EXPOSURE AGC (Auto Gain Control)
Auto Gain Control increases picture brightness in low light conditions. However, it also
increases picture noise.
Set AGC to OFF, LOW, MID, HIGH, or HIGHEST.
EXPOSURE SENSE-UP
SENSE-UP automatically activates slow shutter function when a scene is too dark.
Select a value from X2 to X1024 to set the frame integration level. The default setting is X4.
Increasing the shutter speed beyond X4 is not recommended as it may cause lagging.
Note The SENSE-UP menu cannot be controlled if the E. SHUTTER setting
is above 1/60.
EXPOSURE 3D DNR
Digital Noise Reduction reduces the noise/distortion on the screen in night mode, allowing
clear images in low light conditions.
Set 3D DNR to OFF, LOW, MID, HIGH, or SMART (recommended).
SMART optimizes the DNR volume depending on the scene.
