Mode
defectivePixelReplacementMode
Enable or disable pixel replacement.
If Active: If FPNx,y >
defectivePixelReplacementOffsetThreshold OR
PRNUx,y >
defectivePixelReplacementGainThreshold, then
Pixelx,y is replaced using the algorithm below.

Pixel Replacement
Offset Threshold
defectivePixelReplacementOffsetThreshold
The FFC base offset value(FPN) above which the
pixel are deemed hot pixels and replaced. This
value can be adjusted to replace more or fewer
pixels.
Possible values are:1 to 4096, as float

Pixel Replacement
Gain Threshold
defectivePixelReplacementGainThreshold
The FFC gain value (PRNU) above which the
pixel are deemed dead pixels and replaced. This
value can be adjusted to replace more or fewer
pixels.
Possible values are:1 to 4, as float

Average/Copy
Adjacent
Method1 The algorithm consists of averaging the
adjacent pixels when replacing a single defect
and copying the nearest pixel when replacing
two consecutive defects or a defect at the
beginning or end of a line, i.e.
A= pixel A
B= pixel B
X= defect
AXB is corrected to ACB where:
C= (A+B)/2
AXXB is corrected to AABB
XA is corrected to AA
BX is corrected to BB
Average/Weighted
Average
Method4 Algorithm consists of averaging the adjacent
pixels when replacing a single defect and
performing a weighted average when replacing
two consecutive defects. A defect at the
beginning or end of a line is not corrected, i.e.
A= pixel A
B= pixel B
X= defect
AXB is corrected to ACB where:
C= (A+B)/2
AXXB is corrected to ACDB where
C = (11 *A + 5*B)/16
D = (5*A + 11*B)/16
XA is not corrected
BX is not corrected
FPN Base Defect
Count
flatfieldCalibrationFPNBaseDefectCount
Reports the number of defect pixels detected in
FPN base calibration.
