ExposureMode
The following exposure modes are available on the camera.
* The
settings for exposure control and triggers are related to each other. Be sure to configure the
settings described in “Trigger Control”.
ExposureMode
Description
Off
Exposure control is not performed (free-running operation).
Timed
Mode in which control is performed using exposure time. Acquire
images using an exposure time configured beforehand on an external
trigger.
TriggerWidth
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.

Actual Exposure Times
The shortest exposure times that can be configured are as follows.
・
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.
