本发明的较佳实施方式
如背景技术所述，移动终端上的闪光灯用作手电筒时，一般都是按照极黑暗的环境下闪光灯所能达到的照明亮度来设置驱动电流，例如智能手机的驱动电流设置为200mA，而实际应用中，很多时候闪光灯用作手电筒时，并不需要这么强的照明亮度。
本发明实施例提供了一种闪光灯用作手电筒照明功能时，自动调节手电筒照明亮度的方法，利用本发明实施例提供的技术方案，可以根据环境亮度，适当调整闪光灯的驱动电流，既能满足照明要求，又能达到降低功耗节省电量的目的，有利于提升移动终端的续航能力，提高用户体验。
下文中将结合附图对本发明的实施例进行详细说明。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互任意组合。另外，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
实施例一
本发明实施例首先提供一种照明装置，图1为本发明实施例一闪光灯照明装置的组成结构示意图，如图1所示，所述闪光灯照明装置包括光检测器11、处理器12、闪光灯驱动器13和闪光灯14，其中：
所述光检测器11，适用于根据处理器的第一指令，检测周围环境的光照强度，并将检测到的光照强度结果发送给处理器；
这里，所述第一指令用于触发光检测器检测周围环境的光照强度；
所述处理器12，适用于在用户打开闪光灯时，向光检测器发送第一指令；获取光检测器检测的光照强度结果，并根据所述光照强度结果，确定闪光灯驱动器的驱动电流的第一数值；以及向闪光灯驱动器发送第二指令，所述第二指令用于控制所述闪光灯驱动器以确定出的所述第一数值，向所述闪光灯提供驱动电流；
所述闪光灯驱动器13，适用于接收处理器发送的第二指令，根据所述第 二指令向所述闪光灯提供驱动电流；
所述闪光灯14，适用于根据闪光灯驱动器提供的驱动电流进行照明。
本发明实施例中，所述闪光灯照明装置用于移动终端，所述移动终端至少包括智能手机、平板电脑、笔记本电脑、个人数字助理、导航仪等终端设备。
这里，光检测器11可以采用各种光传感器来实现，其通过I2C等硬件总线连接移动终端的主处理器，用来实现移动终端周围环境光照强度的检测，并向主处理器传输有关检测周围环境的光照强度结果。
这里，处理器12可以是移动终端的主处理器，处理器12可选地采用周期性的方式读取光检测器检测到的光照强度结果，并根据不同的光照强度结果，实时地调整闪光灯驱动器的驱动电流。例如，当环境光照强度(即光检测器检测到的周围环境的光照强度结果)<5勒克斯(lx)时，闪光灯工作于最大照明亮度；当环境光照强度介于5lx和15lx之间时，此时的闪光灯驱动电流适当的向下减小，以减小闪光灯的照明亮度。其中lx是照度的单位，照度是反映光照强度的一种单位，照度的物理意义是照射到单位面积上的光通量，照度的单位是每平方米的流明(Lm)数，也叫做勒克斯(Lux)；环境光照强度与闪光灯亮度之间的对应关系可以通过预设的列表进行设定，处理器可以查询该列表得到闪光灯的亮度。
这里，闪光灯驱动器主要由闪光灯驱动芯片或闪光灯驱动电路(IC)组成，与移动终端主处理器间通过I2C等硬件接口相连，闪光灯驱动芯片的输出电流可以通过内部寄存器来控制；移动终端的主处理器根据环境光照强度与闪光灯亮度之间的对应关系、以及闪光灯驱动芯片内部的寄存器值与闪光灯驱动IC输出电流的关系，通过I2C等硬件接口适时配置闪光灯芯片的寄存器，调整闪光灯驱动IC的输出电流大小从而控制手电筒闪光灯的照明亮度，以实现自动调节移动终端闪光灯照明亮度的目的，使其既能满足照明要求，又能达到降低功耗节省电量的目的，提升移动终端的续航能力。
综上所述，上述实施例提供的方法可以在闪光灯用作手电筒时，根据环境光照强度实现自动调节闪光灯照明亮度的目的，从而解决闪光灯以固定亮度照明时存在的问题，即：按照极黑环境下所能达到的照明效果设置驱动电 流，在环境照明亮度较亮时，此时手电筒闪光灯并不需要如此大的亮度，造成电量的浪费，缩短了移动终端的续航时间；如果调低手电筒闪光灯的固定驱动电流，在极暗环境下手电筒闪光灯又达不到相应的照明效果。利用本发明实施例提供的技术方案，可以很好地解决上述应用中存在的问题。同时，本发明实施例提供的技术方案可以使用移动终端的通用电路设计，电路简单，性能可靠，成本低廉，便于实现。

步骤204，所述处理器向闪光灯驱动器发送第二指令；
这里，所述第二指令用于控制所述闪光灯驱动器以确定出的所述驱动电流的第一数值，向所述闪光灯提供驱动电流；
步骤205，所述闪光灯驱动器接收处理器发送的第二指令，根据所述第二指令向所述闪光灯提供驱动电流；

步骤301，检测用户的第一操作；

这里，自动调节模式和非自动调节模式可以采用选项的方式来实现，例如在本方法采用程序软件来实现时，在软件中设置闪光灯亮度调节模式，该闪光灯亮度调节模式包括自动调节和非自动调节两个选项，当用户可以将闪光灯亮度调节模式设置为自动调节，当然也可以将闪光灯亮度调节模式设置为非自动调节；当设置为自动调节时，即第一参数为yes；

这里，第一参数和第一条件以yes或no来举例，在具体实现的过程中，将不限于上述的yes或no，例如第一参数可以是0或1，当第一参数为1时，表明移动终端中闪光灯的亮度采用自动调节的模式，当第一参数为0时，表明移动终端中闪光灯的亮度不能采用自动调节的模式；第一参数为1或0的情况与第一参数为yes或no的情况非常类似，为节约篇幅，因此不再赘述。
