HLC
When the bright area of the image is over-exposed and the dark area is under-exposed, the HLC
(High Light Compression) function can be enabled to weaken the bright area and brighten the dark
area, so as to achieve the light balance of the overall picture.
WDR
The WDR (Wide Dynamic Range) function helps the camera provide clear images in environment
with strong illumination differences.
When there are both very bright and very dark areas simultaneously in the field of view, you can
enable the WDR function and set the level. WDR automatically balances the brightness level of the
whole image and provides clear images with more details.
Note
When WDR is enabled, some other functions may be not supported. Refer to the actual interface
for details.
DNR
Digital Noise Reduction is used to reduce the image noise and improve the image quality. Normal
and Expert modes are selectable.
Normal
Set the DNR level to control the noise reduction degree. The higher level means stronger
reduction degree.
