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
