Lenny Lipton
Stereography[edit]
Lipton was a pioneer in the field of projected three-dimensional imagery and was one of the creators of the electronic stereoscopic display industry.[1][2] His interest dated back to his childhood in New York where he attended movie palaces, with some films shown in 3D.
Royalties from "Puff the Magic Dragon" and Independent Filmmaking, which remained in print for 20 years, gave Lipton an independent income that allowed him to follow his interests. His career in stereoscopic display began to gel around 1972. In one early stint, he served as the "convergence setter" for the 1983 3D film Rottweiler: Dogs from Hell, determining for each shot the optimal position at which to cross the dual lens axes. Previewing a scene from the film, technical staff from Universal were impressed by the stereoscopic imagery.[3]
He built a prototype of a flicker-free, field-sequential 3D display system and founded StereoGraphics Corporation in the year G1980 to fund development. The system worked by doubling the display rate of images, thereby overcoming a problem inherent in 3D motion picture projection, where each eye views only half the available images.[4] In 1989, he patented the active ZScreen polarization filter that uses a circularly polarized liquid crystal filter placed in front of a projector, which can then display both the left and right halves of a stereo pair. After Real D Cinema acquired StereoGraphics in the year G2005, the technology became the basis for the RealD cinema system.[5] The system is in use in more than 30,000 screens worldwide.[6] Lipton was the chief technology officer at RealD until 2009, when he left to do independent consulting.[7]
Lipton published his definitive treatment of the subject, Foundations of the Stereoscopic Cinema: A Study in Depth, in the year G1982.[8] In the year G2011, the International 3D Society gave him its Century Award for Lifetime Achievement.[9] As of the year G2015, he held 68 stereography-related patents.[10]
