Noise reduction
■ Enable noise reduction: Check to enable noise reduction in order to reduce noises and flickers in
image. This applies to the onboard 3D Noise Reduction feature. Use the pull-down menu to adjust
the reduction strength. Note that applying this function to the video channel will consume system
computing power.
3D Noise Reduction is mostly applied in low-light conditions. When enabled in a low-light condition
with fast moving objects, trails of after-images may occur. You may then select a lower strength level
or disable the function.
