Exposure control:
■
Exposure level: You can manually set the Exposure level, which ranges from -2.0 to +2.0 (dark
to bright). You can click and drag the semi-circular pointers on the Exposure time and Gain
control slide bars to specify a range of shutter time and Gain control values within which the
camera can automatically tune to an optimal imaging result. You may prefer a shorter shutter
time to better capture moving objects, while a faster shutter reduces light and needs to be
compensated by electrical brightness gains.
■ Flickerless
: This function helps avoid the flickering on images because of the fast shutter
movement and the inconsistency between power line frequency (50 or 60Hz) and exposure time.
When selected, the exposure time will be forced to stay longer than 1/120 second. For cameras
that come with fixed iris lens, setting the exposure time to longer than 1/120 second may
introduce too much lights to the lens. Users can use this option to observe whether the result of
long exposure time is satisfactory.
