Set Response Mode
Description
The camera supports two response modes, brief and verbose. In
verbose response mode the processed command response line
discussed in Section 5.2 is output. In brief response mode the
processed command response line is not echoed.

5.7.Non-Uniformity Corrections (NUCs) Commands
The factory operational configuration slots (OPRs) support two-point correction tables that can be used to
compensate for the dark signal and photoresponse non-uniformity of the FPA. The gain and offset
correction coefficients are unique for each operational setting. The correction table coefficients are
applied to create a corrected pixel value PIXCORR according to the following relation:
PIXCORR = ((PIXIN
−
CORROFF) × CORRGAIN/ 2048 ) + GLOBALCORROFF
where PIXIN is the raw pixel value, CORROFF is the offset correction value, CORRGAIN is the gain
correction value, and GLOBALCORROFF is the global corrected offset value. CORROFF and
CORRGAIN are unique for each FPA pixel and operational configuration slot. GLOBALCORROFF is
applied to every pixel of the frame. The correction commands allow the offset, gain, and pixel corrections
to be independently enabled or disabled. If offset correction is disabled, CORROFF and
GLOBALCORROFF are 0. If gain correction is disabled, CORRGAIN is 2048.
If either gain or offset correction is applied to the raw pixel data and a subsequent digital fixed gain of 1X
is used, some pixel values may not saturate at the full 12-bit resolution count value of 4,095. A fixed
digital gain greater than 1X can be applied to the corrected image data to guarantee that all pixels saturate
at the full scale value of 4,095 if needed or desirable.
5.7.1.
Set Gain Correction State
Description
Sets the state of the gain correction. Gain correction compensates
for pixel-to-pixel photoresponse non-uniformity. Otherwise known
as a white balance correction (multiplication).
