This paper describes an accurate method to obtain the Tone Reproduction Curve (TRC) 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 effiency of our technique on different monitor technologies, comparing it with direct measurements using a spectrophotometer.
