具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明作进一步详细描述。
可以理解的是，此处描述的具体实施例和附图仅仅用于解释本发明，而非对本发明的限定。
可以理解的是，在不冲突的情况下，本发明的各实施例及实施例中的各特征可相互组合。
可以理解的是，为便于描述，本发明的附图中仅示出了与本发明实施例相关的部分，而与本发明实施例无关的部分未在附图中示出。
在一些相关技术中，需要用摄像头采集显示屏的局部区域显示的图像。
例如，在电子试卷的评分过程中，显示屏显示电子试卷供人评分，同时需要摄像头采集试卷人名处的图像，以通过图像分析确定该试卷对应的人，将人与分数匹配。
再如，对地铁上的显示屏、公交车上的显示屏、广告显示屏等设置在公共场所的显示屏，为保证其显示的内容的正确性，可用摄像头采集显示屏一个角部显示的图像(如预先加在图像该位置的特定二维码)，以通过分辨该位置的图像是否正确(如是否为特定二维码)，确定显示屏是否还在正常显示(如是否故障关机、是否花屏等)，以及显示的具体内容是否正确等。
当然，应当理解，需要采集显示屏的局部区域显示的图像的具体应用，并不限于以上的例子。
参照图1，在一些相关技术中，在设置好显示屏19后，可预先将摄像头(即图像采集单元11)设置在距显示屏19较远的特定位置处，并对准显示屏19中希望被采集图像的区域，调焦并进行拍摄，待取得显示图像后，再行通过后期的图像处理，如图片剪贴方式获得所想要的局部/全局图像。
但是，以上方式需要预先根据显示屏的位置设置好摄像头，并进 行调焦，操作麻烦。
而且，若在设置好摄像头后，显示屏因某些原因发生旋转、位移等时，会造成摄像头拍摄的位置不正确，或对焦不再准确等问题，从而无法准确采集到图像，故需要相应再次调整摄像头的位置，操作麻烦；进一步的，很多情况下，无法保证在显示屏旋转、位移后都能及时的调整摄像头(例如，对设于许多公共场所的大量显示屏，显然不可能随时都有专人对其进行调整)，从而可能导致摄像头长时间无法采集到正确的图像。
另外，由于以上方式中，摄像头与显示屏之间的距离较远，故很可能有人、物等进入摄像头与显示屏之间的区域，遮挡摄像头的拍摄路径，这同样会造成摄像头无法采集到所需的图像。
第一方面，参照图2至图10，本发明实施例提供一种图像采集组件。
本发明实施例的图像采集组件用于设置在显示屏19上，使其中的图像采集单元11对准显示屏19的显示面的指定局部区域，并采集该局部区域显示的图像。
其中，显示屏19是可实现图像显示功能的产品，其具有用于进行显示的显示面。例如，显示屏19整体可为板状结构，板状结构的两个主要相对侧面中，有至少一个侧面设有显示面。
本发明实施例中，对图像采集组件所适用的显示屏19的具体类型不作限定，例如该显示屏19可为液晶显示面板(LCD)、有机发光二极管(OLED)显示面板、显示器、电子纸、手机、平板电脑、电视机、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品。
在一些实施例中，本发明实施例的图像采集组件可用于设置在公共场所中的显示屏19。
即，本发明实施例的图像采集组件特别适用于设置在公共场所的显示屏19中，例如地铁上的显示屏、公交车上的显示屏、广告显示屏 等。
本发明实施例的图像采集组件包括：贴合单元，用于贴合在显示屏19的显示面上；与贴合单元连接的图像采集单元11，用于采集贴合单元所在位置的显示面的图像。
其中，贴合单元是指能通过任何方式“贴合(例如吸附)”在显示屏19的显示面上的结构。
在一些实施例中，本发明实施例的图像采集组件用于显示面为光滑面的显示屏19，进一步用于显示面为平面的显示屏19。
显然，“贴合”通常在光滑面上更容易实现，尤其在平面上更容易实现，故本发明实施例的图像采集组件特别适用于具有光滑的显示面(进一步具有平面的显示面)的显示屏19。
当然，如果显示屏19的显示面为曲面，或者显示面是可弯折变形的，从而可能变形为各种不同形状，也是可行的。
图像采集单元11是指任何能实现图像采集功能的器件，例如是拍摄连续画面的摄像头，或者是间隔拍摄单独图像的相机等。
本发明实施例中，图像采集单元11连接贴合单元，从而当贴合单元贴合在显示屏19的显示面上时，图像采集单元11可拍摄到贴合单元所在位置的显示面所显示的图像。
本发明实施例的图像采集组件包括相互连接的贴合单元和图像采集单元11，且贴合单元能贴合在显示屏19的显示面的任意所需位置处，从而图像采集单元11可采集贴合单元所在位置(即任意所需位置)的显示面显示的图像。
可见，将贴合单元贴合在显示屏19的显示面需要被采集图像的位置，也就相当于将图像采集单元11(如摄像头)设置在所需位置，故图像采集单元11可直接采集图像，而不用单独设置图像采集单元11和调焦等，操作简便。
同时，当显示屏19发生旋转、位移等时，贴合单元和图像采集单元11自然随之发生相同的旋转、位移，图像采集单元11与显示屏19 的相对位置不变，故图像采集单元11仍可自然对准显示屏19中需要采集图像的区域，且保证对焦准确，不需要人为调整图像采集单元11，操作简便，并可保证随时采集到正确的图像。
另外，由于图像采集单元11是通过贴合单元直接连接在显示屏19上的，故其与显示屏19间的距离很短，通常不会有人、物等进入图像采集单元11与显示屏19之间，不会影响拍摄。
在一些实施例中，贴合单元包括：内有空腔21的壳体2，壳体2具有与空腔21连通的贴合口211；当壳体2以贴合口211朝向显示面的方式设置在显示面上时，显示面能气密封的封闭贴合口211；位于空腔21中的移动结构3，移动结构3能在第一位置与第二位置间移动，且移动结构3在移动过程中其外侧面与壳体2内侧间能保持气密封；第二位置为空腔21中相对第一位置更远离贴合口211的位置。
参照图4至图6，作为本发明实施例的一种方式，以上贴合单元可包括内有空腔21的(即中空的)壳体2，该壳体2具有与内部空腔21连通的“贴合口211”。而且，该壳体2的贴合口211的边沿(或者说贴合口211的“外圈”)的形状是与对应的显示屏19的显示面形状匹配的，例如，参照图4至图6，若显示面为平面，则壳体2的贴合口211的边沿也是位于一个平面中的。由此，当壳体2以贴合口211朝向显示面的方式设置在显示面上(即贴合口211“顶在”显示面上)时，壳体2的贴合口211的边沿各位置均与显示面接触，从而该贴合口211被显示面“封闭”，形成气密封的结构。
同时，壳体2中还设有可在远离或接近该贴合口211的方向上往复移动的移动结构3，例如是在垂直于显示面的方向上移动的结构；而且，在该移动结构3的移动过程中，其外侧面能保持与壳体2的内侧间的气密封。
由此，参照图3，在移动结构3位于较接近贴合口211(参照图3，与贴合口间的距离为X1)的第一位置(释放位置)时，可使壳体2的贴合口211“顶在”显示面上并被显示面封闭；之后，参照图5，使移 动结构3移动至较远离贴合口211(参照图5，与贴合口间的距离为X2)的第二位置(贴合位置)。由于壳体2与显示面之间，以及壳体2与移动结构3之间均保持气密封，故以上移动过程中，不会有气体进入由显示面、壳体2、移动结构3限定的封闭空间(空腔21的一部分)中，因此，随着移动结构3的移动，以上空间逐渐扩大，其中的气压逐渐降低，最终壳体2会因该空间与外界环境间的气压差而被“压在”或“吸附在”显示面上，也就是贴合单元贴合在显示面上。
可见，对以上形式的贴合单元，只要将壳体2的贴合口211顶在显示面上，并使移动结构3从第一位置运动至第二位置，即可自然完成贴合过程，操作简便。
当然，以上壳体2和移动结构3的具体形状是多样的。例如，壳体2可参照图2、图3等基本为“筒状”，故其中的空腔21也基本为“柱状(如圆柱状、棱柱状等)”；而移动结构3则可在该“筒状”中前后滑动，类似于“活塞”。
在一些实施例中，图像采集单元11设于空腔21内，用于通过贴合口211采集显示面的图像。
参照图2至图7，作为本发明实施例的一种方式，图像采集单元11可以就是设于以上壳体2的空腔21中的，从而，其需要通过以上贴合口211才能采集到显示面显示的图像。
以上方式一方面可使图像采集组件整体的形状规整(就是壳体2的外形)，节约图像采集组件所占的空间；另一方面，还可使图像采集单元11位于壳体2内，起到一定的保护作用。
当然，若图像采集单元11通过其它方式连接壳体2(贴合单元)也是可行的。例如，图像采集单元11也可连接在壳体2的侧面上，从而位于空腔21之外。
在一些实施例中，图像采集单元11固定连接在移动结构3上。
参照图2至图6，作为本发明实施例的一种方式，当图像采集单元11位于壳体2内时，其可以是设置在以上移动结构3上的，从而图像采集单元11会随着移动结构3的移动而运动。
例如，作为本发明实施例的一种方式，可以是预先设定图像采集单元11的焦距，从而保证当移动结构3处于第二位置(贴合位置)时，图像采集单元11的焦点正好位于贴合口211处，也就是正好位于显示面上。由此，只要完成了贴合操作，也就相当于同时自动完成了图像采集单元11的对焦，可进一步的简化操作。
在一些实施例中，图像采集单元11包括驱动线路板111和从驱动线路板111一侧凸出的镜头112。
移动结构3包括相互连接的第一移动件31和第二移动件32，第一移动件31具有开口311，且位于第二移动件32靠近贴合口211一侧。
驱动线路板111夹设在第一移动件31与第二移动件32之间，镜头112穿过第一移动件31的开口311。
参照图2、图3，作为本发明实施例的一种方式，图像采集单元11具体可包括镜头112，镜头112中包括镜片等，用于形成获取图像的光路；而镜头112设于板状的驱动线路板111上，驱动线路板111上设有用于驱动镜头112工作的各种电路和电子器件，以实现图像采集，同时也起到支撑镜头112的作用。
当然，参照图8、图10，图像采集单元11还可连接(如具体是驱动线路板111连接)引线113等，用于为图像采集单元11供电，以及将图像采集单元11采集到的图像信号输出。
相应的，参照图2、图3，移动结构3则包括第一移动件31、第二移动件32两个移动件，该两个移动件可均为板状且可相互连接，从而可将以上图像采集单元11的驱动线路板111“夹持固定”在两个移动件之间；同时，移动结构3中较靠近贴合口211的第一移动件31上还设有开口311，用于供图像采集单元11的镜头112穿过，以采集显示面的图像。
参照图2、图3，具体可通过多个(图中以四个为例)穿过第一移动件31和第二移动件32的螺钉(实际还穿过驱动线路板111)的螺钉，将两个移动件连接在一起。
当然，第一移动件31、第二移动件32的具体连接方式是多样的；例如，第一移动件31、第二移动件32之间也可通过卡接、粘结等其它方式连接，只要二者能连接，且将图像采集单元11的线路板固定在二者之间即可，在此不再详细描述。
在一些实施例中，第一移动件31、第二移动件32、驱动线路板111中的两者可分别设有匹配的对位凸起391和对位缺口392。
例如，参照图2、图3，作为参照图的一种方式，驱动线路板111可设有朝向第二移动件32突出的对位凸起391，而第二移动件32上设有对位缺口392，对位凸起391可卡合在对位缺口392中，从而在组装移动结构3和图像采集单元11时，只要将对位凸起391和对位缺口392相互对合即可保证组装的正确性，且还可提高结构的稳定性。
当然，虽然图2、图3中以驱动线路板111设有对位凸起391、第二移动件32设有对位缺口392为例进行说明，但若对位凸起391、对位缺口392所在的具体器件发生变化，也是可行的，在此不再详细描述。
在一些实施例中，镜头112外侧面与第一移动件31的开口311的内侧面间设有第一密封件71。
参照图2、图3，当图像采集单元11的镜头112要穿过第一移动件31上的开口311时，为避免二者之间的接触位置漏气而影响贴合(如吸附)效果，在二者之间还可设有第一密封件71(如密封圈等)。
当然，应当理解，图像采集单元11与移动结构3的具体形式以及二者之间的连接方式都是多样的，而不限于以上的例子。例如，移动结构3可就是一个与壳体2的内侧面气密封的板状的移动件，而图像采集单元11直接连接(如粘结、卡接等)在该移动件靠近贴合口211一侧。
在一些实施例中，图像采集单元11固定设置在第二位置远离贴合口211一侧；移动结构3由透明材料构成。
参照图7，作为本发明实施例的另一种方式，图像采集单元11也可以是固定设置在壳体2的空腔21中的，并位于比第二位置(即比移 动结构3)更远离贴合口211的位置(例如直接固定在壳体2的底部内侧上)，且移动结构3透明，从而图像采集单元11可“透过”透明的移动结构3采集显示面的图像。这样，图像采集单元11与贴合口211的相对位置更加固定，更有利于实现准确的对焦。
当然，应当理解，图像采集单元11如果设置在其它位置也是可行的，例如，图像采集单元11也可设在比第一位置(即比移动结构3)更靠近贴合口211处，如直接设置在壳体2的内侧面上。
当然，应当理解，以上图像采集单元11的具体连接方式也是多样的，如可卡接、粘结等，在此不再详细描述。
在一些实施例中，壳体2由不透明材料构成。
作为本发明实施例的一种方式，壳体2的材料可以是不透明的，例如，壳体2可由塑料、金属等材料构成。这样，当壳体2贴合在显示面上时，可将其所在位置(也就是希望采集图像的位置)“挡住”，避免外界看到显示面在该位置显示的图像，一方面可起到保密的作用，另一方面也避免该位置的图像对干扰显示效果，例如，该位置可显示特定的识别标记(如以上二维码)，而非常规的显示内容。
在一些实施例中，壳体2对应贴合口211的边沿设有第二密封件72。
参照图2、图3，壳体2通常是刚性材料构成的，而显示屏19的显示面通常也是刚性的，为了保证显示面能有效的封闭贴合口211，可在壳体2对应贴合口211的外沿设置第二密封件72(如硅胶垫圈)，或者说在贴合口21上“套上一圈”第二密封件72。
在一些实施例中，移动结构3外侧面与壳体2内侧面间设有第三密封件73。
为保证移动结构3在移动时能与壳体2间保持良好的气密封，故在移动结构3外侧面与壳体2内侧面之间还可设置第三密封件73(如密封圈)，例如可将第三密封件73套设在移动结构3的侧面。
当然，以上第三密封件73的具体形式应当与移动结构3的形式匹 配。例如，参照图2、图3，当移动结构3包括第一移动件31、第二移动件32，且驱动线路板111夹设在两个移动件之间时，第三密封件73相当于也套设在驱动线路板111的侧面外，例如，第三密封件73上可设有两道凹槽，分别用于供第一移动件31和驱动线路板111的边缘部分插入，以改善密封效果。
在一些实施例中，图像采集组件还包括：锁定结构，至少用于在移动结构3位于第二位置时锁定移动结构3。
在贴合单元处于贴合状态(移动结构3位于第二位置)时，移动结构3对应外界环境的一侧的气压更大，故会受到将其推向第一位置的力，而为了保证移动结构3能自动稳定第二位置以保持贴合状态，可设置锁定结构，用于将移动结构3固定在第二位置。
其中，锁定结构的具体形式是多样的，后续再详细描述。
在一些实施例中，壳体2还具有与空腔21连通的操作口212，操作口212与贴合口211位于空腔21的两相对端；贴合单元还包括操作结构4，其连接移动结构3背离贴合口211一侧，且从操作口212伸出壳体2外。
参照图2至图6，移动结构3背离贴合口211一侧(图2至图6中具体为第二移动件32背离背离贴合口211一侧)还可连接有操作结构4，该操作结构4可为参照图2至图6的操作杆等形式，其通过位于壳体2与贴合口211相对端的操作口212“伸出”壳体2之外，从而用户可抓住该操作结构4而“带动”移动结构3移动，实现贴合单元在贴合状态和释放状态间的切换，操作简便。
同时，由于存在操作口212，以上空腔21位于移动结构3远离贴合口211一侧的部分是与外界环境连通的，其中的空气不会因为移动结构3的移动而被压缩或膨胀，也不会产生压力变化。
当然，实现对移动结构3的操作的方式并不限于此。例如，也可参照图7，贴合单元中并无以上的操作结构和操作口，而是通过设在壳体2外的磁性器件吸引(相应的，移动结构3中也要包括磁性器件)，或是通过是在设壳体2内的驱动器件驱动等方式，带动移动结构3运 动，在此不再详细描述。
在一些实施例中，操作结构4位于壳体2外的位置连接锁定结构，锁定结构至少用于在移动结构3位于第二位置时与壳体2接触以锁定移动结构3。
作为本发明实施例的一种方式，可以是在以上操作结构4(如操作杆)位于壳体2外的位置连接以上锁定结构，从而锁定结构能在移动结构3位于第二位置时“卡在”壳体2上，以起到将移动结构3定位的作用。
在一些实施例中，壳体2包括与贴合口211相对的后壁22，操作口212位于后壁22上；锁定结构包括锁定件51和弹性件52；弹性件52设于后壁22与移动结构3间，当移动结构3位于第二位置时弹性件52能向移动结构3施加指向贴合口211的压力；锁定件51至少用于在移动结构3位于第二位置时与后壁22背离贴合口211一侧接触以锁定移动结构3。
参照图2至图6，作为本发明实施例的一种方式，壳体2可具有后壁22(可为参照图2、图3的可分离的后壁22，或者是与壳体2的其它位置一体的后壁22)，而以上操作口212即设于后壁22上。而且，后壁22与移动结构3之间(如后壁22与第二移动件32之间)设有弹性件52，当移动结构3位于第二位置时，弹性件52处于被压缩的状态，从而会向移动结构3施加指向贴合口211的力；而此时，锁定结构的锁定件51会受到操作结构4的拉动，被卡在后壁22上，从而阻止移动结构3向贴合口211运动，将移动结构3锁定。
在一些实施例中，弹性件52为套设在操作结构4外的弹簧。
参照图2至图6，以上弹性件52具体可以是套设在操作结构4(如操作杆)之外的弹簧，从而操作结构4可在一定程度起到对弹簧进行定位的作用，保证弹簧位置的稳定性。
在一些实施例中，锁定件51通过转轴519与操作结构4转动连接。
锁定件51具有第一接触面511和第二接触面512，第二接触面512与转轴519间的距离大于第一接触面511与转轴519间的距离，且第 二接触面512与转轴519间的距离和第一接触面511与转轴519间的距离的差，等于第一位置与第二位置间的距离。
锁定件51转动至第一接触面511与后壁22背离贴合口211一侧接触时，用于将移动结构3锁定在第一位置；锁定件51转动至第二接触面512与后壁22背离贴合口211一侧接触时，用于将移动结构3锁定在第二位置。
作为本发明实施例的一种方式，锁定件51(如把手)可通过转轴519连接操作结构4(如参照图2、图3，转轴519可穿设在锁定件31和操作结构4上的孔中，并通过螺母固定)，故锁定件51可相对操作结构4(如操作杆)转动，而当锁定件51转动至不同位置时，其通过两个不同的接触面(第一接触面511和第二接触面512)与后壁22接触，且这两个接触面与转轴519(即锁定件51与操作结构4的连接处)之间的距离不同。
由此，参照图3，可将壳体2的贴合口211“顶在”显示屏19的显示面上，此时锁定件51转动至第一接触面511与后壁22接触，由于第一接触面511与转轴519间距离较短，故转轴519距离后壁22较近，即操作结构4位于壳体2外的部分较短，位于壳体2内的部分较长，从而移动结构3被锁定在靠近贴合口211而远离后壁22的第一位置，贴合单元处于释放状态。
当需要进行贴合时，可参照图4，通过锁定件51拉动操作结构4向背离显示屏19的方向移动，带动移动结构3远离贴合口211，降低由显示面、壳体2内侧面、移动结构3限定的空间中的气体，实现贴合；同时，转动锁定件51，使其第二接触面512朝向后壁22。
之后，参照图5，释放锁定件51，在弹性件52和气压差的作用下，使锁定件51的第二接触面512与后壁22接触，由于第二接触面512与转轴519间距离较长，故也就是转轴519距离后壁22较远，操作结构4位于壳体2外的部分较长，位于壳体2内的部分较短，从而移动结构3被锁定在远离贴合口211而靠近后壁的第二位置，贴合单元进入贴合状态而被贴合在显示面上，并保持稳定，图像采集单元11可开 始采集图像。
而若要将贴合单元从显示面上取下，可再次拉动锁定件51，并将其转动至第一接触面511朝向后壁22，释放后第一接触面511自然接触后壁22，移动结构3回到第一位置，贴合单元内部与外界环境间的压力差消失，贴合单元回到释放状态，可被从第一接触面511朝向后壁22。
可见，根据以上方式，用于只要通过拉动锁定件51并进行简单的旋转，即可实现壳体2在贴合状态和释放状态间的切换，而且，贴合单元在贴合状态和释放状态都可自行保持稳定，故其操作简便。
当然，锁定结构的具体形式不限于此，其也可为其它任何能将移动结构3锁定在第二位置的结构。
在一些实施例中，贴合单元包括：用于贴合在显示面上的吸盘。
作为本发明实施例的另一种方式，贴合单元也可以就是能直接贴合在显示面上的吸盘，而图像采集单元11可连接在该吸盘上(例如连接在吸盘后的连杆上)。
当然，贴合单元的具体形式也不限于以上壳体2和吸盘的例子，其也可为其它任意能贴合在显示面上的结构。
在一些实施例中，图像采集组件还包括：卡合单元6，用于卡合连接在显示屏19上；贴合单元连接在卡合单元6上。
参照图8至图10，作为本发明实施例的一种方式，图像采集组件还可包括能卡接在显示屏19上的卡合单元6，而以上贴合单元(图中可见的为外壳2)也连接在卡合单元6(如参照图8通过两个螺钉连接)上。由此，卡合单元6可连接在显示屏19上时，也就相当于将贴合单元固定在显示屏9的显示面的特定位置，同时，贴合单元自身再贴合在该位置，从而可使贴合单元(包括与其连接的图像采集单元11)的定位更加稳固。
在一些实施例中，卡合单元6包括：夹持件61，其包括间隔设置的第一分支611和第二分支612，以及连接在第一分支611与第二分支612间的连接部613，第一分支611与第二分支612用于将显示屏19夹在二者之间，且第一分支611位于显示屏19的显示面一侧；贴合单元连接在第一分支611上。
参照图8，卡合单元6具体可包括两个分别位于显示屏19两侧的分支(第一分支611和第二分支612)，且两个分支通过连接部613连接，而贴合单元连接在其中位于显示面一侧的分支(第一分支611)上。或者说，卡合单元6整体类似一个可夹在显示屏19上的“夹子”，而贴合单元连接在夹子的一支上。
在一些实施例中，卡合单元6还包括压紧螺杆62和垫片631；第二分支612设有与压紧螺杆62匹配的螺孔6121；压紧螺杆62穿过螺孔6121，且接近第一分支611的一端连接垫片631。
参照图8，卡合单元6中还可包括压紧螺杆62，且其中对应显示屏19背侧(背离显示面一侧)的分支(第二分支612)上设有与压紧螺杆62匹配的螺孔6121，压紧螺杆62穿设在螺孔6121中，并可根据显示屏19厚度的不同而拧紧至不同的程度，从而将显示屏19夹紧在压紧螺杆62与第一分支611(也就是贴合单元)之间。其中，为了避免压紧螺杆62对显示屏19局部施加的压强过大，还可在压紧螺杆62接触显示屏19的一端连接垫片631(如硅胶垫片)。
当然，参照图8，卡合单元6中还可包括其它的结构，例如用于容纳以上垫片631的装夹件632等。
在一些实施例中，图像采集组件还包括：支架单元8，显示屏19用于设置在支架单元8上；卡合单元6与支架单元8连接。
参照图9、图10，作为本发明实施例的一种方式，图像采集组件还可包括支架单元8，而显示屏19是直接设置在该支架单元8上的。
例如，显示屏19可为广告显示屏，其被固定在支架单元8上并被支架单元8支撑，从而支架单元8与显示屏19的整体可构成一个“广告牌”。
可见，显示屏19相对支架单元8的位置是固定的；同时，卡合单元6也连接支架单元8，从而卡合单元6相对支架单元8的位置也是固定的。由此，可更有效的保证卡合单元6可能将贴合单元固定在显示屏19的特定位置。
其中，显示屏19与支架单元8的具体连接方式，以及卡合单元6与支架单元8间的具体连接方式等都是多样的。例如，可参照图9，支架单元8为围绕在显示屏19各侧面外的“外框”，而卡合单元6包括以上“夹子”式的卡合件61，且该“夹子”的连接部613通过与“外框”的一侧连接；进一步的，参照图8、图10，卡合件61还可从侧面“顶住”显示屏19，以使其与显示屏19间的定位更稳固，例如，卡合件61可通过包括以上压紧螺杆、螺孔、垫片、装夹件等的结构(未标出附图标记)连接支架单元8并“顶住”显示屏19。
当然，以上支架单元8、卡合单元6的具体形式均不限于此，在此不再详细描述。
第二方面，参照图11、图12，本发明实施例提供一种图像采集组件。
本发明实施例的图像采集组件用于设置在显示屏19上，使其中的图像采集单元11对准显示屏19的显示面的指定局部区域，并采集该局部区域显示的图像。
本发明实施例的图像采集组件特别适用于设置在公共场所的显示屏19中，例如地铁上的显示屏、公交车上的显示屏、广告显示屏等。
本发明实施例的图像采集组件包括：卡合单元6，用于卡合连接在显示屏19上；图像采集单元11，其与卡合单元6连接；卡合单元6卡合连接在显示屏19上时，图像采集单元11位于与显示屏19的显示面具有预定距离处，图像采集单元11用于采集其所在的位置的显示面的图像。
本发明实施例中，卡合单元6与图像采集单元11的相对位置是固定的，故卡合单元6被固定在显示屏19上时，也就相当于图像采集单 元11(如摄像头)被设置在相对显示屏19的特定位置处，图像采集单元11可直接采集到显示面的所需区域的图像，而不用单独设置图像采集单元11和调焦等，操作简便。
同时，当显示屏19发生旋转、位移等时，卡合单元6和图像采集单元11自然随之发生相同的旋转、位移，图像采集单元11与显示屏19的相对位置不变，故图像采集单元11仍可自然对准显示屏19中需要采集图像的区域，且保证对焦准确，从而不需要人为调整图像采集单元11，操作简便，并可保证随时采集到正确的图像。
另外，由于图像采集单元11是通过卡合单元6直接连接在显示屏19上的，故其与显示屏19间的距离很短，通常不会有人、物等进入图像采集单元11与显示屏19之间，不会影响拍摄。
在一些实施例中，卡合单元6包括：夹持件，其包括间隔设置的第一分支和第二分支，以及连接在第一分支与第二分支间的连接部，第一分支与第二分支用于将显示屏19夹在二者之间，且第一分支位于显示屏19的显示面一侧；图像采集单元11连接在第一分支上。
作为本发明实施例的一种方式，该卡合单元6也可包括以上图8所示的，由连接部和两个分支构成的“夹子”形式的夹持件，而此时图像采集单元11(不是贴合单元)直接连接在夹子对应显示面的一支上。
当然，该卡合单元6也可进一步包括以上图8所示的压紧螺杆、螺孔、垫片、装夹件等结构，在此不再详细描述。
在一些实施例中，图像采集组件还包括：支架单元8，显示屏19用于设置在支架单元8上；卡合单元6与支架单元8连接。
参照图9，作为本发明实施例的一种方式，本发明实施例的图像采集组件也可包括以上支架单元8，显示屏19可设置在支架单元8上，例如支架单元8与显示屏19一起组成“广告牌”；而卡合单元6也与支架单元8连接，以使卡合单元6与显示屏19之间的连接更稳固。
其中，卡合单元6、支架单元8的具体形式是多样的，如支架单元8可为以上“外框”等形式，而卡合单元6可通过以上图8的压紧 螺杆等结构与支架单元8连接，在此不再详细描述。
可以理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本发明的保护范围。
