Description
Sets the mode for the Auto-Brightness function.
Off Disable the auto-brightness mode.
Active Activates the auto-brightness mode when the
AcquisitionStart or AcquisitionArm command is
received.
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.
< DFNC Expert >
Adjust Exposure, Gain, in that order to achieve
the auto-brightness target value.
Adjust Gain, Exposure, in that order, to achieve
the auto-brightness target value.
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.
Luminance The luminance or Y component of the image is
used as the auto-brightness target source.
The Raw Bayer Pattern of the image is used as
the auto-brightness target source.
Sets the target image grayscale value, in DN, for
the auto-brightness algorithm. Features that use
auto-brightness include ExposureAuto, and
GainAuto.
Sets the auto-brightness target Range Variation in
(DN). An autoBrightnessTarget value within this
range is considered valid and will not be
compensated.
Specifies the auto-brightness algorithm used to
calculate the brightness in the target image
source plane(s).
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.
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.
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.
Sets the automatic exposure mode when the
ExposureMode feature is set to Timed.
Off Exposure duration is manually controlled using
the ExposureTime feature.
Continuous Exposure duration is constantly adapted by the
camera to meet the auto-brightness target pixel
value.
