具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本申请相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本申请的一些方面相一致的装置和方法的例子。
可选地，在本文中，术语“包括”、“包含”或者其任何其他变体意在涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者装置不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者装置所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括该要素的过程、方法、物品或者装置中还 存在另外的相同要素，可选地，本申请不同实施例中具有同样命名的部件、特征、要素可能具有相同含义，也可能具有不同含义，其具体含义需以其在该具体实施例中的解释或者进一步结合该具体实施例中上下文进行确定。
应当理解，尽管在本文可能采用术语第一、第二、第三等来描述各种信息，但这些信息不应限于这些术语。这些术语仅用来将同一类型的信息彼此区分开。例如，在不脱离本文范围的情况下，第一信息也可以被称为第二信息，类似地，第二信息也可以被称为第一信息。取决于语境，如在此所使用的词语"如果"可以被解释成为"在……时"或"当……时"或"响应于确定"。再者，如同在本文中所使用的，单数形式“一”、“一个”和“该”旨在也包括复数形式，除非上下文中有相反的指示。应当进一步理解，术语“包含”、“包括”表明存在所述的特征、步骤、操作、元件、组件、项目、种类、和/或组，但不排除一个或多个其他特征、步骤、操作、元件、组件、项目、种类、和/或组的存在、出现或添加。此处使用的术语“或”和“和/或”被解释为包括性的，或意味着任一个或任何组合。因此，“A、B或C”或者“A、B和/或C”意味着“以下任一个：A；B；C；A和B；A和C；B和C；A、B和C”。仅当元件、功能、步骤或操作的组合在某些方式下内在地互相排斥时，才会出现该定义的例外。
应该理解的是，虽然本申请实施例中的流程图中的各个步骤按照箭头的指示依次显示，但是这些步骤并不是必然按照箭头指示的顺序依次执行。除非本文中有明确的说明，这些步骤的执行并没有严格的顺序限制，其可以以其他的顺序执行。而且，图中的至少一部分步骤可以包括多个子步骤或者多个阶段，这些子步骤或者阶段并不必然是在同一时刻执行完成，而是可以在不同的时刻执行，其执行顺序也不必然是依次进行，而是可以与其他步骤或者其他步骤的子步骤或者阶段的至少一部分轮流或者交替地执行。
可选地，在本文中，采用了诸如S100、S200等步骤代号，其目的是为了更清楚简要地表述相应内容，不构成顺序上的实质性限制，本领域技术人员在具体实施时，可能会先执行S100后执行S200，也可能会先执行S200，再执行S100,等，但这些均应在本申请的保护范围之内。
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。
在后续的描述中，使用用于表示元件的诸如“模块”、“部件”或者“单元”的后缀仅为了有利于本申请的说明，其本身没有特定的意义。因此，“模块”、“部件”或者“单元”可以混合地使用。

基于上述移动终端硬件结构以及通信网络系统，提出本申请各个实施例。
如图3至图7所示，本申请提出的一种摄像头10，应用于移动终端1，用于拍摄。可选地，所述摄像头10包括用于调焦的调焦模组100，摄像头10从拍摄口采集的光线经所述调焦模组100调节后可达到需要的焦距，以满足采用该摄像头10拍摄时所需的清晰度。通过所述调焦模组100调节不同的焦距，可达到自由变焦的目的，满足采用该摄像头10拍摄时在不同场景或不同模式下对图像的清晰度的不同要求。
所述调焦模组100包括安装部(图中未显示)以及至少一个透镜组件101，所述透镜组件101可移动设置在所述安装部上，所述透镜组件101具有位于所述摄像头10的光路传播路径上的第一位置和与所述光路传播路径相错的第二位 置，所述透镜组件101在所述第一位置和第二位置之间移动。
所述摄像头10还包括：
镜头片110，所述镜头片110包括入光面112和出光面111，所述入光面112和所述出光面111相对设置。可选地，所述镜头片110为摄像头10的镜头透镜，所述镜头片110为外部景物反射的光线的入口，外部景物反射的光线经所述镜头片110射入所述摄像头10。
镜头组件120，所述镜头组件120位于所述镜头片110的出光面111一侧，所述镜头片110和所述镜头组件120之间形成所述摄像头10的光路传播路径。可选地，本实施例所述镜头组件120包括图像传感器和图像处理器，所述镜头组件120位于所述镜头片110的出光侧，从所述镜头片110射入的光线射入所述镜头组件120，所述镜头组件120基于接收到的光线信息生成图像。从所述镜头片110射入的光线往所述镜头组件120传播的路径为所述摄像头10的传播路径，所述调焦模组100位于所述镜头片110与所述镜头组件120之间，使得所述调焦模组100中的透镜组件101移动时，可以改变所述光路传播路径(光路传播方向和/或传播距离)。
可选地，摄像头10焦段的长远是根据光线叠加空间的多少实现的，所以焦段的最远、最近距离取决于镜头片110与折射面的通道距离。所述摄像头10的光路在传播过程中，基于所述调焦模组100改变传播距离和/或传播方向(改变镜头光心到镜头组件120的之间的距离)，进行实现摄像头10焦距的调节。所述调焦模组100的调焦原理：通过设置至少一个透镜组件101，且该透镜组件101可以移动到所述光路传播路径上，使得光线经过所述透镜组件101后再传播到镜头组件120，以增加了光路的传播距离和/或改变了传播方向，达到调焦的目的。或者该透镜组件101可以移动到与光路传播路径相错的位置，使得光线无需经过透镜组件101直接传播到镜头组件120，以减小了光路的传播距离和/或改变了传播方向，达到调焦的目的。或者，设置至少两个透镜组件101时，可以设置各个所述透镜组件101的焦距不同，通过切换所述透镜组件101，或者不同焦距的透镜组件101叠加等方式实现所述摄像头10变焦调节。或者设置各个透镜组件101的焦距相同，通过透镜组件101叠加的方式实现所述摄像头10变焦调节。
进一步地，所述调焦模组100包括至少两个透镜组件101时，所述透镜组件101沿与所述光路传播路径平行的方向分布。可选地，所述透镜组件101从所述镜头片110往所述镜头组件120的方向依次排列。如此，所述透镜组件101与所述镜头片110的距离不同，则从所述镜头片110射入的光依次经过不同位置的透镜组件101后射入所述镜头组件120，在所述镜头组件120上的焦点不同(也即焦距不同)。因此，本实施例可以通过控制不同位置的透镜组件101移动至所述第一位置，实现不同焦距的调节。或者，基于所述透镜组件101沿与所述光路传播路径平行的方向分布，可以通过控制光路传播路径上不同透镜组件101移动至所述第一位置，叠加不同位置的透镜组件101的方式，实现不同焦距的调节。如需要远距离拍摄时，将至少一个所述透镜组件101移动至所述第一位置，通过增加第一位置上的所述透镜组件101，以增加透镜组件101的叠加，增加光线的折射、反射或透射，进而增加光的传播距离，实现远距离拍摄。和/或，如需要近距离拍摄时，将部分所述透镜组件101移动至所述第二位置，通过减少第一位置上的所述透镜组件101，以减少透镜组件101的叠加，减少光线的折射、反射或透射，进而减小光的传播距离，实现近距离拍摄。
基于此，相比于通过设置多个焦距不同的摄像头10来变焦的方案，本申请实施例基于所述调焦模组100实现的变焦范围更广，且无需设置多个摄像头10来占用空间，在安装空间有限的情况下，本申请实施例中的摄像头10能够实现更多焦段的调整，增加所述摄像头10的普适性。
可选地，所述摄像头10应用与移动终端1上，所述摄像头10装设在移动终端1的壳体内时，所述调焦组件的安装部固定在所述壳体上。
可选地，所述摄像头10还可以应用到摄像机上，所述摄像头10装设在所述摄像机的壳体内。在摄像机的应用中，所述安装部可以安装在摄像机的壳体上，通过旋转壳体的方式带动所述安装部上的透镜组件101在所述第一位置和所述第二位置之间移动。
在一种实施方式中，所述摄像头10自动驱动所述调焦模组100中的透镜组件101的移动。可选地，所述调焦模组100还包括驱动部103以及活动部(102a、102b、102c)，所述活动部(102a、102b、102c)设置于所述安装部上，所述驱动部103驱动所述活动部(102a、102b、102c)移动，所述透镜组件101设在所述活动部(102a、102b、102c)上，随所述活动部(102a、102b、102c)在所述第一位置和所述第二位置之间移动。
所述驱动部103可以设置在所述安装部上，也可以不设置在所述安装部上。所述驱动部103与控制器连接，所述控制器控制所述驱动部103驱动所述活动部(102a、102b、102c)移动时，带动所述透镜组件101在所述第一位置和所述第二位置之间移动，实现自动调整所述透镜组件101的位置，进而调焦模组100实现自动调焦。可选地，所述控制器可以为独立设置在摄像头10的控制器，也可以摄像头10外部连接的控制器，如摄像头10安装在移动终端1上时，所述摄像头10的驱动部与所述移动终端1的控制器连接，通过移动终端1的控制器控制。
可选地，所述调焦模组100的自动调焦结构以及调焦原理，包括但不限于以下三个实施例中的至少一个：
请参照图3和图4，第一实施例中，如所述活动部为转轴102a，所述透镜组件101安装在所述转轴102a上，所述驱动部为与所述转轴102a连接的电机(图中未显示)，所述转轴102a带动所述透镜组件101在所述第一位置和所述第二位置之间移动。

摄像头打开后，光线能够从镜头片进去所述摄像头内，光线经过所述镜头片后，光线射入所述目标透镜组件，此时控制所述目标透镜组件的透镜镜片上的电阻层不通电，所述透镜镜片处于不透光状态，所述透镜镜片将光反射所述镜头片的反射面(所述镜头片朝向所述摄像头内侧的面为反射面)，镜头片的反射面再将光反射到所述目标透镜组件，所述目标透镜组件的所述电阻层上电，使得所述电阻层所在区域为透光状态，光线经过所述目标透镜镜片时目标透镜组件的传感元件采集光线形成的图像信息，同时光线从所述目标透镜镜片折射后射入所述镜头组件，在所述镜头组件上形成图像，所述镜头组件基于所述传感器采集的图像以及透镜组件采集的图像形成最终的目标图像。
如所述目标透镜组件具有至少一个时，控制所述目标透镜组件的至少一透镜镜片的至少一区域为不透光状态和/或透光状态。
所述目标透镜组件均通过电阻层通电或断电的方式来切换各个目标透镜组件为透光状态或不透光状态。

依据光路传播方向上所述目标透镜组件排列顺序或预设顺序控制所述目标透镜的至少一透镜镜片的至少一区域为不透光状态和/或透光状态。
可选地，光路传播方向是指：光从镜头片往所述镜头组件方向传输方向，所述目标透镜组件的排列顺序是指从靠近所述镜头片往靠近所述镜头组件的方向的排列顺序。具有多个所述目标透镜组件时，通过多个目标透镜组件的叠加来增加所述摄像头的焦距，使得所述移动终端能够拍摄更远的景物。所述预设顺序可以为预先设定的各个透镜组件的排序，如预设设定A透镜组件、B透镜组件、C透镜组件依次排列，则在确定所述目标透镜组件包括A透镜组件、B透镜组件、C透镜组件时，则先控制A透镜组件的至少一透镜镜片的至少一区域为不透光状态和/或透光状态，再依次控制B透镜组件和C透镜组件的至少一透镜镜片的至少一区域为不透光状态和/或透光状态。或者，在其它实施例中，所述预设顺序还可以为固定的排列顺序，如预设排列顺序为1325，也即先控制第一个目标透镜组件的至少一透镜镜片的至少一区域为不透光状态和/或透光状态，然后再控制第三个目标透镜组件的至少一透镜镜片的至少一区域为不透光状态和/或透光状态，然后依次控制第二个目标透镜组件和第五个目标透镜组件。可选地，上述所列举的预设顺序为具体的一种实施例，并不限于该实施例，其它排列顺序也在本申请的保护范围。可选地，上述的第一个目标透镜组件为靠近镜头片的透镜组件，而第五个透镜组件为靠近镜头组件的透镜组件，第二个透镜组件至第四个透镜组件位于所述第一个目标透镜组件和第五个目标透镜组件之间。
多个所述目标透镜组件的具体控制过程包括按照所述目标透镜组件的排列顺序控制所述目标透镜的至少一透镜镜片的至少一区域为不透光状态和/或透光状态。可选地，以下为一种具体的控制原理：
光线从镜头片进入所述摄像头后，光线射入靠近所述镜头片的第一目标透镜组件，此时第一目标透镜组件的透镜镜片上的电阻层不通电，所述电阻层所在区域处于不透光状态，也即所述第一目标透镜组件不透光，所述透镜镜片将光反射所述镜头片的反射面(所述镜头片朝向所述摄像头内侧的面为反射面)后再反射进入所述第一目标透镜组件，此时所述第一目标透镜组件的所述电阻层上电，使得所述电阻层所在区域为透光状态，光线经过所述第一目标透镜组件的透镜镜片时，所述第一目标透镜组件的传感元件采集光线形成的图像信息，同时光线从所述透镜镜片折射后，射入第二目标透镜组件，此时所述第二目标透镜组件的透镜镜片的电阻层不通电，电阻层处于不透光状态，所述第二目标透镜组件不透光，第二目标透镜组件的透镜镜片将光线反射到所述第一目标透镜组件上，并基于所述第一目标透镜组件反射后再射入所述第二目标透镜组件，此时，光线射入所述第二透镜组件，所述第二透镜组件的透镜镜片的电阻层此时通电，电阻层处于透明状态，光线经过第二目标透镜组件的透镜镜片时，第二目标透镜组件的传感元件采集光线形成的图像信息，同时光线从第二目标透镜组件的透镜镜片折射后，射入第三目标透镜组件，如此依次经过各个位于第一位置的目标透镜组件反射、折射或透射后，最后射入所述镜头组件，在所述镜头组件上形成图像，所述镜头组件基于所述传感器采集的图像以及透镜组件采集的图像形成最终的目标图像。
本实施例中，光线从镜头片射入目标透镜组件时，目标透镜组件先反射光线，再折射或透射光线，增加光线的传输距离，从而增加拍摄距离，所述目标 透镜组件中的传感元件采集该距离采集到的图像信息，如此基于不同目标透镜组件对应有不同距离的图像信息，在生成最终的目标图像时，基于各个具体的图像信息进行合成，使得图像清晰度更佳。
