■ Sharpness: Adjust the image sharpness level, which ranges from 0% to 100%.
■ Gamma curve: Adjust the image sharpness level, which ranges from 0.45 to 1, from Detailed to
Contrast. You may let firmware Optimize your display or select the Manual mode, and pull the slide bar
pointer to change the preferred level of Gamma correction towards higher contrast or towards the higher
luminance for detailed expression for both dark and lighted areas of an image.
■ 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.
You can click on Restore to recall the original settings without incorporating the changes. When
completed with the settings on this page, click Save to enable the setting.
The following applies to a fixed-focal lens module:
■ Enable low light compensation: Select this option in low light mode, and the values of sharpness and
brightness will change automatically. This function also benefits from an automated noise reduction
feature.
■ WDR enchanced: This function allows users to identify more details of objects in the high contrast
environment especially for details in the shaded area. You may check the Enable WDR enhanced
checkbox, and then adjust the sensitivity (low, high) and the strength (low, medium, high) to reach the
best image quality.
