Abstract
Abstract A retractable video teleconferencing apparatus for a video monitor having an optical axis. An optical assembly includes a housing mounted to the video monitor; a track for moving the housing between a retracted position and a forward position in which the housing is positioned forward of the video monitor; a beamsplitter hingedly attached to the housing and movable between a first position in which the beamsplitter is positioned across the optical axis at an angle relative thereto, whereby optical images directed toward the display along the optical axis are at least partially reflected by the beamsplitter, and a second position in which the beamsplitter is retracted into the housing; and a video camera located in the housing and positioned relative to the beamsplitter for receiving the partially reflected images and for generating a video signal corresponding to the partially reflected images. The beamsplitter, in the first position, is mounted at a 45° angle relative to the optical axis. An adjustable bracket secures the track to the video monitor. The housing may include a pair of retractable wings extending laterally therefrom to block out stray light. An opaque panel positioned below the beamsplitter and hinged thereto blocks stray images from the beamsplitter.
