14th Color Imaging Conference - Tutorials

2-hour tutorial

Wide Gamut Colour Capture and Reproduction

Description: Broadcast television has been restricted to the Rec. 709 colour gamut for several decades; desktop graphics has used the same colour gamut - in that domain, denoted sRGB - for more than a decade. Rec. 709 and sRGB have a moderate gamut - they fail to encompass the colour range of commercial print or photographic reproduction, and fail to encompass the gamut available from consumer inkjet printers. Several display technologies are now available that have wider gamut than Rec. 709 - for example, LED-backlit LCDs. Wide-gamut display equipment is already commercially available and practical for graphics arts; wide-gamut consumer television receivers have already been introduced. We can expect wide-gamut colour to proliferate in the next several years. There are already a few wide-gamut colour encoding systems in use for specialized applications, for example, Adobe RGB 1998 for professional digital photography, and xvYCC (IEC 61966-2-4) has been standardized for broadcast. We can expect aditional wide-gamut image coding standards.

This course introduces the colour science and image science behind wide-gamut colour. We will discuss wide-gamut capture, processing, and display in professional and consumer equipment.

Course Objectives: This course will enable the attendee to:

• Understand the capture and display technologies that make wide-gamut colour practical
• Understand colour image coding for wide-gamut colour
• Understand the colour signal processing required to process wide-gamut colour

Intended Audience: Scientists; programmers; visual effects and post-production supervisors; compositors; digital imaging technicians; video, HDTV, and digital cinema engineers.

Presenter:

Charles Poynton is an independent contractor specializing in the physics, mathematics, and engineering of digital color imaging systems, including digital video, HDTV, and digital cinema (D‑cinema). While at Sun Microsystems, from 1988 to 1995, he initiated Sun's HDTV research project, and introduced color management technology to Sun. Soon after its introduction in February 2003, Mr. Poynton's book, Digital Video and HDTV Algorithms and Interfaces, was Amazon.com's 3,339-th most popular book.

Registration is between USD 150 and USD 225. For details, see the Color Imaging Conference Tutorials page.
