Description
tap's analog gain so that 8-13% of
pixels within a tap are above the value
specified in the target value parameter.
PRNU calibration then occurs using
the peak pixel in the region of interest.
(Identical to ccp)
2 = Calculates the PRNU coefficients
using the entered target value as shown
below:
Target
PRNU Coefficient =
(AVG Pixel Value) - (FPN+
The calculation is performed for all
sensor pixels but warnings only apply
to pixels in the region of interest. This
algorithm is useful for achieving
uniform output across multiple
cameras.
3 = This algorithm includes an analog
gain adjustment prior to PRNU
calibration. Analog gain is first adjusted
so that the peak pixel value in tap's
ROI is within 97 to 99% of the
specified target value. It then calculates
the PRNU coefficients using the target
value as shown below:
Target
PRNU Coefficient =
i
(AVG Pixel Value ) ‐ (FPN +
i
The calculation is performed for all
sensor pixels but warnings only apply
to pixels in the region of interest. This
algorithm is useful for achieving
uniform output across multiple
cameras.
4 = This algorithm is the same as 2
with the exception that it only
calculates PRNU for the pixels within
the current Region of Interest (ROI).
The second parameter is the target
value to use in a range from 1024 to
4055 DN.
i2 = Output target.
Sets the number of lines to sample
when using the gla command or
when performing FPN and PRNU
calibration where m is 1024, 2048,
or 4096.
Displays the range of input LUT
values, where:
t = Tap number: 0 for all. The range
is modified by the color selected.
a1 = Range start address: 0 to 1023.
a2 = Range stop address: 0 to 1023.
a1 ≤ a2
