Calibrate Input LUT
Purpose: Calibrates the current input look-up table for correcting non-
linearity in the analog chain (CCD sense node and analog-to-
digital conversion).
Syntax:
cil
Syntax Elements:
Notes: This command calibrates all taps within the ROI for current
color (RBG does all).
To calibrate:
Place a white reference in front of the camera. This is similar to
a PRNU calibration.
Adjust the light level such that at maximum LUT line rate:
2K60 is equal to 10,501 Hz, and 4K60 is equal to 5,410 Hz.
Average output is less than 590 DN (12 bit) and at minimum
line rate average output is greater than 3,685 DN (12 bit)
In addition:
Use the wil command to write the LUT to non-volatile
memory.
Use the eil command to enable use of the LUT.
Use the scl command to select which colored taps to calibrate.
Use the roi command to limit the taps calibrated and to limit
which pixels are used for calibration. If a tap is not in the region
of interest, then it will not be calibrated.
Press spacebar to abort this command.
Rerun this command if the analog gain or operating temperature
changes.
Example:
Enable Input LUT
Purpose: Enables or disables the use of the input look-up tables for the
correction of the analog chain non-linearity.
Syntax:
eil flag
Syntax Elements:
0

Notes: Coefficients must be created first with the cil command.
Setting saved with the wfs and wus commands.
