ƒ Image Orientation: Changes the image orientation on the Live

ƒ Slowest Shutter Speed : Shutter speed controls the amount of the
lights enters the image sensor and directly impacts the quality of
image presentation. A slow shutter speed allows higher light
exposure that creates a brighter overall image by blurring moving
objects and bringing out background details, and a faster shutter
speed lowers color and image clarity in order to capture motions.
The minimum shutter speed ranges from 1/5 to 1/8000 sec. In low
light conditions, a fast shutter speed will lower color quality and
image clarity. In this case, select the
Auto option for automatic
shutter control or select Auto (High Speed Mode) for a faster
automatic shutter control.
ƒ D/N: Select Auto for automatic switch between day mode and night
mode depending on the amount of light detected. Select Black and
white to switch the camera to night mode. Select Color to switch the
camera to day mode. Sets the light sensor’s sensitivity of switching
between day mode and night mode. The value 10 is the most light-
sensitive. For details, see
D/N , Special View Settings , 4.1.1 Video
Settings .
ƒ Denoise: Reduces image noise especially under low-light conditions.
The higher the denoise value, the stronger the effect.
Note: For GV-EVD5100, GV-EFD5101 and GV-EBL5101, refer to the
description of Noise Reduction in 4.1.1 Video Settings.
