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.
• Maximum frame rate of sensor output
Sensor FR ＝ 1 / {H Period × (Height_s ＋ 36)}
• Maximum frame rate by interface
Interface FR ＝ 3000 × 1000000 / (Height×Width×Pack value)
• Maximum frame rate
FR_Cont ＝ Min （＜ SensorFR ＞ , ＜ InterfaceFR ＞）
• Exposure time possible within frames
MaxOverlapTime_TrOloff ＝ (1 / FR_Cont) － (1 / Sensor FR)
• Exposure time outside of frame interval
NonOverlapExposureTime_TrOloff ＝ ExposureTime － MaxOverlapTime_TrOloff
However, NonOverlapExposureTime_TrOloff calculation results that are 0 or below will be considered as 0.
For TriggerWidth, the trigger pulse is equivalent to ExposureTime.
• Maximum frame rate
FR_TrOloff ＝ 1 / { (1 / FR_Cont) ＋ NonOverlapExposureTime_TrOloff
}
• Maximum frame rate of sensor
Sensor FR ＝ 1 / {H Period × (Height_s ＋ 36)}
• Maximum frame rate by interface
Interface FR ＝ 3000 × 1000000 / (Height × Width × Pack value)
• Maximum frame rate
FR_TrOloff ＝ Min(Sensor FR, Interface FR)
• Exposure time possible within frames
MaxOverlapTime_TrOlrd ＝ (1 / FR_Cont) － (14 × H_Period)
• Exposure time outside of frame interval
NonOverlapExposureTime_TrOlrd ＝ ExposureTime － MaxOverlapTime_TrOlrd
However, NonOverlapExposureTime_TrOlrd calculation results that are 0 or below will be considered as 0.
For TriggerWidth, the trigger pulse is equivalent to ExposureTime.
• Maximum frame rate
FR_TrOlrd ＝ 1 / { (1 / FR_Cont) ＋ NonOverlapExposureTime_TrOlrd }
