Observer 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 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. ...
متن کاملAnalysing observer metamerism in CIECAM02 using real observers
Given a fixed set of viewing conditions, a colour appearance model provides a method for transforming tristimulus values to perceptual attributes correlates, and vice versa. Current colour appearance models, like CIECAM02 [1], have been developed assuming the CIE31 Standard Observer. However a general model must adequately describe the colorimetric behaviour of a large enough set of real observ...
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 کاملModeling 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,...
