Returns the value at specified LUT index entry of the
LUT selected by the LUT Selector feature.
Sets the mode for the Flat Field correction.
Off Flat Field Correction is disabled.
Flat Field Correction is enabled.
When selected, the camera is configured for flat field
correction calibration. The device may automatically
adjust some of its features when calibrate mode is
enabled. The features that are automatically adjusted
are device specific. The device will not restore these
features when the Flat Field Correction Mode feature is
changed from Calibrate mode to another mode.
Specifies the current set of Flat Field coefficients to use.
User data is uploaded via the file access feature.
Feature used when flatfieldCorrectionMode is Active. In
Calibration, changing this feature has no effect unless
you save the FFC, where this feature defines where to
save the values. This feature also can be used to copy
FFC sets.
Sets the factory Flat Field coefficient table as the current
Flat Field.
Sets User Flat Field 1 coefficient table as the current Flat
Field.
Sets User Flat Field 2 coefficient table as the current Flat
Field.
Sets User Flat Field 3 coefficient table as the current Flat
Field.
Sets User Flat Field 4 coefficient table as the current Flat
Field.
Specifies the Flat Field correction type.
Flat field correction is based on an individual line
(FlatLine).
Specifies the Flat Field correction algorithm to use.
The following formula is used to calculate the flat field
corrected pixel: newPixelValue[x] =
(sensorPixelValue[x] - FFCOffset[x]) * FFCGain[x]
Specifies the flatfield calibration algorithm to use.
Peak Each pixel is gained up to the brightest.
Each pixel is gained up to the value specified in the
flatfieldCalibrationTarget feature.
Sets the target pixel value for the gain (PRNU)
calibration.
Set flat field calibration sample size (number of lines to
sum).
2048
4096
Performs Fixed Pattern Noise (FPN) calibration by
reducing to zero dark pixel current using a pixel offset.
Performs Photo Response Non-Uniformity (PRNU)
calibration to a targeted, user-defined value. PRNU
calibration eliminates the difference in responsivity
between the most and least sensistive pixel, creating a
uniform response to light.
Sets the ROI Width.
Performs Fixed Pattern Noise (FPN) calibration by
reducing to zero dark pixel current using a pixel offset.
