ISO 20462-3:2012
Photography — Psychophysical experimental methods for estimating image quality — Part 3: Quality ruler method
ISO 20462-3:2012 specifies:
the nature of a quality ruler;
hardcopy and softcopy implementations of quality rulers;
how quality rulers may be generated or obtained; and
the standard quality scale (SQS), a fixed numerical scale that may be measured using quality rulers.
