SDR and HDR-colour metric for optimal colour-image quality (2025), Image part hens

Title: Special colourimetric properties of colour-image technology
Calculations with the colour formula HAULAB in a wide range of
sample-viewing angle, and test and adaptation luminance
1. Introduction and goals.
2. Special colourimetric properties of colour-image technology for test samples of 4 viewing angles in white surrounds of 4 luminances;
3. Calculations with colour formulae HAULAB according to Haubner (1980);
4. Calculations for test samples with viewing angles 120' (2 degree), 60', 30', and 10' in a white surround of 180 degree;
5. Calculations for test samples in surrounds with the luminances 300, 1000, 200, and 40cd/m^2;
6. Calculation of log and lin [lightness L*, treshold delta_Y, sensitivity delta_Y/Y, contrast Y/delta_Y];
6. Application and discussion.

The following ten pages hen0 to hen9 of this chapter
show the content with links to the single figures in up to six formats.
