Description

电子设备
本申请要求申请日为2017年9月22日的中国专利申请CN201710866202.8的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及摄像头技术领域，特别涉及一种电子设备。
背景技术
目前，越来越多的电子设备，采用了双摄像头。双摄像头可显著加大摄像头的进光量，提升感光能力和照片亮度，还可有效降低噪点。
目前主流的双摄像头的功能，主要可以分为两大类：1.利用双摄像头产生立体视觉，获得影像的景深，利用景深信息进行背景虚化，物体分割，3D扫描(three-dimensional扫描，对物体进行三维扫描)，辅助对焦，动作识别等应用；2.利用左右两张不同的图片信息进行融合，以期望得到更高的分辨率，更好的色彩，动态范围等更好的图像质量或实现光学变焦这个功能。这两类双摄像头功能对于摄像头的硬件有着不同的要求，前者要求两个摄像头之间有更大的间距，这样能够得到更高的景深精度，因此前者的硬件希望两个摄像头间的距离比较远才好；而后者因需要两颗摄像头的图片叠加合成，所以在硬件设计的时候希望两个摄像头离得比较近，这样在两个图像融合的时候才不会因为相差产生更多的错误。从上可以看出，以上功能对于硬件的要求是相反的。
现有的设计由于双摄像头固定，故只能以一个功能为主要方向，即在同一个终端上只能实现上述的一种成像方法。

马达203用于在线圈通电后，通过所述伸缩部件204带动移动成像单元20移动，移动成像单元20用于在移动时带动第二支架22相对于第三支架23在第二支撑板24的滑轨上移动。
在固定成像单元21中，第二摄像头模组211以胶粘的方式固定在第四支架212中，第四支架212用于支撑第二摄像头模组211，起到了定位的作用。
第二摄像头模组211通过pin脚与第二PCB板固定连接，第二FPC213分别与第二PCB板和主板25连接。
固定成像模组以点胶方式固定于第二支撑板24上。
固定成像模组也置于第三支架23中，第三支架23还包括第二限位孔，第二摄像头模组211的摄像头设置在第二限位孔中。
第三支架23以卡接方式固定在第二支撑板24上，第三支架23从整体上保护了移动成像单元20和固定成像单元21，第一限位孔的长度要大于第二限位孔的长度，保证移动成像单元20在移动时，保证了第一摄像头模组201的摄像头有足够的移动空间。
马达203用于在线圈通电后，通过所述伸缩部件204带动移动成像单元20移动，从而使移动成像单元20移动时能接近或远离固定成像单元21。
实际使用中，电子设备包括选择景深效果模式和选择光学变焦模式的2种拍摄模式。
初始状态，移动成像单元20中的第一摄像头模组201的中心和固定成像单元21中的第二摄像头模组211的中心距离为12mm，此距离适合景深效果模式，即电子设备的默认拍摄模式为景深效果模式。
当用户在菜单上选择光学变焦模式时，拍摄模式选择单元27用于将电子设备的拍摄模式选择为光学变焦模式，控制单元26用于根据所选择的拍照模式和当前双成像单元中的摄像头模组的中心间距离控制PCB板，PCB板给马达203提供不同大小和方向的电流，电流的范围为4mA～10mA。此外。
如上，当用户选择光学变焦模式时，控制单元26控制双成像单元的两个摄像头模组靠近，具体的，马达203用于在线圈通电后受到所在磁场的电磁力，将电流转化为机械力从而发生移动，并根据PCB板所提供的电流的大小和方向，通过伸缩部件204带动移动成像单元20相对于第三支架23向固定成像单元21方向移动4mm，缩短双成像单元间的距离，实现两颗摄像头的图片叠加与合成。
在上述基础上，用户在菜单上选择景深效果模式，拍摄模式选择单元27用于将电子设备的拍摄模式选择为选择景深效果模式，控制单元26用于根据所选择的景深效果模式控制双成像单元的两个摄像头模组远离，具体的，马达203用于在线圈通电后受到所在磁场的电磁力，将电流转化为机械力从而发生移动，并根据PCB板所提供的电流的大小和方向，通过伸缩部件204带动移动成像单元20向固定成像单元21的反方向移动4mm，拉长双成像单元间的距离，实现更高的景深精度。
本实施例的电子设备，通过移动成像单元的移动来调节第一摄像头模组和第二摄像头模组间距离，使用户在同一电子设备上，能实现景深效果模式的拍摄和光学变焦模式的拍摄，从而根据用户不同的需求拍出最优效果的照 片，提高了用户体验。
实施例3
本实施例的电子设备与实施例2的电子设备基本相同，故不再赘述。主要区别是本实施例的双成像单元包括2个移动成像单元，第三支架的第一限位孔和第二限位孔的长度与实施例2中的第一限位孔的长度相同。
本实施例的电子设备，通过2个移动成像单元的移动来调节第一摄像头模组和第二摄像头模组间距离，使调节范围更大、更为灵活。
虽然以上描述了本发明的具体实施方式，但是本领域的技术人员应当理解，这仅是举例说明，本发明的保护范围是由所附权利要求书限定的。本领域的技术人员在不背离本发明的原理和实质的前提下，可以对这些实施方式做出多种变更或修改，但这些变更和修改均落入本发明的保护范围。下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施例范围之中。
