Publication number: 20170257601Abstract: A synchronization device synchronizes cameras capturing a multi-view session. In particular, the synchronization device receives a respective capturing parameter for each of a plurality of individual cameras, and selects a multi-view capturing parameter, to be used in capturing a multi-view session, that matches with the capturing parameters of at least some of the individual cameras. The synchronization device selects at least two cameras, from the plurality of individual cameras, suitable for capturing the multi-view session using the multi-view capturing parameter, and notifies the selected cameras to start capturing the multi-view session at respective times using the multi-view capturing parameter.Type: ApplicationFiled: May 24, 2017Publication date: September 7, 2017Inventors: Daniel Catrein, Frank Hartung, Markus Kampmann, Thomas Rusert

Patent number: 9699418Abstract: Synchronizing cameras, connected via a telecommunication network, for capturing a multi-view session can be controlled by a synchronization module. The synchronization module determines a multi-view capturing parameter from a capturing parameter that is received from at least one camera. The multi-view capturing parameter is provided by the synchronization module to the cameras participating in the capturing session in order to synchronize the capturing of the multi-view session. Further, a camera device informs the synchronization module of the disposability and capturing parameter of the camera. The camera receives the multi-view capturing parameter for use in capturing the session.Type: GrantFiled: November 17, 2009Date of Patent: July 4, 2017Assignee: TELEFONAKTIEBOLAGET LM ERICSSON (PUBL)Inventors: Daniel Catrein, Markus Kampmann, Thomas Rusert, Frank Hartung
