Meaning
Brightness
It is the brightness level of the camera’s image.
Contrast
It is the color difference between the brightest and darkest parts.
Saturation
It is the degree of color purity. The color is purer, the image is brighter.
Hue
It refers to the total color degree of the image.
Sharpen
It refers to the resolution level of the image plane and the sharpness level of the
image edge.
Wide Dynamic
The wide dynamic range (WDR) function helps the camera provide clear images
even under back light circumstances. When there are both very bright and very
dark areas simultaneously in the field of view, WDR balances the brightness level
of the whole image and provide clear images with details.
BLC
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.
BLC: If enabled, the auto exposure will activate according to the scene so that the
object of the image in the darkest area will be seen clearly.
