Exposure Mode
You can set the
EXPOSURE MODE
to
GLOBAL
,
BLC
,
HLC
, or
DWDR
.
-
GLOBAL:
Normal exposure mode, which
performs exposure according to the whole
image brightness.
-
BLC (Backlight Compensation):
Compensates
light for the front object to make it clear, but
may cause overexposure of the background,
where the light is strong.
-
HLC (Highlight Compensation):
The camera
detects the strong spots (overexposed
portions of the image), then reduces the
brightness of the strong spots to improve the
overall images.
-
DWDR (Digital Wide Dynamic Range):
Helps the
camera provide clear images even under
backlight circumstances. When both very
bright and very dark areas simultaneously exist
in the image, DWDR balances the brightness
level of the whole image to provide a clear
image with details.
SHUTTER
: Adjusts the exposure by limiting the
time over which light is admitted.
AGC (Automatic Gain Control):
Optimizes the
image clarity in poor light conditions. The
AGC
level can be set to
HIGH
,
MEDIUM
, or
LOW
.
