 本发明的最佳实施方式
为使本发明的目的、技术方案及优点更加清楚、明确，以下参照附图并举实施例对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
请参见图1，图1是本发明基于移动终端的双摄像头供电控制方法的较佳实施例的流程图。如图1所示，本发明实施例所述基于移动终端的双摄像头供电控制方法，包括以下步骤：
S10、预先将移动终端的前置摄像头和后置摄像头分别通过不同的开关连接到同一路供电，即前置摄像头通过第一开关、后置摄像头通过第二开关连接至同一路供电，所述第一开关和第二开关分别与中央处理器连接，均由中央处理器控制。
本发明在具体实施时，需要预先将移动终端的前置摄像头和后置摄像头分别通过不同的开关连接到同一路供电，如图2和图3所示，本发明实施例中前置摄像头通过第一开关K1、后置摄像头通过第二开关K2连接至同一路供电，所述第一开关K1和第二开关K2分别与中央处理器连接，均由中央处理器控制。
S100，预先设置默认摄像头编号，并将该默认摄像头编号存储在移动终端的存储器中；同时设置各种特定使用条件下及其对应摄像头编号，也将该对应关系存储在移动终端的存储器中。
具体地，步骤S100包括：
预先设置前置摄像头对应的摄像头编号为1，后置摄像头对应的摄像头编号为2；也就是用1表示前置摄像头，2表示后置摄像头；在移动终端出厂时预先设置默认摄像头编号为1。
本发明实施例中，除了在移动终端中设置默认摄像头编号外，考虑到有些应用只能使用指定的摄像头，比如支付宝扫码功能只使用移动终端后置摄像头；因此在移动终端中还设置各种特定使用条件下及其对应摄像头编号，所述各种特定使用条件包括移动终端厂商自己定义的特定使用条件，比如厂商定义当检测到移动终端的电池电量低于10％时只使用后置摄像头，还包括用户安装的各种应用当需要调用摄像头时应用程序本身设定的条件，比如支付宝扫码功能只使用移动终端摄像头。
其中，厂商定义的条件需要在此处记下来，其用一个文本文件进行记录，如下：
电池电量低于10％，2；
当启动蓝牙时，1。
上例的文本文件内容中，每一行表示一个厂商定义的条件及其对应的摄像头编号，比如“电池电量低于10％，2”表示当电池电量低于10％时只使用后置摄像头，“当启动蓝牙时，1”表示当启动蓝牙时只使用前置摄像头。
对于用户安装的各种应用当需要调用摄像头时应用程序本身设定的条件（比如支付宝扫码功能只使用后置移动终端摄像头），这些由应用厂商自行设定。
另外，用户也可以手动更改默认摄像头编号，并且更改后的默认摄像头编号会被存储同时替换原来的默认摄像头编号。比如，用户通过设置菜单修改默认摄像头编号为2。
其中，所述存储器为掉电不易失存储器，也就是存储器在断电条件下也能保存内容；譬如FLASH，EMMC等。
S200，当检测到用户的操作指令或其他应用启动摄像头时，先判断当前条件是否为特定使用条件，若为是则根据该特定使用条件下对应摄像头编号，对该摄像头编号对应的摄像头启动供电并打开摄像头。
具体地，当检测到摄像头被启用时，先要知道打开哪个摄像头（前置摄像头还是后置摄像头）；本发明实施例中通过获取前面提到的出厂时就保存的文本文件，对文本文件中的每一行中的条件均进行判断，如果某一行的条件符合当前移动终端的状态，则使用该行中的数字对应的摄像头；比如目前电池电量低于10％时则使用摄像头编号2对应的摄像头即后置摄像头。
在确定使用哪个摄像头后，则通过开关选择（如图2）将供电连到哪个摄像头上，本实施例中通过开关将供电连到要使用的摄像头上。
比如目前电池电量低于10％时则使用摄像头编号2对应的摄像头即后置摄像头，则将开关连到后置摄像头上，如图3所示。
S300，如果当前不是特定使用条件，则获取默认摄像头编号，对该摄像头编号对应的摄像头启动供电并打开摄像头。
本发明实施例中具体地，当文本文件中的条件都没有满足时，则获取默认摄像头对该摄像头编号对应的摄像头启动供电并打开摄像头。即通过开关选择（如图2）将供电连到哪个摄像头上，本发明实施例中通过开关将供电连到要使用的摄像头上。
比如目前默认摄像头编号为2则使用摄像头编号2对应的摄像头即后置摄像头，则将开关连到后置摄像头上，如图3所示。
由上可见，本发明提供了一种移动终端双摄像头供电控制方法，所述方法通过预先设置默认摄像头编号，并将该默认摄像头编号存储在移动终端的存储器中；同时设置各种特定使用条件下及其对应摄像头编号，也将该对应关系存储在移动终端的存储器中；当检测到用户的操作指令或其他应用启动摄像头时，先判断当前条件是否为特定使用条件，若为是则根据该特定使用条件下对应摄像头编号，对该摄像头编号对应的摄像头启动供电并打开摄像头；如果当前不是特定使用条件，则获取默认摄像头编号，对该摄像头编号对应的摄像头启动供电并打开摄像头。使通过一路供电控制来实现对双摄像头的供电，达到节省供电源的效果，从而节省硬件的相关器件、电路的成本。
基于上述方法实施例，本发明还提供了一种基于移动终端的双摄像头供电控制系统，如图4所示，所述系统包括：
