Abstract
A teleconferencing system (100, 100') provides a wide aspect ratio view at each site utilizing a single NTSC camera (250, 350) and projector (260,360). At the transmitting end of a teleconference, a transformation element (280, 380, 510, 610) maps a wide aspect ratio field of view into the field of view of an NTSC camera. The transformation is reversed at the receiving end of the teleconferencing system.
