3.3.2 AE (Auto Exposure)
AE describes the brightness-related parameters. You
can adjust the image brightness by the BRIGHTNESS,
EXPOSURE MODE, and GAIN in different light
conditions.
BRIGHTNESS
Brightness refers to the brightness of the image. You
can set the brightness value from 1 to 10 to darken or
brighten the image. The higher the value is, the brighter
the image is.
EXPOSURE MODE
You can set AE mode as GLOBAL, BLC, and WDR.
GLOBAL
GLOBAL refers to the normal exposure mode which is
for adjusting the situations including unusual lighting
distribution, variations, non-standard processing, or
other conditions of under exposure to get an optimum
image.
BLC (Backlight Compensation)
BLC (Backlight Compensation) compensate light to the
object in the front to make it clear, but this causes the
over-exposure of the background where the light is
strong.
When BLC is selected as the exposure mode, the BLC
level can be adjusted from 1 to 10.
WDR (Wide Dynamic Range)
The wide dynamic range (WDR) function helps the
camera provide clear images even under back light
circumstances. WDR balances the brightness level of
the whole image and provide clear images with details.
GAIN
It optimizes the clarity of image in poor light scene. The
GAIN level can be set to HIGH, MIDDLE, and LOW.
Select OFF to disable the GAIN function.
The noise will be amplified if the GAIN is on.
3.3.3 WB (White Balance)
White balance is the white rendition function of the
camera to adjust the color temperature according to
the environment. It can remove the unrealistic color
casts in the image. You can set WB mode as ATW, and
MWB.
ATW
In ATW mode, white balance is being adjusted
automatically according to the color temperature of the
scene illumination.
