The human visual system has the ability to map “white” colors to the sensation of white, even though an object has different radiance when it is illuminated with different light sources. When an image is captured by a digital camera, the sensor response at each pixel depends on the illumination. That is, each pixel value recorded by the sensor is related to the color temperature1 of the light source. This application note further discusses the use and calibration of white balance, specifically for Allied Vision GigE cameras. Download the full paper for more information.
