Prispevek k problematice vypoctu malych barevnych odchylek.

The lightness, chroma and hue tolerances with respect to the standard colour position in the CIELAB space were studied in detail using the various existing datasets and the set from this study. The lightness tolerance showed a clear dependency upon the metric lightness for medium to light colours, but in the case of dark colours there was a discrepancy between the datasets. Both the chroma and hue tolerances showed dependency upon both the chroma and hue-angle and not the single dependency upon the metric chroma, as assumed in the CIE94 formula. New weighting functions were derived from the above experimental evidence, and finally a new formula, MV-1 (Michal Vik Colour Difference) was proposed.Available from STL Prague, CZ / NTK - National Technical LibrarySIGLECZCzech Republi
