技术领域
本申请涉及摄像模组技术领域，尤其涉及一种摄像模组、终端设备、成像方法及成像装置。
背景技术
随着科技的发展，电子设备上集成了越来越多的功能，如拍照功能。而且随着电子设备的广泛使用，用户对拍照功能的要求越来越高，比如，用户需要更高质量的图像，更高的光学变焦倍数等。目前，为了实现更高的光学变焦倍数，设置在电子设备上的摄像模组的结构如图1或图2所示。对于图1所示的结构，采用直立式架构，在聚焦时是通过马达驱动整个光学镜头组件来实现的，用于成像的光路较短，造成摄像模组无法实现较大的光学变焦倍数。对于图2所示的结构，也是通过马达驱动成像镜头组件来进行聚焦，需要较长的成像光路，造成摄像模组的尺寸也比较大，由于电子设备空间有限，也无法实现较大的光学变焦倍数。
发明内容
本申请提供一种摄像模组、终端设备、成像方法及成像装置，用于在小尺寸的摄像模组中，实现较大的光学变焦倍数。
第一方面，本申请提供一种摄像模组，该摄像模组可包括第一驱动组件、光学镜头组件、光线调整组件和图像传感器，光线调整组件和图像传感器沿光学镜头组件的主光轴的方向依次设置；光学镜头组件用于接收来自被摄物体的光线；光线调整组件用于对光学镜头组件传播过来的光线进行光路折叠；第一驱动组件用于驱动光线调整组件移动，使得光路折叠后的光线聚焦至图像传感器；图像传感器用于根据聚焦后的光线成像。
基于该方案，通过光线调整组件对光学镜头组件传播过来的光线进行光路折叠，有助于缩短成像光路。在光学镜头组件的物理焦距一定的情况下，通过光线调整组件对光路折叠，既可以实现像距满足成像条件，又可以减小成像光路，从而可缩短摄像模组的尺寸。也可以理解为，当摄像模组处于有限的空间(或者摄像模组的尺寸有限)时，采用本申请的摄像模组可采用较大物理焦距的光学镜头组件，从而可实现较大的光学变焦倍数。
本申请中，光线调整组件包括M个第一反射面和M个第二反射面，M个第一反射面与M个第二反射面一一相对设置；M个第一反射面依次相接、且任意相邻两个第一反射 面之间的夹角为θ 1，θ 1大于0度且小于180度；M个第二反射面依次相接、且任意相邻两个第二反射面之间的夹角为θ 2，θ 2大于0度且小于180度，M为大于或等于2的整数；其中，与光学镜头组件最邻近的第一反射面用于接收和反射来自光学镜头组件的光线；与图像传感器最邻近的第一反射面用于将光路折叠后的光线反射至图像传感器。
经光学镜头组件传播过来的光线在光线调整组件中的光路为：与光学镜头组件最邻近的第一反射面接收来自光学镜头组件的光线，并将接收到的光线反射至与其(即与光学镜头组件最邻近的第一反射面)相对设置的第二反射面；第二反射面将接收到的光线反射至与其(即第二反射面)依次相接的最近邻的第二反射面；该最近邻的第二反射面将接收到的光线反射至与其(最近邻的第二反射面)相对设置的第一反射面，依次反射，直至将光线反射至与图像传感器最近邻的第一反射面，与图像传感器最邻近的第一反射面接收到的光线为光路折叠后的光线，且光路折叠后的光线的传播方向沿主光轴的方向，与图像传感器最邻近的第一反射面将接收到的光路折叠后的光线反射至图像传感器。
基于上述光线调整组件，可对光学镜头组件传播过来的光线进行2M次光路折叠。
在一种可能的实现方式中，上述θ 1大于或等于60度且小于或等于120度，即60°≤θ 1≤120°；θ 2大于或等于60度且小于或等于120度，即60°≤θ 2≤120°。示例性地，θ 1可以为30度、45度、60度、90度、120度、135度、或150度；θ 2可以为30度、45度、60度、90度、120度、135度、或150度。
在一种可能的实现方式中，M个第一反射面形成的层状结构与M个第二反射面形成的层状结构互不重叠。示例性地，M个第一反射面位于第一层，M个第二反射面位于第二层，第一层与第二层互不重叠。
通过将M个第一反射面和M个第二反射面设置在互不重叠的两层，可以对光学镜头组件传播过来的光线在互不重叠两层之间进行光路折叠。
在一种可能的实现方式中，第i第一反射面与第i第二反射面平行，其中，第i第一反射面与第i第二反射面相对设置，第i第一反射面为M个第一反射面中的一个，第i第二反射面为M个第二反射面中的一个。
通过将第i第一反射面与第i第二反射面平行设置，可方便摄像模组的组装。若第一反射面与相对设置的第二反射面不平行，在摄像模组水平放置拍摄图像时，图像传感器上形成的图像可能会出现一定的倾斜。
在一种可能的实现方式中，M个第一反射面可包括：M/2个依次相接的L型反射镜的反射面，其中，任意一个L型反射镜包括两个反射面；或M个依次相接的反射镜的反射面；或M/2个依次相接的直角棱镜的反射面；或依次相接的P个反射镜和Q个直角棱镜的反射面，其中，任意一个直角棱镜包括两个反射面，P+2Q＝M，P和Q均为正整数；或依次相接的m个反射镜和n个L型反射镜的反射面，其中，m+2n＝M，m和n均为正整数；或依次相接的p个直角棱镜和q个L型反射镜的反射面，其中，2p+2q＝M，p和q均为正整数；或依次相接的k个直角棱镜、t个L型反射镜和h个反射镜的反射面，其中，2k+2t+h＝M，k、t和h均为正整数。
在一种可能的实现方式中，M个第二反射面包括：M/2个依次相接的L型反射镜的反射面，其中，任意一个L型反射镜包括两个反射面；或M个依次相接的反射镜的反射面；或M/2个依次相接的直角棱镜的反射面；或依次相接的K个反射镜和L个直角棱镜的反射面，其中，任意一个直角棱镜包括两个反射面，K+2L＝M，K和L均为正整数；或依次 相接的u个反射镜和v个L型反射镜的反射面，其中，u+2v＝M，u和v均为正整数；或依次相接的l个直角棱镜和s个L型反射镜的反射面，其中，2l+2s＝M，l和s均为正整数；或依次相接的j个直角棱镜、w个L型反射镜和z个反射镜的反射面，其中，2j+2w+z＝M，j、w和z均为正整数。
当M＝2时，两个第一反射面为一个L型反射镜的两个互相垂直的反射面，两个第二反射面为一个直角棱镜的两个互相垂直的反射面。
进一步，可选地，L型反射镜的两个反射面相互垂直。
在一种可能的实现方式中，L型反射镜的两个反射面的长度在主光轴的方向的投影不相同。其中，L型反射镜的两个反射面中，一个反射面靠近光学镜头组件且远离图像传感器；另一个面远离光学镜头组件且靠近图像传感器。
在一种可能的实现方式中，靠近光学镜头组件且远离图像传感器的一面的长度大于远离光学镜头组件且靠近图像传感器的一面的长度；或者，靠近光学镜头组件且远离图像传感器的一面的长度小于远离光学镜头组件且靠近图像传感器的一面的长度；或者，靠近光学镜头组件且远离图像传感器的一面的长度等于远离光学镜头组件且靠近图像传感器的一面的长度。
在一种可能的实现方式中，第一驱动组件具体用于驱动M个第一反射面沿第一方向移动，和/或，驱动M个第二反射面沿第二方向移动；其中，第一方向与第二方向相反，且第一方向和第二方向均为垂直于主光轴的方向。
通过第一驱动组件驱动M个第一反射面沿第一方向移动，和/或，驱动M个第二反射面沿第二方向移动，可以实现对不同物距下的光线聚焦，从而可保证图像传感器上形成清晰的图像。而且，第一驱动组件通过驱动光线调整组件的M个第一反射面和/或M个第二反射面移动实现聚焦，不需要移动光学镜头组件，从而光学镜头组件也不需要与第一驱动组件耦合。
在一种可能的实现方式中，第一驱动组件具体用于驱动M个第一反射面沿垂直于主光轴的方向移动。

具体实施方式
为了使本申请的目的、技术方案和优点更加清楚，下面将结合附图对本申请作进一步地详细描述。
下面，对本申请中的部分用语进行通用解释说明，以便于本领域技术人员理解，并不对本申请中的用语进行限定。
一、焦距：焦距的大小标志着折光能力的大小，焦距越短，其折光能力就越大。光学镜头组件的焦距决定了该光学镜头组件拍摄的被摄物体在成像平面上所生成图像的大小。假设以相同的距离面对同一被摄物体进行拍摄，那么光学镜头组件的焦距越长，则被摄体在感光元件(charge-coupled device，CCD)上所生成的图像的放大倍率就越大。
二、等效焦距：将不同尺寸感光元件上成像的视角，转化为135摄像模组上同样成像视角所对应的光学镜头组件焦距，这个转化后的焦距即是135等效焦距，也就是等效焦距。也可以理解为，135摄像模组作为一种标准，把非135规格摄像模组的焦距折算成135摄像模组的焦距。可选地，等效焦距＝光学镜头组件的物理焦距*焦距系数(或焦距倍数)，其中，焦距系数为非135规格的摄像模组的感应元件对角线长度与135规格摄像模组的感光元件的聚焦线长度的比值。例如，光学镜头组件的物理焦距＝31mm，非135规格的摄像模组的感应元件对角线长度为4.8mm，135规格摄像模组的感光元件的对角线长度为43.27mm，则等效焦距＝31*43.27/4.8≈280mm。
三、光学变焦：主要是摄像模组内不同焦距的对比比例和切换。可用光学变焦倍数表示光学变焦的能力，光学变焦倍数越大，能拍摄的景物就越远。光学变焦倍数的大小与光学镜头组件的物理焦距相关。常以摄像模组的等效焦距为28mm对应1X(即1倍)光学变焦倍数。比如，135规格摄像模组的感光元件的对角线长度为43.27mm，若非135规格的摄像模组的感应元件对角线长度为4.8mm，光学镜头组件的物理焦距＝31mm，则等效焦距＝31*43.27/4.8≈280mm；则该摄像模组的光学变焦倍数＝280/28＝10X。再比如，若非135规格的摄像模组的感应元件对角线长度为4.8mm，光学镜头组件的物理焦距＝20mm，则等效焦距＝20*43.27/4.8≈180mm，则该摄像模组的光学变焦倍数＝180/28≈6.4X。
四、聚焦：聚焦也称为对光或对焦。通过摄像模组中的具有改变焦距的组件以变动像距，使被摄物体成像清晰的过程。聚焦包括自动聚焦和手动聚焦，其中，自动聚焦(auto focus)是利用物体光反射的原理，将反射的光被摄像模组上的感光元件接受，通过计算机处理，驱动驱动组件进行聚焦的方式。例如，摄像模组发射一种红外线(或其它射线)，根据被摄体的反射确定被摄体的距离，然后根据测得的结果调整像距，实现自动聚焦。
五、光学防抖：也称为光线抖动补偿，是指在摄像模组中，通过对光学镜头组件的移动或其它组件的移动，抵消由于抖动引起的成像光线偏移，使光路保持稳定，从而有效的克服因摄像模组的抖动产生的图像模糊。
如背景技术所描述的，目前摄像模组的结构如图1或图2，摄像模组是通过驱动成像 镜头的移动来实现对焦，需要较长的成像光路，从而造成摄像模组的尺寸比较大。
鉴于上述问题，本申请提出一种摄像模组，该摄像模组可通过光线调整组件对光学镜头组件传播过来的光线进行光路折叠，有助于减小成像光路占用的空间长度，从而有助于减小摄像模组的尺寸。
下面结合附图3至附图9，对本申请提出的摄像模组进行具体阐述。
如图3所示，为本申请提供的一种摄像模组的结构示意图。该摄像模组可包括光学镜头组件101、第一驱动组件102、光线调整组件103和图像传感器104，其中，光线调整组件103和图像传感器104沿光学镜头组件的主光轴的方向依次设置。光学镜头组件用于接收来自被摄物体的光线；光线调整组件用于对光学镜头组件传播过来的光线进行光路折叠；第一驱动组件用于驱动光线调整组件移动，使得光路折叠后的光线聚焦至图像传感器；图像传感器用于根据聚焦后的光线成像。
基于上述摄像模组，通过光线调整组件对光学镜头组件传播过来的光线进行光路折叠，有助于缩短成像光路。在光学镜头组件的物理焦距一定的情况下，通过光线调整组件对光路折叠，既可以实现像距满足成像条件，又可以减小成像光路，从而可缩短摄像模组的尺寸。也可以理解为，当摄像模组处于有限的空间时，采用本申请的摄像模组可采用较大物理焦距的光学镜头组件，从而可实现较大的光学变焦倍数。进一步，本申请是通过第一驱动组件驱动光线调整组件移动，以实现对折叠后的光线聚焦，不需要移动光学镜头组件。也就是说，光学镜头组件不需要与第一驱动组件耦合。
需要说明的是，被摄物体包括但不限于单一的物体，例如，拍摄人时，被摄物体包括人及人周围的景物，即人周围的景物也为被摄物体的一部分。也可以理解为，光学镜头组件的视场角范围内的物体均可称为被摄物体。
在一种可能的实现方式中，光线调整组件和图像传感器沿主光轴的方向依次设置是指：光线调整组件和图像传感器均过主光轴。例如，主光轴可以经过光线调整组件的中间区域，或者主光轴经过光线调整组件偏上的区域，或者主光轴经过光线调整组件偏下的区域。主光轴可以经过图像传感器的中间区域，或者主光轴经过图像传感器偏上的区域，或者主光轴经过图像传感器偏下的区域。
在一种可能的实现方式中，主光轴的方向可以是双向的，也可以是单向的(可参见上述图3)。
下面对图3所示的各个功能组件分别进行介绍说明，以给出示例性的具体实现方案。为方便说明，下文中的光学镜头组件，第一驱动组件、光线调整组件和图像传感器均未加标识。
一、光学镜头组件
作为示例，图4a给出了一种光学镜头组件的结构示意图。该光学镜头组件包括第一透镜401和第二透镜402。其中，第一透镜401为平凸透镜、第二透镜402为凸凹透镜，凸凹透镜是指中央部分比边缘部分薄的透镜。第一透镜401相较于第二透镜402靠近被摄物体，远离图像传感器。第二透镜402相较于第一透镜401靠近图像传感器，远离被摄物体。
作为又一个示例，图4b给出了另一种光学镜头组件的结构示意图。该光学镜头组件包括第一透镜401、第二透镜402和第三透镜402，第三透镜403位于第一透镜401和第 二透镜402之间。其中，第一透镜401为平凸透镜、第二透镜402为凸凹透镜、第三透镜403为双凸透镜。第一透镜401相较于第二透镜402和第三透镜403靠近被摄物体，远离图像传感器。第二透镜402相较于第一透镜401和第三透镜403靠近图像传感器，远离被摄物体。应理解，图4a或图4b所示的光学镜头组件的结构仅是一个示例，本申请中的光学镜头组件可以具有比图4b更多的透镜，例如可以包括3个以上的透镜。其中，透镜可以是双凸透镜，平凸透镜或者凸凹透镜中的任一种，本申请对此不做限定。
主光轴也可称为主轴，是指通过透镜的两个球面球心的直线，如图4a所示，通过第一透镜401和第二透镜402的球面球心的直线，称为主光轴。如图4b所示，通过第一透镜401、第二透镜402和第三透镜403的球面球心的直线，称为主光轴。
在一种可能的实现方式中，为了抑制温漂，光学镜头组件中至少有一个透镜的材料是玻璃。也可以理解为，光学镜头组件中的透镜不能全是塑胶镜片。
进一步，可选地，为了尽量减小摄像模组的高度(与终端设备厚度方向一致)，光学镜头组件中的透镜(或称为镜片)在摄像模组的高度方向(可参见上述图4a或图4b)上可做切割，如I-cut方式。
二、光线调整组件
本申请中，光线调整组件可包括M个第一反射面和M个第二反射面，M个第一反射面与M个第二反射面一一相对设置，即一个第一反射面对应一个相对设置的第二反射面，M个第一反射面依次相接、且任意相邻两个第一反射面之间的夹角为θ 1，θ 1大于0度且小于180度；M个第二反射面依次相接、且任意相邻两个第二反射面之间的夹角为θ 2，θ 2大于0度且小于180度，M为大于或等于2的整数。进一步，可选地，M个第一反射面中与光学镜头组件最邻近的第一反射面用于接收和反射来自光学镜头组件的光线，M个第一反射面中与图像传感器最邻近的第一反射面用于将光路折叠后的光线反射至图像传感器。应理解，相邻两个第一反射面之间的夹角θ 1是指相邻两个第一反射面相交形成的最小角度，相邻两个第二反射面之间的夹角θ 2是指相邻两个第二反射面相交形成的最小角度。
在一种可能的实现方式中，上述θ 1大于或等于60度且小于或等于120度，即60°≤θ 1≤120°；θ 2大于或等于60度且小于或等于120度，即60°≤θ 2≤120°。示例性地，θ 1可以为30度、45度、60度、90度、120度、135度、或150度；θ 2可以为30度、45度、60度、90度、120度、135度、或150度。
参阅图5a，为本申请提供的一种光线调整组件的结构示意图。该光线调整组件以M＝2为例说明。该光线调整组件包括两个第一反射面(即第一反射面a和第一反射面b)和两个第二反射面(即第二反射面A和第二反射面B)。其中，第一反射面a和第一反射面b依次相接，且第一反射面a和第一反射面b之间的夹角为大于0度且小于180度的θ 1。第二反射面A和第二反射面B依次相接，且第二反射面A和第二反射面B之间的夹角为大于0度且小于180度的θ 2。第一反射面a与第二反射面A相对设置，第一反射面b与第二反射面B相对设置。第一反射面a为与光学镜头组件最邻近的第一反射面，第一反射面a用于接收来自光学镜头组件的光线，并将光学镜头组件的传播过来的光线反射至第二反射面A；第一反射面b为与图像传感器最邻近的第一反射面，第一反射面b用于将光路折叠后的光线反射至图像传感器。
本申请中，摄像模组采用上述图5a所示的光线调整组件的结构时，可以采用物理焦距 不小于20mm的光学镜头组件，对应的等效焦距不小于180mm，摄像模组的光学变焦倍数不小于6倍。由此可见，通过对光学镜头组件传播过来的光线进行光路折叠，可以使得摄像模组实现较大的光学变焦倍数，例如，6倍、8倍或10倍等。进一步，可以实现摄像模组的高度不大于9mm，长度不大于40mm，以方便的集成到终端设备中。
需要说明的是，M个第一反射面的长度在平行于主光轴的方向上的投影可以相等，也可以不相等。在一种可能的实现方式中，平行于主光轴的方向与主光轴的方向可以是相同的。如图5b所示，为本申请提供的一种光线调整组件的正视图。该图5b中以两个第一反射面为例，分别为第一反射面a和第一反射面b。第一反射面a的长度为L a，第一反射面b的长度为L b，第一反射面A的长度L a在平行于主光轴的方向上的投影为L aa，第一反射面b的长度L b在平行于主光轴的方向上的投影为L bb，L aa与L bb可以相等，也可以不相等。即，L aa大于L bb；或者L aa小于L bb；或者L aa等于L bb。应理解，第二反射面A的长度为L A，第二反射面B的长度为L B，第二反射面A的长度L A在平行于主光轴的方向上的投影为L AA，第二反射面B的长度L B在平行于主光轴的方向上的投影为L BB，L AA与L BB可以相等，也可以不相等。即，L AA大于L BB；或者L AA小于L BB；或者L AA等于L BB。
在一种可能的实现方式中，M个第一反射面形成的层状结构与M个第二反射面形成的层状结构互不重叠。示例性地，M个第一反射面位于第一层，M个第二反射面位于第二层，其中，第一层和第二层互不重叠。进一步，可选地，第一层位于第二层的上层。
结合上述图5a，第一反射面a和第一反射面b形成第一层，第二反射面A和第二反射面B形成第二层。第一反射面a用于接收来自光学镜头组件传播过来的光线，并将接收到的光线反射至第二反射面A，第二反射面A用于将接收到的光线反射至第二反射面B，第二反射面B用于将接收到的光线反射至第一反射面b，第一反射面b用于将光路折叠后的光线反射至图像传感器。也就是说，经光学镜头组件传播过来的光线在光线调整组件中的光路为：经第一反射面a反射至第二反射面A，再经第二反射面A反射至第二反射面B，再经第二反射面B反射至第一反射面b，经第一反射面b反射至图像传感器。即来自光学镜头组件传播过来的光线在光线调整组件中经过四次弯折。如此，实现了对光学镜头组件传播过来的光线进行光路折叠，从而有助于缩短摄像模组的长度，其中，摄像模组的长度方向垂直于摄像模组的高度方向(参见图4a或图4b)。
本申请中，第i第一反射面可与第i第二反射面平行，第i第一反射面与第i第二反射面相对设置，第i第一反射面为M个第一反射面中的一个，第i第二反射面为M个第二反射面中的一个。通过将第i第一反射面与第i第二反射面平行设置，可方便摄像模组的组装。可以理解的是，若第一反射面与相对设置的第二反射面不平行，在摄像模组水平放置拍摄图像时，图像传感器上形成的图像可能会出现一定的倾斜。
结合上述图5a，第i第一反射面可以为第一反射面a或第一反射面b，第i第二反射面为第二反射面A或第二反射面B。若第i第一反射面为第一反射面a，则第i第二反射面为第二反射面A，第一反射面a与第二反射面A平行，且第一反射面a与第二反射面A相对设置；若第i第一反射面为第一反射面b，则第i第二反射面为第二反射面B，第一反射面b与第二反射面B平行，且第一反射面b与第二反射面B相对设置。
结合上述图5a，第i第一反射面与第i第二反射面平行包括：第一反射面a与第二反射面A平行，且第一反射面b与第二反射面B平行；或者，第一反射面a与第二反射面A 平行，且第一反射面b与第二反射面B不平行；或者，第一反射面a与第二反射面A不平行，且第一反射面b与第二反射面B平行。应理解，若第一反射面a与第二反射面A平行且第一反射面b与第二反射面B平行，则θ 1与θ 2相等。

在一种可能的实现方式中，θ 4大于或等于30度且小于或等于60度，即30°≤θ 4≤60°，θ 5大于或等于30度且小于或等于60度，即30°≤θ 5≤60°。示例性地，θ 4可为30度、45度、或60度；θ 5可为30度、45度、或60度。
需要说明的是，图5c所示的第一反射面c可参见上述第一反射面a或第一反射面b的介绍，第二反射面C可参见上述第二反射面A或第二反射面B的介绍，第一反射面c和第二反射面C之间的位置关系可参见上述第一反射面a和第二反射面A之间的位置关系，或者也可参见上述第一反射面b和第二反射面B的介绍，此处不再一一赘述。也就是说，第一反射面c和第二反射面C可理解为图5a中的第一反射面a和第二反射面A，或者可理解为图5a中的第一反射面b和第二反射面B。
本申请中，M个第一反射面可以为M/2个依次相接的L型反射镜的两个反射面。L型反射镜的反射面可以理解为在L型器件的两个相互垂直的面上涂覆有反射膜，形成L型反射镜的两个反射面。需要说明的是，L型反射镜为一体式结构。
如图6a所示，为本申请提供的一种L型反射镜的正视图。该L型反射镜的两个反射面互相垂直，即θ 1＝90°。其中，L型反射镜的两个反射面分别为反射面a和反射面b，反射面a和反射面b均为第一反射面。应理解，反射面a和反射面b可为L型反射镜的一侧的两个外表面。结合图6b，反射面a的长度为H a，宽度为K a，厚度为L a；反射面b的长度为H b，宽度为K b，厚度为L b。进一步，可选地，L型反射镜的两个反射面的长度可以相等，也可以不相等。也就是说，H a可以等于H b；或者H a可以大于H b；或者H a可以小于H b，图6a仅是以H a大于H b示例的。在一种可能的实现方式中，较长的反射面的长度的取值范围可以为[7mm，12mm]，较短的反射面的长度取值范围可为[4mm，8mm]。结合上述图6a，即H a的取值范围可为[7mm，12mm]，H b的取值范围可为[4mm，8mm]。
进一步，可选地，L型反射镜的两个反射面的宽度可以相等，也可以不相等；结合上述图6a和图6b，反射面a的宽度可以与反射面b的宽度相等，也可以不相等。即，K a可以等于K b；或者K a可以大于K b；或者K a可以小于K b。在一种可能的实现方式中，L型反射镜的两个反射面的宽度的取值范围可为[3mm，10mm]。
进一步，可选地，L型反射镜的两个反射面的厚度可以相等，也可以不相等；结合上述图6a和图6b，反射面a的厚度可以与反射面b的厚度相等，也可以不相等。即，L a可 以等于L b；或者L a可以大于L b；或者L a可以小于L b。在一种可能的实现方式中，L型反射镜的两个反射面的厚度的取值范围可为[0.8mm，4mm]。
应理解，上述图6a中的反射面a相较于反射面b更靠近光学镜头组件，远离图像传感器；反射面b相较于反射面a更靠近图像传感器，远离光学镜头组件。图6b可以是图6a所示的L型反射镜的三维图。需要说明的是，靠近光学镜头组件的反射面a在垂直于主光轴的方向上的投影大于或等于光学镜头组件在垂直于主光轴的方向的高度。如此，可使得来自光学镜头组件的光线均能传播到靠近光学镜头组件的反射面a，从而可提高光线的利用率。
