Exposure Mode
ExposureMode = Off
ExposureMode = Timed
ExposureMode = TriggerWidth
Mode in which control is performed using exposure time. Acquire images using an
exposure time configured beforehand on an external trigger.
In this mode, the exposure time can be adjusted automatically by setting
[ExposureAuto]. For details, refer to “ALC (Automatic Brightness Control) Function”.
Mode in which control of the exposure time is performed using the pulse width of
