Setting parameters:GainSelector = DigitalGreenAll

Notes

• When using pixel gain, the output level interval may

not be continuous. This phenomenon occurs when

there is not video output signal that corresponds to the

output step. This is not a malfunction.

• If pixel gain is set to high, noise may be apparent. This

is not a malfunction.

• When specifying the upper or lower limit of the

exposure time, be sure to observe the following

requirements.

Exposure Time

The camera provides both manual and automatic

exposure control capabilities.

Manual exposure control

Exposure for the specified time is achieved by internal

continuous driving or Trigger Edge operation.

Setting parameter: ExposureTime = 10 to 2,000,000 (us)

Auto exposure control

The camera provides the auto exposure control function

to automatically control exposure time according to a

common user-specified detection frame and image

average level sharing with auto gain control function.

The upper and lower limits of the variable range are

adjustable.

If the auto exposure control is set to "Once," it

automatically changes to "Off" when the exposure time

reaches the image average level or the upper or lower

limit of the variable range. With the "Continuous"

setting, auto exposure control constantly operates.

When both auto exposure control and auto gain control

are activated, gain is lowered and exposure time is

extended within the variable range.

Setting parameters:ExposureAuto = Off/Once/

Continuous

ExposureAutoSpeed = 1 to 256

ExposureAutoLowerLimit = 10 to

2,000,000 (us)

ExposureAutoUpperLimit = 10 to

2,000,000 (us)

Note

Neither the upper nor lower limits of the exposure time

variable range affect the configurable range of exposure

time setting by manual exposure control.

When specifying the upper or lower limit of the

exposure time, be sure to observe the following

requirements.

ExposureAutoLowerLimit < ExposureAutoUpperLimit
