Description
Mode
Device exposure modes.
●
Auto: Adjusts the image brightness according to the actual condition
automatically.
●
Aperture priority: The iris value is set to a fixed value, and the Camera
adjusts shutter value then. If the image brightness is not enough and
the shutter value has reached upper or lower limit, the system adjusts
gain value automatically to ensure the image at ideal brightness.
●
Shutter priority: When the exposure range is normal, the system
prefers the configured shutter range when auto adjusting according
to the ambient lighting condition. If the image brightness is not
enough and the shutter value has reached upper or lower limit, the
system adjusts gain value automatically to ensure the image at ideal
brightness.
●
Gain Priority: When the exposure range is normal, the system prefers
the configured gain range when auto adjusting according to the
ambient lighting condition. If the image brightness is not enough and
the gain has reached upper or lower limit, the system adjusts shutter
value automatically to ensure the image at ideal brightness. You can
configure gain range to adjust gain level when using gain priority
mode.
●
Manual: Configure gain and shutter value manually to adjust image
brightness.

Basic NR
Select the
On
checkbox to enable this function. Aiming at single-frame
image, 2D NR averages the pixel points (points that are with image noise)
with other common pixel points to decrease the image noise and achieve
an acceptable and good image display effect. The higher the grade, the
better the noise suppression effect.
Advanced NR
Select the
On
checkbox to enable this function. Aiming at multiple-frame
image, 3D NR handles information between two frames to reduce the
image noise. The higher the grade, the better the noise suppression effect.
