其中，所述通信接口模块25一般有两种：一种为USB端口，移动终端能通过USB端口获取电源；另一种通信接口模块25为采用无线通讯协议的端口，移动终端通过自身的电池获取电源。这里，无线通讯仅需要很小一部分电源来支持，而所述USB端口则不需要。
优选的，所述主机模块23，还配置为通过所述通信接口模块25在计算机上显示相机摄像头已可使用的界面，从而通知用户当前关机状态的移动终端的相机功能可用。也就是说，当移动终端与计算机连接后，计算机上会自动弹出一个界面，如“当前移动终端的相机功能可用”的界面。
本发明的实施例中，处于关机状态的移动终端可通过通信接口模块25以及连接线与计算机相连，供电模块20与通信接口模块25相连，在通信接口模块25与计算机通过连接线连接后，供电模块20通过通信接口模块25获取到计算机提供的电源。移动终端通过供电模块20的供电电路为判定模块22、相机设备21和主机模块23供电。
移动终端中的判定模块22对扫描码进行鉴别，确定当前移动终端处于关机状态时，所述判定模块22通知主机模块23打开移动终端的相机功能。所述相机功能主要是主机模块23通过通信接口模块25，如通过USB端口进行热插拔枚举，通过相机设备21的设备信息，将相机设备21枚举成USB设备，启动USB设备枚举，打开相机设备21中的通信模块和枚举模块，并通过USB传输控制协议或无线接口协议在通信接口模块25与计算机间进行数据传输，还通过此通信接口模块25控制设备枚举。
移动终端中的主机模块23通过相机设备端口模块24与相机设备21相连，并通过USB BULK协议控制相机设备21进行图像的采集，相机设备21最终将图像转换为图像信号后传输到主机模块23中，之后主机模块23将压缩处理后的数字图像信息通过通信接口模块25，如：USB端口传输到计算机，通过计算机的显示器显示图像，从而实现关机状态下移动终端相机的拍照、摄像功能。
图3为本发明一具体实施例所述移动终端内部部分结构示意图，如图3所示，在本发明的实施例中，所述主机模块23通过USB控制器芯片实现，所述通信接口模块25为USB端口，所述计算机为PC为例，具体的：
在关机模式下相机设备端口和主机PC模块相连，即：相机设备端口可与USB控制器芯片相连，将相机设备端口模块24中的相机数据接口DATA0-8、电源接口、时钟接口MCLK，VCLK等连接到USB控制器芯片，所述SCL，SDA为USB控制器芯片内部通讯接口，所述SCL为时钟线，所述SDA为数据、地址线，所述USB DM和USB DP对应USB控制器芯片的两跟数据命令线。USB控制器芯片连接USB端口，将D+、D-、电源和地等接口连到USB端口，USB端口连接到PC主机(图3中未显示)。PC主机为相机提供电源，实现USB设备的驱动。这里，所述USB设备即为相机设备。
其中，所述USB控制器芯片包括：镜像信号处理器，图片压缩处理器和USB控制器；镜像信号处理器以及图片压缩处理器将相机摄像头传来的数字图像信号进行压缩，并将压缩后的图像信号传输给USB控制器，USB控制器通过USB DP和USB DM数据线传给计算机。
在实际应用过程中，物体通过相机摄像头生成光学图像，并投射到图像传感器表面，然后转为电信号，经过模数转换(A/D)转换后变为数字图像信号，再传输到USB控制器芯片中进行处理，通过通信接口模块25，如：USB端口传输到计算机，如：传输到PC中处理，通过PC的显示器显示图像。
本发明实施例还提供了一种上述移动终端关机状态下实现相机功能的方法，如图4所示，包括如下流程：
步骤401：移动终端获取电源；
具体为：移动终端可通过通信接口模块25以及连接线与计算机相连，供电模块20与通信接口模块25相连，在通信接口模块25与计算机通过连接线连接后，供电模块20通过通信接口模块25获取到计算机提供的电源。移动终端通过供电模块20的供电电路为判定模块22、相机设备21和主机模块23供电。
其中，所述通信接口模块25一般有两种：一种为USB端口，移动终端能通过USB端口获取电源；另一种通信接口模块25为采用无线通讯协议的端口，移动终端通过自身的电池获取电源。这里，无线通讯仅需要很小一部分电源来支持，而所述USB端口则不需要。
步骤402：移动终端确定自身当前处于关机状态时，打开相机功能；
具体为：移动终端中的判定模块22对扫描码进行鉴别，所述扫描码就是管脚高低电平两种状态，为低电平时，则判定模块22确定移动终端处于关机状态。确定当前移动终端处于关机状态时，所述判定模块22通知主机 模块23打开移动终端的相机功能。所述相机功能主要是主机模块23通过通信接口模块25，如通过USB端口进行热插拔枚举，通过相机设备21的设备信息，将相机设备21枚举成USB设备，启动USB设备枚举，打开相机设备21中的通信模块和枚举模块，并通过USB传输控制协议或无线接口协议在通信接口模块25与计算机间进行数据传输，还通过此通信接口模块25控制设备枚举。
优选的，在移动终端打开相机功能后，本发明实施例方法还包括：移动终端在计算机上显示相机摄像头已可使用的界面，从而通知用户当前关机状态的移动终端的相机功能可用。也就是说，当移动终端与计算机连接后，计算机上会自动弹出一个界面，如“当前移动终端的相机功能可用”的界面。。
步骤403：移动终端将摄像头采集的数字图像传输到计算机，由计算机进行图像显示；
具体为：移动终端中的主机模块23通过相机设备端口模块24与相机设备21相连，并通过USB BULK协议控制相机设备21进行图像的采集，相机设备21最终将图像转换为图像信号后传输到主机模块23中，之后主机模块23将压缩处理后的数字图像信息通过通信接口模块25，如：USB端口传输到计算机，通过计算机的显示器显示图像，从而实现关机状态下移动终端相机的拍照、摄像功能。
