3.3 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE as GLOBAL, BLC, or
DWDR.
 GLOBAL
GLOBAL refers to the normal exposure mode which
adjusts lighting distribution, variations, and non-standard
processing.
 BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light to the
object in the front to make it clear, but this may cause the
over-exposure of the background where the light is
strong.
 DWDR (Digital Wide Dynamic Range)
The digital wide dynamic range helps the camera provide
clear images even under backlight circumstances. WDR
balances the brightness level of the whole image and
provides clear images with details.
AGC (Auto Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM,
or LOW. Select OFF to disable the AGC function.
Note:
The noise will be amplified when the AGC is on.
