between different color spaces. A specific color temperature will result in slightly differing RGB values, depending
on the selected color space.
White balance
o Manual
Set the RGB gains manually.
o Auto
Enable the AWB (auto white balance)
o Default gains
Default gain values for this camera model.
o sRGB D50
sRGB (standard RGB) color space with a white point of 5000 kelvins (warm light)
o sRGB D65
sRGB (standard RGB) color space with a white point of 6500 kelvins (mid daylight)
o CIE RGB E
CIE-RGB color space with standard illumination E
o ECI RGB D50
ECI-RGB color space with a white point of 5000 kelvins (warm light)
o Adobe RGB D65
Adobe RGB color space with a white point of 6500 kelvins (mid daylight). The Adobe RGB color space is larger
than the sRGB color space, but not all devices can render it.
Presets
This selection box offers several presets for common illumination types.
Temperature (Kelvin)
Here, you can set a color temperature value directly.
For color cameras, the following functions control the analog gain for the RGB color channels. The analog control is
performed in the sensor and achieve better results than software based image correction.
Red gain [0 ... 100]
Amplifies the red color values
Green gain [0 ... 100]
Amplifies the green color values
Blue gain [0 ... 100]
Amplifies the blue color values
Gamma
This function activates the gamma function and sets the factor for the gamma curve. The gamma function
emphasizes dark image areas according to a non-linear curve.
Hardware sensor gamma
This option enables gamma correction by the hardware, using a fixed factor.
