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.

higher level means stronger reduction degree.

You can enable the defog function when the environment is foggy and the image is misty. It

enhances the subtle details so that the image appears clearer.
