Appendix A: ASCII Command Reference
ASCII Commands: Reference
The following table lists and describes all of the camera’s available ASCII commands.
Table 9: Command Quick Reference
Mnemonic Syntax Parameters Description
correction calibrate fpn ccf Performs FPN calibration and
eliminates FPN noise by subtracting
away individual pixel dark current.
Measures FPN (dark current). Use the
epc command to enable subtracting
these values from the video. Use wfc
to write these values to non-volatile
memory.
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
(system) 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 4 for individual tap selection
depending on the color selected using
the scl command.
i = Calibration target value in a range
from 1024 to 4055DN (12 bit LSB).
correction calibrate prnu ccp Performs PRNU calibration in order to
eliminate the difference in responsivity
between the pixels to create 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.
camera link mode clm Selects the CameraLink mode.
calculate PRNU
algorithm
cpa i1 i2 Performs PRNU calibration according
