Reducing “Noise” in Dark Images
Adaptive noise reduction is part of the optional image processing package. (See “About
the Image Processing Package” on page 4.)
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 adaptive noise reduction (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.)
Note
ANR annotation is saved with image.
ANR off ANR enhanced
(Noise is reduced and dark areas are brightened.)
