在一实施例中，显示屏13可以采用LCD(Liquid Crystal Display，液晶显示)屏用于显示信息，LCD屏可以为TFT(Thin Film Transistor，薄膜晶体管)屏幕或IPS(In-Plane Switching，平面转换)屏幕或SLCD(Splice Liquid Crystal Display，拼接专用液晶显示)屏幕。在另一实施例中，显 示屏13可以采用OLED(Organic Light-Emitting Diode，有机电激光显示)屏用于显示信息，OLED屏可以为AMOLED(Active Matrix Organic Light Emitting Diode，有源矩阵有机发光二极体)屏幕或Super AMOLED(Super Active Matrix Organic Light Emitting Diode，超级主动驱动式有机发光二极体)屏幕或Super AMOLED Plus(Super Active Matrix Organic Light Emitting Diode Plus，魔丽屏)屏幕，此处不再赘述。当然，智能终端10也可以不具备显示功能，此时显示屏13可以省略。
在一实施例中，参考图2和图3所示，潜望式摄像装置10b包括摄像模组100和光转向模组300。摄像模组100的数量为多个，多个摄像模组100设置于光转向模组300的外周，每个摄像模组100具有不同的焦距值。多个摄像模组100的光轴平行于同一参考平面(例如图示XY平面)并相交。可以理解，在其它实施例中，多个摄像模组100的光轴也可以不平行同一参考平面，例如与每个摄像模组100的光轴平行的各个参考平面相交。本发明以下实施例将以多个摄像模组100的光轴平行于同一参考平面并相交为例进行说明，但不限定于此。
光转向模组300能将来自物侧并入射至光转向模组300的光线转向，例如将垂直于参考平面(XY平面)入射至光转向模组300的光线转向，转向后的光线能够被选择性地投射至多个摄像模组100中的一个以进行成像，从而用户可以根据使用需求选择短焦镜头或者长焦镜头进行拍摄，以达到较佳的拍摄体验。本发明各实施例的“多个”指至少两个及以上，例如二个、三个、四个等等。图2仅以四个摄像模组100作为示例进行说明，但摄像模组100的数量并不限定为此。
摄像模组100包括感光芯片110和光学镜头120。感光芯片110是一种将光信号转换为电信号的器件。感光芯片110可以为CCD(Charge-coupled Device，电荷耦合元件)感光芯片或CMOS(Complementary Metal-Oxide-Semiconductor，互补金属氧化物半导体)感光芯片。光学镜头120的类型不受限制，例如可以是广角镜头、标准镜头和长焦镜头。光学镜 头120设于感光芯片110的感光路径。多个摄像模组100中的光学镜头120具有不同的焦距，光学镜头120的光轴方向皆平行于参考平面并相交。同一摄像模组100中，光学镜头120具有远离感光芯片110的入射端121和靠近感光芯片110的出射端122。
本发明的多个光学镜头120与光转向模组300能够形成潜望式镜头模组，潜望式镜头模组可以单独生产并组装应用于潜望式摄像装置10b。其中，每一光学镜头120的入射端121均与光转向模组300相对。在一实施例中，光转向模组300包括光转向元件310以及与光转向元件310连接的驱动件320，驱动件320用于带动光转向元件310转动，以使光转向元件310能够在多个位置间进行切换。所述多个位置与所述多个光学镜头120一一对应,且当光转向元件310位于所述多个位置时，光转向元件310可将来自物侧的光线分别转向至多个光学镜头120的入射端。此时，光转向元件310与其中一个光学镜头120满足拍摄状态时，光转向元件310能够使入射至光转向元件310的光线改变方向，例如垂直于参考平面的入射光线改变方向，改变方向后的入射光线平行于满足拍摄状态的光学镜头120的光轴方向，从而改变方向后的入射光线能够穿过光学镜头120并被感光芯片110接收以进行成像。也就是说，当光转向元件310在驱动件320的带动下转动至与其中一个光学镜头120满足拍摄状态时，光转向元件310能使入射至光转向元件310的光线(例如垂直于参考平面的入射光线)在转向后穿过满足拍摄状态的光学镜头120以被感光芯片110接收而成像。
在上述潜望式摄像装置10b中，驱动件320能够带动光转向元件310转动，使得光转向元件310能够将入射至光转向元件310的光线转向，进而根据用户的使用需求可以使得转向后的光线穿过多个光学镜头120中的一个而被同一摄像模组100中的感光芯片110接收。由于每个摄像模组100中的光学镜头120具有不同的焦距，所以用户可以根据使用需求选择短焦镜头或者长焦镜头进行拍摄，以达到较佳的拍摄体验。另外，当该潜望式摄像装置10b应用于智能终端10时，智能终端10只需开设外露光转向元件310的通光孔 101即可，减少了智能终端10开设的通光孔101数量，保证了智能终端10的外观完整性。
当多个光学镜头120的光轴平行于同一参考平面并相交时，由于光线的入射方向与光学镜头120的光轴方向垂直，所以当该潜望式摄像装置10b应用于智能终端10时，可以使光转向模组300、以及同一摄像模组100中的光学镜头120和感光芯片110沿预设方向顺序排布(预设方向为垂直于终端本体10a的厚度方向的任一方向，也即垂直于智能终端10的厚度方向的任一方向)。此时，光学镜头120的光轴方向垂直于智能终端10的厚度方向，从而能够避免由于摄像模组100的体形过长而导致光学镜头120突出于智能终端10的外表面。
在一实施例中，参考图4所示，光转向元件310包括基板311和反射层312。反射层312贴设于基板311，反射层312能够在基板311的表面形成反射面3121，反射面3121能够将入射光线反射以改变入射光线的方向。例如图3和图4示意了入射光路L1和反射光路L2，入射光路L1可以理解为平行于智能终端10的厚度方向，反射光路L2可以理解为平行于满足拍摄状态的光学镜头120的光轴方向，入射光路L1和反射光路L2相互垂直。在一实施例中，反射层312可以为电镀铝层或者电镀银层，也即可以在基板311的表面通过电镀铝或者电镀银的方式形成上述反射层312，从而由所述反射层312形成所述反射面3121。在一具体实施例中，光转向元件310可以为反射镜。可以理解，在其它实施例中，光转向元件310包括棱镜(图未示)，此时，棱镜具有反射面，棱镜能够通过其反射面的反射来使来自物侧的光线转向。需要说明的是，上述反射面皆为光处理面，光处理面面向物侧所在一侧。
在一实施例中，驱动件320能够在垂直于参考平面的方向上伸缩，以控制光转向元件310在所述多个位置切换。请参考图4和图6所示，驱动件320包括多根形状记忆合金线321，每根形状记忆合金线321的延伸方向垂直于参考平面。潜望式镜头模组包括与形状记忆合金线321电性连接的处理器500，处理器500能够通过控制流入每根形状记忆合金线321的电流大小来使 形状记忆合金线321产生不同程度的伸缩，以带动光处理面产生倾斜，使光转向元件310在所述多个位置切换。需要说明的是，处理器500可以为智能终端10的处理芯片，例如CPU(Central Processing Unit，中央处理器)，当然，处理器500也可以为单独的控制模块，例如PLC(Programmable Logic Controller，可编辑逻辑控制器)控制电路等，本发明各实施例对处理器500的种类不作任何限定。
由于形状记忆合金线321具有热缩冷涨的特性，所以多个形状记忆合金线321能够依靠其通入电流大小的不同而得到不同的温度，具有不同温度的形状记忆合金线321产生不同的伸缩量及拉伸量以实现光转向元件310的转动，进而实现光学变焦。为了方便理解，在一具体实施例中，参考图3所示，摄像模组100的数量为四个，四个摄像模组100环绕光转向模组300设置，相邻两个摄像模组100中的光学镜头120的光轴方向相互垂直。光转向元件310具有四个顺次连接的侧边端3101，四个侧边端3101分别与四个摄像模组100一一相对设置，形状记忆合金线321设置于四个侧边端3101所形成的四个角落，即四个侧边端所形成的四个角落皆设有形状记忆合金线321。
当光转向元件310与其中一个光学镜头320满足拍摄状态时，位于光转向元件310同一侧的形状记忆合金线321的长度值相等(例如图4示意了位于光转向元件同一侧的两个形状记忆合金线321a)，位于光转向元件310另一相对侧的形状记忆合金线321的长度值相等且更长(例如图4示意了位于光转向元件另一相对侧的两个形状记忆合金线321b)，此时光转向元件310倾斜。则靠近长度值更长的形状记忆合金线321b所在一侧的光学镜头320满足拍摄状态。形状记忆合金线321基本不占用潜望式摄像装置10b的内部空间，故还可减少尺寸。
当光转向元件310在形状记忆合金线321b的带动下转动至图5所示的另一位置时，光处理面发生倾斜并朝向另一光学镜头120所在一侧，此时位于光转向元件310同一侧的形状记忆合金线321a、321b相比另一相对侧的形状记忆合金线321a、321b伸缩更长。
在一实施例中，参考图3和图4所示，光转向模组300包括安装架330，安装架330具有容纳腔331，光转向元件310和形状记忆合金线321设置于容纳腔331内，形状记忆合金线321的两端分别与安装架330和光转向元件310连接。安装架330在垂直于参考平面的方向上(Z轴方向)开设有与容纳腔331连通的入光孔332，光转向元件310外露于入光孔332，从而入射光线能够通过入光孔332照射至光转向元件310。安装架330在平行于参考平面的方向上开设有与容纳腔331连通的开孔333，开孔333的数量与摄像模组100的数量相等，且摄像模组100位于开孔333所在一侧，从而经光转向元件310转向后的光线能够穿过满足拍摄状态的光学镜头120并被感光芯片110接收而成像。
在一实施例中，参考图2和图3所示，潜望式镜头模组包括音圈马达130，光学镜头120被可驱动地设于音圈马达130的内部，以使音圈马达130能够驱动光学镜头120沿着光学镜头120的光轴方向运动，实现对潜望式摄像装置10的对焦，音圈马达130的数量小于等于光学镜头120的数量，即多个光学镜头120中的至少部分配置有音圈马达130。可以理解，在其它实施例中，摄像模组100为定焦模组，此时音圈马达130由镜座替代，光学镜头120设于镜座的内部。
在一实施例中，潜望式镜头模组还包括滤光片(图未示)，滤光片贴设于光转向元件310并外露于入光孔332。滤光片能够过滤掉入射光中的杂散光，以改善入射光线的品质，提高潜望式摄像装置10的最终成像质量。例如当滤光片为红外截止滤光片时，滤光片能够过滤掉入射光线中的红外部分。
在一实施例中，参考图5所示，潜望式镜头模组包括检测器700，检测器700分别与形状记忆合金线321和处理器500电性连接，检测器700用于检测形状记忆合金线321的电阻值，处理器500能够根据检测器700所检测的电阻值控制流入形状记忆合金线321的电流大小。需要说明的是，检测器700可以是现有技术中任何一种能够检测电阻大小的设备，在此不作任何限定。
由于光转向元件310在与其中一个光学镜头320满足拍摄状态时，此时每根形状记忆合金线321的伸缩量是确定的。故在上述潜望式摄像装置10中，处理器500可以通过检测器700检测每根形状记忆合金线321的阻值来确定每根形状记忆合金线321的长度伸缩量(形状记忆合金线321的长度越大，阻值越大)是否达标，从而处理器500可以进一步根据每根形状记忆合金线321的长度伸缩量来调节流入每根形状记忆合金线321中的电流，以保证形状记忆合金线321伸缩量合适，确保光转向元件310转动至所需位置，实现精确控制。
在其它实施例中，驱动件320除了采用形状记忆合金线321的方式之外，驱动件320也可以为马达，马达的输出端与光转向元件310连接，通过马达带动光转向元件310转动，以实现入射光线可选择性地入射至不同的摄像模组100。当然，也可以采用拨杆拨动光转向元件310旋转，只要能够实现光转向元件310转动的方式，皆在本发明各实施例的保护范围之内，本发明不作任何限定。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
