第二表面221之间的相对角度。
可选地，目标摄像头模组与一角度调节结构连接，目标摄像头模组通过角度调节结构沿一支点中心轴相对于其所在表面转动，这里，支点中心轴可以设置于目标摄像头模组上与角度调节结构相对的一侧，或者，也可以设置于目标摄像头的底部；则步骤102，根据折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，可以包括以下步骤：根据折叠角度，确定角度调节结构的驱动参数；根据驱动参数，控制角度调节结构驱动目标摄像头模组，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度。本发明实施例中，可以预先设置折叠角度与角度调节结构的驱动参数之间的对应关系，进而基于折叠角度确定相应的驱动参数，并控制角度调节结构以该驱动参数驱动目标摄像头模组，实现对目标摄像头模组与其所在表面之间的相对角度的调整，使得第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，从而满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求。
可选地，在发明一些实施例中，在步骤102，根据折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度之后，该拍摄方法还可以包括：在相对角度调节完成后，发出提示信息。这样，用户即可基于该提示信息进行拍摄准备，从而更好地实现人机交互，提升用户拍摄体验。本发明实施例中，该提示信息可以包括文字提示信息、图案提示信息、语音提示信息和灯光提示信息中的至少一种。
较优地，在本发明实施例中，在相对角度调节完成的情况下，第一摄像头模组和第二摄像头模组的焦平面平行或处于同一平面，以使得第一摄像头模组和第二摄像头模组的拍摄平面平行或处于同一平面，满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求。
本发明实施例提供的拍摄方法，通过根据第一表面与第二表面的折叠角度，调节目标摄像头模组与其所在表面之间的相对角度，使第一摄像头模组和第二摄像头模组的焦平面间的夹角小于预设角度，然后在相对角度调节完成后，控制第一摄像头模组和第二摄像头模组进行拍摄，能够满足第一摄像头模组和第二摄像头模组共同拍摄的角度要求，保证多摄像头拍摄效果，提升用户拍摄体验。
