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.
White Balance
White balance is the white rendition function of the camera. It is used to adjust the color
temperature according to the environment.
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.
