Section 2, Chapter E
Colour Metrics, Differences, and Appearance (2023), Image part eecs

Title: Colourimetry of displays; colour images for visual and colourimetric spacing
1. Introduction and goals.
2. Lightnes L* according to CIE 15, and relative lightness T* according to IEC 61966-2-1 (sRGB-colour space).
3. Table data CIEXYZxy and CIELAB for three normalizations:
YW=100 according to CIE 15 & ISO/TS 28028-5 (diffuse white)
YW=90 according to ISO/IEC 15775 & ISO 9241-306,
YW=500 according to ISO/TS 28028-5 (peak white).
4. Test charts with 1080 colours, 729(=9x9x9) are equally spaced,
flower motiv with 16 equally spaced grey steps (slide and negative film) according to ISO/IEC 15775 & ISO 9241-306.
5. All test charrts with 16 relative gamma values 0,5 <= g <= 2,
Identical image with g=1 for visual test if the output appears equal (Yes/No).
6. Discussion of aplications.

The following ten pages eec0 to eec9 of this chapter
show the content with links to the single figures in up to six formats.
