Returning Camera Settings with Get Commands
You can also return ind ivid ual camera settings by inserting a ― get” in front of the command that you
want to query. If the command has a tap or pixel number parameter, you must also insert the tap number
or pixel number that you want to query. To view a help screen listing the following get commands, use
the command gh.
ASCII Commands: Reference
The follow ing table lists all of the camera’s available ASCII comm and s. Refer to Append ix A for d etailed
information on using these ASCII commands.

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 equ al to the
specified target value.
3 = This algorithm adjusts digital gain so that the
average p ixel 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
4055 DN (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
