3.2 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,
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.
HLC (Highlight Compensation)

HLC stands for highlight compensation. The camera
detects the strong spots (the over-exposure portion of
image), then reduce the brightness of the strong spots
to improve the overall images.
DWDR (Digital Wide Dynamic Range)

Digital wide dynamic range gives the camera the ability
to view dark areas of the given image as well as
extremely lighted portions of the image, or areas of
high contrast.
AGC (Auto Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set to HIGH, MEDIUM,
or LOW.
Note:
The noise will be amplified when setting the AGC level.
