Exposuremode - JAI GO-5100MP-USB User Manual

ExposureMode

The following exposure modes are available on the camera.
ExposureMode
Off
Timed
TriggerWidth
* The settings for exposure control and triggers are related to each other. Be sure to configure the
settings described in "Trigger Control".
Actual Exposure Times
The shortest exposure times that can be configured are as follows.
Exposure Mode
・The actual exposure time will consist of the image sensor's offset duration (13.7 μs) added
to the setting configured on the camera.
・When [ExposureMode] is set to [Timed] and the exposure time is set to 1 μs, the actual
exposure time will be as follows.
1 μs + 13.7 μs (offset duration of image sensor) = 14.7 μs
・When [ExposureMode] is set to [TriggerWidth], the exposure is slightly longer than the width
of the trigger signal. To achieve an exposure time of 14.7 µs and the exposure time offset
is 13.7 µs, use 14.7 µs - 13.7 µs = 1 µs as the high or low time for the trigger signal.
Exposure control is not performed (free-running operation).
Mode in which control is performed using exposure time. Acquire
images using an exposure time configured beforehand on an external
trigger.
Mode in which control of the exposure time is performed using the
pulse width of the trigger input signal. The exposure time will be the
same as the pulse width of the trigger input signal. This allows long
exposure.
