7.20 Performing a non-uniformity correction (NUC)

7.20.1 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 1 .

7.20.2 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).

To perform a non-uniformity correction, push and hold the Image archive button
more than 2 seconds.
