Sharpen
It relates 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.
Denoise
Adopt the noise reduction technology to 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.
