若用户在应用中的操作是启用动感音乐模式，则获取音乐的频率；
根据所述音乐的频率，确定所述闪光灯的点亮频率。
基于上述硬件结构，提出本发明闪光灯的控制方法各个实施例。
参照图2，本发明闪光灯的控制方法第一实施例提供一种闪光灯的控制方法，所述方法包括：
步骤S10，根据用户在应用中的操作识别闪光灯的工作场景；
步骤S20，根据所述工作场景确定所述闪光灯的工作模式；
步骤S30，根据所述闪光灯的工作模式确定向闪光灯输入的电流值，并根据所述电流值控制相应的闪光灯。
在本实施例中，移动终端可以是智能手机、平板电脑或掌上电脑等可移动式终端设备。以智能手机为例进行说明，目前市面上大多数智能手机采用后置单闪光灯的设计，那么在拍照使用时，照亮的范围不够广阔，对于全景拍照等拍照模式来说，整体画面的光线可能就存在光线不够均匀的情况。另外，闪光灯一般在拍照或当作手电筒时使用，使用场景较为单一。为此，本实施例提供一种闪光灯的控制方法。
本实施例中，移动终端上至少布置有两个闪光灯。本实施例以布置两个闪光灯为例，两个闪光灯对称置于后置摄像头的两边，与后置摄像头位于同一直线上（与后置摄像头形成180°夹角），示意图参照图6。通过这种双闪光灯的设计，如果两个闪光灯同时开启，闪光灯的出射角范围更大，可参照图7，那么可照亮的范围更为广阔，且闪光灯开启时照不到的死角的范围也会减小。
本实施例中，首先根据用户在应用中的操作识别闪光灯的工作场景。
具体地，所述应用可以是移动终端中的相机APP，视频拍摄APP，或者其他可调用移动终端摄像头的应用软件，还可以是音乐播放软件。在识别闪光灯的工作场景之前，需确定调用闪光灯的应用。然后根据用户在应用中的操作识别出闪光灯的工作场景。比如，检测到调用闪光灯的应用是可调用移动终端摄像头的应用软件，此时，基于用户开启摄像头的操作，判断出闪光灯是用户拍照时使用。
在确定闪光灯的工作场景后，根据闪光灯的工作场景确定闪光灯的工作模式。以用户在拍照时使用闪光灯为例进行说明。若闪光灯的工作场景是，用户在可调用摄像头的应用软件中启用摄像头进行拍照，则通过开启的摄像头获取当前环境的光线强度，即利用移动终端的摄像头检测当前环境的光线强度，具体地，移动终端的摄像头摄取当前环境图像，然后对当前环境图像进行分析，得到当前环境光线的分析结果。若分析结果为，当前是黑暗环境，那么就确定闪光灯的工作模式为两个闪光灯同时点亮。
本实施例中移动终端的闪光灯都是电子闪光灯，发光原理为对输入电流进行振荡升压，获得大于300V的交变电压，经二极管半波整流后变成直流电压，对电容进行充电储能，触发时电容产生脉冲电压，通过氙气闪光灯管的触发电级使其中的氙气电离并导通，电容上的电能瞬间被氙气瞬间转化为光能，完成一次闪光。闪光灯的速度很快，一般单次触发点亮的时间最长不超过1/200秒。故闪光灯在拍照时使用的话，闪光灯所发出的光皆为"短暂光"，而非"持续光"。
因此，本实施例中，可通过控制输入闪光灯的电流值控制闪光灯是否触发点亮。如上所述，在识别出用户是在拍照时使用闪光灯，且通过摄像头检测出当前是黑暗环境时，确定两个闪光灯需同时点亮后，进一步确定向两个闪光灯输入的电流值，根据该电流值向两个闪光灯输入对应的电流，使两个闪光灯同时点亮，达到同时进行闪光的效果。
作为一种实施方式，本实施例中对于摄像头检测出当前环境的光线有弱有强（明暗环境）的情况，可预先设置摄像头算法，摄像头算法是指摄像头可根据检测到的当前环境的光线强度，以较强光线为基准，计算较弱光线达到较强光线所需补充的光线强度。当移动终端的摄像头摄取当前环境图像，然后对当前环境图像进行分析，得到的分析结果为当前环境的光线有弱有强时，为使拍摄画面光线均匀，则结合预设摄像头算法，确定较弱光线所需补充的光线强度。进一步地，根据该较弱光线所需补充的光线强度，确定较弱光线的位置所对应的闪光灯需输入的电流值，并根据该电流值向较弱光线的位置所对应的闪光灯输入对应的电流，以使该对应的闪光灯触发点亮以进行补光。
在更多的实施中，若检测到调用闪光灯的应用是音乐播放软件，基于用户打开动感音乐模式的操作，可判断出闪光灯的工作场景是，需闪光灯随音乐节奏进行闪光以渲染气氛，此时，获取播放的音乐的频率，并根据音乐的频率确定闪光灯的闪光频率。具体地，获取音乐的音频流信息，以使闪光灯的控制电路对该音频流信息进行解析，得到解析结果，并根据该解析结果确定向两个闪光灯输入的电流值。比如，若将两个闪光灯作为一个整体，那么，高音频时两个闪光灯对应一个电流值，即高音频时同时向两个闪光灯输入该电流值对应的电流，触发两个闪光灯同时点亮，低音频时两个闪光灯对应的电流值为零，即低音频时两个闪光灯同时熄灭；另外，可将两个闪光灯分为两路，并预设一个音频阈值区分音频的高低，一路为其中一个闪光灯对应高音频，一路为另一个闪光灯对应低音频，即当音频达到阈值时，向高音频对应的闪光灯输入电流触发点亮，当音频低于阈值时，向低音频对应的闪光灯输入电流触发点亮，实现两个闪光灯随音乐频率进行闪烁。其中，为区分音频的高低而预设的音频阈值可根据实际进行设置，此处不做限定。
本实施例在移动终端上至少布置两个闪光灯，首先根据用户在调用闪光灯的应用中的操作，识别闪光灯的工作场景，并根据工作场景确定闪光灯的工作模式，即确定闪光灯是同时点亮还是其中一个点亮等，进一步地，根据闪光灯的工作模式确定向闪光灯输入的电流值，通过该电流值确定向闪光灯输入的电流，以控制闪光灯的明灭，通过这种方式，本实施例中的闪光灯若在拍照时使用，可通过控制闪光灯使拍摄时的整体画面光线更加均匀，本实施例中的闪光灯也可在播放音乐时使用，通过控制闪光灯使得闪光灯随着音乐频率闪动，从而渲染气氛，增加趣味性。
进一步的，参照图3，本发明闪光灯的控制方法第二实施例提供一种闪光灯的控制方法，基于上述图2所示的实施例，步骤S20包括：
步骤S21，若用户在应用中的操作是启用摄像头进行拍照，则通过摄像头获取当前环境的光线强度；
步骤S22，根据所述当前环境的光线强度，确定所述闪光灯的工作模式。
本实施例中，在识别出闪光灯的工作场景是在可调用摄像头的应用软件中启用摄像头进行拍照时，则通过开启的摄像头获取当前环境的光线强度，即利用移动终端的摄像头检测当前环境的光线强度。然后，根据当前环境的光线强度确定闪光灯的工作模式，具体地，参照图4，步骤S22包括：
步骤S220，若当前是黑暗环境，则确定所述闪光灯的工作模式为闪光灯同时点亮；
步骤S221，若当前环境的光线有弱有强，则结合预设摄像头算法，确定所述闪光灯的工作模式为对应的闪光灯点亮以进行补光。
移动终端的摄像头获取当前环境的光线强度，即移动终端的摄像头摄取当前环境图像，然后对当前环境图像进行分析，得到当前环境光线的分析结果。若分析结果为，当前是黑暗环境，那么就确定闪光灯的工作模式为两个闪光灯同时点亮。若分析结果为，当前环境的光线有弱有强（明暗环境），可预先设置摄像头算法，即摄像头可根据检测到的当前环境的光线强度，以较强光线为基准，计算较弱光线达到较强光线所需补充的光线强度，从而使较弱光线的位置所对应的闪光灯点亮进行补光。
本实施例中，步骤S20还包括：
步骤S23，若用户在应用中的操作是启用动感音乐模式，则获取音乐的频率；
步骤S24，根据所述音乐的频率，确定所述闪光灯的点亮频率。
在识别出闪光灯的工作场景是在音乐播放软件中随音乐节奏进行闪光时，则获取音乐播放软件播放的音乐的频率，并根据音乐的频率确定闪光灯的点亮频率。比如，若将两个闪光灯作为一个整体，那么，高音频时，两个闪光灯同时点亮，低音频时两个闪光灯同时熄灭；另外，可将两个闪光灯分为两路，并预设一个音频阈值区分音频的高低，一路为其中一个闪光灯对应高音频，一路为另一个闪光灯对应低音频，当音频达到阈值时，高音频对应的闪光灯点亮，当音频低于阈值时，低音频对应的闪光灯点亮，实现两个闪光灯随音乐频率进行闪烁的效果。
本实施例根据闪光灯的工作场景确定闪光灯的工作模式，也就是说，本实施例中的闪光灯有多种使用场景，不同的使用场景对应不同的工作模式，若在拍照时使用，可使拍摄时的整体画面光线更加均匀，若在播放音乐时使用，可使闪光灯随着音乐频率闪动，从而增加趣味性。
此外，本发明实施例还提出一种移动终端。
