An empirical-parametric gamma calibration algorithm

preprint2014arXivOpen access

Abstract

A method to determine the gamma correction curves for displays is presented. An empirical model is first constructed from exhaustive measurements of a few representative units. The model parameters for the remaining units are then fitted using only a few measurements. The method uses standard least-squares algorithms and is computationally light. Experimental results for a small sample of LCD displays are presented.
