  • Patent number: 11631246
    Abstract: An event-based sensor having a sensing part that produces events asynchronously. The output signal includes information relating to at least some of the produced events. The method comprises: estimating a rate of production of events by the sensing part; while the estimated rate is less than a threshold, transmitting the signal having a variable rate; and when the estimated rate is above the threshold, transmitting the signal including information relating to only some of the produced events, such that a rate of events for which information is included in the signal remains within the threshold.

  • Patent number: 8107525
    Abstract: The present invention is directed to a video communication system capable of providing adaptive compression of video image data. In particular, data regarding the range of possible motions and the respective probabilities of such motion within a scene are collected, and a compression algorithm appropriate to motions having high associated probabilities selected. In response to a change in the motions and associated probabilities within a scene, a new compression algorithm can be selected. The bit rate of data transmitted by a system in accordance with an embodiment of the present invention will therefore vary, depending on the content of an imaged scene and based on the compression algorithm applied in order to compress image data while maintaining appropriate detail.

  • Publication number: 20030210326
    Abstract: The present invention is directed to overcoming the limitations of available camera angles in video conferencing applications. In particular, the present invention allows a video conference participant to select a virtual viewpoint of that participant, for providing an image to other participants. In a further embodiment, the present invention allows a video conference participant to select a virtual viewpoint of another video conference participant. The present invention provides an input device for receiving selected viewpoint information from a video conference participant. In response to a selected virtual viewpoint, the present invention transforms an image taken of a participant from an actual camera viewpoint. In accordance with a further embodiment of the present invention, multiple cameras may be utilized to obtain reference information.
