The process is as follows: Call **OH_Camera_GetCameraMananger** to obtain CameraMananger, call **OH_CameraManager_CreateCaptureSession** to create CaptureSession, call **CaptureSessionRegisterCallback** to register a callback for CaptureSession, call **GetSupportedCameras** to obtain supported cameras, call **GetSupportedOutputCapability** to obtain supported camera capabilities, call **CreatePreviewOutput** to create a preview output, call **CreateCameraInput** to create a camera input, call **CameraInputOpen** to open the camera input, call **CameraManagerRegisterCallback** to register a callback for CameraManager, and call **SessionFlowFn** to enable the session. + * Camera initialization is implemented in the **NDKCamera** constructor.

The process is as follows: Call **OH_CameraManager_DeleteSupportedCameras** to delete supported cameras, call **OH_CameraManager_DeleteSupportedCameraOutputCapability** to delete supported camera capabilities, and call **OH_Camera_DeleteCameraManager** to delete CameraManager. * Photographing interfaces are encapsulated in the **StartPhoto** interface. The process is as follows: Call **SessionStop** to close the session, call **SessionBegin** to perform a preset action for the session, call **CreatePhotoOutput** to create a camera output, call **OH_CaptureSession_AddPhotoOutput** to add a photo output to the session, call **SessionCommitConfig** to commit the session configuration, call **SessionStart** to start the session, and then call **TakePicture** to take a photo. -- Gitee
