2-hour tutorial
The color gamut of digital imaging systems, in both the professional and consumer domains, has historically been limited by CRT technology and by the BT.709 and sRGB standards. Emergent display technologies (such as LED-backlit LCDs and laser- and LED-illuminated DLPs) are poised to enable wide-gamut color, and D-SLR cameras are already capable of wide-gamut capture. The emergence of these display technologies brings new challenges in how to capture wide-gamut color, and how to transform between wide gamut and moderate gamut representations at origination equipment, and at display equipment. Deployment of wide-gamut color in consumer electronics is particularly challenging; there is a huge distribution infrastructure, and there are trillions of “legacy” images. How is the existing infrastructure to be adapted? How are legacy images to be treated? And how are new, wide-gamut images to be displayed on legacy devices? The course outlines the color science and color image coding issues behind wide gamut capture and reproduction. It describes why cameras are inherently wide-gamut. The course also outlines the color transforms necessary to optimize classical colorimetry, and explains how color transforms interact with the picture rendering transforms that are a part of all commercial imaging systems. A discussion of several wide-gamut standards including
Adobe RGB 1998 (IEC “opRGB,” for graphics arts), SMPTE/DCI P3 R’G’B’ and X’Y’Z’ (for digital cinema), and xvYCC (for broadcast television) is included.
Benefits: This course will enable the attendee to:
Intended Audience: appropriate for technical professionals who are experienced in the engineering of color imaging systems. Many graphs, equations, and diagrams will be presented.
Presenter:
Charles Poynton is an independent contractor specializing in the physics, mathematics, and engineering of digital color imaging systems, including digital still cameras, digital video, HDTV, and digital cinema (D-cinema). He does technology forecasting, systems modeling, algorithm development (including digital filter design), video signal processing architecture, color characterization and calibration, and image quality assessment. He is involved in engineering wide color gamut (wide colour gamut) systems, including xvYCC.
Registration is between USD 150 and USD 210. For details, see the Color Imaging Conference Short Courses page.
