12.2.4 NUC
The NUC Non-Uniformity Correction) function performs an internal cali-
bration of the camera.
NUC can be performed in three different ways. With Internal NUC, the
image is calibrated against a shutter inside the camera (Internal shutter).
With External NUC, either the lens cover External shutter) or the scene
(Shutter off) is used as thermal reference.
The normal procedure is to start with an Internal NUC. If an acceptable
image quality is not achieved, an External NUC against the lens cover or
against the scene may improve the image.
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.
