It is an improvement of an existing technique based on human observation, solving its problem of numerical instability and resulting in functions in log - log scale which correspond better to the nature of display devices. We demonstrate the efficiency of our technique on different monitor technologies, comparing it with direct measurements using a spectrophotometer Contract grant sponsor: European Union (Real Reflect Project); Contract grant number: IST-2001-34744.
