Physiologically Personalized Color Management for Motion Picture Workflows

Abstract

<italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">One of the essential mechanisms employed by the human visual system when interpreting the natural world is that of trichromatic integration of physical scene spectra by cone photoreceptors. By extension of this, different scene spectra can result in the same color sensation to an observer, a phenomenon known as metamerism. This allows imaging systems to produce realistic reproductions of scene content by the same three-channel mechanism. To predict these matches, color matching functions (CMFs) are used, which aim to describe the average spectral integration behavior of observers. However, the use of a single average observer CMF has been shown to result in impactful color rendering errors, as there exists significant variation in the spectral absorption characteristics of the eye within populations of color-normal observers. When this is crossed with the growing disparity between the spectral characteristics of emerging display technology, it becomes evident that this interobserver variability needs to be taken into account</i> .
