Backlight Settings
BLC (Back Light Compensation)
If there’s a bright backlight, the subject in front of the backlight appears silhouetted or dark. Enabling the BLC
(back light compensation) function can correct the exposure of the subject. However, the backlight
environment will be washed out.
WDR (Wide Dynamic Range)
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.
The user can enable or disable the WDR function as shown in Figure 6-30. The wide dynamic level ranges from
0 to 100.
