参见图1，图1是本申请实施例提供的摄像模组的结构图，如图1所示，摄像模组包括：
图像感应器11；
电能处理电路12；
图像处理电路13；
切换单元14，所述图像感应器11通过所述切换单元14与所述电能处理电路12和所述图像处理电路13中的一者导通；
在所述切换单元14导通所述图像感应器11和所述电能处理电路12的情况下，所述电能处理电路12用于对所述图像感应器11输出的信号进行电能搜集；
在所述切换单元14导通所述图像感应器11和所述图像处理电路13的情况下，所述图像处理电路13用于对所述图像感应器11输出的信号进行图像处理。
在该实施方式中，摄像模组可以包括图像感应器11，图像感应器11能够用于采集光信号，并将光信号转换为电信号。基于该电信号，在摄像模组处于不同的工作状态时，可以对获取的电信号进行不同的利用。
图像感应器11与切换单元14连接，切换单元14可以根据摄像模组的工作状态，与电能处理电路12或者图像处理电路13连接。
在切换单元14连接电能处理电路12的情况下，图像感应器11与电能处理电路12导通。图像感应器11采集光线，并将获取的光信号转换为电能，然后将转换的电能传送给电能处理电路12，电能处理电路12利用获取的电能进行充电。
在切换单元14连接图像处理电路13的情况下，图像感应器11与图像处理电路13导通。图像感应器11采集图像信息，并可以将采集的图像信息发给图像处理电路13，图像处理电路13可以根据获取的图像信息生成图像。
因此，切换单元14可以根据摄像模组的使用状态，对图像感应器11的连接进行控制。在摄像模组需要拍照时，切换单元14可以控制图像感应器11连接图像处理电路12，以保持正常的摄像工作；在摄像模组未拍照时，切 换单元14可以控制图像感应器11连接电能处理电路13，从而对电池充电，能够及时对电池电量进行补充，提高电池的续航能力。
在电子设备具备多个摄像头的情况下，可以利用多个摄像头的多个摄像模组对电池进行充电，能够提高充电效率。
这样，能够利用摄像头镜头的光线汇聚作用，并充分利用摄像头传感器自带的感光能力，采集环境光线并转换为电能，从而对电池进行充电，能够提高电子设备的续航能力。
可选的，如图2所示，所述切换单元14包括第一开关器件141和第二开关器件142；
所述第一开关器件141的第一端连接所述图像感应器11，所述第一开关器件141的第二端连接所述电能处理电路12；
所述第二开关器件142的第一端连接所述图像感应器11，所述第二开关器件142的第二端连接所述图像处理电路13。
其中，第一开关器件141可以是用于控制图像感应器11和电能处理电路12的连接和断开的器件，该器件具体可以是开关，还可以是金氧半场效晶体管(Metal-Oxide-Semiconductor Field-Effect Transistor,MOSFET)，等。
第二开关器件142可以是用于控制图像感应器11和图像处理电路13的连接和断开的器件，该器件具体也可以是开关，还可以是MOSFET等。
在摄像模组处于不同使用状态的情况下，可以分别控制第一开关器件141和第二开关器件142交替开启和关闭，从而满足摄像模组在不同使用状态下的不同使用需求。
可选的，如图2所示，所述切换单元14还包括控制器143，所述控制器143分别连接所述第一开关器件141的第三端和所述第二开关器件142的第三端；
所述控制器143用于控制所述第一开关器件141的第一端和第二端导通，或控制所述第二开关器件142的第一端和第二端导通。
在该实施方式中，在摄像模组未处于拍摄模式的情况下，可以控制摄像模组充电。具体地，控制器143可以控制第一开关器件141闭合，并控制第二开关器件142断开，使得图像感应器11和电能处理电路12连接，电能处 理电路12利用图像感应器11输出的电信号进行电能搜集，从而给电池充电。
而在摄像模组处于拍摄模式的情况下，可以控制摄像模组拍摄。具体地，控制器143可以控制第一开关器件141断开，控制第二开关器件142闭合，使得图像感应器11和图像处理电路13连接，图像处理电路13利用图像感应器11输出的电信号生成图像，从而进行拍摄。
以第一开关器件141和第二开关器件142均为MOSFET为例，控制器143与第一开关器件141和第二开关器件142的连接方式可以参见图2。对于第一开关器件141来说，控制器143可以与MOSFET的栅极连接，电能处理电路12可以与MOSFET的漏极连接，图像感应器11可以与MOSFET的元极连接。对于第二开关器件142来说，控制器143可以与MOSFET的栅极连接，图像感应器11可以与MOSFET的漏极连接，图像处理电路13可以与MOSFET的元极连接。
这样，控制器143能够根据摄像模组的使用状态，控制图像感应器与电能处理电路或与图像处理电路连接，摄像模组既能够进行拍摄还能够给电池充电，提高了操作灵活性以及节约成本。
可选的，所述控制器143用于接收控制信号，并在所述控制信号为第一控制信号时，控制所述第一开关器件141的第一端和第二端导通；在所述控制信号为第二控制信号时，控制所述第二开关器件142的第一端和第二端导通。
在该实施方式中，电子设备可以根据摄像模组的使用状态，向控制器143发出控制信号。控制器143接收控制信号后，可以根据控制信号的类型对不同的开关器件进行控制。
在需要给电池充电时，电子设备可以向控制器143发出第一控制信号。控制器143接收到第一控制信号后，控制第一开关器件141的第一端和第二端导通，也就是说，控制图像感应器11和电能处理电路12导通。此时，图像感应器11获取光信号并将光信号转换为电信号，电能处理电路12利用电信号进行充电。
在需要拍摄时，电子设备可以向控制器143发出第二控制信号。控制器143接收到第二控制信号后，可以控制第二开关器件142的第一端和第二端 导通，也就是说，控制图像感应器11和图像处理电路13导通。此时，图像感应器11获取光信号并将光信号转换为电信号，即，获取图像信息，图像处理电路13利用图像信息生成图像。
通过在摄像头传感器端增加电能处理电路，当电子设备进入拍照模式时，电能处理电路自动断开，不影响原有的拍照功能。当电子设备退出拍照模式时，自动切换到充电模式，此时电能处理电路开始电能搜集工作。这样，控制器143通过控制第一开关器件141和第二开关器件142的闭合和断开，从而控制摄像模组在不同的场景下进行充电或拍摄图像，能够灵活地控制摄像模组在不同场景实现不同的功能，能够减少成本。
