14.6 Performing a non-uniformity correction (NUC)
14.6.1 What is a non-uniformity correction?
A non-uniformity correction is an image correction carried out by the camera software to
compensate for different sensitivities of detector elements and other optical and geomet-
rical disturbances

.
14.6.2 When to perform a non-uniformity correction?
The non-uniformity correction process should be carried out whenever the output image
becomes spatially noisy. The output can become spatially noisy when the ambient tem-
perature changes (such as from day to night operation, and vice versa).
14.6.3 Procedure
To perform a non-uniformity correction, push and hold the Image archive button
for
more than 2 seconds.
