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。
参见图1，图1是本发明实施例提供的拍摄补光方法的流程图，本实施例提供的方法可以应用于电子设备中，如图1所示，包括以下步骤：
步骤101、显示拍摄预览界面，所述拍摄预览界面包括补光层。
其中，拍摄预览界面可以通过电子设备的摄像头获取得到，而拍摄预览界面一般显示在电子设备的显示屏幕上，而上述摄像头与上述显示屏幕可以位于同一侧。
其中，拍摄预览界面中的预览图像可以通过电子设备上的摄像头采集得到，而该摄像头可以为电子设备的前置摄像头或者后置摄像头，即：上述拍摄预览界面中的预览图像可以为通过前置摄像头采集的图像，也可以为通过后置摄像头采集的图像。
需要说明的是，本发明实施例中的电子设备可以具有多面显示屏幕(当具有两面屏幕时，则电子设备可以被称作为双面屏电子设备)，且每一显示屏幕均可以对应配置有摄像头。
步骤102、调节所述补光层的显示参数。
其中，本发明实施例的工作原理可以参见以下表述：
由于拍摄预览界面中包括补光层，通过调节补光层的显示参数(例如：透明度、亮度或者显示颜色等)，这样，可以调节补光层照射至拍摄对象(拍摄对象可以为电子设备所处环境中的对象，例如：可以位于朝向显示有拍摄预览界面的屏幕的方向上)的光照强度或色温，从而达到对拍摄对象进行补光的目的，因而可以调节电子设备通过摄像头获取的预览图像中拍摄对象(例如人脸)的亮度，进而增强预览图像的显示效果。需要说明的是，预览图像可以为显示在拍摄预览界面上的图像，例如：拍摄预览界面包括预览层，且补光层可以叠加显示在预览层之上，则预览图像可以为显示在预览层上的图像。
需要说明的是，补光层与预览层的具体类型在此不做限定，例如：补光层与预览层可以分别为两个图层，或者补光层与预览层可以分别为两个窗口。
其中，补光层对拍摄对象进行补光的原理可以参见以下表述：
当未设置有补光层时，拍摄预览界面通常显示的为预览图像，而在电子 设备所处环境的亮度较暗(例如不开灯的夜晚)时，预览图像通常为黑色图像；当增加补光层后，由于补光层通常可以为白色或者其他颜色(一般不为黑色)，这样，补光层发出的光线可以照亮拍摄对象(例如用户的人脸)，从而增强了预览图像中拍摄对象的显示亮度，即补光层完成了对拍摄对象的补光。当然，补光层的显示颜色不一样，对拍摄对象的补光效果不同，同时，补光层的透明度不一样，对拍摄对象的补光效果也不同。本发明实施例中，可以通过调节补光层的显示参数(例如：透明度、颜色或者显示亮度等参数)，从而完成对拍摄对象的补光效果的调整。
另外，补光层和预览层可以同时生成，当然，也可以先生成预览层，然后再生成补光层。例如：参见图2，电子设备显示预览层201，未显示补光层；参见图3，电子设备在预览层201上叠加显示补光层202，图3中斜线表示补光层202。
另外，作为一种可选的实施方式，预览层也可以叠加显示在补光层之上，这样，同样可以达到补光的效果，同时还可以对预览层上的预览图像起到补光效果。
其中，显示参数的具体类型在此不做限定，例如：显示参数可以包括透明度、显示颜色和显示亮度中的至少一种。
例如：当显示参数包括透明度，且当电子设备当前所处的外界环境中的显示亮度较低(低于亮度阈值，例如：亮度阈值可以为500尼特(nit))时，即此时外界环境可以认为是暗环境，而补光层的显示亮度可以为固定值，可以只调低补光层的透明度(例如可以调低为10％)，这样，增强了补光层照射至拍摄对象上的光照强度，从而增强了对拍摄对象的补光效果，进而使得电子设备通过摄像头获取的预览图像中的拍摄对象的亮度较高，从而增强了预览图像的显示效果。需要说明的是，在调低透明度的同时，还可以调高电子设备的屏幕的显示亮度，从而可以进一步增强对拍摄对象的补光效果。
举例对上面实施原理进行说明：当补光层的透明度较低时，预览层上的光线透过补光层照射至用户的光线数量少，即此时对用户进行补光的光线多数为补光层上的光线，而当补光层的透明度较高时，预览层上显示预览图像发出的光线可以透过补光层对用户进行补光，而此时预览层上的预览图像通 常较暗(外界环境的亮度较暗)，从而导致对用户补光效果较差。
另外，在补光层完成对拍摄对象的补光之后，拍摄对象(例如：人)还可以根据拍摄图像的需要改变拍照姿势，调整美颜或者滤镜等功能，从而使得电子设备获取的预览图像呈现更好的显示效果。
当然，当电子设备所处环境中的显示亮度较高(高于亮度阈值)时，即此时所处环境可以认为是亮环境，则此时电子设备获取预览图像时，无须补光，因此可以调高补光图层的透明度(例如可以调高为100％)，使得补光图层不影响预览图像的正常显示。
需要说明的是，电子设备可以根据用户的输入指令来进行调节补光层的显示参数，例如：输入指令可以为语音指令，当然，也可以是针对拍摄预览界面上的控件的触控指令，具体类型在此不做限定。
另外，电子设备也可以根据当前所处的外界环境的环境参数自动调节补光层的显示参数，例如：当外界环境的亮度较高时，电子设备可以根据外界环境的光照强度调高补光图层的透明度(同时也可以调低电子设备的显示亮度或者不调整电子设备的显示亮度)；当外界环境的亮度较暗时，电子设备可以根据外界环境的光照强度调低补光图层的透明度，同时还可以调高电子设备的显示亮度。
另外，电子设备同样还可以调节补光层的颜色，由于不同的颜色发出的光的色温值不同，因而对拍摄对象的补光效果也不同，这样，通过调节补光层的显示颜色，同样可以增强对拍摄对象的补光效果，进而增强电子设备通过摄像头采集的预览图像的显示效果。
其中，可以根据电子设备所处环境的色温值调整补光层的显示颜色，例如：当所处环境的色温值较低时，可以将补光层的显示颜色自动切换为黄光，而其他情况下可以将补光层的显示颜色切换为白光。这样，可以根据所处环境的色温值的不同，自适应的调整补光层的显示颜色，从而增强了补光层对拍摄对象的补光效果。
另外，作为一种可选的实施方式，还可以根据所处环境的亮度值来切换补光层的显示颜色，即当电子设备的所处环境为亮环境时，则可以调整补光层的显示颜色为偏冷颜色；当电子设备的所处环境为暗环境时，则可以调整 补光层的显示颜色为偏暖颜色，这样，补光层的显示颜色可以根据亮环境和暗环境的不同来进行调节，从而可以进一步增强对拍摄对象的补光效果。下面举例说明：
当光照度(表示被摄主体表面单位面积上受到的光通量)在0—300范围内补光层的显示颜色可以为暖色系颜色，从而进行补光；在300—500范围内补光层的显示颜色可以为冷色系颜色，从而进行补光；大于500时则不显示补光层。需要说明的是，光照度的单位为勒克斯(lux)。同时，光照度和亮度值为用于表示电子设备所处环境的光照条件的不同参数。
本发明实施例中，上述电子设备可以是手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(Personal Digital Assistant，PDA)、移动上网装置(Mobile Internet Device，MID)或可穿戴式设备(Wearable Device)等等。
在本发明实施例中，拍摄补光方法包括：显示拍摄预览界面，所述拍摄预览界面包括补光层；调节所述补光层的显示参数。这样，由于拍摄预览界面中包括补光层，且补光层的光线可以照射至拍摄对象上，从而增强了摄像头获取的图像中拍摄对象的显示亮度，进而增强了图像的显示效果。
参见图4，图4是本发明实施例提供的拍摄补光方法的流程图。本实施例与上个实施例的主要区别在于：电子设备可以根据获取的所处环境的环境参数，调节补光层的显示参数。如图4所示，包括以下步骤：
步骤401、显示拍摄预览界面，所述拍摄预览界面包括补光层。
其中，拍摄预览界面可以通过电子设备的摄像头获取得到，而拍摄预览界面一般显示在电子设备的显示屏幕上，而上述摄像头与上述显示屏幕可以位于同一侧。
需要说明的是，本发明实施例中的电子设备可以具有多面显示屏幕(当具有两面屏幕时，则电子设备可以被称作为双面屏电子设备)，且每一显示屏幕均可以对应配置有摄像头。
步骤402、获取所述电子设备所处环境的环境参数，其中，所述环境参数包括以下至少一项：环境亮度值和色温值。
其中，电子设备可以通过摄像头或者光线传感器等元器件采集所处环境 的环境参数。
步骤403、基于所述环境参数，调节所述补光层的显示参数；所述显示参数包括以下至少一项：透明度、亮度和显示颜色。
可选地，当环境参数包括环境亮度值时，则显示参数可以包括透明度；当环境参数包括色温值时，则显示参数可以包括显示颜色。
例如：当环境参数包括环境亮度值时，则可以根据环境亮度值调节补光层的透明度，例如：参见图5，调节透明度之后的补光层501；当环境参数包括色温值时，则可以根据色温值调节补光层的颜色。
需要说明的是，当调节补光层的颜色时，电子设备(即屏幕)的显示亮度可以一同调整，当然，也可以不调整电子设备的显示亮度，具体方式在此不做限定。
可选地，当环境参数包括环境亮度值时，显示参数也可以包括显示颜色，即可以根据电子设备当前所处环境的环境亮度值来调节补光层的显示颜色。即电子设备当前所处环境为亮环境时，补光层可以以偏冷颜色显示，同时，还可以控制电子设备采用偏冷光源发光；电子设备当前所处环境为暗环境时，补光层可以以偏暖颜色显示，同时，还可以控制电子设备采用偏暖光源发光。这样，可以进一步的增强对拍摄对象的补光效果，同时，还可以使得电子设备上呈现不同的颜色显示，增强显示效果。
可选地，在所述环境参数包括环境亮度值的情况下，所述显示参数包括透明度；
所述基于所述环境参数，调节所述补光层的显示参数，包括：
基于所述环境亮度值以及预设的亮度阈值，计算目标透明度；
调节所述补光层的透明度为所述目标透明度。
其中，基于环境亮度值与预设的亮度阈值计算目标透明度的具体方式在此不做限定。
例如：作为一种可选的实施方式，可以比较环境亮度值与亮度阈值的大小，当环境亮度值大于亮度阈值时，可以计算得到目标透明度等于第一透明度，则可以将当前的透明度增大至第一透明度(大于预设的透明度即可)；当环境亮度值小于亮度阈值时，可以计算得到目标透明度等于第二透明度，则 可以将当前的透明度减小至第二透明度(小于预设的透明度)。
需要说明的是，增大的幅度以及减小的幅度在此不做限定，例如：当环境亮度值与亮度阈值越接近时，增大的幅度或者减小的幅度越小；当环境亮度值与亮度阈值之间的差值越大时，增大的幅度或者减小的幅度越大。
当然，作为另一种可选的实施方式，还可以根据环境亮度值与亮度阈值的比值来计算目标透明度，例如：当环境亮度值与亮度阈值的比值为1时，则目标透明度为100％；当环境亮度值与亮度阈值的比值为0.5时，则目标透明度为50％；当环境亮度值与亮度阈值的比值为2时，则目标透明度为200％。
本发明实施方式中，通过环境亮度值和亮度阈值计算目标透明度，这样，可以使得目标透明度的计算结果与环境亮度值具有相关性，从而使得目标透明度可以更加准确的反应电子设备所处环境中的亮度情况，从而使得对拍摄对象的补光结果更加准确，补光效果更好。
其中，作为一种可选的实施方式，所述基于所述环境亮度值以及预设的亮度阈值，计算目标透明度，包括：
根据预设公式T＝A×L/Y×B，计算目标透明度；
其中，T为所述目标透明度，A为常数，L为所述环境亮度值，Y为所述亮度阈值，B为100％。
其中，A的具体取值范围在此不做限定，可以根据实验进行总结得到。不同的实验条件下，其具体取值可能不同。
其中，亮度阈值的具体取值在此也不做限定，例如：亮度阈值可以为500尼特，需要说明的是，全文中的环境亮度值或者亮度阈值的单位均可以为尼特(nit)。
其中，环境亮度值也可以被称作为当前环境亮度，亮度阈值也可以被称作为亮度临界值。
例如：亮度阈值为500尼特，环境亮度值小于500尼特时则为暗环境，环境亮度值大于或等于500尼特时则为亮环境。
当环境亮度值大于或者等于500尼特时，处于亮环境，此时不需要补光，即可以调节补光层的目标透明度为100％，补光层全透明，用户看不到补光画面，对于体验无任何影响。当环境亮度值为0时，处于最暗环境，此时计算 得到目标透明度为0，即补光层完全不透明，完全补光，需要说明的是，当目标透明度为0时，可以调大屏幕的显示亮度，作为一种可选的实施方式，可以调节屏幕的显示亮度为最大值。当然，作为另一种可选的实施方式，也可以调大补光层的显示亮度。
本发明实施方式中，通过上述预设公式计算目标透明度，这样，可以使得目标透明度的计算方式更加简便，且计算结果更加准确。
可选地，所述获取所述电子设备所处环境的环境参数之后，所述方法还包括：
基于所述环境参数，调节所述电子设备的屏幕的显示亮度。
例如：当环境参数包括环境亮度值时，当调低补光层的透明度之后，可以调高屏幕的显示亮度。另外，当环境参数包括色温值时，根据色温值将补光层的显示颜色由冷色系变为暖色系后，同样可以提高屏幕的显示亮度。
当然，也可以基于环境参数调低屏幕的显示亮度。
本发明实施方式中，由于可以调节屏幕的显示亮度，这样，当调高屏幕的显示亮度时，同样可以增强照射至拍摄对象上的光照强度，从而进一步增强对拍摄对象的补光效果。
可选地，在所述环境参数包括色温值的情况下，所述显示参数包括显示颜色；其中，所述显示颜色与所述色温值相关联。
在本实施方式中，由于不同的颜色发出的光的色温值不同，因而对拍摄对象的补光效果也不同，这样，通过调节补光层的显示颜色，同样可以增强对拍摄对象的补光效果，进而增强电子设备通过摄像头采集的预览图像的显示效果。其中，可以根据电子设备所处环境的色温值调整补光层的显示颜色，例如：当所处环境的色温值较低时，可以将补光层的显示颜色自动切换为黄光，而其他情况下可以将补光层的显示颜色切换为白光。这样，可以根据所处环境的色温值的不同，自适应的调整补光层的显示颜色，从而增强了补光层对拍摄对象的补光效果。
本发明实施例中，通过步骤401至403，由于电子设备可以获取所处环境的环境参数，并基于环境参数调节补光层的显示参数，这样，使得电子设备可以自动调节补光层的显示参数，从而可以增强电子设备的智能化程度， 进而增强用户体验。
需要说明的是，当调节补光层的显示参数后，参见图6，拍摄预览界面上可以显示有预览图像601后，用户可以调整自己的姿势，且电子设备可以采集到目标图像，其中，目标图像可以为补光层对完成补光之后的拍摄对象(可以是用户)进行采集得到的图像，同时，也可以为对完成姿势调整之后的用户进行采集得到的图像。
另外，在完成采集目标图像后，电子设备可以持续获取环境参数，并可以基于环境参数持续调节补光层的显示参数。
参见图7，图7是本发明实施例提供的拍摄补光方法的流程图。本实施例与上个实施例的主要区别在于：用户可以通过对目标控件的输入来调节补光层的显示参数。如图7所示，包括以下步骤：
步骤701、显示拍摄预览界面，所述拍摄预览界面包括补光层，所述拍摄预览界面还包括目标控件。
其中，拍摄预览界面和补光层的表述可以参见上述实施例中的相应表述，在此不再赘述。
步骤702、接收用户对所述目标控件的第一输入。
其中，第一输入的类型在此不做限定，例如：第一输入可以为语音输入，也可以为滑动输入或者触控输入等。
步骤703、响应于所述第一输入，调节所述补光层的显示参数。
其中，目标控件的具体类型在此不做限定，例如：目标控件可以为条状控件，当然，目标控件也可以为环形控件。
其中，显示参数也可以参见上述实施例中的相应表述，具体在此不再赘述。需要说明的是，每一种显示参数均可以对应有一个控件，例如：参见图8和图9，图8中显示有透明度调节控件801，图9中显示有目标控件901，且目标控件901可以为显示颜色调节控件901，当然，图10中还显示有显示亮度调节控件1001(可以用于调节补光层的显示亮度)。当然，作为另一种可选的实施方式，多种显示参数均可以共用同一个目标控件，可以通过指令切换目标控件控制的显示参数的种类。
可选地，所述显示参数包括显示颜色，所述目标控件包括目标子控件和 至少一个颜色标识；
所述接收用户对所述目标控件的第一输入，包括：

所述响应于所述第一输入，调节所述补光层的显示信息，包括：
响应于所述第一输入，调节所述补光层的显示颜色为目标颜色，所述目标颜色标识与所述目标颜色对应。
其中，参见图9，目标控件901可以呈环形设置，而目标子控件9011可以呈圆形设置，且可以位于目标控件901的预设区域(可以为中心区域或者中心偏左的区域等)，而目标控件901还可以包括四个颜色标识，上述四个颜色标识沿逆时针方向依次可以分别为第一颜色标识9012、第二颜色标识9013、第三颜色标识9014和第四颜色标识9015，即上述四个颜色标识可以位于目标控件901的环形区域上。每一种颜色标识可以表示一种颜色，例如：第一颜色标识9012可以表示黄色、第二颜色标识9013可以表示淡绿色、第三颜色标识9014可以表示深蓝色、第四颜色标识9015可以表示黑色。
这样，通过移动目标子控件至目标颜色标识所在的区域，即可选定目标颜色，进而可以将补光层的颜色切换为目标颜色。
本发明实施方式中，通过目标子控件与颜色标识完成对目标颜色的选择，增加了目标颜色确定方式的多样性和灵活性。
可选地，所述预览界面还包括预览层，所述补光层叠加显示于所述预览层之上，且所述补光层包括镂空区域。
其中，镂空区域可以为透明度为大于预设阈值的补光层区域，参见图12，图12中包括预览层1201和补光层1202，其中，补光层1202包括镂空区域12022，而预览层1201上可以显示有预览图像12011，当然，镂空区域也可以为不设置补光层的区域，具体类型在此不做限定。
其中，预设阈值的具体取值在此不做限定，例如：预设阈值可以为50％、70％或者100％等。这样，由于镂空区域为透明度较高的补光层区域，从而使得用户可以清楚的看到预览层上的预览图像，进而使得预览图像的显示效果 较好。
其中，本发明实施方式也可以应用于上述实施例中。
本发明实施方式中，由于设置有镂空区域，则使得用户可以通过镂空区域观察预览层上的预览图像，这样，使得用户既可以观察到自己在预览图像上的姿势，并可以调整自己的姿势，同时还可以实现对用户的补光。
可选地，所述显示拍摄预览界面之后，所述方法还包括：
接收用户的第二输入；
响应于所述第二输入，更新所述补光层的镂空区域的显示。
其中，第二输入的表述也可以参见上述实施例中第一输入的相应表述，具体在此不再赘述。
其中，更新补光层的镂空区域的显示的具体方式在此不做限定，例如：可以更新镂空区域的形状、尺寸或者透明度等。
本发明实施方式中，由于可以根据用户的输入更新镂空区域的显示，从而进一步的增强了电子设备的智能化程度，提升了用户体验。
其中，本发明实施方式同样也可以应用于上述实施例中。
可选地，所述更新所述补光层的镂空区域的显示，包括以下至少一项：

其中，例如：可以将镂空区域的形状由圆形更新为椭圆形；可以将镂空区域的尺寸调大或者调低；可以将透明度调高或者调低。
当然，还可以更新镂空区域的显示颜色或者显示亮度等。
这样，本发明实施方式中，由于可以更新镂空区域的形状、尺寸和透明度等，从而增加了更新镂空区域的显示的多样性，进而使得镂空区域的显示更加灵活。
其中，本发明实施方式同样也可以应用于上述实施例中。
本发明实施例中，通过步骤701至703，用户可以通过目标控件来调节补光层的显示参数，从而增加了调节方式的多样性和灵活性。
需要说明的是，当调节补光层的显示参数后，参见图11，拍摄预览界面 上可以显示有预览图像1101后，用户可以调整自己的姿势，且电子设备可以采集到目标图像，其中，目标图像可以为补光层对补光之后的拍摄对象(可以是用户)进行采集得到的图像，同时，也可以为对调整姿势之后的用户进行采集得到的图像。
