3.2 EXPOSURE
EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, HLC,
WDR, or HLS.
GLOBAL
GLOBAL refers to the normal exposure mode that
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
over-exposure of the background where the light is
strong.
HLC (Highlight Compensation)
HLC stands for highlight compensation. The camera
detects strong spots (over-exposure portion of image)
and reduces the brightness of strong spots to improve
the overall images.
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
provides clear detailed images.
HLS (Highlight Suppression)
It is the same visual effect as the solar eclipse. If the
brightness of a part in the image exceeds the threshold,
this part will become black. Then whole image can be
clear.
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.
SLOW SHUTTER
SLOW SHUTTER increases the exposure time on a single
frame, which makes a camera more sensitive to the
light so it can produce images even in low lux
conditions.
Note:
The function is not supported by the device model with
power over coaxial (PoC) technology.
ANTI-BANDING
ANTI-BANDING is a camera setting that prevents the
appearance of horizontal lines (banding) when
photographing images in low frequency light and high
brightness environments.
