3.4.1.4. Timing Chart for END, CENTER and MANUAL Trigger Modes
The below chart shows the temporal relationship of timing signals in END trigger mode. Note the
exposure, and consequently recording, ends as soon as a trigger comes in.
Note: CENTER trigger mode ends recording after filling the latter half of the available memory.
MANUAL trigger mode records a preset number of frames after a trigger comes in.
Note: When shutter is used, the exposure period becomes shorter depending on the shutter speed.
See example in the timing chart in 3.4.1.3.
Note: The amount of delay between the incoming and internal triggers greatly depends on the type
of incoming triggers.
