Reducing "Noise" in Dark Images

Adaptive Noise Reduction (ANR) is part of the image processing package. (See
the Image Processing Package"
When the probe is in a dark area, the live image is often noisy, or grainy ("crawling pixels").
You can improve such images by turning on ANR in either of two modes:
• ANR normal — Reduces noise without any brightening.
• ANR enhanced — Reduces noise and brightens dark areas. (Does not brighten areas
that are already bright.)
