ColorTemperature

Description

ColorTemperature sets the color temperature for auto white balance. You can fix a setting (in kelvins) for the color temperature of an image when you are using a color camera. The function will use the sensor's hardware gain controls for the setting, as far as possible.

Using RGBColorModel you can choose between different color spaces. A specific color temperature will result in slightly differing RGB values, depending on the selected color space.

Hinweis

The color temperature is the temperature to which a black body radiator has to be heated to glow and give off light in the corresponding color. Warm light (reddish) has a lower color temperature than cold light (bluish). The following table lists a few example values:

Light source	Color temperature
Light bulb (100 W)	2800
Halogen lamp	3200
Fluorescent lamp (cold white)	4000
Morning and evening sunlight	5000
Noon sunlight	5500-5800
Flash strobe	6000
Overcast daylight	6500-7500
Fog	8000

Achtung

This function cannot be used simultaneously with the automatic white balance function.
