通讯单元14，还用于根据环境光强度和屏幕当前的标准亮度选择性地发送环境光强度给主设备，以使主设备调节屏幕的亮度至与环境光强度相对应的标准亮度。具体地，通讯单元14用于将环境光强度和屏幕当前的标准亮度进行比较，以判断环境光强度和屏幕当前的标准亮度对应的标准光照强度之间的差值是否达到预设的差值，若屏幕发光且环境光强度与屏幕当前的标准亮度对应的标准光照强度之间的差值达到预设的差值时，启动通讯单元14以发送环境光强度给主设备，反之，关闭通讯单元14。
请参看图9，其为第二实施例的亮度调节装置10’的示意框图。第二实施例提供的亮度调节装置10’与第一实施例的亮度调节装置10的差异在于：增加了计时单元15以及通讯单元14’与通讯单元14的功能不同。计时单元15用于对环境光发送的时间进行计时。通讯单元14’用于若屏幕发光、环境光强度与屏幕当前的标准光照强度之间的差值达到预设的差值、且计时时间达到预设时间，发送环境光强度给主设备20。
请参看图10，为主设备20的示意框图。主设备20还包括设置单元22、匹配单元23以及调节单元24。设置单元22用于响应用户操作设置屏幕的标准亮度以及标准光照强度。匹配单元23用于根据环境光强度获取与环境光强度匹配的标准亮度。调节单元24将屏幕的亮度调整至匹配的标准亮度，并发送标准亮度给亮度调节装置10。优选地，主设备20第一次使用时，屏幕的标准亮度由用户设置，主设备20在设置标准亮度时，还相应设置了的标准光照强度。在一些可行的实施例中，用户也可以在使用过程中进行设置。
本领域普通技术人员可以意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，能够以电子硬件、计算机软件或者二者的结合来实现，为了清楚地说明硬件和软件的可互换性，在上述说明中已经按照功能一般性地描述了各示例的组成及步骤。这些功能究竟以硬件还是软件方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
所属领域的技术人员可以清楚地了解到，为了描述的方便和简洁，上述描述的主设备和单元的具体工作过程，可以参考前述方法实施例中的对应过程，在此不再赘述。
在本申请所提供的几个实施例中，应该理解到，所揭露的主设备和方法，可以通过其它的方式实现。例如，以上所描述的装置实施例仅仅是示意性的，例如，所述单元的划分，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式，例如多个单元或组件可以结合或者可以集成到另一个系统，或一些特征可以忽略，或不执行。另外，所显示或讨论的相互之间的耦合或直接耦合或通信连接可以是通过一些接口、装置或单元的间接耦合或通信连接，也可以是电的，机械的或其它的形式连接。
所述作为分离部件说明的单元可以是或者也可以不是物理上分开的，作为单元显示的部件可以是或者也可以不是物理单元，即可以位于一个地方，或者也可以分布到多个网络单元上。可以根据实际的需要选择其中的部分或者全部单元来实现本发明实施例方案的目的。
另外，在本发明各个实施例中的各功能单元可以集成在一个处理单元中，也可以是各个单元单独物理存在，也可以是两个或两个以上单元集成在一个单元中。上述集成的单元既可以采用硬件的形式实现，也可以采用软件功能单元的形式实现。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到各种等效的修改或替换，这些修改或替换都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。
