为了使本申请所要解决的技术问题、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。

为了提升平板电脑、智能手机等移动终端的摄像效果，往往会在移动终端中安装潜望式摄像模组。另外，随着移动终端制作越来越薄，相应的移动终端的摄像模组的体积也需要制作越来越小。当前的镜头中均使用圆形镜片搭配圆形镜筒制作，而潜望式摄像模组中棱镜往往需要制作较小，其反射的区域往往为矩形区域，相应的反射的光场也矩形光场。当棱镜反射的光场经过圆形镜片组时，往往仅利用各圆形镜片中间的部分区域，则圆形镜片于光场之外存在较大的区域，使得圆形镜片利用的区域较小，而且相应圆形镜片尺寸需要制作较大，导致潜望式摄像模组体积较大。
请参阅图1，现对本申请提供的潜望式摄像模组10进行说明。所述潜望式摄像模组10，包括机壳11和光学系统12，光学系统12安装在机壳11中，通过机壳11来支撑与保护光学系统12。光学系统12具有第一光轴121和第二光轴122，第二光轴122垂直于第一光轴121。光学系统12包括棱镜123、透镜组124和图像传感器125，其中图像传感器125用于接收并感应光线，进而得到拍摄图像。棱镜123具有入光面1231、出光面1232和反射斜面1233，出光面1232垂直于入光面1231，反射斜面1233倾斜于入光面1231和出光面1232，反射斜面1233将入光面1231射入的光线反射，经出光面1232射出，则沿第一光轴121射入的光线，经棱镜123的反射斜面1233反射后，沿第二光轴122射出。透镜组124和图像传感器125沿第二光轴122设置，机壳11上设有矩形开窗110，矩形开窗110沿第一光轴121设于棱镜123靠近物像的一侧，这样从矩形开窗110进入到棱镜123的物像光线，经反射斜面1233反射后，进入透镜组124对焦调整后，到达图像传感器125。矩形开窗110与反射斜面1233相适配，以使矩形开窗110射入到反射斜面1233的光场与反射斜面1233相匹配，以减少进入棱镜123的杂光，以提升成像质量。透镜组124包括多个矩形透镜1241，多个矩形透镜1241沿第二光轴122设置，以进行调焦，保证成像质量。矩形透镜1241指从一面看，外廊呈矩形的透镜，如本申请中沿第二光轴122的方向看，矩形透镜1241的外廊呈矩形。使用矩形透镜1241，并使矩形透镜1241与反射斜面1233的反射光场相适配，由于棱镜123的反射斜面1233反射的光场(即反射光场)呈矩形，而矩形透镜1241与反射光场适配，这样可以使矩形透镜1241上的更多区域参与光线的调节，提升矩形透镜1241上参与光线调节区域的面积占该矩形透镜1241面积的比例，减小冗余面积；则在透射相同的反射光场的情况下，相比于圆形镜片可以将矩形透镜1241制作更小，进而可以将该潜望式摄像模组10体积制作更小。
本申请提供的潜望式摄像模组10，与现有技术相比，本申请潜望式摄像模组10，通过在机壳11上设置与棱镜123相适配的矩形开窗110，可以减少从矩形开窗110进入棱镜123的杂光，以避免影响成像质量；使用矩形透镜1241形成透镜组124，将矩形透镜1241与棱镜123的反射光场相适配，可以提升矩形透镜1241的有效利用面积，从而在透射相同的反射光场的情况下，相比于圆形镜片可以将矩形透镜1241制作更小，进而可以将该潜望式摄像模 组10体积制作更小。
在一个实施例中，请参阅图1，透镜组124还包括镜筒1245，镜筒1245安装于机壳11中，多个矩形透镜1241安装在镜筒1245中，通过镜筒1245来支撑多个矩形透镜1241，以方便安装固定各矩形透镜1241，进而方便将透镜组124安装在机壳11中，便于组装。当然，在一些实施例中，也可以将矩形透镜1241直接固定在机壳11中。
在一个实施例中，请参阅图1，棱镜123的反射斜面1233上设有矩形反射区12331，矩形反射区12331用于全反射光线，以便从矩形开窗110进入的光线可以完全反射出，提升光线利用率，进而提升成像质量。
在一个实施例中，请参阅图2，透镜组124的各矩形透镜1241采用激光焊接相连，这样可以减少镜筒1245的使用，并且各矩形透镜1241的边缘无需制作坎合位，进而可以减小矩形透镜1241的体积，进而可以将该潜望式摄像模组10制作更小。
在一个实施例中，请参阅图3，透镜组124可以包括两个、三个、四个、五个等数量的矩形透镜1241，具体可以根据需求进行设置。
