需要说明的是，“沿图像采集模块200的光轴200b”并不表示入射至光传感器201的所有光线的传播方向都完全与光轴200b的方向重合或平行。例如，参阅图2所示，沿图像采集模块200的光轴200b入射光传感器201的光线中，有部分光线与光轴200b的方向重合或平行，还有部分光线与光轴200b呈一定角度，只要这些光线能够进入图像采集模块200并照射光传感器201以适应光传感器201成像需要即可。It should be noted that "along the
结合图3所示，在一些实施例中，图像采集模块200包括固体镜头202，固体镜头202和光传感器201依次沿图像采集模块200的光轴200b布置，图像采集模块200的光轴200b可以由固体镜头202的光轴确定，确切的说，固体镜头202的光轴与图像采集模块200的光轴200b同轴，也即，光线经固体镜头202进行聚焦或滤光等光学处理后入射图像采集模块200的光传感器201。固体镜头202内含有若干凸透镜和凹透镜形成的镜片组，以利用镜片组对光线产生聚焦或滤光等光学处理。图3中仅仅示意性地示出了固体镜头202对光线光路的调整，本申请技术方案不限于此。3 , in some embodiments, the
在一些实施例中，图像采集模块200可以是固定设置在机壳101内，机壳101上设置有能够供机壳101外部光线入射至图像采集模块200的透光部件或透光区域，从而适应图像采集模块200的拍摄需要。透光部件可以是透明塑料或透明玻璃，机壳101也可以是局部采取透明材料形成透光区域，也可以是全部采取透光材料，从而光线能够从外界穿透至移动终端内并入射图像采集模块200的受光面200a，以适应图像采集模块200的拍摄需要。In some embodiments, the
在另一些实施例中，图像采集模块200还可以采用可运动的形式设置于本体100。例如，本体100上开设有收容图像采集模块200的收容槽，图像采集模块200相对本体100运动并可选择性地位于收容状态和伸出状态，在收容状态下，图像采集模块200位于收容槽内，此时的图像采集模块200被本体100的外围的机壳101遮挡，继而避免图像采集模块200外露破坏移动终端整体美观。在伸出状态下，图像采集模块200从收容槽伸出，从而使得外界光线能够经图像采集模块200的光轴200b入射图像采集模块200内，以适应图像采集模块200成像需要。In other embodiments, the
需要说明的是，图像采集模块200可以作为前置拍摄使用，例如，图1示出的移动终端中，图像采集模块200的受光面200a外露于显示屏110的可显示区110a所在一侧。在另一些实施例中，适应调整图像采集模块200在本体100内的设置位置，使得受光面200a背向显示屏110的可显示区110a的一侧，即可使得图像采集模块200作为后置拍摄使用，对于图像采集模块200相对本体100的拍摄视角，在此不作限定。It should be noted that the
在一些实施例中，图像采集模块200包括液体镜头210，液体镜头210的光轴与固体镜头202的光轴同轴设置，液体镜头210能够实现微距变焦，提高图像采集模块200的调焦性能。In some embodiments, the
结合图4至图7所示，液体镜头210包括封闭腔体211以及充盈于封闭腔体211内的第一导电液体212、绝缘液体213和第二导电液体214。由于封闭腔体211为封闭状态，从而其内的第一导电液体212、绝缘液体213和第二导电液体214不会发生泄露。4 to 7 , the
封闭腔体211呈扁平状，具有相背设置的入光面211a和出光面211b，外界光线能够从入光面211a进入封闭腔体211内，并在穿过封闭腔体211内的第一导电液体212、绝缘液体213和第二导电液体214后，光线从出光面211b穿出。The
第一导电液体212、绝缘液体213和第二导电液体214互不相溶且密度相等，第一导电液体212和第二导电液体214由绝缘液体213隔开，第一导电液体212与绝缘液体213的分界处形成第一光学界面S1，第二导电液体214与绝缘液体213的分界处形成第二光学界面S2，第一光学界面S1和第二光学界面S2均位于入光面211a和出光面211b之间，其中，封闭腔体211的外壁设有第一电极215和第二电极216，第一电极215与第一导电液体212电性连接，用以通电时调整第一光学界面S1的曲率，第二电极216与第二导电液体214电性连接，用以通电时调整第二光学界面S2的曲率。The first
由于第一电极215和第二电极216分别对第一导电液体212和第二导电液体214进行电润湿时，改变第一电极215和第二电极216的电压，能够改变第一光学界面S1和第二光学界面S2与封闭腔体211的内壁的接触角，从而使得第一光学界面S1和第二光学界面S2的曲率发生改变，以适应对光线进行汇聚或发散的需要，也即通过这种结构实现了焦距的可控调节，提升图像采集模块200的调焦性能。When the
需要说明的是，由于第一光学界面S1和第二光学界面S2通过曲率的改变，能够满足调焦的需要，因此，第一光学界面S1和第二光学界面S2在进行调焦时，具有光学焦点。It should be noted that, since the first optical interface S1 and the second optical interface S2 can meet the needs of focusing by changing the curvature, the first optical interface S1 and the second optical interface S2 have optical focus.
该实施例中，第一光学界面S1和第二光学界面S2与封闭腔体211的内壁相接触的位置，每一处的接触角相等，确切的说，第一光学界面S1和第二光学界面S2是以液体镜头210的光轴为旋转中心的旋转体。In this embodiment, the first optical interface S1 and the second optical interface S2 are in contact with the inner wall of the
第一电极215呈环形，环设于封闭腔体211的外壁，从而第一导电液体212与封闭腔体211的各接触位置电润湿效应一致，第一光学界面S1将呈现为球面。例如，在一些实施例中，第一电极215通电后，第一光学界面S1呈球面，从而具有聚光焦点，以对光束具有会聚或发散效果。The
在一些实施例中，第二电极216呈环形，环设于封闭腔体211的外壁，第二电极216通电后，第二光学界面S2呈球面，从而具有聚光焦点，以对光束具有会聚或发散效果。In some embodiments, the
在一些实施例中，可以采取玻璃或亚克力板等透明材料制作封闭腔体211，从而使得封闭腔体211的侧壁为透明的，能够供外界光线穿入封闭腔体211。In some embodiments, the
在图像采集模块200中，光传感器201位于封闭腔体211的出光面211b所在一侧，外界光线能够穿过封闭腔体211的入光面211a，经第一光学界面S1和第二光学界面S2折射后入射光传感器201。从而通过改变第一电极215和第二电极216的电压，对第一光学界面S1和第二光学界面S2的形状进行调整时，光线将会不同程度的汇聚或发散，继而能够对入射至光传感器201的光线进行调整，实现调焦。In the
液体镜头210设置于固体镜头的远离光传感器201的一侧，也就是说，经过液体镜头210后的光线将进一步穿过固体镜头，最终入射至光传感器201进行成像。在其他实施例中，液体镜头210设置于固体镜头的镜片之间，从而在固体镜头的镜片之间进行调光，以进行微距调焦。The
结合图4和图5所示，封闭腔体211的内壁设有亲油疏水层217，从而使得第一导电液体212和第二导电液体214能够在通电情况下产生更好的电润湿效果，进而适应光学调焦需要。4 and 5, the inner wall of the
在一些实施例中，第一导电液体212的折射率与绝缘液体213的折射率不同，从而在光线从第一导电液体212进入绝缘液体213时，将在两者之间的第一光学界面S1发生折射，且由于第一电极215能够通过改变电流方向或大小，来改变第一光学界面S1的形状，因此，通过这种结构设置，可以实现对光线不同程度汇聚或发散，以适应调焦需要。相应地，第二导电液体214的折射率与绝缘液体213的折射率不同，进而第二电极216通电时调整第二光学界面S2的曲率，能够对从第一光学界面S1出射至绝缘液体213的光线进行二次折射，以使得液体镜头210整体上能够对光线进行多种不同程度的汇聚，进而提升调焦性能。In some embodiments, the refractive index of the first
在一些实施例中，第一导电液体212的折射率和第二导电液体214的折射率相同，从而光线在穿过第一光学界面S1和第二光学界面S2时折射角相同，这种设置有利于进行光路模拟，以便于设置调焦参数。In some embodiments, the refractive index of the first
在一些实施例中，当第一电极215的电压大于或小于临界电压时，第一光学界面S1为曲面，其中，临界电压为第一电极215使得第一光学界面S1呈平面时的电压(参考图4所示)。In some embodiments, when the voltage of the
需要说明的是，第一电极215的电压大于临界电压时，第一光学界面S1可以是凸面，相应地，第一电极215的电压小于临界电压时，第一光学界面S2为凹面，也即是说，临界电压是作为第一光学界面S1在凹面和凸面进行切换的第一电极215的电压分界。It should be noted that when the voltage of the
在一些实施例中，当第二电极216的电压大于或小于临界电压时，第二光学界面S2为曲面，其中，临界电压为第二电极216使得第二光学界面S2呈平面时的电压。In some embodiments, when the voltage of the
第二电极216的电压大于临界电压时，第二光学界面S2可以是凹面，相应地，第二电极216的电压小于临界电压时，第二光学界面S2为凸面。When the voltage of the
结合图4至图7所示，由于第一电极215可以独立调控第一光学界面S1的曲率，第二电极216可以独立调控第二光学界面S2的曲率，从而使得第一光学界面S1和第二光学界面S2可以呈现多种折射组合，使得焦距变化范围更广，能够适应微距到远焦的调焦需要，提高调焦性能。4 to 7 , since the
在一些实施例中，封闭腔体211的外壁设有ITO涂层，以形成相应的第一电极215或第二电极216，利用ITO涂层形成的第一电极215和第二电极216，有利于通过贴片封装的方式将图像采集模块200连接与相应的电路板相连。In some embodiments, the outer wall of the
