Modeling Observer Variability and Metamerism Failure in Electronic Color Displays
The electronic display industry has begun a migration towards higher color gamut devices driven by LED, OLED, quantum dot and laser technologies capable of generating near monochromatic color stimuli in the traditional red, green, blue three-channel paradigm. The use of highly selective spectral stimuli, however, poses a risk to the consistency of visual experience amongst a group of disparate,...
متن کاملObserver Metamerism Models and Multiprimary Display Systems
Television and cinema display are both trending towards greater ranges and saturation of reproduced colors made possible by near-monochromatic illumination technologies. Through current broadcast and digital cinema standards work, system designs employing laser light sources, narrowband LED, quantum dots and others are being actively endorsed in promotion of Wide Color Gamut (WCG). However, spe...
متن کامل(How) Do Observer Categories Based on Color Matching Functions Affect the Perception of Small Color Differences?
In this paper we investigate the impact of colorimetric observer categories on the prediction of the average suprathreshold color difference perception. The observer categories were obtained from an observer classification experiment, while the color difference data were obtained from an experiment involving a liquid crystal display (LCD) with fluorescent backlight. The same observer panel with...
متن کاملMean Observer Metamerism and the Selection of Display Primaries
Observer metamerism is an unavoidable fundamental limitation of colorimetry. While standard observers might provide accurate estimates of population-mean color matching functions, they can never predict accurate matches for all individual observers. This limitation is minimized in applications where the spectral difference (or potential for metamerism) is small. This is typically when original ...
متن کاملToward Reducing Observer Metamerism in Industrial Applications: Colorimetric Observer Categories and Observer Classification
The variability among color-normal observers poses a challenge to modern display colorimetry because of their peaky primaries. But such devices also hold the key to a future solution to this issue. In this paper, we present a method for deriving seven distinct colorimetric observer categories, and also a method for classifying individual observers as belonging to one of these seven categories. ...
