 ### 具体实现
 * 相机功能接口实现在CameraService.ets，源码参考：[CameraService.ets](entry/src/main/ets/mode/CameraService.ets)
-    * 在CameraService的initCamera函数里完成一个相机生命周期初始化的过程，包括调用getCameraMananger获取CameraMananger，调用getSupportedCameras获取支持的camera设备，调用getSupportedOutputCapability获取支持的camera设备能力集，调用createPreviewOutput创建预览输出，调用createCameraInput创建相机输入，调用CameraInput的open打开相机输入，调用onCameraStatusChange创建CameraManager注册回调，最后调用sessionFlowFn创建并开启Session。

     * 其中sessionFlowFn是一个创建session并开启预览的动作，主要流程包括：调用createSession创建Session，调用beginConfig开始配置会话，调用addInput把CameraInput加入到会话，调用addPreviewOutput把previewOutput加入到会话，调用commitConfig提交配置信息，调用start开始会话工作。
     * 在CameraService的releaseCamera函数里完成对相机生命周期释放的过程，调用output的release方法释放流，调用CameraInput的close方法关闭相机，再调用session的release释放当前会话。

 * 相机预览、拍照，录像功能实现调用侧位于Index.ets，ModeComponent.ets中，源码参考：[Index.ets](entry/src/main/ets/pages/Index.ets)，[ModeComponent.ets](entry/src/main/ets/views/ModeComponent.ets)
