Accurate display gamma functions based on human observation Neumann, Attila Artusi, Alessandro Neumann, László Zotti, Georg Purgathofer, Werner Visualització (Informàtica) Information display systems Terminals de pantalla de visualització Video display terminals This article describes an accurate method to obtain the tone reproduction curve of display devices without using a measurement device. 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.
