Measurement Window
: This function allows users to configure measurement window(s) for low
light compesation. For example, where low-light objects are posed against an extremely bright
background, you may want to exclude the bright sunlight shining through a building's corridor.
■ Full view: Calculate the full range of view and offer appropriate
light compesation.
■ BLC: When selected, a BLC window will appear on screen meaning that the center of the scene
will be taken as a weighed area. This option enables light compensation for images that are too
dark or too bright to recognize; for example, for the dark side of objects that is posed against
bright sunlight.
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.
