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
the trigger input signal. The exposure time will be the same as the pulse width of
the trigger input signal.
Exposure control is not performed (free-running operation).
The exposure time is the longest possible time within the operating conditions such
as the frame rate.

Trigger
* The settings for exposure control and triggers are related to each other. Be sure to
configure the settings described in “Trigger Control”.
* When [ExposureTimeMode] is set to [Individual], you can set the exposure times for
Red, Green, and Blue individually. To set the exposure time individually for Red, set
[ExposureTimeSelector] to [Red], and configure the exposure time for Red in
[ExposureTime]. Similarly, configure the exposure times individually for Green and Blue.
Actual Exposure Times
Acquisition
Control
This camera has three Exposure modes (Off, Timed, TriggerWidth).
Use [AcquisitionControl] settings to perform operations and settings for exposure.
The minimum exposure time that can be configured are as follows.
The actual exposure time will consist of the image sensor’s offset duration (13.73 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
+ 13.73
μs
(offset duration of image sensor) = 14.73
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 14.73
μs
and the
exposure time offset is 13.73
μs
, use 14.73
μs
- 13.73
μs
= 1
μs
as the high or low
time for the trigger signal.
