以下结合附图对本公开的优选实施例进行详细说明，应当理解，应当
理解，此处所描述的具体实施例仅仅用以解释本公开，并不用于限定本公开。
现在将参考附图描述实现本公开各个实施例涉及的摄像头。在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或“单元”的后缀仅为了有利于本公开的说明，其本身并没有特定的意义。因此，"模块"与"部件"可以混合地使用。
请参阅图1，为摄像头模组的结构框图。摄像头模组包括感光元件11和镜头12。感光元件11和镜头12由一个支架固定在一起，并由软性电路板(Flexible Printed Circuit，FPC)引出引脚与智能终端的中央处理器(CentralProcessing Unit，CPU)相连。实际应用中感光元件可以采用互补金属氧化物半导体(Complementary Metal-Oxide Semiconductor，CMOS)；镜头12可以由多个透镜组成。
研究发现摄像头模组组装后，感光元件的轴平面面和镜头的轴平面之间的角度误差对摄像头模组的感光质量影响很大。请参阅图2a及图2b，为光线射入不同的摄像头模组的示意图。图2a中，摄像头模组的感光元件21的轴平面与镜头22的轴平面之间的夹角α为90°，即感光元件21与镜头22两个器件完全垂直。此时，一束能量均匀的光线23通过透镜垂直进入镜头22。由于在同一透镜上光线衰减相同，因此最终感光元件21上接收到的光量相同，在后期数字处理过程中，由于在感光器件上的光谱损耗相同，可以真实的还原成目前所处的环境。
图2b中，摄像头模组的感光元件21’的轴平面与镜头22’的轴平面之间的夹角α’小于90度，因此当一束能量均匀的光线23’通过透镜进入镜头22’时，在各个透镜上光线衰减会有不同，最终落入感光元件的光量不均匀，导致感光元件上各感光点转化的数字量也存在差异，将会导致后期图像还原时的色彩真实性和算法优化的瓶颈。
基于上述发现，提出本公开方法各个实施例。
请参阅图3，本公开一实施例提出一种摄像头模组感光质量的处理方法，包括：
S310、当摄像头模组表面接收到检测光线时，读取该摄像头模组的感光元件上各感光点转化的数字量；
S320、计算各感光点转化的数字量的差异；
S330、根据该数字量的差异及预设阈值判断该摄像头模组的感光质量是否合格。
具体的，感光元件主要工作原理是利用光电传感器将入射的光信号转换成数字信号，完成转换之后，利用CPU(如电脑)按照一定顺序将感光器件上的数字信号读取并存储起来。实际应用中，步骤310，可以从CPU中读取转化的数字量。
在一个可选的方案中，步骤S310、读取该摄像头模组的感光元件上各感光点转化的数字量之前，该方法还包括：
在全黑实验环境下向该摄像头模组表面垂直发射检测光线，该检测光线为一束能量均匀的光线。
实际应用中，为了将能量均匀的光线垂直射入摄像头模组上，因此该检测需要在全黑实验室环境下进行。发射检测光线时，可以利用专业灯箱将4100K色温的白炽灯能量均匀并且垂直的射入摄像头模组的镜头上，保证射入光线的能量相同和方向一致。
在一个可选的方案中，步骤S320，计算各感光点转化的数字量的差异，包括：
计算该数字量的方差及平均值。
实际应用中，可以利用MATLAB软件进行计算。
在一个可选的方案中，步骤S330，根据该数字量的差异及预设阈值判
断该摄像头模组的感光质量是否合格，包括：
分析该数字量的方差及平均值是否在预设误差范围内；
当该数字量的均匀值和方差在该预设误差范围内时确定该摄像头模组的感光质量合格，否则确定该摄像头模组的感光质量不合格。
实际应用中，在计算得出了所得数据量的分差和均匀性之后，可以利用理论转化得出的误差值和实际检测得的误差值作比较判断，如过实际测得的方差和平均值在理论误差允许的范围内，则说明该摄像头模组的感光质量符合要求。
本实施例的摄像头模组感光质量的处理方法，利用检测光线通过透镜传入感光元件上，通过读取感光元件上光电转换的数字量，计算出所有感光点上得到的数字量差异，从而检测出摄像头模组的感光质量，保证摄像头模组的良率，同时也可以保障摄像头模组对场景的还原能力，排除由于硬件原因导致的手机摄像头对某些场景还原不到位的问题。例如，在步骤S310之前，所述方法还包括：利用检测光线通过透镜传入到所述摄像头模组的感光元件上。透镜可以通过光线发散等，简便形成平行且等能量密度的检测光线。
在上述实施例的基础上，本公开一实施例提供了一种摄像头模组感光质量的处理方法，请参阅图4，方法流程包括：
S410、向摄像头模组垂直发射检测光线。
本实施例中，检测环境为全黑的实验环境，检测光线为一束能量均匀的光线。
S420、读取出每个像素点上将光线转化的数字量，并储存起来。
S430、将读取的数字量输入MATLAB软件计算出该数字量的平均值、方差及走势，并根据计算出的方差及走势绘制出仿真图。
实际应用中，在执行本步骤的时候也可以利用光电转化器转换公式将
得到的数字量转换成RGB分量，并画图显示出来，这样能够更加直观地看出所得的数字量的均匀性。
S440、将计算的平均值及方差与预设的阈值进行比较判断该摄像头模组的感光质量是否符合要求，若符合要求则执行步骤S460，否则执行S450。
实际应用中，计算出数据量的分差和均匀性之后，可以利用理论转化得出的误差值和实际测得的误差值作比较，如实际测得的方差和均匀值在理论误差允许范围内，则说明该摄像头模组的感光质量符合要求，可以进行后期工作，否则其感光质量就不合格。
S450、根据该仿真图分析该摄像头模组的镜头的轴平面面的转动方向，从而使得在对该摄像头模组校正时将该镜头的轴平面向转化数字量低的感光点所在的方向转动，并执行步骤S410。
该步骤主要是对问题模组的一个校正过程。实际应用中，可以利用MATLAB软件分析出问题模组差异主要存在哪些部分，然后根据分析结果调整镜头方向减少差异。
在步骤S430中得出了该摄像头模组数字量的方差和平均值，并绘制图仿真图，根据仿真图可以清楚地分析出摄像头模组哪部分转化数字量高，按照反向思维将镜头轴面向数字量低的方向转动，之后反复进行步骤S410至S450，直到摄像头模组符合要求。
实际应用中，在检测过程中，当确定某个摄像头模组的感光质量不符合要求时，可以向检测者发出警报。通过警报的发出，可以提示检测者检测到不符合要求的摄像头模组。
在一些实施例中，所述方法还可包括：当所述摄像头模组的感光质量不合格时，向与所述处理装置通信的显示装置，发送校正所述摄像头模组的轴平面的转动方向的提示。比如，发出提示音和/或直接在与处理装置通讯的显示装置上向检测者提示需要对摄像头模组进行校正以及镜头的轴平
面向的转动方向。
S460、确认摄像头模组感光质量合格。
本实施例的摄像头模组感光质量的处理方法，利用检测光线通过透镜传入感光元件上，通过读取感光元件上光电转换的数字量，计算出所有感光点上得到的数字量差异，从而检测出摄像头模组的感光质量，保证摄像头模组的良率，同时也可以保障摄像头模组对场景的还原能力，排除由于硬件原因导致的手机摄像头对某些场景还原不到位的问题，并且能够在检测出摄像头模组的感光质量不合格时，分析出问题模组差异主要存在哪些部分，并根据分析结果对问题模组进行校正。
