Parameter
Explanation
change to be Off.
When BlackLevelAuto is set as Continues, it will continuously set
BlackLevel according to the return value of sensor.
Black level will change when the temperature rises. It is recommended to
capture a more accurate black level when the temperature is constant.
BalanceRatioSelector
Selects Red, Green or Blue channel to set white balance.
Adjusts the image color through adjusting R/G/B, in order to achieve a
highest color reproduction.
When BalanceRatioSelector is set as Off, it represents manual white
balance mode. User can manually set Red, Green, Blue channel values
in BalanceRatio.
When BalanceRatioSelector is set as Once, it represents auto white
balance mode for once. Auto white balance mode will operate for a
period and then stops according to the current scene. An algorithm for
searching gray region is used to find possible gray region in Bayer data.
When BalanceRatioSelector is set as Continues, it represents continuous
white balance mode.
White balance correction is only available for the color camera. White
balance of the mono camera defaults to 1.

Gamma
Gamma value setting.
It is a non-linear correction for image data to correct the non-linear response
of the monitor. The larger the Gamma value, the brighter the image.
The Gamma value setting range is 0
~
3.99998. The default value is 1 with
no Gamma process.

LUTControl
In this property, you can stretch and highlight the gray-level range of the region of interest. The
operation applies to linear curve as well as customized mapping curve, as shown in Figure 5-6; please
refer to Sheet 5-7 for detailed parameter settings.
LUT: short for Look-Up Table.
LUT and Gamma are mutually exclusive. If Gamma is enabled, LUT will not take effect. If LUT is
enabled, Gamma needs to be set to 1.
