NOTE: This function is supported only by certain devices equipped with a motorized lens.
The image edge will be lost if this function is enabled.
• BLC
If you focus on an object against a strong backlight, the object will be too dark to be seen clearly. BLC
(backlight compensation) compensates light to the object in the front to make it clear. If BLC mode is
set to
Custom
, you can draw a red rectangle on the live view image as the BLC area.
• WDR
WDR (Wide Dynamic Range) provides clear images in environments with strong illumination
differences.
When there are both very bright and very dark areas simultaneously in the field of view, enable the
WDR function and set the level. WDR automatically balances the brightness level of the whole image
and provides clear images with more details.
NOTE:
When WDR is enabled, some other functions may be not supported. Refer to the
actual interface for details.

according to the environment.

level means stronger reduction degree.
