AgcMaxLimitReached:
Returns
a value ‘1’ if the
maximum digital gain limit was reached
while in AGC mode. Otherwise, the value is zero.
AecExposureCurrentValue:
Displays exposure value in microseconds, calculated by the
camera in AEC mode.
AecMinLimitReached:
Returns
a value of ‘1’ if
the minimum exposure limit was reached
during AEC mode. Otherwise, the value is zero.
AecMaxLimitReached:
Returns a value of ‘1’ if
the maximum exposure limit was reached
during AEC mode. Othersie, the value is zero.
CurrentAvgOrPeakLuminance:
Returns the current average or peak luminance.
AgcAecStatus:
Internal use only.
4.7.7 Data Correction Controls
These parameters enable data correction and image improvements with Look-up tables
and file corrections.
Figure 23: Data correction parameters.
LUTSelector
: Selects the lookup table, either LUT1 or LUT2, to use.
LUTEnable
: Enables the selected LUT.
FFCSelector
: Select either Flat Field Correction, either FFC1 or FFC2.
FFCEnable
: Enables Flat Field Correction. Normally, FFC1 should be enabled to minimize
Fixed Pattern Noise.
FixedPatternNoiseCorrection
: Determines Fixed Pattern Noise Correction allowing you to
implement a custom Fixed Pattern Noise (FPN) solution, if desired. Normally, you should
enable FPN.
DefectPixelCorrection
: Provides the following three modes of correction (5.14 Defective
Pixel Correction):
•
Static
: corrects defective pixels using a factory or user-supplied table of
defective pixel locations.
•
Dynamic
: corrects defective pixels on the fly (dynamically) based on a user-
defined threshold.
•
Both
: applies both Static and Dynamic defective pixel correction (DPC).
