InitializeCamera
Initialize the camera to the intended state (includes sending the 'InitCameraCommands' defined in the GevImageAcquisition TcCOM module to the camera).
Syntax
Definition:
METHOD InitializeCamera : HRESULT
Return valueFurther information
The method InitializeCamera initializes a connected GigE Vision camera just as the parameters in the stored initialization commands have been configured. This method should be used to explicitly control when the camera is initialized. To do this, the InitializationAutoMode in the TcCOM parameters of the Image Acquisition object must be set to NO_AUTOINIT. As a result of this, no automatic camera initialization is performed; instead, it must be done manually by means of InitializeCamera.
If a different selection was made with InitializationAutoMode, an automatic initialization takes place and the InitializeCamera method is not required
The initialization of a GigE Vision camera consists of the following steps:
- Opening the Control Channel to the camera
- Executing the Force-IP commands (optional)
- Setting a UserSet or writing Initialization Commands.
The function block assumes the INITIALIZING state during initialization. The function block enters the INITIALIZED state once the initialization is complete. It also assumes this state if the camera connection in the OPENED state is closed by calling the method CloseCamera.
State transitions
With InitializeCamera, the camera is to be brought from the INITIAL state to the INITIALIZED state. As a rule, this transition takes place via the intermediate state INITIALIZING.
