areas, please select Double.

HSBLC (high spotlight backlight compensation) masks strong light sources, giving darker areas more detail. It is
often used to help identify vehicle license plate numbers, for example. Especially users can adjust and select
the special requirements area to observe the target object under the strong spots of light exist.
