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.
7.5.4 Set Trigger Activation
The camera supports trigger acquisition in the rising edge, falling edge, level high, or level low of

Trigger Activation
Rising Edge
Rising Edge refers to the rising
edge of the trigger signal is
valid, that is camera exposure
and acquisition at the
beginning of the rising edge of
the trigger signal.
Falling edge
Acquisition Control >
Trigger Activation
Falling Edge
Falling Edge refers to the falling
edge of the trigger signal is
valid, that is camera exposure
and acquisition at the
beginning of the falling edge of
the trigger signal.
Level High
Acquisition Control >
Trigger Activation
Level High
Level High refers to the level
high of the trigger signal is
valid. As long as trigger signal is
in level high, the camera keeps
exposure and acquisition
status.
Level Low
Acquisition Control >
Trigger Activation
Level Low
Level Low refers to the level
low of the trigger signal is valid.
As long as trigger signal is in
level low, the camera keeps
exposure and acquisition
status.
