NUC

Non-uniformity correction

CAMCUDA WIKIUpdated 29 October 20262 min read

Correction that reduces response differences between detector pixels.

What it means

Real detector pixels do not have identical responses. Non-uniformity correction compensates for these differences to reduce fixed-pattern structure in the image.

NUC can use stored correction data and updated references. Some cameras obtain a uniform reference by moving a shutter in front of the detector, which may briefly interrupt fresh scene acquisition.

In practice

Integration note

Check correction timing and image behaviour under changing module temperature, especially when continuous fresh frames matter.
