Evaluation of a simple method for color monitor recalibration
Abstract
An algorithm for recalibrating a color monitor's RGB input-output relations is evaluated. It requires only a single measurement on an appropriatly chosen reference stimulus. Three sets of data are obtained for evaluating the algorithm's error reduction power. These relate to different ways in which the monitor can get out of calibration. Slow (but cumulative) changes over time, fast changes due to gun interaction (resulting from changed stimulus conditions), and error introduced by a different setting of the monitor's brightness control are taken into consideration. The algorithm is found to be effective in dealing with instantaneous calibration changes (gun interaction, brightness control), and for keeping track of the slow changes that may finally necessitate a full recalibration of the monitor.
