3.2 FIELD CALIBRATION COMMANDS
Field calibrations may be performed at any time during camera operations to improve image
quality. The most common is the 1-point calibration, wherein the shutter is closed, raw pixel
samples are collected and averaged for some number of frames (default is 4), new NUC offsets are
computed from the averaged samples, and the shutter is opened to resume operations.
The 1-point no shutter field calibration allows the camera to compute NUC offsets that compensate
for lens non-uniformities. When this operation is performed, the camera should be pointed at a
black body or suitable substitute that is at uniform temperature. The shutter is not operated during
this operation and should be open prior to initiation.
3.2.1 Field Calibrate – 0x27
Description: Perform a calibration operation. The TIM supports several types of
calibrations. Use this command to service pending calibrations, including range change, if
Automatic Calibration Activity has been disabled.
