ExposureMode
values:
•

– Disables the Exposure and let the shutter open.
•
TriggerWidth
– Uses the width of the current Frame or Line trigger signal(s)
pulse to control the exposure duration. Note that if the Frame or Line
TriggerActivation is RisingEdge or LevelHigh, the exposure duration will be the
time the trigger stays High. If TriggerActivation is FallingEdge or LevelLow, the
exposure time will last as long as the trigger stays Low.
•
Timed
– Timed exposure. The exposure duration time is set using the
ExposureTime or ExposureAuto features and the exposure starts with the
FrameStart or LineStart.
2
ExposureTime
- The maximum exposure time is equal to the frame period. For longer
exposure times, increase the frame period using the Acquisition Frame Time
feature or the Acquisition Frame Rate feature.
