3.1.1. EXPOSURE MODE
You can set the EXPOSURE MODE to GLOBAL, BLC, or WDR.
• GLOBAL refers to the normal exposure mode, which
adjusts lighting distribution, variations, and non-
standard processing.
• BLC (Backlight Compensation) compensates light to
the object in the front to make it clear, but may cause
overexposure of the background where the light is
strong.
• WDR (Wide Dynamic Range) helps the camera provide
clear images even under backlight circumstances.
WDR balances the brightness level of the whole
image and provides clear images with details.
3.1.2. AGC (Auto Gain Control)
AGC optimizes the clarity of the image in poor light
conditions. The AGC level can be set as HIGH, MEDIUM, or
LOW. Select OFF to disable the AGC function.
NOTE:
Noise will be amplified when the
AGC
is on.
3.1.3. 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 conditions.
