ΔICtCp Color Difference Metric

While the various ∆E color difference metrics, specifically ∆E00, have served well for assessing perceptual color differences in standard dynamic range (SDR), the introduction of high dynamic range (HDR) and wide color gamut (WCG) technology raised the question of whether these metrics were still applicable with these new capabilities.

Innovations In 3D Colour LUT's for Display Calibration

Color science expert Charles Poynton and SpectraCal software developer Joel Barsotti provide an explanation of the varying methods used to interpolate 3D LUTs for the calibration of video displays. This paper was presented at IBC 2014 in Amsterdam.

BT.1886 - 10 Questions, 10 Answers

Since the International Telecommunication Union (ITU) adopted BT.1886 as the recommended gamma function for flat panel displays used in HDTV studio production in 2011, some confusion has arisen over the usefulness of the function, as well as its application in the field.

Why Viewing Angle is Important

A meter’s viewing angle is not really something we need to be concerned about when dealing with transmissive illuminate displays, like flat-screen TVs, since the meter is typically either in direct contact with the screen or very near it.

ΔEITP is Now ITU-R BT.2124 - Is the Industry Ready to Move on From ΔE2000?

Objective color difference metrics are the main tools for evaluating the color accuracy of professional reference monitors in the content creation industry. They are also vital for consumers who calibrate their displays with a desire to maintain the creators' intent when viewing films, TV shows, and even the latest video games. Accurate predictions of perceptual color differences are essential to providing a realistic evaluation of a device’s color reproduction.
