Feature description 33
Both examples above above demonstrate if the trigger signal is before
exposure time, the camera will deliver a valid exposure OUT signal and
the image of the frame cycle where the trigger signal was put.
If the trigger arrives while exposure has already started the image of the
current frame cycle is dropped. The trigger signal will initiate delivery of
the following frame cycle’s image.
As it is not possible to determine in advance the time difference between
trigger impulse and start of the new image a timing jitter is the result.
Given that, maximum jitter is 1/fps.
Precise mode triggered
Precise mode triggering gives you exact knowledge about the start of
exposure. Precise mode trigger is requesting the camera to start with
exposure, frame cycle starts with trigger. As the sensor has to set up
before exposing, the first image cycle or frame is lost and the second
image will be delivered. With a static frame cycle, the exposure of the
second frame starts with a fixed delay of 1 frame.
Maximum imaging speed will be about half of fast mode triggered.
Benefit is the exact knowledge of exposure start time.
