“Gain”
In the slide bar of Gain, there are also two sliders, which represent the limitations
to control the maximum gain value and the minimum one, respectively. Normally,
the minimum value is to 1x for better quality. It is not allowed if the maximum
slider and the minimum one are set to the same value without adjustable interval.
Besides, the noise will be increased if the actual gain is too large. When the max.
slider is dragged over sensor's max. gain, the slide bar will become deep blue to
represent it will apply Mozart 3s digital gain, which extend the max. gain for very
low light.
“Shutter Speed”
There are 2 fields, minimal and maximal time, for the range of Shutter Speed.
The precision of the parameter is 1/1000000 sec., but it is NOT actual precision
of the shutter speed of the sensor. The actual precision of the shutter speed
depends on each sensor’s specification. Here it will be rounded to approach
sensor’s effective exposure time. To avoid flickering or banding phenomenon
under fluorescent light, the actual shutter speed will be locked at 1/120, 1/60,
1/30 if Power Line Frequency is 60Hz, or 1/100, 1/50, 1/25 if Power Line
Frequency is 50Hz. The setting of Power Line Frequency is on the sub-tab Video
and Audio. The exposure may not be stable if the maximum value and the
minimum one are set to the same value without adjustable interval. Besides, the
frame rate will drop down if the actual shutter speed is too slow to meet expected
frame rate.
Noise reduction
Provides 2D and 3D features.
Wide Dynamic Range
Enable Wide Dynamic Range auto in different level to improve the exposure
when both bright and dark areas simultaneously in the field of view of the camera.
The default is off.
