Abstract
A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.
Claims26
A continuous presence videoconferencing apparatus, comprising:
- a conferee point-of-view detector that determines a gaze of a first conferee relative to a video display associated with the first conferee;
- and
- a video editor, communicatively coupled to the conferee point-of-view detector, that builds a continuous presence video image from a video stream selected from a plurality of video streams responsive to the gaze of the first conferee.
A method of building a continuous presence video image, comprising:
- determining a gaze of a first conferee relative to a video display associated with the first conferee;
- receiving a plurality of video streams;
- selecting a video stream of the plurality of video streams responsive to the gaze of the first conferee;
- and
- building a continuous presence video image from the selected video stream.
A continuous presence videoconferencing system, comprising:
- a conferee point-of-view detector, configured to determine a gaze of a conferee and to generate a gaze information;
- a camera selector controller, configured to
- receive the gaze information;
- and
- select a video stream of a plurality of video streams received from a transmitting endpoint responsive to the gaze information.
A continuous presence videoconferencing apparatus, comprising:
- a plurality of video cameras, arranged in an arc located in a horizontal plane above a video display associated with the continuous presence videoconferencing apparatus, so that each of the plurality of video cameras captures conferees from a different angle, each configured to create a video stream;
- and
- an endpoint configured to compress the video streams created by the plurality of video cameras and generate an output compressed video stream, comprising:
- an encoder configured to compress the video streams created by the plurality of cameras into a single multi-view video stream.
