■ Sharpness:
Adjust the image sharpness level, which ranges from -3 to +3.
You can also select
Customize and manually enter a value.
■ Gamma curve: This function is for user to
select a proper gamma curve value to adjust the gray-scale of
the monitor.
■ Enable low light compensation: Select this option in low light mode, and the values of sharpness and
brightness will change automatically as the noise reduction function.
WDR enhanced:
This function allows users to identify more image details with an extreme contrast from
an object of interest with one shadowed side against a bright background, e.g., an entrance. You may
select the Enable WDR enhanced checkbox, and then adjust the sensitivity (low, high) and the strength
(low, medium, high) to reach the best image quality.
You can click Preview to fine-tune the image, or click Restore to recall the original settings without
incorporating the changes. When completed with the settings on this page, click Save to enable the
setting.
