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做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。
请参阅图1，图1为本发明其中一实施方式提供的一种电子设备的正面示意图。电子设备100包括第一主体10及第二主体20。第一主体10可相对第二主体20转动。第一主体10与第二主体20均包括正面和与所述正面相对的背面。电子设备100还包括设置于第一主体10正面上的第一显示屏31和设置于第二主体20正面上的第二显示屏33，第一显示屏31和第二显示屏33的显示面与所述正面朝向相同。本实施方式中，第一显示屏31与第二显示屏33一体设置构成显示屏30。可以理解，第一显示屏31与第二显示屏33可以为相互独立设置的刚性屏或柔性屏。
请参阅图2-3，图2为图1所示的电子设备的背面示意图，图3为图1所示的电子设备的立体分解示意图。电子设备100还包括驱动机构40、第一拍摄装置50及控制器60。第一拍摄装置50设于第一主体10的背面并与控制器60电性连接。第二主体20对应第一拍摄装置50设有透光区201。透光区201内形成第一通孔21。当电子设备100处于折叠状态(如图4所示)时，第二主体20上的第一通孔21的位置与第一拍摄装置50正对。
换而言之，第二主体20上在折叠状态下与第一拍摄装置50正对的位置处设有贯穿第二主体20的正面和背面的第一通孔21。当电子设备100处于折叠状态时，控制器60能够控制驱动机构40驱动第一拍摄装置50从第一主体10的背面凸出并收容于第一通孔21内， 第一拍摄装置50通过第一通孔21拍摄第二主体20正面朝向的景物。
所述折叠状态为第一主体10与第二主体20叠合于一起的状态。电子设备100处于折叠状态时，第一主体10与第二主体20之间的夹角为0度。所述展开状态为第一主体10与第二主体20未叠合于一起的状态，即，折叠状态之外的状态，例如，第一主体10与第二主体20展开且位于同一个平面的状态时，即第一主体10与第二主体20之间的夹角为180度。本实施方式中，所述电子设备100处于展开状态时，第一主体10与第二主体20之间的夹角大于0度小于或等于180度。可以理解的是，在其他实施例中，当电子设备100处于折叠状态时，第一主体10与第二主体20之间的夹角小于等于一角度阈值。例如，所述角度阈值可以为10°。需要说明的是，本发明所称的折叠状态及展开状态均为相对的概念，即只要一个状态的展开程度大于另一个状态的展开程度，那么即可认为前者是展开状态，后者是折叠状态。
本实施方式中，控制器60能够在电子设备100处于折叠状态且有拍摄需求时控制第一拍摄装置50伸入第一通孔21，从而能够使第一拍摄装置50通过第一通孔21拍摄第二主体20的正面朝向的景物。所述确定有拍摄需求为，控制器60获取拍摄模式启动指令。显示屏30为触摸显示屏，所述拍摄模式启动指令可为用户通过对显示屏30的触摸操作开启第一拍摄装置50并选择拍摄模式的指令。可以理解，所述拍摄模式启动指令也可通过其它方式产生，例如，用户通过按压电子设备100上的按键等等。可以理解，也可以在电子设备100处于折叠状态但无拍摄需求时，控制器60能够控制第一拍摄装置50伸入第一通孔21。
本实施方式提供的电子设备100，当电子设备100处于折叠状态且确定有拍摄需求时，控制器60控制第一拍摄装置50伸入第一通孔21，第一拍摄装置50即可作为前置摄像头实现自拍功能，提高了电子设备100的使用便利性，方便用户的使用。当电子设备100处于展开状态时，第一拍摄装置50可作为后置摄像头使用。
在一实施例中，电子设备100还包括连接件70，第一主体10与第二主体20通过连接件70转动连接。可以理解，连接件70可以为转轴、铰链结构、皮革、可弯折性金属等。显示屏30可跟随第一主体10相对于第二主体20的转动而弯折。可以理解，连接件70可以省略。
在一实施例中，第一通孔21的孔径在第二主体20的正面向第二主体20的背面的方向上逐渐增大，用于方便第一拍摄装置50伸入及退出。本实施方式中，第一主体10、第二主体20与显示屏30共同形成容纳空间101。第一主体10的背面上开设与容纳空间101连通的开孔13。
驱动机构40、第一拍摄装置50与控制器60收容于容纳空间101，第一拍摄装置50能够通过开孔13伸出或退回第一主体10。电子设备100还包括电池41，用于对第一拍摄装置50、控制器60等器件进行供电。在另一实施例中，电子设备100还包括按键42，按键42包括音量按键、电源按键等。按键42可设置于第一主体10或第二主体20的侧边。
请参阅图5，图5为本发明其中一实施方式提供的驱动机构与第一拍摄装置的立体组装示意图。驱动机构40包括驱动件41及传动件43。传动件43与第一拍摄装置50固定连接。驱动件41能够通过传动件43驱动第一拍摄装置50向第一方向运动或向第二方向运动， 所述第一方向为第一主体10的正面指向所述第一主体10的背面的方向，所述第二方向与所述第一方向相反。驱动件41能够通过传动件43驱动第一拍摄装置50伸出或缩回第一主体10。
本实施方式中，驱动机构40还包括支架45，驱动件41为旋转电机，驱动件41的转动轴411能够转动地穿设于支架45，支架45用于增强第一拍摄装置50的运动稳定性。传动件43与驱动件41的转动轴411连接，传动件43啮合于驱动件41的转动轴411上。驱动件41的转动轴411沿第一转向(例如顺时针)旋转时，带动传动件43伸展并推动第一拍摄装置50向所述第一方向运动，使得第一拍摄装置50伸出开孔13，而在电子设备100处于折叠状态时使得第一拍摄装置50进入第一通孔21。驱动件41的转动轴411沿第二转向(例如逆时针)旋转时，带动传动件43拉动第一拍摄装置50向所述第二方向运动，进而使第一拍摄装置50回缩，而实现退出第一通孔21。另外，传动件43包括多个齿条431，驱动件41的转动轴411与传动件43通过齿条431相互咬合，用于使传动件43能够稳固地啮合于驱动件41的转动轴411上，避免影响第一拍摄装置50的拍摄性能。
可以理解，不限定驱动件41为旋转电机，驱动件41可以为其他驱动结构，例如直线电机、气缸等，驱动件41能够实现驱动第一拍摄装置50作伸缩运动即可，传动件43可以省略。
请参阅图6所示，图6为本发明实施方式提供的电子设备处于折叠状态时第一拍摄装置未伸入第一通孔时的状态示意图。第二显示屏33上开设与第一通孔21对应的第二通孔35(又如图1所示)，第一通孔21与第二通孔35连通形成通道。光能够从第二通孔35射入所述通道，即第一拍摄装置50可朝向第二显示屏33一侧进行拍摄。如图6所示，电子设备100还包括第一光学模组70，第一光学模组70位于所述通道中，且当第一拍摄装置50伸入第一通孔21时，第一光学模组70位于第一拍摄装置50的光路的前方，即位于第一光学模组70相对于第一拍摄装置50更靠近第二显示屏33的外侧，第一光学模组70与第一拍摄装置50组成第二拍摄装置。本实施方式中，第一光学模组70设置于第一通孔21上与第二通孔35相邻的一端，第一光学模组70包括至少一个透镜。在其他实施例中，第一光学模组70包括多个透镜，并固定设置于第一通孔21内。当电子设备100处于折叠状态时，开孔13与所述通道正对，第一拍摄装置50可通过开孔13伸出或缩回第一主体10。
在一些实施例中，第二显示屏33也可不开设第二通孔35，所述透光区201内也可不设置第一通孔21。第二显示屏33为透明材料制成，控制器60在控制第一拍摄装置50进行拍摄时，还控制显示屏30对应第一拍摄装置50的预设区域不显示而呈现透明效果，从而光线可通过所述预设区域，而使得第一拍摄装置50可进行拍摄。在另一实施例中，所述透光区201内开设有第一通孔21，从而光线可通过所述预设区域进入第一通孔21，而使得第一拍摄装置50可进行拍摄。换而言之，当电子设备100处于折叠状态时，控制第二显示屏33上对应于第一拍摄装置50的预设区域不显示。所述透光区201位于所述预设区域内，所述预设区域在同一面上的投影面积大于或等于所述透光区在同一面上的投影面积。第一拍摄装置50可通过透光区201和所述预设区域获取所述第二主体20正面朝向的景物。
请参阅图7所示，图7为本发明实施方式提供的电子设备处于折叠状态时第一拍摄装置伸入第一通孔时的状态示意图。当电子设备100处于折叠状态时，控制器60能够控制驱 动机构40驱动所述第一拍摄装置50运动以改变第一光学模组70和第一拍摄装置50的间距，并通过改变后的所述间距改变所述第二拍摄装置的视场角(Angle of View，FOV)，有利于提高拍摄图像的质量。
请参阅图8所示，图8为第二拍摄装置的成像原理示意图。根据焦距公式Φ＝Φ1+Φ2-t×Φ1×Φ2，其中Φ为所述第二拍摄装置的组合光焦度，Φ1为第一拍摄装置50的光焦度，Φ2为第一光学模组70的光焦度，t为第一拍摄装置50和第一光学模组70之间的间距，通过改变间距t，达到组合光焦度Φ的变化。
根据视场角FOV＝2×artan(Φ×y/2)，其中y为第一拍摄装置50的图像传感器的感应区域的高度。由于第一拍摄装置50的图像传感器的感应区域的高度y为固定尺寸，改变组合光焦度Φ，就可以改变整体的视场角FOV。本实施方式中，第一拍摄装置50的焦距为4mm，第一拍摄装置50的相对孔径，即第一拍摄装置50的F数(光圈数)为2.2，第一光学模组70的焦距为-8.5mm，第一光学模组70位于第一通孔31。本实施方式中，第一拍摄装置50的视场角范围为80°-90°。请参阅图9a，当t为t1(例如2mm)时，视场角FOV为80°；请参阅图9b，当t为t2(例如2.5mm)时，视场角FOV为86°；请参阅图9c，当t为t3(例如3mm)时，视场角FOV为90°。
在一实施方式中，第一拍摄装置50包括第二光学模组，所述第二光学模组包括多个透镜；当电子设备100处于折叠状态且第一拍摄装置50伸入所述第一通孔21时，控制器60能够控制改变所述第二光学模组的相邻所述透镜的间距以改变所述第二光学模组的光焦度，从而改变第一拍摄装置50的视场角。
在一些实施例中，透光区201的第一通孔21可以省略，当电子设备100处于展开状态时，控制器60能够控制第一拍摄装置50拍摄第一主体10背面朝向的景物；当电子设备100处于折叠状态时，控制器60控制第一拍摄装置50通过透光区201拍摄第二主体20的正面朝向的景物。进一步地，当电子设备100处于折叠状态时，控制器60能够控制第一拍摄装置50从第一主体10的背面凸出并伸入透光区201内；电子设备100处于展开状态时，所述控制器能够控制所述第一拍摄装置缩入所述第一主体内。电子设备100处于展开状态时，第一拍摄装置50能够直接取景；电子设备100处于折叠状态时，第一拍摄装置50透过透光区201取景。
请参阅图10，图10为本发明实施方式提供的电子设备的结构框图。电子设备100还包括检测器80。控制器60与检测器80电性连接，检测器80用于检测电子设备100所处状态，电子设备100的所处状态包括折叠状态和展开状态。本实施方式中，检测器80为一设于第一主体10背面上的触发开关(如图2所示)，当第一主体10与第二主体20叠合于一起时，第二主体20触碰到检测器80，检测器80受到压力被触发进而产生第一检测信号，控制器60依据所述第一检测信号，确定电子设备100处于折叠状态。当电子设备100从折叠状态转换为展开状态时，即第二主体20相对第一主体10转动时，检测器80从受压状态被释放进而产生第二检测信号，控制器60依据所述第二检测信号，确定电子设备100处于展开状态。
当检测器80检测到电子设备100处于折叠状态时，控制器60控制驱动件41驱动第一拍摄装置50伸入第一通孔21，第一拍摄装置50能够第二主体20的正面一侧获取图像。
当检测器80检测到电子设备100从折叠状态转换为展开状态时，控制器60控制驱动件41驱动第一拍摄装置50从第一通孔21退出，避免对驱动机构40、第一拍摄装置50、第一主体10、第二主体20等结构造成损坏。
可以理解，检测器80也可以设于第二主体20上；检测器80也可以为其他类型的检测装置，例如在第一主体10上设红外发射器，在第二主体20设红外接收器。
在一实施方式中，检测器80可以为陀螺仪等，通过所述陀螺仪检测电子设备100的第一主体10与第二主体20的加速度或角速度等信息，控制器60通过检测器80检测到的加速度或角速度等信息进行处理，控制器60获取第一主体10与第二主体20之间的夹角，所述展开状态为检测器80检测到第一主体10与第二主体20之间的夹角大于角度阈值时电子设备100所处的状态，例如，所述角度阀值为10度。
当电子设备100处于折叠状态时，显示屏30弯折为第一显示屏31(如图11a所示)及第二显示屏33(如图11b所示)，第一显示屏31对应第一主体10，第二显示屏33对应第二主体20。
控制器60包括一个或多个处理器。处理器用于完成电子设备100的各种控制逻辑，其可以为通用处理器、数字信号处理器(DSP)、专用集成电路(ASIC)、现场可编程门阵列(FPGA)、单片机、ARM(Acorn RISC Machine)或其它可编程逻辑器件、分立门或晶体管逻辑、分立的硬件组件或者这些部件的任何组合。还有，处理器还可以是任何传统处理器、微处理器或状态机。处理器也可以被实现为计算设备的组合，例如，DSP和微处理器的组合、多个微处理器、一个或多个微处理器结合DSP核、或任何其它这种配置。
电子设备100还包括存储器90。存储器90作为一种非易失性计算机可读存储介质，可用于存储非易失性软件程序、非易失性计算机可执行程序以及模块，如本发明实施例中的拍照过程对应的程序指令/单元。所述处理器通过运行存储在存储器90中的非易失性软件程序、指令以及单元，从而执行电子设备100的各种功能应用以及数据处理。
存储器90可以包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需要的应用程序；存储数据区可存储根据电子设备100使用所创建的数据等。此外，存储器90可以包括高速随机存取存储器，还可以包括非易失性存储器，例如至少一个磁盘存储器件、闪存器件、或其他非易失性固态存储器件。在一些实施例中，存储器90可选包括相对于处理器远程设置的存储器，这些远程存储器可以通过网络连接至电子设备100。上述网络的实例包括但不限于互联网、企业内部网、局域网、移动通信网及其组合。一个或者多个单元存储在存储器90中，当被一个或者多个处理器执行时，执行上述任意方法实施例中的自拍方法。
在一应用场景中，控制器60获取用户的拍摄模式启动指令以确定拍摄需求。当检测器80检测到电子设备100处于折叠状态时，控制器60控制驱动件41驱动第一拍摄装置50伸入第一通孔21。第一拍摄装置50获取画面。控制器60控制在第二显示屏33显示预览画面。控制器60控制驱动件41驱动第一拍摄装置50在所述通道内运动，调节第一拍摄装置50与第一光学模组70之间的间距，进行自动调焦。第二显示屏33上显示拍摄按钮，所述拍摄按钮包括拍照按钮和录像按钮。当用户触摸拍摄按钮时产生拍照指令，控制器60根据所述拍照指令控制第一拍摄装置50获取图像完成拍摄。若检测器80检测到电子设备100 由折叠状态转换为展开状态时，控制器60控制驱动件41驱动第一拍摄装置50从第一通孔21退出。可以理解，在电子设备100完成自动调焦后，第一拍摄装置50也可自动摄取图像完成自拍。
在一应用场景中，在控制器60控制在第二显示屏33显示预览画面时，控制器60可根据用户对按键42的触发操作而控制第一拍摄装置50摄取图像。
