This Technical Specification normalizes evaluation and grading of a light coding system used fordisplays and display systems, but is independent of the display technology. This procedure measureswhether an observer can distinguish between an uncompressed reference and the reconstructed imageto a pre-determined, statistically meaningful level.The procedure compares individual images with two possible forced choice comparison test methods.This procedure relies on subjective evaluation methods designed to discern image imperfections onelectronic colour displays of any technology or size.Image selections for testing a specific coding system has bearing on the results this procedure willyield, but specific images required for testing are not within scope, excluding an informative annexdescribing self-test certification. Image categories may vary between end-usage products. Forexample, content relevant to television manufacturers may or may not be relevant to computer displaymanufacturers. Due to the nature of this procedure as a visual psychophysical test, observer’s age isconsidered a meaningful parameter of the results.
