具体实施方式
请参照图示，其中相同的组件符号代表相同的组件，本申请的原理是以实施在一适当的运算环境中来举例说明。以下的说明是基于所例示的本申请具体实施例，其不应被视为限制本申请未在此详述的其它具体实施例。
下面先对相关技术进行介绍。
环境光传感器可以感知周围环境的光线情况，包括光线的强度和色度等信息。将环境光传感器置于手机等智能终端中，可以通过检测周围环境光线色度和强度的变化，实现各种智能响应功能。比如在不同的环境下，自动调节显示屏亮度，合理省电同时也可以起到保护用户视力的效果。又比如，在不同的光线条件下，通过感知环境光线的颜色，可以帮助实现更好的拍摄效果。又比如，在一定的条件下，可以在屏幕不解锁的条件下实现某些应用的智能调用。
在非全面屏时代，环境光传感器可以设置在电子设备屏幕的边缘，如图1所示。这样其接受环境光的信息时就能够不受屏幕发光的干扰。或者，环境光传感器也可以设置在电子设备的侧边，如图2所示。但考虑到电子设备的边框多使用金属材料，一般需要进行开孔设计以放置环境光传感器。虽然为了美观，可以将环境光传感器尺寸尽量减小，从而减小屏幕周围的黑边或者电子设备侧边的开孔，但是这终究使电子设备外形不够完美。
在进入全面屏时代后，随着全面屏、瀑布屏甚至环绕屏的流行，屏幕在电子设备表面的占比越来越大，将环境光传感器置于屏幕下方将大大增强电子设备在外形上的竞争力。
将环境光传感器设置在屏幕下方的结构可以如图3所示。环境光进入传感器经过的膜层从上至下为盖板层11，触控层12，偏光片层13，1/4λ玻片层14，OLED显示层15，最后到达环境光传感器16上。其中盖板层、触控层、偏光片层、1/4λ玻片层、OLED显示层中的每一层又包含1—20层的复杂结构，如各种有机层、无机层和OCA胶层等。因此，环境光经过多层的吸收和反射后，真正到达环境光传感器处的光强被大大降低。比如盖板层的透过率为98％，触控层的透过率为95％，偏光片层的透过率为45％，1/4λ玻片层的透过率为95％，OLED显示层透过率为20％，经过这些层后真正到达环境光传感器上的光强度不足环境光的8％。另一方面，显示屏发出的光一部分通过OLED显示层的基底向下发射，到达环境光传感器，另有一部分在向上发射时还会形成反射，到达环境光传感器。
可见，相关技术中，设置在屏下的环境光传感器接收到的光中实际上有很大一部分来自屏幕发出的光。即，相关技术中，设置在屏下的环境光传感器所检测到的环境光强度其实是由两部分组成的，一部分来自屏幕发光，另一部分来自环境光。屏幕发出的光不仅形成了光强度上的背景，同时也形成了光色度上的背景，使得在环境光较弱或屏幕光较强或环境光某一颜色较弱时，实际上环境光传感器检测到的数值会出现很大的背景噪音，即环境光检测的准确度较低。
可以理解的是，本申请实施例的执行主体可以是诸如智能手机或平板电脑等的电子设备。
请参阅图4，图4是本申请实施例提供的环境光检测方法的流程示意图。该环境光检测方法可以应用于电子设备中，该电子设备可以至少包括第一环境光传感器和第二环境光传感器，该第一环境光传感器和该第二环境光传感器被显示屏覆盖，如图5所示，第一环境光传感器17和第二环境光传感器18 均能检测出环境中的红光波段、绿光波段、蓝光波段的强度。

可以理解的是，本申请实施例中，电子设备至少可以配置有第一环境光传感器和第二环境光传感器，该第一环境光传感器和第二环境光传感器均能检测出环境中的红光波段、绿光波段、蓝光波段的强度。基于此，电子设备可以获取当前环境下第一环境光传感器检测到的第一红光强度、第一绿光强度、第一蓝光强度，以及第二环境光传感器检测到的第二红光强度、第二绿光强度、第二蓝光强度。并且，电子设备可以获取红光波段、绿光波段、蓝光波段中的各波段所对应的屏幕光系数和环境光系数。之后，电子设备可以根据第一红光强度、第二红光强度、红光波段对应的屏幕光系数和环境光系数，获取当前环境下来自环境光的红光强度分量；根据第一绿光强度、第二绿光强度、绿光波段对应的屏幕光系数和环境光系数，获取当前环境下来自环境光的绿光强度分量；以及根据第一蓝光强度、第二蓝光强度、蓝光波段对应的屏幕光系数和环境光系数，获取当前环境下来自环境光的蓝光强度分量。之后，电子设备可以根据红光强度分量、绿光强度分量、蓝光强度分量，获取当前环境对应的环境光强度值和/或色温值。由于电子设备可以根据仅受纯环境光影响的红光强度、绿光强度、蓝光强度来计算环境光强度值和/或色温值，因此最终计算得到的环境光强度值和/或色温值排除了屏幕发光的影响，能够真实反映环境光的强度和色温，从而提高了环境光检测的准确度。
请参阅图6，图6为本申请实施例提供的环境光检测方法的另一流程示意图。该环境光检测方法可以应用于电子设备中，该电子设备可以至少包括第一环境光传感器和第二环境光传感器，第一环境光传感器和第二环境光传感器被显示屏覆盖，每一环境光传感器均能检测出环境中的红光波段、绿光波段、蓝光波段、可见光波段以及全波段的光强度。

比如，201、202可以包括：
电子设备可以先获取当前环境的光源类型。
例如，常见的光源包括CWF(Cool White Fluorescent，美国冷白商店光源)、U30(Warm White Fluorescent，美国暖白商店光源)、TL84(欧洲、日本、中国商店光源)、D65(Artificial Daylight，国际标准人工日光)、A(美式厨窗射灯)、Hz光。

在一种实施方式中，电子设备可以通过W/C的比值来识别当前环境的光源类型，其中W为环境光的全波段的光强度，C为环境光中的可见光波段的光强度。由于本申请实施例中的环境光传感器可以检测出环境中的红光波段、绿光波段、蓝光波段、可见光波段以及全波段的光强度，因此电子设备可以先获取所处环境的全波段的光强度W和可见光波段的光强度C，再通过计算W/C的比值来识别当前环境的光源类型。
在一些实施方式中，当W/C的比值位于[0-0.7)的数值区间时，可以识别出所处环境为第一光源类型，即CWF、U30或TL84。当W/C的比值位于[0.7，1.1)的数值区间时，可以识别出所处环境为第二光源类型，即D65。当W/C的比值位于[1.1-1.4)的数值区间时，可以识别出所处环境为第三光源类型，即A。当W/C的比值大于1.4时，可以识别出所处环境为第四光源类型，即Hz。
比如，在识别出当前环境的光源类型后，电子设备可以获取红光波段所对应的屏幕光系数和环境光系数，绿光波段所对应的屏幕光系数和环境光系数，蓝光波段所对应的屏幕光系数和环境光系数。其中，各波段的环境光系数与光源类型对应。即，不同的光源类型下，各波段对应于不同的环境光系数。屏幕光系数可以为电子设备预先处于屏幕点亮且无外界环境光时第一环境光传感器和第二环境光传感器检测到的对应波段的光强比值。环境光系数可以为电子设备预先处于有外界环境光且屏幕熄灭时第一环境光传感器和第二环境光传感器检测到的对应波段的光强比值。

需要说明的是，假设当前环境下第一环境光传感器检测到的环境光强度值B1中来自屏幕发光的光强为x3，来自环境光的光强为y3。那么，x3+y3＝B1。基于屏幕光系数m3和环境光系数n3可知，第二环境光传感器检测到的环境光强度值B2中来自屏幕发光的光强为m3×x3，来自环境光的光强为n3×y3。那么，m3×x3+n3×y3＝B2。可以理解的是，x3+y3＝B1和m3×x3+n3×y3＝B2可以构成二元一次方程组，解这个二元一次方程组，可以得到y3＝(m3×B1-B2)/(m3-n3)。
