Definition
Color constancy is the ability to perceive colors as approximately constant even though the light entering the eye varies with the illuminant. Color constancy also names the field of research investigating the extent of this ability, that is, the conditions under which a color is actually perceived as constant and which factors influence color constancy. Computer scientists working in the field of color constancy try to mimic this ability in order to produce images which are independent of the illuminant, that is, color constant. Simple color-constancy algorithms, also known under the name automatic white balance, are used in digital cameras to compute a color-corrected output image. The input of a color constancy algorithm is often one image taken under an arbitrary illuminant and the output of a color constancy algorithm is frequently the image as it would appear had it been taken with a canonical illuminant such as CIE Standard Illuminant D65 or a spectrally uniform...
