Charles Poynton

Charles Poynton specializes in the physics, mathematics, and engineering of digital colour imaging systems, including HD and digital cinema (D-cinema). He is the author of Digital Video and HD Algorithms and Interfaces, recently published in its second edition, and he is a Fellow of the Society of Motion Picture and Television Engineers (Smpte). Twenty years ago, he chose the number 1080 (as in 1920 × 1080) for HD and digital cinema standards, thereby establishing “square pixels” for HD. In 1998, he was responsible for introduction of the Adobe RGB (1998) colourspace.
