DFNC
Off Off Disable the auto-brightness mode.
Active Active Activates the auto-brightness mode when the
AcquisitionStart or AcquisitionArm command is
received.
Auto-Brightness
Sequence
autoBrightnessSequence Specifies the processing order for the auto-
brightness algorithm. Gain and Exposure are
adjusted sequentially, in the selected order, to
achieve the auto-brightness target value. If the
Gain or Exposure features are not available or
disabled, that feature is ignored in the processing
sequence.

Exposure \ Gain Exposure_Gain_Iris Adjust Exposure, Gain, in that order to achieve
the auto-brightness target value.
Gain \ Exposure Gain_Exposure_Iris Adjust Gain, Exposure, in that order, to achieve
the auto-brightness target value.
Auto-Brightness Target
Source
autoBrightnessTargetSource Specifies the source image color plane(s) used by
the Auto-Brightness algorithm to determine the
brightness adjustment required to obtain the
auto-brightness target value.

DFNC
Luminance Luminance The luminance or Y component of the image is
used as the auto-brightness target source.
Raw Bayer Pattern RawBayerPattern The Raw Bayer Pattern of the image is used as
the auto-brightness target source.
Auto-Brightness Target autoBrightnessTarget Sets the target image grayscale value, in DN, for
the auto-brightness algorithm. Features that use
auto-brightness include ExposureAuto, and
GainAuto.

Auto-Brightness Target
Variation
autoBrightnessTargetRangeVariation Sets the auto-brightness target Range Variation in
(DN). An autoBrightnessTarget value within this
range is considered valid and will not be
compensated.

Auto-Brightness
Algorithm
autoBrightnessAlgorithm Specifies the auto-brightness algorithm used to
calculate the brightness in the target image
source plane(s).
1.04
Expert
DFNC
Average Average The auto-brightness algorithm calculates the
average luminance from the camera image and
determines if the brightness should increase or
decrease based on the requested target
brightness.
Auto-Brightness
Minimum Time
Activation
autoBrightnessAlgoMinTimeActivation Specifies the time delay between an image
brightness change from the autoBrightnessTarget
and when compensation of Gain/Exposure starts.
This eliminates repetitive adjustments of short
term brightness variations.

DFNC
Auto-Brightness
Convergence Time
autoBrightnessAlgoConvergenceTime Specifies the maximum time the
autoBrightnessAlgorithm should take to
compensate the image brightness as defined by
the autoBrightnessTarget. Actual times typically
are less but may on occasion be more.
1.04
Expert
DFNC
Auto-Exposure ExposureAuto Sets the automatic exposure mode when the
ExposureMode feature is set to Timed.
1.04
Expert
Off Off Exposure duration is manually controlled using
the ExposureTime feature.
Continuous Continuous Exposure duration is constantly adapted by the
camera to meet the auto-brightness target pixel
value.
