Abstract

Digital cameras have the concept of white balance, which defines the ambient lighting conditions by assigned a colour temperature to the most prevalent ambient lighting. Modern cameras have automatic white balance functionality, however, this does not always work accurately because there may simply not be sufficient information in the photograph. This can be overcome by recording white balance information when the camera is switched on, regardless of whether it is taking a photograph, and using this historic data to generate a more accurate figure for the final image.
