Syntax
Definition:
METHOD StartAcquisition : HRESULT
Return valueFurther information
The method StartAcquisition starts the image acquisition by a camera. What this means in the individual case depends on the parameterization of the camera. Further information about this can be found in the sample Image acquisition and trigger. The image acquisition can be started from the INITIAL, INITIALIZED and OPENED states.
If the camera is still in INITIAL or INITIALIZED, the method StartAcquisition also performs the tasks of the method OpenCamera. Usually, the OPENED state is not assumed.
State transitions
With StartAcquisition the camera is to be placed in the ACQUIRING state. This can take place from the INITIAL, INITIALIZED and OPENED states. If the camera is in INITIAL or INITIALIZED, the state transition to OPENED is performed first. As a rule, this takes place via the intermediate state OPENING. The transition from OPENED to ACQUIRING usually takes place via the intermediate state STARTACQUISITION.
