Figure 4.6: Triggered Image Acquisition of single Frames
by the acquisition frame rate value and the acquisition frame rate enable configuration
(see Section 4.2.2 for more information)
Frame Burst Start Trigger Mode = off The frame burst start triggers are ignored. No capturing
of burst of frames is started.
It is possible to set both, the mode of frame start trigger and frame burst start
trigger, to on. In this case, the camera starts a single frame or a burst of frame
capture, depending which trigger arrives first.
Fig. 4.7 shows the procedure of a burst of frames and a single frame capture. The Acquisition
start and end trigger mode is on. So the camera waits for an acquisition trigger once the
acquisition command has been executed. During this period any frame burst start or frame
start triggers are ignored. As soon as an acquisition start trigger has been received, the camera
waits for frame triggers. It can be a frame start trigger or a frame burst start trigger.
Depending which trigger - frame start or frame burst start - arrives first, the camera starts a
single frame or burst of frame acquisition.
4.3.3 Frame Burst End Trigger
The frame burst end trigger can be used to abort a current running burst capturing cycle. The
main property of this trigger is the trigger mode. It can be set to on or off:
Frame Burst End Trigger Mode = on The frame burst end trigger is processed only, when burst
acquisition cycle is active. Once this trigger has been received, it waits, until the current
frame has been processed and then aborts the burst cycle. The camera status goes to
"Frame Trigger Wait" again.
Frame Burst End Trigger Mode = off The frame burst end triggers are ignored.
The value "Acquisition Burst Frame Count" is ignored when the mode of the
frame burst end trigger is set to on. It means, when a burst capture has been
started, the camera captures frames until a frame burst end trigger arrives.
