• Brightness: Set the brightness level of the camera's image.
• Contrast: Set the color difference between the brightest and darkest
parts.
• Hue: Set the total color degree of the image.
•
Saturation: Set the degree of color purity. The purer the color, the
brighter the image is.
• Sharpness: Set the resolution level of the image plane and the
sharpness level of the image edge.
• Noise Reduction: Decrease the noise and make the image more
thorough. Increasing the value will make the noise reduction effect
better but it will reduce the image resolution.
• Backlight Compensation (BLC):
o
Off: Disables the backlight compensation function. It is the default
mode.
o
HWDR: WDR can adjust the camera to provide a better image
when there are both very bright and very dark areas
simultaneously in the field of the view by lowering the brightness
of the bright area and increasing the brightness of the dark area.
The recording will be stopped for a few seconds while the mode
is changing from non-WDR to WDR mode.
o HLC: Lowers the brightness of the entire image by suppressing
the brightness of the image's bright area and reducing the size of
the halo area.
