BS ISO/IEC 29170-2:2015 normalizes evaluation and grading of a light coding system used for displays and display systems, but is independent of the display technology. This procedure measures whether an observer can distinguish between an uncompressed reference and the reconstructed image to 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 on electronic colour displays of any technology or size.Image selections for testing a specific coding system has bearing on the results this procedure will yield, but specific images required for testing are not within scope, excluding an informative annex describing self-test certification. Image categories may vary between end-usage products. For example, content relevant to television manufacturers may or may not be relevant to computer display manufacturers. Due to the nature of this procedure as a visual psychophysical test, observer's age is considered a meaningful parameter of the results.Cross References:ISO 3664ISO 9241-302ISO 20462-1ISO/IEC PD/TR 29170-1ISO/CIE 11664-6CIE S 014-6/EITU-R BT.500All current amendments available at time of purchase are included with the purchase of this document.
