12.1.4 NUC
The NUC Non-Uniformity Correction) function performs an internal ca-
libration of the camera.
NUC can be performed in three different ways. With Internal NUC, the
image is calibrated against a shutter inside the camera. With External
NUC, either the lens cover or the scene is used as thermal reference.
An Internal NUC normally gives a good image quality.
NOTE: When the camera is started, a NUC is needed every 5 minutes. After about 30
minutes, a NUC is only needed when the quality of the image is degenerated.
