摄像头控制方法、装置以及屏下摄像头结构 技术领域
本发明实施例涉及智能终端领域，具体而言，涉及一种摄像头控制方法、装置以及屏下摄像头结构。
背景技术
全面屏从字面上解释就是手机的正面全部都是屏幕，手机的四个边框位置都是采用无边框设计，追求接近100％的屏占比。但实际上受限于目前的技术，暂时只是超高屏占比的手机，没有能做到手机正面屏占比100％的手机。现在大家所说的全面屏手机是指屏占比可以达到90％以上，拥有超窄边框设计的手机。
所有全面屏手机厂商都必须直面并解决共同的问题：听筒、前摄像头和各种传感器必须要放置在手机正面，这是用户的日常需求，但这些器件放置在手机正面又必然会占据一部分显示面积。目前各大手机厂商都在想办法压缩这些功能器件所占的面积，于是相继推出了各自的全面屏手机，“刘海屏”、“水滴屏”、“挖孔屏”等各种全面屏方案层出不穷。
相关技术中提出屏下摄像头，包括：显示面板、背光模块、导光部件及光源部件。所述背光模块设置于所述显示面板的一侧，且在与屏下摄像头对应位置设有第一开孔。所述导光部件插装在所述第一开孔中，用于将进入所述导光部件中的光束导向所述第一开孔对应的显示面板区域。所述光源部件用于为所述导光部件提供光源。当所述屏下摄像头启动时，所述光源部件关闭，当所述屏下摄像头不启动时，所述光源部件开启或关闭，故能够使所述显示面板上的通孔或盲孔重新具有显示能力，且依旧维持所述屏下摄像头所能获取的影像质量。
通过侧面导光部件提供光源，无法对光线方向进行调整聚集，大部分光线无法向上射入玻璃区域，影响背光效率。同时，无法在前摄像头使用时，提供补偿光线。
相关技术中屏下摄像头进光有限导致在环境光较弱时拍摄效果不佳的问题。

本实施例中还提供了一种显示屏下摄像头结构，图3是根据本申请实施例的屏下摄像头结构的示意图，如图3所示，包括：显示屏1和设置于所述显示屏下的摄像头2，所述显示屏1包括显示玻璃11和显示区背光12，其中，在所述摄像头2上方的所述显示区背光设置开孔区域，所述显示玻璃11在所述开孔区域凸向所述摄像头2方向形成凸面玻璃13，在所述凸面玻璃13与所述摄像头22之间连接有一个呈环形圆锥结构的柔性电路板3以围成所述摄像头2的视角，在所述柔性电路板3上从所述摄像头2端至所述凸面玻璃端依次排列有多个灯珠，其中，
在所述摄像头2处于开启状态下，所述多个灯珠中靠近所述摄像头2端的灯珠处于关闭状态，远离所述摄像头2的灯珠处于点亮状态，远离所述摄像头2的灯珠发出的光通过所述凸面玻璃13折射后在所述凸面玻璃13上形成光环，使得所述凸面玻璃13处于画面不显示状态；
在所述摄像头2处于关闭状态下，所述多个灯珠均处于点亮状态，通过所述凸面玻璃13折射后为所述凸面玻璃13提供背光，使得所述凸面玻璃13处于画面显示状态。
在一个示例性实施例中，远离所述摄像头2的灯珠处于亮度最大值。
在一个示例性实施例中，所述柔性电路板3的环形圆锥结构的角度是根据所述摄像头2的视角、所述摄像头2的像素、所述显示屏的亮度、所述显示区背光的厚度，所述开孔区域 的大小确定的。
在另一个示例性实施例中，所述柔性电路板3，用于导通所述多个灯珠，且与背光芯片连接，其中，所述背光芯片，用于控制所述多个灯珠的亮度。
本实施例中，显示玻璃11分为正常显示区的平面玻璃12和前摄区的凸面玻璃13；前摄像头2的进光角度为视角301；正常显示区背光12可以使用现有背光结构方案，不再详细叙述；前摄区背光4分为多个小的LED灯珠和柔性电路板3，柔性电路板3将多个LED灯珠连接导通，并能通过背光芯片独立控制每一个灯珠的亮度大小，前摄区背光4整体呈现环形圆锥结构，中心开孔避让前摄像头2的视角。
图4是根据本申请优选实施例的屏下摄像头结构的示意图一，如图4所示，当不使用前摄像头，且需要全屏显示时，LED灯珠发光为前摄区显示玻璃提供背光。每一个LED灯珠都有一定的照射角度，能完整覆盖整个前摄区显示玻璃，且通过背光芯片对每一个LED灯珠亮度的调节，能够使整个前摄区显示玻璃背光均匀，而不需要另外添加散光或导光材料。LED灯珠发出的光线经过前摄区的凸面玻璃13的会聚作用，会集中向上射出屏幕，达到更好的显示效果。
图5是根据本申请优选实施例的屏下摄像头结构的示意图二，如图5所示，当需要使用前摄像头时，如果LED灯珠的全部灯珠仍然都亮的话，靠近前摄像头的LED灯珠所发射的光线，有一部分会经过凸面玻璃13的反射进入前摄像头视角，干扰前摄像头成像。
图6是根据本申请优选实施例的屏下摄像头结构的示意图三，如图6所示，使用前摄像头时，LED灯珠只打开远离前摄像头的一部分，保证LED灯珠发射的光线不会经过反射进入前摄像头视角，且打开的LED灯珠调整到最大亮度，此时的凸面玻璃13不显示画面，而是形成一个光环。使用前摄像头拍摄的大多是近距离的人物和景物，光环射出的光线照射到近距离的人物和景物上，再反射回来，可以增大前摄像头2的进光量，改善成像效果。
图7是根据本申请优选实施例的屏下摄像头结构的示意图四，如图7所示，在打开前摄像头时，哪些LED灯珠可以点亮，需要通过3D模拟计算与暗箱调试相结合的方式。主要与以下因素有关，包括：柔性电路板的倾斜角度a、凸面玻璃的弧度b、LED灯珠的发光角c、前摄像头的进光角d、灯珠发射的光线经过凸面玻璃反射后的光线角度e、背光开孔边缘到前摄像头中心的横向距离f、灯珠到柔性电路板边缘的距离g、灯珠到前摄像头中心的横向距离h。
进行3D模拟计算时，最主要的两个因素是灯珠发射的光线经过凸面玻璃反射后的光线角度e和灯珠到前摄像头中心的横向距离h。光线角度e越小，光线越不容易进入前摄像头、灯珠到前摄像头中心的横向距离h越大，光线越不容易进入前摄像头。
根据图7标注的各尺寸之间关系可以计算得出：e＝90°-a+(c/2)-2b，h＝f-g*sin(a)。由计算公式可以得知，在一定程度内，角度a和角度b越大，角度e就越小；角度c越小，角度e就越小。在一定程度内，距离f越大，距离h就越大；距离g和角度a越小，距离h就越大。具体各个尺寸和角度设计时还要综合考虑，避免柔性电路板对前摄像头视角的遮挡，以及背光开孔过大导致露出前摄像头边缘等问题。
实际应用时先经过3D模拟计算，得出初步的LED灯珠设计方案，要最终确认使用前摄像头时哪些LED灯珠可以打开，需要在暗箱中进行详细调试，将整机放入暗箱中，打开3D模拟 计算得出的可以点亮的一部分灯珠，同时打开前摄像头，如果前摄像头的感光器件能够感应到光线则需要再关闭靠近前摄像头的一排灯珠，直到前摄像头的感光器件无法感应到LED灯珠反射的光线为止。
图8是根据本申请优选实施例的屏下摄像头结构的示意图五，如图8所示，凸面玻璃13会聚作用，也会使原本无法照射入前摄视角的环境光线经过会聚，射入前摄视角，增大了前摄像头进光量，有利于进一步改善成像效果。
在本实施例中还提供了一种摄像头控制装置，该装置用于实现上述实施例及优选实施方式，已经进行过说明的不再赘述。如以下所使用的，术语“模块”可以实现预定功能的软件和/或硬件的组合。尽管以下实施例所描述的装置较佳地以软件来实现，但是硬件，或者软件和硬件的组合的实现也是可能并被构想的。
