NR (Noise Reduction)
2D & 3D NR are very sophisticated and powerful noise reduction technologies at low light.
2DNR
The process of removing image noise from a video signal by applying a
digital comb filter
3DNR
A 3D filter reduces the noise caused by movement resulting in less blur.
Too strong 3DNR reduction results in the tail effect of a comet or motion blur form a fast moving
target in low light.
