Advanced Setting
AC Frequency:
Anti-flicker setting for environment with fluorescent light sources, image sensor
needs to fit the frequency of light (power) source. For instance, the power frequency is 50Hz for most
European countries, while 60Hz is typically for US. This setting is therefore regionally different.
White Balance:
the selections for different lightening condition, which is refereeing to color
temperature.
Environment:
Select an environmental lightening. This gives an overall exposure condition.
Flicker-less Mode:
flickering can also present in various exposure level. Set “Flickerless” Mode “On”
to fix the maximum shutter speed (auto exposure control). Thus, the flickers can be eliminated.
Exposure & Gain Mode:
Select auto / manual Exposure & Gain control mode. The selection defines
the controlling in a range of or fixed value, according to the following two items (
Shutter Speed
and
Gain Value
). The configurations will be limited at selected maximum rates when AUTO mode is on.
(Max.) Shutter Speed:
referring to exposure time. Higher shutter speed is normally applied under
strong light circumstance, so the image won’t be overexposure. Lower shutter speed, on the other
hand keeps image luminance in low light environment.
(Max.) Gain Value:
the amplification factor for the incoming light. Increasing the gain value provides a
brighter image, but the noises may also be increased.
BLC:
Enable this function for image objects under backlight circumstances.
Exposure Level:
Adjust Exposure level for a target exposure time that is the amount of light allowed
for the image sensor.
NOTE
The “
Shutter Speed
”, “
Gain Value
” and “
BLC
” can be configured for daytime and nighttime. The
configurations will be applied according to the current status of “
Day/Night Mode
“.
