Description

摄像头组件和终端设备
本申请要求于2018年12月07日提交的申请号为201811497066.0、发明名称为“摄像头组件和终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及光学防抖技术领域，特别涉及一种摄像头组件和终端设备。
背景技术
生活中人们经常使用终端设备(如智能手机、平板电脑等)进行拍照，由此终端设备的拍照质量已经成为衡量终端设备的重要标准之一。
用户在使用终端设备进行拍照时，经常会出现因手抖动而使拍出的照片不清晰的问题，为了解决这一问题，部分终端设备具有拍照防抖功能，具备这种功能的终端设备的摄像头组件在结构上主要包括镜头、致动部件、感光元件和处理器，其中，致动部件与镜头固定连接，用于在处理器的控制下使镜头移动。当用户使用终端设备拍照产生抖动时，处理器可以检测到终端设备的抖动方向和抖动量，然后基于抖动方向和抖动量，确定镜头的调整方向和调整量，并控制致动部件带动镜头在垂直于光线的平面内进行调整。例如，如果用户拍照时由于抖动使终端设备向某一个方向(如左方)移动，则处理器可以控制致动部件带动镜头，向与上述方向相反的方向(如右方)移动，以使镜头与景物保持相对静止。
在实现本申请的过程中，发明人发现相关技术至少存在以下问题：
上述致动部件仅限于在垂直于光线的平面内对镜头进行调整，而抖动是用户无意识下产生的动作，抖动方向并非都是垂直于光线的平面，所以上述致动部件对镜头的致动效果较差，从而导致具备该致动部件的终端设备的防抖效果也较差。
发明内容
为了解决相关技术中的问题，本发明实施例提供了一种摄像头组件和终端设备。所述技术方案如下：
第一方面，提供了一种摄像头组件，该摄像头组件包括镜头光学器件1和致动部件2，其中：致动部件2包括两个活动块21、位于每个活动块21两侧的固定支架22和多个电控伸缩件23；镜头光学器件1位于两个活动块21之间，分别与两个活动块21相固定；每个活动块21分别通过弹性件3悬空式安装在固定支架22上；每个活动块21与两侧的固定支架22之间分别连接有电控伸缩件23。
其中，活动块21是具有一定高度和宽度的部件，如图3所示，活动块21可以具有一定高度、宽度和厚度的柱状结构，在镜头光学器件1的两侧分别设置有一个活动块21，为方便描述不妨记为第一活动块21A和第二活动块21B。如图1和2所示，两个活动块21可以竖直 立在两侧的固定支架22之间，如图4所示，活动块21也可以平躺在两侧的固定支架22之间。本实施例对活动块21的具体结构以及在两侧的固定支架22之间的放置不做具体限定，可以根据摄像头组件的空间布置而灵活设置。
本申请实施例所示的方案，如图1、2和5所示，镜头光学器件1位于两个活动块21之间，并且固定在两个活动块21上，这样镜头光学器件1和两个活动块21便可以作为一个整体，活动块21运动时，镜头光学器件1也可以跟着活动块21发生同步运动。为了使活动块21运动过程中，不受相邻零部件的干涉，相应的，每个活动块21通过弹性件3悬空式安装在固定支架22上，也即是，活动块21的两侧通过弹性件3与固定支架22相固定，而且，活动块21与固定支架22之间不相接触，这样，活动块21便可以悬空活动安装在固定支架22上，且活动块21可以相对于固定支架22发生转动。
为了使活动块21可以相对于固定支架22发生位移或者旋转，相应的，每个活动块21与两侧的固定支架22之间连接有至少两个电控伸缩件23。当电控伸缩件23发生伸缩变化时，由于固定支架22不可动，而活动块21处于悬空状态，电控伸缩件23便可以拉动或者推动与之相连的活动块21相对于固定支架22运动，例如，电控伸缩件23可以使活动块21带动镜头光学器件1在平面内进行平移或者在空间内绕着某一个轴进行旋转。
在一种可能的实现方式中，如图1所示，每个活动块21的上部与两侧的固定支架22之间分别连接有电控伸缩件23，每个活动块21的下部与两侧的固定支架22之间分别连接有电控伸缩件23。
本申请实施例所示的方案，致动部件2包括八个电控伸缩件23，每个活动块21上设置有四个电控伸缩件23，电控伸缩件23的这种设置，可以达到使用最少数量的电控伸缩件23来达到镜头光学器件1可以分别绕着三个旋转轴旋转的效果，进而可以节约布置空间。
在一种可能的实现方式中，每个电控伸缩件23包括活动块连接端、支架连接端和连接活动块连接端与支架连接端的伸缩丝；位于活动块21上部的活动块连接端的高度高于所在电控伸缩件23的支架连接端的高度，位于活动块21下部的活动块连接端的高度低于所在电控伸缩件的支架连接端的高度。
本申请实施例所示的方案，如图8所示，活动块连接端r的高度高于支架连接端t的高度，活动块连接端s的高度低于支架连接端u的高度，其中，活动块连接端r位于活动块21的上部，活动块连接端r所在电控伸缩件23的支架连接端为支架连接端t，活动块连接端s位于活动块21的下部，活动块连接端s所在电控伸缩件23的支架连接端为支架连接端u。
也可以参考图9所示，活动块连接端a的高度高于支架连接端d的高度，活动块连接端b的高度低于支架连接端c的高度，其中，活动块连接端a位于活动块21的上部，活动块连接端a所在电控伸缩件23的支架连接端为支架连接端d，活动块连接端b位于活动块21的下部，活动块连接端b所在电控伸缩件23的支架连接端为支架连接端c。
如图1、图2、图5、图8和图9中位于活动块21上部的电控伸缩件23的伸缩丝向下倾斜，位于活动块21下部的电控伸缩件23的伸缩丝向上倾斜。
在一种可能的实现方式中，在位于同一个固定支架上的两个支架连接端中，第一支架连接端的高度低于第二支架连接端的高度，其中，第一支架连接端是与位于活动块21上部的活动块连接端属于同一电控伸缩件23的支架连接端，第二支架连接端是与位于活动块21下部的活动块连接端属于同一电控伸缩件23的支架连接端。
本申请实施例所示的方案，如图8所示，支架连接端t的高度低于支架连接端u，其中，活动块连接端r位于活动块21的上部，与活动块连接端r属于同一电控伸缩件23的支架连接端为支架连接端t，活动块连接端s位于活动块21的下部，与活动块连接端s属于同一电控伸缩件23的支架连接端为支架连接端u。
在电控伸缩件23的伸缩丝为SMA丝的情况下，活动块21与固定支架22之间的四个SMA丝交叉设置，也即是，如图1、2、5、8和图11所示的电控伸缩件23的SMA丝的布局方式，既能够较好的控制镜头光学器件1的旋转，又可以节约布置空间。这是因为，SMA丝的变形量通常较小，为了在不损坏SMA丝的情况下提高其变形量，那么需要SMA丝足够的长，在相同的占空空间情况下，与图9和10相比，图1、2、5、8和图11中SMA丝的布局方式，SMA丝的长度比较长，进而，图1、2、5、8和图11所示的电控伸缩件23的SMA丝的布局方式既可以较好的控制镜头光学器件1的旋转，又可以节约布置空间。
在一种可能的实现方式中，对于每个活动块21与一侧固定支架22之间的两个电控伸缩件23，连接活动块21上部的电控伸缩件23的伸缩丝与连接活动块21下部的电控伸缩件23的伸缩丝不相接触。
本申请实施例所示的方案，如图11所示，第一电控伸缩件231的伸缩丝与第四电控伸缩件234的伸缩丝所在的平面、第二电控伸缩件232的伸缩丝与第三电控伸缩件233的伸缩丝所在的平面相平行，且之间具有间隙，该间隙值为预设数值。这样，当第一电控伸缩件231与第四电控伸缩件234通电收缩，而第二电控伸缩件232和第三电控伸缩件233未通电收缩时，第二电控伸缩件232的伸缩丝不会干涉第一电控伸缩件231对活动块21的施加的作用力，第三电控伸缩件233的伸缩丝也不会干涉第四电控伸缩件234对活动块21的施加的作用力。
在一种可能的实现方式中，每个电控伸缩件23包括活动块连接端、支架连接端和连接活动块连接端与支架连接端的伸缩丝；位于活动块21上部的活动块连接端的高度低于所在电控伸缩件23的支架连接端的高度，位于活动块21下部的活动块连接端的高度高于所在电控伸缩件23的支架连接端的高度。
本申请实施例所示的方案，如图10所示，活动块连接端j的高度低于支架连接端i的高度，其中，活动块连接端j位于活动块的上部，活动块连接端j所在电控伸缩件23的支架连接端为支架连接端i。活动块连接端k的高度高于支架连接端m的高度，其中，活动块连接端k位于活动块的下部，活动块连接端k所在电控伸缩件23的支架连接端为支架连接端m。
如图1、2、5、8、9、10和图11所示的电控伸缩件23的布局方式，均能够实现当电控伸缩件23的伸缩丝发生收缩时，使活动块21带动镜头光学器件1绕着三维空间中任意一个旋转轴进行旋转。
在一种可能的实现方式中，伸缩丝为形状记忆合金丝。
本申请实施例所示的方案，电控伸缩件23的伸缩丝可以是形状记忆合金丝，形状记忆合金丝也可以简称为SMA(Shape Memory Alloy，形状记忆合金)丝，当处理器对电控伸缩件23通电时，其伸缩丝在通电的状态下，加热产生热量，温度升高，进而发生收缩，对活动块21产生拉力。电控伸缩件23的伸缩丝为SMA丝的情况，结构简单，所使用的零部件较少，可以减少摄像头组件的零部件个数，节约终端设备的内部空间，有利于终端设备的轻量化和轻薄化发展。
在一种可能的实现方式中，每个弹性件3为金属弹性件，每个活动块连接端和每个支架 连接端为导电端子，每个弹性件3与同侧的活动块连接端电性连接。
本申请实施例所示的方案，在伸缩丝为SMA丝的情况下，活动块连接端和支架连接端均为导电端子，其中，位于活动块21上的活动块连接端可以接地。为了节约布置空间，弹性件3可以是金属弹性件，每个弹性件3与同侧的活动块连接端电性连接，弹性件3再与摄像头组件的基板上的接地端电性连接，既实现了活动块连接端的接地又减少了布置空间，无需在活动块连接端另外导出一个接地线，直接借用金属的弹性件3即可。
在一种可能的实现方式中，每个活动块21两侧的弹性件3关于活动块21的铅垂线相对称。
本申请实施例所示的方案，每个活动块21两侧的弹性件3的形状和结构相同，且弹性系数相等，这样，活动块21的两侧分别通过完全相同的弹性件3固定在固定支架3上，进而，在电控伸缩件23未通电的情况下，活动块21在两侧的固定支架22之间不会发生倾斜的情况，每个活动块21稳固在相固定的两个固定支架22之间，也提高了镜头光学器件1的稳固性。
在一种可能的实现方式中，镜头光学器件1包括反射镜11和反射镜安装座12，反射镜11安装在反射镜安装座12中；反射镜安装座12位于两个活动块21之间，分别与两个活动块21相固定。
本申请实施例所示的方案，如图2所示，镜头光学器件1可以包括反射镜11和反射镜安装座12，反射镜11可以是如图1和2所示的反射板，也可以是如图3所示的棱镜。反射镜11安装在反射镜安装座12中，反射镜安装座12位于两个活动块21之间，反射镜安装座12的相对两个侧壁分别与两个活动块21相固定，反射镜安装座12作为反射镜11的安装底座可以起到保护反射镜11的作用。
在一种可能的实现方式中，致动部件2还包括弹性限位件5；弹性限位件5的两端分别固定在两个固定支架22上，弹性限位件5的中部固定在反射镜安装座12上。
本申请实施例所示的方案，在实施中，弹性限位件5的结构可以如图6所示，包括第一固定端51、第二固定端52和第三固定端53，弹性限位件5的第一固定端51固定在如图1所示的第四固定支架22D上，弹性限位件5的第二固定端52固定在如图1所示的第二固定支架22B上，弹性限位件5的第三固定端53固定在如图2所示的反射镜安装座12背对反射镜11的表面上。这样，镜头光学器件1通过四个弹性件3和一个弹性限位件5相固定，两个活动块21和两个活动块21之间的镜头光学器件1作为一个整体，在三个位置处通过弹性件相固定和支撑，根据三角形稳定性，进而，可以提高镜头光学器件1在电控伸缩件23未通电的情况下的稳固性，避免了镜头光学器件1的晃动。
在一种可能的实现方式中，摄像头组件还包括处理器；
处理器分别与每个电控伸缩件23电性连接，用于在检测到终端设备启动拍照功能后每当达到预设周期时，获取终端设备在当前周期内的位移信息和姿态变化信息，基于位移信息和姿态变化信息，确定每个电控伸缩件23的控制电流值，基于每个电控伸缩件23的控制电流值，对电控伸缩件23进行伸缩控制。
其中，位移信息指的是终端设备在平面内位置信息的变化，例如，终端设备在某一个平面内向某一个方向某个平移量，例如，在垂直于光线轴的平面内向左平移了一毫米。姿态变化信息指的是终端设备在空间内姿态信息的变化，例如，终端设备在空间内绕着某一个轴旋转了某个角度。用户手持终端设备拍照发生的抖动使终端设备发生的变化即是终端设备的位 移信息和姿态变化信息综合的结果。
控制电流值可以是对应一个较大电流的控制信号，也可以是对应一个较小电流的控制信号，还可以是对应零电流的控制信号。这样，进行伸缩的电控伸缩件23通入的电流可以是一个值较大的电流，不进行伸缩的电控伸缩件23通入的电流可以是一个值较小的电流或者零电流。
本申请实施例所示的方案，处理器获取终端设备在当前周期内的位移信息和姿态变化信息之后，可以基于位移信息和姿态变化信息，确定各个电控伸缩件23的控制电流值，之后，处理器便可以通过控制摄像头组件的供电部件或者终端设备的供电部件，向各个电控伸缩件23通入的电流值。
在一种可能的实现方式中，摄像头组件还包括处理器；处理器分别与每个电控伸缩件电性连接，用于：在检测到终端设备启动拍照功能后每当达到预设周期时，获取终端设备在当前周期内的位移信息和姿态变化信息；确定位移信息在预设的第一方向上的第一位移分量、在预设的第二方向上的第二位移分量和在预设的第三方向上的第三位移分量，并确定姿态变化信息在预设的第一旋转轴上的第一旋转角度分量、在预设的第二旋转轴上的第二旋转角度分量和在预设的第三旋转轴上的第三旋转角度分量，其中，第一方向、第二方向、第三方向相互垂直，第一旋转轴、第二旋转轴和第三旋转轴相互垂直，第一方向与第一旋转轴垂直，第二方向与第二旋转轴垂直，第三方向与第三旋转轴垂直；基于第一位移分量和第一旋转角度分量，确定在第一旋转轴上的第一补偿旋转角度，基于第二位移分量和第二旋转角度分量，确定在第二旋转轴上的第二补偿旋转角度，基于第三位移分量和第三旋转角度分量，确定在第三旋转轴上的第三补偿旋转角度；基于第一补偿旋转角度、第二补偿旋转角度和第三补偿旋转角度，确定每个电控伸缩件23的控制电流值，基于每个电控伸缩件23的控制电流值，对电控伸缩件23进行伸缩控制。
其中，第一位移分量、第二位移分量和第三位移分量是矢量具有正负，正负表示平移方向，例如，第一方向上的第一位移分量要么是沿着第一方向，要么是沿着第一方向的反向。同样，第一旋转角度分量、第二旋转角度分量和第三旋转角度分量也具有正负，正负表示旋转方向，例如，第一旋转轴上的第一旋转角度分量要么是顺时针绕着第一旋转轴的角度，要么是逆时针绕着第一旋转轴的角度。
旋转角度与补偿旋转角度互为相反，两者方向相反，数值相等，例如，旋转角度为绕着旋转轴进行顺时针旋转的角度，补偿旋转角度为绕着该旋转轴进行逆时针旋转的角度。
本申请实施例所示的方案，处理器根据第一位移分量确定对应的第一位移旋转角度，再对第一位移旋转角度与第一旋转角度分量进行矢量运算，矢量运算之后对得到的角度取相反数，得到在第一旋转轴上的第一补偿旋转角度。例如，如果两者的旋转方向一致则相加，如果两者的旋转方向相反则相减，这样矢量计算之后，可以得到角度β，然后处理器将负β确定为补偿旋转角度，这样便可以得到在第一旋转轴上的第一补偿旋转角度。同理可以得到在第二旋转轴上的第二补偿旋转角度和在第三旋转轴上的第三补偿旋转角度。
之后，处理器可以基于第一补偿旋转角度、第二补偿旋转角度和第三补偿旋转角度，确定每一个电控伸缩件23的控制电流值，基于每个电控伸缩件23的控制电流值，对电控伸缩件23进行伸缩控制。例如，处理器可以通过控制摄像头组件的供电部件向第一电控伸缩件231通入10安培的电流，向第二电控伸缩件232通入1安培的电流，向第三电控伸缩件233 通入10安培的电流，向第四电控伸缩件234通入1安培的电流，向第五电控伸缩件235通入10安培的电流，向第六电控伸缩件236通入1安培的电流，向第七电控伸缩件237通入10安培的电流，向第八电控伸缩件238通入1安培的电流。
第二方面，提供了一种终端设备，如图13至图15所示，该终端设备包括中框10、主板20、后盖30、显示屏40、电池50和上述的摄像头组件(图中不妨记为摄像头组件60)，其中，如图13所示，主板20、电池50和摄像头组件60均安装在中框10上，如图14所示，显示屏40安装在中框10的第一表面上，如图15所示，后盖30安装在中框10的第二表面上，第一表面与第二表面相对，主板20分别与显示屏40、电池50和摄像头组件60电性连接。
其中，中框10是终端设备的主框架，用于承载终端设备的零部件，例如，主板20、电池50、摄像头组件60、后盖30和显示屏40可以都安装在中框10上。
本申请实施例所示的方案，如图13所示，主板20可以安装在中框10的顶部位置处，电池50安装在中框10的中部位置处。摄像头组件60可以安装在主板20上，也可以安装在中框10上。而为了降低终端设备的厚度，摄像头组件60可以安装在中框10上，具体的，如图13所示，主板20上可以设置有与摄像头组件60相匹配的安装口201，摄像头组件60可以位于安装口201中，并安装在中框10上。
如图14和图15所示，显示屏40和后盖30分别安装在中框10的两个相对的表面上，例如，对于手机和平板电脑等而言，显示屏40可以安装在中框10的前面，后盖30可以安装在中框10的背面。
在电性连接关系上，主板20分别与显示屏40、电池50和摄像头组件60电性连接，电池50分别与显示屏40和摄像头组件60电性连接，用于向显示屏40和摄像头组件60供电。
本发明实施例提供的技术方案带来的有益效果是：
本发明实施例中，终端设备的摄像头组件，可以包括镜头光学器件和致动部件，其中：所述致动部件包括两个活动块、位于每个活动块两侧的固定支架和多个电控伸缩件；所述镜头光学器件位于所述两个活动块之间，分别与两个活动块相固定；每个活动块分别通过弹性件悬空式安装在所述固定支架上；每个活动块与两侧的固定支架之间分别连接有所述电控伸缩件。这样，当使用具备该摄像头组件的终端设备进行拍照时，终端设备的处理器可以基于终端设备抖动时产生的位置变化情况和旋转情况，通过控制电控伸缩件的伸缩推动或者拉动活动块运动，使活动块可以带动镜头光学器件在空间中进行旋转，这种调整镜头光学器件的致动部件，其致动效果较好，从而提高了终端设备在拍照过程中的防抖效果。

具体实施方式
本发明实施例提供了一种摄像头组件，该摄像头组件可以是独立的终端设备，例如，可以是一个独立的照相机等，摄像头组件还可以是具有拍照功能的终端设备的零部件，例如，可以是智能手机、平板电脑等的零部件。
如图1所示，该摄像头组件包括镜头光学器件1和致动部件2，其中：致动部件2包括两个活动块21、位于每个活动块21两侧的固定支架22和多个电控伸缩件23；镜头光学器件1位于两个活动块21之间，分别与两个活动块21相固定；每个活动块21分别通过弹性件3悬空式安装在固定支架22上；每个活动块21与两侧的固定支架22之间分别连接有电控伸缩件23。
如图2所示，镜头光学器件1可以包括反射镜11和反射镜安装座12，反射镜11可以是如图1和2所示的反射板，也可以是如图3所示的棱镜。反射镜11安装在反射镜安装座12中，反射镜安装座12位于两个活动块21之间，反射镜安装座12的相对两个侧壁分别与两个活动块21相固定。反射镜11安装在反射镜安装座12中，反射镜安装座12位于两个活动块21之间，反射镜安装座12的相对两个侧壁分别与两个活动块21相固定。其中，镜头光学器件1的反射镜安装座12还可以属于制动部件2，例如，反射镜安装座12的相对两个侧壁可以与活动块21一体成型加工。关于反射镜11、反射镜安装座12和活动块21之间的固定方式本实施例对此不做限定，能够实现三者一起运动即可，也即是，三者之间不可以发生相对运动。
如图1和图2所示，光线沿着箭头所示的入射路线进入摄像头组件中，经过镜头光学器件1的反射镜11反射后沿着箭头所示的反射路线传播，摄像头组件的其它滤光片以及感光元器件的中轴线可以位于反射路线上。
其中，活动块21是具有一定高度和宽度的部件，如图3所示，活动块21可以具有一定高度、宽度和厚度的柱状结构，在镜头光学器件1的两侧分别设置有一个活动块21，为方便描述不妨记为第一活动块21A和第二活动块21B。如图1和2所示，两个活动块21可以竖直立在两侧的固定支架22之间，如图4所示，活动块21也可以平躺在两侧的固定支架22之间。本实施例对活动块21的具体结构以及在两侧的固定支架22之间的放置不做具体限定，可以根据摄像头组件的空间布置而灵活设置。
在实施中，如图1、2和5所示，镜头光学器件1位于两个活动块21之间，并且固定在两个活动块21上，这样镜头光学器件1和两个活动块21便可以作为一个整体，活动块21运动时，镜头光学器件1也可以跟着活动块21发生同步运动。为了使活动块21运动过程中，不受相邻零部件的干涉，相应的，每个活动块21通过弹性件3悬空式安装在固定支架22上，也即是，活动块21的两侧通过弹性件3与固定支架22相固定，而且，活动块21与固定支架22之间不相接触，这样，活动块21便可以悬空活动安装在固定支架22上，且活动块21可以相对于固定支架22发生转动。
可选的，为了使每个活动块21稳固在两侧的固定支架22之间，相应的，如图1所示，每个活动块21两侧的弹性件3关于活动块21的铅垂线相对称。
在实施中，每个活动块21两侧的弹性件3的形状和结构相同，且弹性系数相等，这样，活动块21的两侧分别通过完全相同的弹性件3固定在固定支架3上，进而，在电控伸缩件23未通电的情况下，活动块21在两侧的固定支架22之间不会发生倾斜的情况，每个活动块21稳固在相固定的两个固定支架22之间，也提高了镜头光学器件1的稳固性。
可选的，由于两个活动块21和两个活动块21之间的镜头光学器件1处于悬空状态，在电控伸缩件23未通电的情况下，为了进一步提高镜头光学器件1的稳固性，相应的，致动部件2还包括弹性限位件5；弹性限位件5的两端分别固定在两个固定支架22上，弹性限位件5的中部固定在反射镜安装座12上。
在实施中，弹性限位件5的结构可以如图6所示，包括第一固定端51、第二固定端52和第三固定端53，弹性限位件5的第一固定端51固定在如图1所示的第四固定支架22D上，弹性限位件5的第二固定端52固定在如图1所示的第二固定支架22B上，弹性限位件5的第三固定端53固定在如图2所示的反射镜安装座12背对反射镜11的表面上。这样，镜头光 学器件1通过四个弹性件3和一个弹性限位件5相固定，两个活动块21和两个活动块21之间的镜头光学器件1作为一个整体，在三个位置处通过弹性件相固定和支撑，根据三角形稳定性，进而，可以提高镜头光学器件1在电控伸缩件23未通电的情况下的稳固性，避免了镜头光学器件1的晃动。
其中，弹性件3和弹性限位件5可以是弹性系数在预设数值范围的弹性部件，弹性件3和弹性限位件5的弹性系数过小，会导致活动块21和镜头光学器件1的稳定性较差，弹性系数过大，会导致活动块21和镜头光学器件1相对于固定支架22的活动性较差。弹性件3和弹性限位件5的弹性系数可以根据理论分析以及多次反复试验而定，以保证活动块21和镜头光学器件1既具有一定的稳定性，又相对于固定支架22具有一定的活动性。弹性件3可以是如图1所示的弯折的弹片，也可以是弹簧，例如，活动块21的两侧以及底部均通过弹簧安装在相邻的固定支架22上。
在实施中，固定支架22可以是固定在活动块21两侧，用于稳固活动块21的支架，例如，摄像头组件可以包括基板，固定支架22可以是固定在基板上的支架。又例如，摄像头组件可以包括基板，致动部件2包括基座，致动部件2的基座安装在基板上，支架固定在基座上，例如，如图7所示，致动部件2包括主框架24，主框架24包括两个基座241，每一个基座241设置有凹槽242，凹槽242的两个槽壁即为活动块21两侧的固定支架22，活动块21可以通过弹性件3悬空安装在基座4的凹槽242中，活动块21与凹槽242的槽壁以及槽底均不相接触。又例如，致动部件2也可以只包括一个基座，基座上设置具有一定长度的凹槽，两个活动块21和镜头光学器件1均位于凹槽中，凹槽的槽壁即为每个活动块21两侧固定支架22。关于每个活动块21两侧的固定支架22的具体结构，本实施例不做具体限定，能够实现支撑稳固活动块21即可，技术人员可以是根据终端设备的空间布局情况选择合适的固定支架。
为了使活动块21可以相对于固定支架22发生位移或者旋转，相应的，每个活动块21与两侧的固定支架22之间连接有至少两个电控伸缩件23。当电控伸缩件23发生伸缩变化时，由于固定支架22不可动，而活动块21处于悬空状态，电控伸缩件23便可以拉动或者推动与之相连的活动块21相对于固定支架22运动，例如，电控伸缩件23可以使活动块21带动镜头光学器件1在平面内进行平移或者在空间内绕着某一个轴进行旋转。
其中，电控伸缩件23是在通电状态可以发生伸长或者收缩的部件，其结构至少可以具有以下几种情况：
可选的，电控伸缩件23可以包括位于活动块21上的活动块连接端、位于固定支架22上的支架连接端和连接活动块连接端和支架连接端的伸缩杆。
在实施中，处理器可以控制伸缩杆的伸长和收缩，当处理器控制伸缩杆伸长时，伸缩杆对活动块21施加的是作用力是推力，当处理器控制伸缩杆收缩时，伸缩杆对活动块21施加的作用力是拉力。
可选的，电控伸缩件23可以包括位于活动块21上的活动块连接端、位于固定支架22上的支架连接端和连接活动块连接端和支架连接端的伸缩丝。
在实施中，处理器可以控制伸缩丝的收缩，当处理器控制伸缩丝收缩时，伸缩丝对活动块21施加的作用力是拉力。
可选的，如果电控伸缩件23包括伸缩丝，则伸缩丝也可以是绳索，这种情况下，电控伸 缩件23还可以包括电动绞车，伸缩丝可以设置在电动绞车的输出轴上，这样，当电动绞车收绳索时，绳索对活动块21产生拉力。
可选的，如果电控伸缩件23包括伸缩丝，则伸缩丝可以是形状记忆合金丝，形状记忆合金丝也可以简称为SMA(Shape Memory Alloy，形状记忆合金)丝，当处理器对电控伸缩件23通电时，其伸缩丝在通电的状态下，加热产生热量，温度升高，进而发生收缩，对活动块21产生拉力。
在伸缩丝为SMA丝的情况下，活动块连接端和支架连接端均为导电端子，其中，位于活动块21上的活动块连接端可以接地。为了节约布置空间，弹性件3可以是金属弹性件，每个弹性件3与同侧的活动块连接端电性连接，弹性件3再与摄像头组件的基板上的接地端电性连接。
其中，电控伸缩件23的伸缩丝为SMA丝的情况，结构简单，所使用的零部件较少，可以减少摄像头组件的零部件个数，节约终端设备的内部空间，有利于终端设备的轻量化和轻薄化发展。
在实施中，电控伸缩件23能够实现对活动块21施加作用力即可，关于施加的作用力属于推力还是拉力，本实施例对此不做限制，且电控伸缩件23对活动块21施加作用力的方式本实施例也不做限制。为方便介绍，下文将以电控伸缩件23的伸缩丝为SMA丝，对活动块21产生拉力的情况示例，电控伸缩件23对活动块21施加推力或者施加推力与拉力的合力的情况，与之类似，便不再一一赘述。
基于上述结构，致动部件2的电控伸缩件23发生伸缩变化时，拉动或者推动活动块21带动镜头光学器件1运动，可以用来补偿终端设备拍照时由于抖动产生的位移或者旋转。具体的，摄像头组件还可以包括处理器，其中，处理器分别与每个电控伸缩件23电性连接，用于在检测到终端设备启动拍照功能后每当达到预设周期时，获取终端设备在当前周期内的位移信息和姿态变化信息，基于位移信息和姿态变化信息，确定每个电控伸缩件23的控制电流值，基于每个电控伸缩件23的控制电流值，对电控伸缩件23进行伸缩控制。
其中，位移信息指的是终端设备在平面内位置信息的变化，例如，终端设备在某一个平面内向某一个方向某个平移量，例如，在垂直于光线轴的平面内向左平移了一毫米。姿态变化信息指的是终端设备在空间内姿态信息的变化，例如，终端设备在空间内绕着某一个轴旋转了某个角度。用户手持终端设备拍照发生的抖动使终端设备发生的变化即是终端设备的位移信息和姿态变化信息综合的结果。
其中，启动拍照功能也即是用户点击终端设备上的相机应用程序进入拍照模式。
控制电流值可以是对应一个较大电流的控制信号，也可以是对应一个较小电流的控制信号，还可以是对应零电流的控制信号。这样，进行伸缩的电控伸缩件23通入的电流可以是一个值较大的电流，不进行伸缩的电控伸缩件23通入的电流可以是一个值较小的电流或者零电流。
在实施中，处理器检测到终端设备启动拍照功能之后，可以周期性获取终端设备在当前周期限内的位移信息和姿态变化信息。终端设备中可以安装有检测部件，如陀螺仪等，检测部件可以周期性的向处理器发送终端设备在当前周期内的位移信息和姿态变化信息。或者，检测部件可以周期性的向处理器发送终端设备在当前周期内的位置信息和姿态，处理器基于 接收到的位置信息和姿态，确定终端设备在当前周期内的位移信息和姿态变化信息。之后，处理器可以是基于位移信息和姿态变化信息，确定每个电控伸缩件23的控制电流值。最后，处理器可以基于每个电控伸缩件23的控制电流值，对至少两个电控伸缩件23进行伸缩控制。下文将会详细介绍处理器具体控制致动部件2带动镜头光学器件1的旋转过程。
这样，由于旋转过程中也会产生平移变化，所以致动部件2带动镜头光学器件1在空间旋转的过程中，可以补偿终端设备的因抖动造成的平移变化和旋转变换，可见，这种致动部件2对镜头光学器件1的调整效果更好。从而，用户在使用该终端设备进行拍照的过程中，致动部件2带动镜头光学器件1旋转，既可以补偿终端设备的平移变化，又可以补偿终端设备的旋转变化，使镜头光学器件1与被拍摄景物可以处于相对静止的状态，进而可以提高终端设备拍摄照片的清晰度。
在实际应用中，由于终端设备的抖动具有不确定性，那么抖动可以使终端设备在空间内绕着任意一个轴旋转，为了使镜头光学器件1可以在空间内绕着任意旋转轴转动，相应的，镜头光学器件1只要能够绕着相互垂直的三个旋转轴发生旋转，便可以在空间内绕着任意旋转轴转动，因为空间中一个任意旋转轴都可以被分解为相互垂直的三个旋转轴。为了实现两个活动块21可以带动镜头光学器件1在绕着三个相互垂直的旋转轴(不妨记为第一旋转轴、第二旋转轴和第三旋转轴)发生旋转，相应的，可以在活动块21与固定支架22之间设置若干个电控伸缩件23，以实现镜头光学器件1绕着第一旋转轴旋转；可以在活动块21与固定支架22之间设置若干个电控伸缩件23，以实现镜头光学器件1绕着第二旋转轴旋转；可以在活动块21与固定支架22之间设置若干个电控伸缩件23，以实现镜头光学器件1绕着第三旋转轴旋转。
其中，为了更为形象的将三个旋转轴阐述出来，不妨将以图1所示的x轴代表第一旋转轴，图1所示的y轴代表第二旋转轴，图1所示的z轴代表第三旋转轴。图中，x轴、y轴和z轴的设置只是为了方便描述，并不形成具体限定。
为了节约布置空间，可以使用最少数量的电控伸缩件23来达到镜头光学器件1可以分别绕着三个旋转轴旋转的效果。一种可行的方式可以是，电控伸缩件23的伸缩丝可以倾斜设置，也即是，伸缩丝与x轴、y轴和z轴均不平行，这样，某一个电控伸缩件23的伸缩丝伸缩对活动块21施加作用力时，该作用力便可以分解到两个轴上，也即是，一个电控伸缩件23施加的合力可以分解成沿着两个轴的分力，进而，可以减少电控伸缩件23的数量。
相应的，如图1所示，每个活动块21的上部与两侧的固定支架22之间分别连接有电控伸缩件23，每个活动块21的下部与两侧的固定支架22之间分别连接有电控伸缩件23。也即是，致动部件2至少包括八个电控伸缩件23，每个活动块21上至少设置有四个电控伸缩件23。该情况下，四个电控伸缩件23在每个活动块21上的布局方式又具有多种，下面将介绍其中的几种，但是下面的电控伸缩件23的布局方式只是为了方便示例，并不形成具体限定：
其中一种可以是，如图8和9所示，每个电控伸缩件23包括活动块连接端、支架连接端和连接活动块连接端与支架连接端的伸缩丝；位于活动块21上部的活动块连接端的高度高于所在电控伸缩件23的支架连接端的高度，位于活动块21下部的活动块连接端的高度低于所在电控伸缩件的支架连接端的高度。
也即是，如图8所示，活动块连接端r的高度高于支架连接端t的高度，活动块连接端s 的高度低于支架连接端u的高度，其中，活动块连接端r位于活动块21的上部，活动块连接端r所在电控伸缩件23的支架连接端为支架连接端t，活动块连接端s位于活动块21的下部，活动块连接端s所在电控伸缩件23的支架连接端为支架连接端u。
也可以参考图9所示，活动块连接端a的高度高于支架连接端d的高度，活动块连接端b的高度低于支架连接端c的高度，其中，活动块连接端a位于活动块21的上部，活动块连接端a所在电控伸缩件23的支架连接端为支架连接端d，活动块连接端b位于活动块21的下部，活动块连接端b所在电控伸缩件23的支架连接端为支架连接端c。
其中，位于同一个固定支架22上的两个支架连接端的高度可以不做具体限定，例如，位于同一个固定支架22上的两个支架连接端相重合，也即是，位于同一个固定支架22上的两个支架连接端的高度相等，也即是，图9中的支架连接端d的高度等于支架连接端c。
又例如，在位于同一个固定支架22上的两个支架连接端中，第一支架连接端的高度高于第二支架连接端的高度，其中，第一支架连接端是与位于活动块21上部的活动块连接端属于同一电控伸缩件23的支架连接端，第二支架连接端是与位于活动块21下部的活动块连接端属于同一电控伸缩件23的支架连接端。也即是，如图9所示，支架连接端d和支架连接端c位于同一个固定支架22上，支架连接端d的高度高于支架连接端c，其中，活动块连接端a位于活动块21的上部，与活动块连接端a属于同一电控伸缩件23的支架连接端为支架连接端d，活动块连接端b位于活动块21的下部，与活动块连接端b属于同一电控伸缩件23的支架连接端为支架连接端c。
又例如，如图1所示，在位于同一个固定支架22上的两个支架连接端中，第一支架连接端的高度低于第二支架连接端的高度，其中，第一支架连接端是与位于活动块21上部的活动块连接端属于同一电控伸缩件23的支架连接端，第二支架连接端是与位于活动块21下部的活动块连接端属于同一电控伸缩件23的支架连接端。也即是，如图8所示，支架连接端t的高度低于支架连接端u，其中，活动块连接端r位于活动块21的上部，与活动块连接端r属于同一电控伸缩件23的支架连接端为支架连接端t，活动块连接端s位于活动块21的下部，与活动块连接端s属于同一电控伸缩件23的支架连接端为支架连接端u。
其中，对于如图1和图8所示的活动块21与一侧固定支架22之间的两个电控伸缩件23相交叉，且相交点处于活动块21与固定支架22之间的情况下，为了防止相交叉的两个伸缩丝在工作时发生相互干涉，相应的，对于每个活动块21与一侧固定支架22之间的两个电控伸缩件23，连接活动块21上部的电控伸缩件23的伸缩丝与连接活动块21下部的电控伸缩件23的伸缩丝不相接触。也即是，如图11所示，第一电控伸缩件231的伸缩丝与第四电控伸缩件234的伸缩丝所在的平面、第二电控伸缩件232的伸缩丝与第三电控伸缩件233的伸缩丝所在的平面相平行，且之间具有间隙，该间隙值为预设数值。这样，当第一电控伸缩件231与第四电控伸缩件234通电收缩，而第二电控伸缩件232和第三电控伸缩件233未通电收缩时，第二电控伸缩件232的伸缩丝不会干涉第一电控伸缩件231对活动块21的施加的作用力，第三电控伸缩件233的伸缩丝也不会干涉第四电控伸缩件234对活动块21的施加的作用力。
而对于图9和图10的情况，由于不存在伸缩丝相互干渉的问题，所以位于第一活动块21A上部的两个电控伸缩件23的伸缩丝、位于第一活动块21A下部的两个电控伸缩件23的伸缩丝可以位于同一个平面，记为第一平面；位于第二活动块21B上部的两个电控伸缩件23 的伸缩丝、位于第二活动块21B下部的两个电控伸缩件23的伸缩丝可以位于同一个平面，记为第二平面，第一平面与第二平面相平行。
综合图1、图2、图5、图8和图9，电控伸缩件23的分布特点可以是，每个活动块21与一侧的固定支架22之间的两个电控伸缩件23的伸缩丝相交叉，且相交点(可以是同一平面的相交点，也可以是异面的相交点)落在固定支架22上，或者，落在固定支架22与活动块21之间，或者，落在固定支架22远离活动块21的一侧。
可选的，四个电控伸缩件23在每个活动块21上的具体布局的另一种可能的方式可以是，如图10所示，位于活动块21上部的活动块连接端的高度低于所在电控伸缩件23的支架连接端的高度，位于活动块21下部的活动块连接端的高度高于所在电控伸缩件23的支架连接端的高度。
在实施中，如图10所示，活动块连接端j的高度低于支架连接端i的高度，其中，活动块连接端j位于活动块的上部，活动块连接端j所在电控伸缩件23的支架连接端为支架连接端i。活动块连接端k的高度高于支架连接端m的高度，其中，活动块连接端k位于活动块的下部，活动块连接端k所在电控伸缩件23的支架连接端为支架连接端m。
其中，图1、图2、图5、图8和图9中位于活动块21上部的电控伸缩件23的伸缩丝向下倾斜，位于活动块21下部的电控伸缩件23的伸缩丝向上倾斜，而图10中位于活动块21上部的电控伸缩件23的伸缩丝向上倾斜，位于活动块21下部的电控伸缩件23的伸缩丝向下倾斜。
需要指出的是，图8至图10所示的是其中一个活动块21与其两侧的固定支架22之间电控伸缩件23的连接示意图，另一个活动块21与其两侧的固定支架22之间电控伸缩件23的连接示意图类似，便不再示意。
为方便处理器对电控伸缩件23的控制，相应的，如图1、2、5、8至11所示，对于每一个活动块21，活动块21两侧的电控伸缩件23相对称，例如，如图11所示，第一电控伸缩件231和第四电控伸缩件234关于y轴相对称，第二电控伸缩件232和第三电控伸缩件233关于y轴相对称。活动块21上部分别与两侧的固定支架22相连的电控伸缩件23的伸缩丝所在的平面与活动块21下部分别与两侧的固定支架22相连的电控伸缩件23的伸缩丝所在的平面相平行，也即是，如图11所示，第一电控伸缩件231、第四电控伸缩件234所在的平面与第二电控伸缩件232、第三电控伸缩件233所在的平面相平行。
在电控伸缩件23的伸缩丝为SMA丝的情况下，活动块21与固定支架22之间的四个SMA丝交叉设置，也即是，如图1、2、5、8和图11所示的电控伸缩件23的SMA丝的布局方式，既能够较好的控制镜头光学器件1的旋转，又可以节约布置空间。这是因为，SMA丝的变形量通常较小，为了在不损坏SMA丝的情况下提高其变形量，那么需要SMA丝足够的长，在相同的占空空间情况下，与图9和10相比，图1、2、5、8和图11中SMA丝的布局方式，SMA丝的长度比较长，进而，图1、2、5、8和图11所示的电控伸缩件23的SMA丝的布局方式既可以较好的控制镜头光学器件1的旋转，又可以节约布置空间。
需要指出的是，技术人员可以根据实际的空间面积和想要达到的效果灵活选择一种合适的电控伸缩件23的布局方式，图中所示的电控伸缩件23的布局方式只是示例，并不构成具体限定。
以上是关于摄像头组件的结构介绍，下面将详细介绍，通过上述结构实现镜头光学器件 1旋转的过程：
首先，介绍一下镜头光学器件1分别绕着x轴、y轴和z轴旋转的原理：
为方便介绍，如图11所示，不妨将两个活动块21分别记为第一活动块21A和第二活动块21B，第一活动块21A两侧的固定支架22分别记为第一固定支架22A、第二固定支架22B、第三固定支架22C和第四固定支架22D，其中，第一活动块21A和第一固定支架22A之间的电控伸缩件23分别记为第一电控伸缩件231和第二电控伸缩件232，第一活动块21A和第二固定支架22B之间的电控伸缩件23分别记为第三电控伸缩件233和第四电控伸缩件234，第二活动块21B与第三固定支架22C之间的电控伸缩件23分别记为第五电控伸缩件235和第六电控伸缩件236，第二活动块21B与第四固定支架22D之间的电控伸缩件23分别记为第七电控伸缩件237和第八电控伸缩件238。
当第一电控伸缩件231、第三电控伸缩件233、第五电控伸缩件235和第七电控伸缩件237通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着x轴按照第一个方向旋转，其中，第一个方向可以是顺时针和逆时针中的一种。当第二电控伸缩件232、第四电控伸缩件234、第六电控伸缩件236和第八电控伸缩件238通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着x轴按照与第一个方向相反的第二方向旋转。
当第三电控伸缩件233、第四电控伸缩件234、第五电控伸缩件235和第六电控伸缩件236通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着y轴按照第一个方向旋转，其中，第一个方向可以是顺时针和逆时针中的一种。当第一电控伸缩件231、第二电控伸缩件232、第七电控伸缩件237和第八电控伸缩件238通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着y轴按照与第一个方向相反的第二方向旋转。
当第一电控伸缩件231、第四电控伸缩件234、第六电控伸缩件236和第七电控伸缩件237通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着z轴按照第一个方向旋转，其中，第一个方向可以是顺时针和逆时针中的一种。当第二电控伸缩件232、第三电控伸缩件233、第五电控伸缩件235和第八电控伸缩件238通电时，其上的伸缩丝发生收缩，使得两个活动块21带动镜头光学器件1绕着z轴按照与第一个方向相反的第二方向旋转。
上述是镜头光学器件1绕着x轴、y轴或者z轴中的任意一个轴旋转的情况，而如果实际旋转轴与上述三个坐标轴都不平行，可以将该实际旋转轴分解为在三个坐标轴的分量，使镜头光学器件1绕着x轴、y轴和z轴旋转中的至少一个轴旋转。或者，可以控制电控伸缩件23的通电量的不同，实现镜头光学器件1可以绕着xyz空间坐标系下任一个轴旋转。
其中，需要指出的是，为了防止镜头光学器件1绕着某一个轴旋转的过程中，未通电的电控伸缩件23对通电的电控伸缩件23产生干涉的问题，相应的，在未通电的状态下，电控伸缩件23的伸缩丝可以处于松弛状态。
另外，又为了防止电控伸缩件23突然通电导致镜头光学器件1旋转速度比较快，相应的，当处理器检测到终端设备进行拍照处理，并且终端设备的防抖功能处于开启状态下时，可以控制摄像头组件的供电部件向所有的电控伸缩件23进行预充电，向所有电控伸缩件23通入一个小电流，当需要某几个电控伸缩件23工作时，处理器再控制控制摄像头组件的供电部件 向这几个电控伸缩件23通入大电流。例如，处理器通过控制摄像头组件的供电部件向所有的电控伸缩件23进行预充电时，每个电控伸缩件23的SMA丝通入1安培的电流；当需要第一电控伸缩件321的SMA丝收缩时，处理器通过控制摄像头组件的供电部件向第一电控伸缩件231的SMA丝通入10安培的电流。
这样，不工作的电控伸缩件23可以对工作的电控伸缩件23产生一定的阻力，防止出现镜头光学器件1突然发生旋转，而出现补偿过度的情况。
以上是关于镜头光学器件1绕着旋转轴实现旋转的过程，下面将详细介绍具体的控制镜头光学器件1绕某一个旋转轴旋转的过程：
由上述所述，摄像头组件还包括处理器，处理器分别与每个电控伸缩件23电性连接，处理器的具体控制过程可以按照如图11所示的流程执行：
在步骤1201中，处理器在检测到终端设备启动拍照功能后每当达到预设周期时，获取终端设备在当前周期内的位移信息和姿态变化信息。
其中，如上述所述，位移信息是终端设备在平面内位置信息的变化，姿态变化信息是终端设备在空间发生的旋转变化，例如，绕着某一个旋转了一定角度。终端设备的抖动具有不确定性，抖动量是位移信息和姿态变化信息的综合作用的结果。
在步骤1202中，处理器确定位移信息在预设的第一方向上的第一位移分量、在预设的第二方向上的第二位移分量和在预设的第三方向上的第三位移分量，并确定姿态变化信息在预设的第一旋转轴上的第一旋转角度分量、在预设的第二旋转轴上的第二旋转角度分量和在预设的第三旋转轴上的第三旋转角度分量。
其中，第一方向、第二方向、第三方向相互垂直，第一旋转轴、第二旋转轴和第三旋转轴相互垂直，第一方向与第一旋转轴垂直，第二方向与第二旋转轴垂直，第三方向与第三旋转轴垂直。
例如，如果以三维坐标系统中的x轴为第一旋转轴，y轴为第二旋转轴，z轴为第三旋转轴，相应的，第一方向是y轴正向或者z轴正向，第二方向是x轴正向或者z轴正向，第三方向是x轴正向或者y轴正向，又根据第一方向、第二方向和第三方向三者相互垂直，故如果第一方向为沿着y轴的正向，则第三方向为沿着x轴的正向，第二方向为沿着z轴的正向。
其中，第一位移分量、第二位移分量和第三位移分量是矢量具有正负，正负表示平移方向，例如，第一方向上的第一位移分量要么是沿着第一方向，要么是沿着第一方向的反向。同样，第一旋转角度分量、第二旋转角度分量和第三旋转角度分量也具有正负，正负表示旋转方向，例如，第一旋转轴上的第一旋转角度分量要么是顺时针绕着第一旋转轴的角度，要么是逆时针绕着第一旋转轴的角度。
在实施中，如果终端设备在第一方向上发生平移，则镜头光学器件1需要绕着垂直于第一方向的轴旋转，才可以补偿终端设备在第一方向上的平移。例如，终端设备在y轴方向上发生平移，则镜头光学器件1需要绕着x轴旋转。而具体绕着x轴是顺时针旋转还是逆时针旋转，需要根据终端设备在y轴上的位移分量的正值还是负值而定。
在步骤1203中，处理器基于第一位移分量和第一旋转角度分量，确定在第一旋转轴上的第一补偿旋转角度，基于第二位移分量和第二旋转角度分量，确定在第二旋转轴上的第二补偿旋转角度，基于第三位移分量和第三旋转角度分量，确定在第三旋转轴上的第三补偿旋转角度。
其中，旋转角度与补偿旋转角度互为相反，两者方向相反，数值相等，例如，旋转角度为绕着旋转轴进行顺时针旋转的角度，补偿旋转角度为绕着该旋转轴进行逆时针旋转的角度。
在实施中，处理器根据第一位移分量确定对应的第一位移旋转角度，再对第一位移旋转角度与第一旋转角度分量进行矢量运算，矢量运算之后对得到的角度取相反数，得到在第一旋转轴上的第一补偿旋转角度。例如，如果两者的旋转方向一致则相加，如果两者的旋转方向相反则相减，这样矢量计算之后，可以得到角度β，然后处理器将负β确定为补偿旋转角度，这样便可以得到在第一旋转轴上的第一补偿旋转角度。同样，处理器根据第二位移分量确定对应的第二位移补偿旋转角度，再对第二位移补偿旋转角度与第二旋转角度分量进行矢量运算，得到在第二旋转轴上的第二补偿旋转角度。处理器根据第三位移分量确定对应的第三位移补偿旋转角度，再对第三位移补偿旋转角度与第三旋转角度分量进行矢量运算，得到在第三旋转轴上的第三补偿旋转角度。
在步骤1204中，处理器基于第一补偿旋转角度、第二补偿旋转角度和第三补偿旋转角度，确定每个电控伸缩件23的控制电流值，基于每个电控伸缩件23的控制电流值，对电控伸缩件23进行伸缩控制。
其中，再次参考图11，以x轴表示第一旋转轴、y轴表示第二旋转轴、z轴表示第三旋转轴示例。
在实施中，如果第一补偿旋转角度不为零，则处理器通过致动部件2控制镜头光学器件1绕着第一旋转轴旋转第一补偿旋转角度，具体的，处理器可以通过控制摄像头组件的供电部件，向第一电控伸缩件231、第三电控伸缩件233、第五电控伸缩件235和第七电控伸缩件237通入用于发生伸缩的电流，或者，向第二电控伸缩件232、第四电控伸缩件234、第六电控伸缩件236和第八电控伸缩件238通入用于发生伸缩的电流，具体示第一补偿旋转角度的方向而定。同样，如果第二补偿旋转角度不为零，则处理器通过致动部件2控制镜头光学器件1绕着第二旋转轴旋转第二补偿旋转角度，具体的，处理器可以通过控制摄像头组件的供电部件，向第三电控伸缩件233、第四电控伸缩件234、第五电控伸缩件235和第六电控伸缩件236通入用于发生伸缩的电流，或者，向第一电控伸缩件231、第二电控伸缩件232、第七电控伸缩件237和第八电控伸缩件238通入用于发生伸缩的电流，具体示第二补偿旋转角度的方向而定。如果第三补偿旋转角度不为零，则处理器通过致动部件2控制镜头光学器件1绕着第三旋转轴旋转第三补偿旋转角度，具体的，处理器通过控制摄像头组件的供电部件，向第一电控伸缩件231、第四电控伸缩件234、第六电控伸缩件236和第七电控伸缩件237通入用于发生伸缩的电流，或者，向第二电控伸缩件232、第三电控伸缩件233、第五电控伸缩件235和第八电控伸缩件238通入用于发生伸缩的电流，具体示第三补偿旋转角度的方向而定。
例如，可以针对第一电控伸缩件231、第三电控伸缩件233、第五电控伸缩件235和第七电控伸缩件237的SMA丝发生收缩示例，处理器可以通过控制摄像头组件的供电部件向第一电控伸缩件231通入10安培的电流，向第二电控伸缩件232通入1安培的电流，向第三电控伸缩件233通入10安培的电流，向第四电控伸缩件234通入1安培的电流，向第五电控伸缩件235通入10安培的电流，向第六电控伸缩件236通入1安培的电流，向第七电控伸缩件237通入10安培的电流，向第八电控伸缩件238通入1安培的电流。
在本公开实施例中，终端设备的摄像头组件，可以包括镜头光学器件和致动部件，其中：所述致动部件包括两个活动块、位于每个活动块两侧的固定支架和多个电控伸缩件；所述镜头光学器件位于所述两个活动块之间，分别与两个活动块相固定；每个活动块分别通过弹性件悬空式安装在所述固定支架上；每个活动块与两侧的固定支架之间分别连接有所述电控伸缩件。这样，当使用具备该摄像头组件的终端设备进行拍照时，终端设备的处理器可以基于终端设备抖动时产生的位置变化情况和旋转情况，通过控制电控伸缩件的伸缩推动或者拉动活动块运动，使活动块可以带动镜头光学器件在空间中进行旋转，这种调整镜头光学器件的致动部件，其致动效果较好，从而提高具备该致动部件的终端设备的防抖效果。
本公开实施例还提供了一种终端设备，该终端设备可以是手机、平板电脑和照相机等，如图13至图15所示(附图可以以手机示例)，该终端设备可以包括中框10、主板20、后盖30、显示屏40、电池50和上述的摄像头组件(图中不妨记为摄像头组件60)，其中，如图13所示，主板20、电池50和摄像头组件60均安装在中框10上，如图14所示，显示屏40安装在中框10的第一表面上，如图15所示，后盖30安装在中框10的第二表面上，第一表面与第二表面相对，主板20分别与显示屏40、电池50和摄像头组件60电性连接。
在实施中，中框10是终端设备的主框架，用于承载终端设备的零部件，主板20、电池50、摄像头组件60、后盖30和显示屏40可以都安装在中框10上。例如，对于手机而言，通常情况下，如图13所示，主板20可以安装在中框10的顶部位置处，电池50安装在中框10的中部位置处。需要指出的是，主板20和电池50在中框10上的安装位置，可以根据终端设备内部的实际布局情况而灵活设定，本实施例对其安装位置不做具体限定。
终端设备的摄像头组件60可以安装在主板20上，也可以安装在中框10上，由于主板20具有一定的厚度，摄像头组件60具有一定的高度，如果摄像头组件60直接安装在主板上，会增加终端设备的厚度。那么，为了降低终端设备的厚度，摄像头组件60可以安装在中框10上，具体的，如图13所示，主板20上可以设置有与摄像头组件60相匹配的安装口201，摄像头组件60可以位于安装口201中，并安装在中框10上，例如，中框10上设置有用于安装摄像头组件60的支架，该支架可以位于安装口201中，这样，摄像头组件60安装在支架上，支架位于安装口201中。需要指出的是，摄像头组件60在终端设备内部的安装方式以及安装位置，可以根据终端设备内部的具体布局方式而灵活设定，本实施例对此不做限定。
如图14和图15所示，显示屏40和后盖30分别安装在中框10的两个相对的表面上，例如，显示屏40安装在中框10的第一表面上，后盖30安装在中框10的第二表面上，其中，第一表面与第二表面相对，例如，对于手机和平板电脑等而言，显示屏40可以安装在中框10的前面，后盖30可以安装在中框10的背面。
在电性连接关系上，主板20分别与显示屏40、电池50和摄像头组件60电性连接，电池50分别与显示屏40和摄像头组件60电性连接，用于向显示屏40和摄像头组件60供电。
该终端设备的摄像头组件如上述所述，可以包括镜头光学器件和致动部件，其中：所述致动部件包括两个活动块、位于每个活动块两侧的固定支架和多个电控伸缩件；所述镜头光学器件位于所述两个活动块之间，分别与两个活动块相固定；每个活动块分别通过弹性件悬空式安装在所述固定支架上；每个活动块与两侧的固定支架之间分别连接有所述电控伸缩件。这样，当使用具备该摄像头组件的终端设备进行拍照时，终端设备的处理器可以基于终端设 备抖动时产生的位置变化情况和旋转情况，通过控制电控伸缩件的伸缩推动或者拉动活动块运动，使活动块可以带动镜头光学器件在空间中进行旋转，这种调整镜头光学器件的致动部件，其致动效果较好，从而提高具备该致动部件的终端设备的防抖效果。
以上所述仅为本发明一个实施例，并不用以限制本申请，凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的保护范围之内。
