3-D Television A Scientific Perspective
History of 3D Imaging • 3D imaging in not new • Been around for more than 150 years • 1st patented Sir Charles Wheatstone 1838 • Stereography
3DTV Begins • “3DTV: It’s an Eye-Opener” • The first domestic 3D Television broadcast • Wednesday night 3/24/2010 • Rangers vs. Islanders NHL game • Described as “game-changing experience” Photos: multichannel.com
How 3D Works • Binocular Vision • ancient Greece – Euclid • Eyes are 2 inches apart • Each ‘sees’ slightly different picture • Brain puts it together to provide depth
