Overview

The spectral components of visible lights vary according to the color temperature. The white objects have a red cast at a low color temperature or have a blue cast at a high color temperature. Human eyes can identify the actual object color based on brain reflections. The automatic white balance (AWB) algorithm is used to reduce the impacts on the actual object color exerted by external illuminants. This ensures that the captured color information is converted into the information without color cast under an ideal illuminant.
