Acquisition Mode
Two camera acquisition modes are available: single frame acquisition mode and continuous acquisition
mode.
Single frame acquisition mode: In single frame acquisition mode, the camera will only acquire one
frame of image at a time.

When the trigger mode is set to On, the trigger type is arbitrary
After executing the AcquisitionStart command, the camera waits for a trigger signal, which may be a
software trigger or a hardware trigger of the camera. When the camera receives the trigger signal and
acquires an image, the camera will automatically stop image acquisition. If you want to acquire another
frame of image, you must execute the AcquisitionStart command again.
2)
When the trigger mode is set to Off
After executing the AcquisitionStart command, the camera acquires one frame of image and then
automatically stops image acquisition. If you want to acquire another frame of image, you must execute
the AcquisitionStart command again.
In single frame acquisition mode, you must execute the AcquisitionStop command to set the
functions that cannot be set in the acquisition status, such as ROI, packet size, etc.
Continuous acquisition mode: In continuous acquisition mode, the camera continuously acquires and
transmits images until the acquisition is stopped.
