Enable Trigger Cache Enable
If the camera receives the 1st trigger signal first, and the camera receives the 2nd trigger signal
during processing the 1st trigger signal.
Disable Trigger Cache Enable: the 2nd trigger signal will be filtered without processing.
Enable Trigger Cache Enable: the 2nd trigger signal will be saved.
If the 1st frame image’s exposure time of the 2nd trigger signal is not earlier than the camera’s last
frame creation time of the 1st trigger signal, and then the 2nd trigger signal’s 1st frame image is
created normally.
If the 1st frame image’s exposure time of the 2nd trigger signal is earlier than the camera’s last
frame creation time of the 1st trigger signal, and then the camera will delay this exposure time.
Thus making sure this exposure time is not earlier than the camera’s last frame creation time of
the 1st trigger signal.
