技术领域
本公开实施例涉及通信技术领域，尤其涉及一种拍摄方法及电子设备。
背景技术
随着电子设备技术的发展，用户使用电子设备(例如，智能手机)的频率越来越高，电子设备的拍照功能逐渐成为用户的常用功能之一。一般的，传统的摄像设备在拍摄照片时，通常可以通过调节摄像头的光圈(即摄像头中用来控制光线透过镜头，进入机身内感光面光量的装置)、快门以及感光度(International Standardization Organization，简称ISO)值来得到合适的亮度，从而拍摄出满意的照片。
然而，针对传统的具有屏下摄像头的电子设备来说，由于受到电子设备的厚度限制，电子设备中的屏下摄像头通常采用固定光圈，如此，当用户在使用电子设备拍摄照片时，由于进光量固定，很可能会导致拍摄效果较差。
发明内容
本公开实施例提供一种拍摄方法及电子设备，以解决由于传统的具有屏下摄像头的电子设备采用固定光圈，所导致的拍摄效果较差的问题。
为了解决上述技术问题，本公开是这样实现的：
第一方面，本公开实施例提供一种拍摄方法，应用于包括显示屏和摄像头的电子设备，且该摄像头位于该显示屏下方，该显示屏包括第一偏光 片和第二偏光片，该第一偏光片与该第二偏光片之间具有液晶，该方法包括：
将显示屏的电极电压调节为目标电压值；其中，当上述显示屏的电极电压为上述目标电压值时，该显示屏的光线透过率满足预设条件；通过上述摄像头获取第一图像。
第二方面，本公开实施例还提供了一种电子设备，该电子设备包括显示屏和摄像头，该摄像头位于该显示屏下方，该显示屏包括第一偏光片和第二偏光片，该第一偏光片与该第二偏光片之间具有液晶，该电子设备包括：
调节模块，用于将显示屏的电极电压调节为目标电压值；其中，当上述显示屏的电极电压为上述目标电压值时，该显示屏的光线透过率满足预设条件；获取模块，用于通过上述摄像头获取第一图像。
第三方面，本公开实施例提供了一种电子设备，包括处理器、存储器及存储在该存储器上并可在该处理器上运行的计算机程序，该计算机程序被该处理器执行时实现如第一方面所述的拍摄方法的步骤。
第四方面，本公开实施例提供了一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现如第一方面所述的拍摄方法的步骤。
在本公开实施例中，电子设备通过将该电子设备的显示屏的电极电压调节为目标电压值，并在该电子设备的显示屏的电极电压为目标电压值时，通过该电子设备的摄像头获取第一图像。由于当该电子设备的显示屏的电极电压为该目标电压值时，该电子设备的显示屏的光线透过率满足预设条件，因此，本公开实施例可以在电子设备的显示屏的光线透过率满足预设条件时拍摄，从而使拍摄结果更符合用户的具体需求。

下面结合图4所示的拍摄方法流程图对本公开实施例的拍摄方法进行说明，图4为本公开实施例提供的一种拍摄方法流程示意图，该方法包括步骤201和步骤202：
步骤201：电子设备将显示屏的电极电压调节为目标电压值。
其中，当该电子设备的显示屏的电极电压为该目标电压值时，该电子设备的显示屏的光线透过率满足预设条件。
示例性的，上述电子设备的显示屏的光线透过率满足预设条件是指：上述电子设备的显示屏的光线透过率达到预定光线透过率。
其中，可选地，上述预定光线透过率可以为：目标光圈值对应的显示屏的光线透过率。当然，上述光线透过率满足预设条件还可以是指光线透 过率低于预定光线透过率、光线透过率与电子设备当前场景相匹配等，本公开实施例对此不作具体限定。
示例性的，显示屏的光线透过率与光圈值对应的光线透过率相关。如此，终端设备便可以通过调节电压值，来将显示屏的光圈调节至适当的光圈值。
步骤202：电子设备通过该电子设备的摄像头获取第一图像。
本公开实施例提供的拍摄方法，通过将电子设备的显示屏的电极电压调节为目标电压值，并在该电子设备的显示屏的电极电压为目标电压值时，通过该电子设备的摄像头获取第一图像。由于当该电子设备的显示屏的电极电压为该目标电压值时，该电子设备的显示屏的光线透过率满足预设条件，因此，本公开实施例可以在电子设备的显示屏的光线透过率满足预设条件时拍摄，从而使拍摄结果更符合用户的具体需求。
可选地，在本公开实施例中，上述的步骤201之后，该方法还可以包括如下步骤：
步骤A：电子设备在拍摄界面中，显示目标电压值对应的目标光圈信息。
示例性的，上述目标光圈信息包括以下至少一项：光圈图案，光圈值。其中，上述的光圈图案能够表征电子设备中摄像头的实时光圈值，即上述光圈图案可以及时向用户反馈实时的光圈值。
在一种示例中，电子设备在调节显示屏的电极电压时，可以在拍摄界面中实时显示对应光圈值的大小，从而及时向用户反馈实时的光圈值。
举例说明，以电子设备为手机为例，如图5所示，该手机包括：摄像头(即图5中的40)和显示屏(即图5中的41)，该摄像头位于显示屏顶部。当用户使用手机进行拍摄时，手机显示拍摄界面(即图5中的42)，当手机确定到目标光圈值后，将显示屏的电极电压调节为目标电压值，并在该拍摄界面的拍摄控件的上方显示该目标电压值对应的目标光圈值(即图5中的43，例如，图5所示的F＝2.0)。
可选地，在本公开实施例中，在上述步骤201之前该方法还包括：
步骤301：电子设备确定摄像头的目标光圈值。
应注意的是，本公开实施例中的光圈值并不是一个真正光圈的光圈值，只是该电子设备中的摄像头与其他具有可调节光圈的摄像头相比，具有相同的光圈效果。即，本公开实施例中的目标光圈值可以表征一个特定光圈效果。
进一步的，上述的步骤202可以包括以下步骤302：
步骤302：电子设备将显示屏的电极电压调节为与该目标光圈值对应的目标电压值。
其中，上述显示屏的电极电压为上述目标电压值时光线在该显示屏中的透过率与上述目标光圈值对应的光线透过率匹配。
示例性的，上述的光线在该显示屏中的透过率与上述目标光圈值对应的光线透过率匹配是指：上述的光线在该显示屏中的透过率与上述目标光圈值对应的光线透过率相同，或者，上述的光线在该显示屏中的透过率与上述目标光圈值对应的光线透过率间的差值小于或者等于预设阈值。
示例性的，当电子设备对显示屏中的电极施加电压时，显示屏中的液晶分子受到电压作用，使得液晶分子发生扭曲相列的电场效应，从而改变光线的偏转角度，进而实现控制光线在显示屏中的透过率。
示例性的，摄像头的光圈值主要用于调节光线在摄像头中的透过率。一般的，摄像头的光圈值越大，光线在摄像头中的透过率越小，反之，摄像头的光圈值越小，光线在摄像头中的透过率越大。
示例性的，由于摄像头的光圈值主要用于调节光线在摄像头中的透过率，而显示屏中的电极电压的变化也会导致光线在显示屏中的透过率，当电子设备中的摄像头设置在显示屏下方时，由于光线在摄像头中的透过率即等于光线在显示屏中的透过率，因此，电子设备便可通过调整显示屏中的电极电压来达到调节光线在摄像头中的透过率，即达到调节摄像头的光圈值的目的。
示例性的，摄像头的光圈值与显示屏的电极电压值之间呈反比。即当摄像头的光圈值越小，对应的显示屏的电极电压值越大；反之，当摄像头的光圈值越大，对应的显示屏的电极电压值越小。
举例说明，例1：当显示屏的电极电压值为最大值，则光线在液晶分子中的偏转角度正好为90度，此时，光线将全部透过显示屏中的下级偏振片，对应的光圈值为最小值；例2：当摄像头的光圈值为最大值，对应的显示屏的电极电压值为0，此时，光线在显示屏中未发生角度偏转，光线在显示屏中的透过率为0，即无光线透过显示屏中的下级偏振片；例3：当光圈值处于最小值和最大值之间时，对应显示屏的电极电压值处于最大值和最小值之间，光线部分透过显示屏中的下级偏振片。
示例性的，摄像头的光圈值与光线在显示屏中的透过率之间的映射关系可以通过下述的公式1
Figure PCTCN2020105557-appb-000001
来体现。基于上述公式1可知，光线在显示屏中的透过率与摄像头的光圈值的平方成反比。
其中，上述公式1中I为光线在显示屏中的透过率，λ为光圈系数，F为光圈值。例如，若上述的目标光圈值为电子设备自身的固定光圈F min，此时，光线在显示屏中的透过率为100％，即光线全部透过显示屏中的下级偏振片，即，I为100％，
Figure PCTCN2020105557-appb-000002
一般的，随着摄像头的光圈值的逐渐增大，所对应的光线在显示屏中的透过率逐渐减小。
如此，电子设备可以通过确定摄像头的目标光圈值，将显示屏的电极电压调节为与该目标光圈值对应的目标电压值；其中，上述显示屏的电极电压为上述目标电压值时该显示屏的光线透过率与上述目标光圈值对应的光线透过率匹配。这样电子设备便可通过控制显示屏电极电压调节光线的透过率达到可调节光圈的效果，从而解决了由于电子设备中的摄像头采用固定光圈，所导致的可调节光线范围受限的问题。
可选地，在本公开实施例中，电子设备在确定摄像头的目标光圈值时，至少可以通过以下两种实现方式实现。
第一种可能的实现方式中：
示例性的，上述步骤301之前，该方法还包括步骤301a和步骤301b：
步骤301a：电子设备显示拍摄界面。
步骤301b：电子设备接收用户在拍摄界面上的第一输入。
进一步的，结合上述步骤301a和步骤301b，上述步骤301具体包括步骤301c：
步骤301c：响应于上述第一输入，电子设备确定上述摄像头的目标光圈值。
示例性的，上述的第一输入可以包括：用户在拍摄界面上的点击输入，或者，用户在拍摄界面上的滑动输入，或者，用户在拍摄界面上的按压输入，或者，用户在显示屏上的其他可行性输入，具体的可以根据实际使用需求确定，本公开实施例不作限定。

在一种示例中，上述的拍摄界面包括目标调节控件，第一输入为针对上述目标调节控件的第一输入。
在一种示例中，上述的目标调节控件可以以预设透明度叠加显示在拍摄界面中，例如，如果预设透明度记为T1，那么T1的取值范围可以为0％<T1<100％。此外，该目标调节控件还可以高亮度或低亮度显示在拍摄界面上，本公开实施例不作限定。
需要说明的是，上述的目标调节控件的形状可以为圆形、矩形、三角形、菱形、圆环或者多边形等任意可能的形状，也可以直接为具体数值，具体可以根据实际使用需求确定，本公开实施例不作限定。
例1：以目标调节控件为光圈值调节按键“+”和“-”为例，用户通过点击屏幕上显示的按键“+”按预设比例调高摄像头的光圈值，通过点击 按键“-”按预设比例调低摄像头的光圈值。
例2：以目标调节控件为光圈值滚动条为例，该光圈值滚动条上的比例是0-100％，用户可以通过在光圈值滚动条上的滑动输入或点击输入增大或减小调节比例，进而调节摄像头的光圈值。
在第二种可能的实现方式中：
示例性的，上述步骤301包括步骤301d1和步骤301d2：
步骤301d1：电子设备调整摄像头的曝光值。
步骤301d2：若当前曝光值对应的目标亮度与预设亮度匹配，则电子设备将该当前曝光值对应的光圈值，作为目标光圈值。
其中，上述目标亮度为：上述摄像头在上述当前曝光值下拍摄的图片的亮度。
需要说明的是，上述的预设亮度可以为固定值，也可以按照实际应用场景进行灵活调节，本公开实施例对此不作限定。
示例性的，摄像头的曝光值是由：曝光时间、感光度值以及光圈值组成的。
示例性的，可以通过公式2来体现摄像头的曝光值与曝光时间、感光度值以及光圈值之间的关联关系。其中，公式2为：
Figure PCTCN2020105557-appb-000003
EV为曝光值，T为曝光时间，ISO为感光度值，F为光圈值。
示例性的，电子设备在将当前曝光值对应的光圈值，作为目标光圈值时，还可以将当前的曝光时间调节为该当前曝光值对应的曝光时间，以及将当前的曝光时间调节为该当前曝光值对应的感光度值。
示例性的，上述当前曝光值对应的目标亮度与预设亮度匹配可以为：上述当前曝光值对应的目标亮度与上述预设亮度之间的绝对差值大于或等于0，且小于预定阈值。
示例性的，电子设备在确定当前曝光值对应的光圈值时，可以按照第一对应关系表来确定当前曝光值对应的光圈值。其中，上述的第一对应关系表用于表征曝光值分别与曝光参数(即光圈值，或者，曝光时间和感光 度值中的至少一个和光圈值)间的对应关系。
在一种示例中，电子设备以当前曝光值(即当前调节后的曝光值)为索引，在上述的第一对应关系表查找与该当前曝光值对应的光圈值。
在一种示例中，在上述的第一对应关系表中包含：曝光时间、感光度值和光圈值的情况下，上述的第一对应关系表中的曝光值从小到大依次递增，且该第一对应关系表可以拆分为两部分，第一部分中的所有曝光值的曝光时间和感光度值为固定值，光圈值由从大到小逐渐减小，第二部分中的所有曝光值的定光圈值为固定值，曝光时间和感光度值交替从小到大逐渐增大。
示例性的，电子设备在确定当前曝光值对应的目标亮度时：可以基于预配置的第二对应关系表，来确定当前曝光值对应的目标亮度。其中，上述的第二对应关系表用于表征摄像头的曝光值和图像亮度间的对应关系。上述的第二对应关系表中的每个曝光值对应的图像亮度可以为经验值，也可以为电子设备以该曝光值所拍摄的图像的图像亮度(例如，该图像的亮度的平均值)，本公开实施例对此不作限定。
在一种示例中，电子设备调整摄像头的曝光值，并以当前曝光值(即当前调节后的曝光值)为索引，在上述的第二对应关系表查找与该当前曝光值对应的目标亮度，当该目标亮度与预设亮度匹配时，则将该当前曝光值对应的光圈值作为目标光圈值，然后，将显示屏的电极电压调节为该目标光圈值对应的目标电压值，完成光圈值的自动解调，即完成曝光值的自动调节。
示例性的，电子设备在开启自动曝光模式时，确定当前曝光值，将该当前曝光值对应的目标亮度与预设亮度(target)进行比较，若目标亮度大于target，则减小当前曝光值，若目标亮度小于target，则增大当前曝光值，然后，以新设定的曝光值进行拍摄，得到一张图片，计算该图片的亮度平均值，并将该亮度平均值与target进行匹配，若匹配，则完成曝光自动调节，若不匹配，则继续重复上述动作，直到拍摄的图片的亮度平均 值等于target，则完成曝光自动调节。
示例性的，电子设备在开启自动曝光模式时，确定当前曝光值，将该当前曝光值对应的目标亮度与预设亮度(target)进行比较，若目标亮度大于target，则按照第二对应关系表减小当前曝光值，若目标亮度小于target，则按照第二对应关系表增大当前曝光值，然后，以新设定的曝光值进行拍摄，得到一张图片，计算该图片的亮度平均值，并将该亮度平均值与target进行匹配，若匹配，则完成曝光自动调节，若不匹配，则继续重复上述动作，直到拍摄的图片的亮度平均值等于target，则完成曝光自动调节。
可选地，在本公开实施例中，电子设备在调节显示屏中的电极电压时，可以通过调节显示屏的部分区域的电极电压，来降低该电子设备的功耗。
示例性的，上述步骤302包括步骤302a：
步骤302a：电子设备将该显示屏中与摄像头相对应的目标区域的电极电压调节为该目标电压值。
示例性的，上述目标区域为位于摄像头上方的与该摄像头大小对应的区域。
举例说明，以电子设备为手机为例，如图6所示，该手机包括：摄像头(即图6中的50)和显示屏(即图6中的51)，该摄像头位于显示屏顶部，当手机确定到目标光圈值后，手机可以将显示屏51中的目标区域(即图6中的52)的电极电压调节为该目标光圈值对应的目标电压值。如图6所示，该目标区域52为显示屏51中摄像头50所在区域，即显示屏顶部中间区域。
这样，电子设备通过调节该电子设备的显示屏中与摄像头相对应的目标区域的电极电压，将该目标区域的电极电压调节为目标电压值，实现通过控制摄像头对应的显示屏的部分区域的电极电压调节光线的透过率，从而达到只调节摄像头对应的显示屏的目标区域就可以实现可调节光圈的效果。
