3.3 EXPOSURE
Exposure describes the brightness-related parameters,
which can be adjusted by EXPOSURE MODE, AGC and
SLOW SHUTTER.
EXPOSURE MODE
You can set the EXPOSURE MODE as GLOBAL, BLC, HLC,
and WDR.
GLOBAL
GLOBAL refers to the normal exposure mode which
performs exposure according to the whole image
brightness.
BLC (Backlight Compensation)
BLC (Backlight Compensation) compensates light for the
front object 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. This function is designed
to allow camera to capture vehicle plate license at
night.
WDR (Wide Dynamic Range)
The WDR helps the camera provide clear images even
under backlight circumstances. When both very bright
and very dark areas simultaneously exist in the image,
WDR balances the brightness level of the whole image
to provide clear images with details.
AGC (Automatic Gain Control)
It optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM,
or LOW.
Note:
The noise will be amplified when the AGC is on. The
higher the level is, the more obvious the noise is.
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
