Mnemonic Syntax Parameters
Description
correction calibrate fpn
ccf
Performs FPN calibration and
eliminates FPN noise by subtracting
away individual pixel dark current.
calculate camera gain
ccg
i t i
Calculates the camera gain according to
the selected algorithm.
i = Calibration algorithm to use.
1 = This algorithm adjusts analog
gain so that 8% to 13% of tap ROI
pixels are above the specified target
value.
2 = This algorithm adjusts analog
gain so that the average pixel value
in tap’s ROI is equal to the
specified target value.
3 = This algorithm adjusts digital
gain so that the average pixel value
in tap’s ROI is equal to the
specified target.
4= This algorithm adjusts the
analog gain so that the peak tap
ROI pixels are adjusted to the
specified target.
t = Tap value. Use 0 for all taps or 1
or
2 for individual tap selection
depending on camera model.
i = Calibration target value in a range
from
1024 to 4055DN (12 bit LSB).
correction calibrate prnu
ccp
Performs PRNU calibration and
eliminates the difference in responsivity
between the most and least sensitive
pixel creating a uniform response to
light.
calibrate input LUT
cil
Calibrates the input lookup table (LUT).
The LUTs are used to remove
nonlinearity from the analog chain.
Parameters:
t = tap id
i = integer value
f = float
m = member of a set
s = string
x
= pixel column number
y
= pixel row number
