摘要

Procedure for calculating camera parameter presets corresponding to participants (Part A, Part B, Part C) in a videoconferencing system, said procedure comprising: - providing a camera having parameters (50) of rotation, tilt and zoom; - define a space based on a distribution of said videoconferencing system; performing one of - moving said camera through all the relevant rotation values, said relevant rotation values being defined by said space in which said videoconferencing system is located, and - zooming out in said camera in such a way that all possible participants can be seen through said chamber and in such a way that a location of each participant in said space can be determined; - detect and label said participants to obtain labeled participants within that space; - calculating said presets corresponding to said labeled participants, said presets defining a camera view, said presets based on at least one of: (i) an optimal position of said labeled participants in said camera view, (ii) an alignment from the center of a head of said participants labeled with a center of said camera view, and (iii) an alignment of a center of a participant labeled with said center of said camera view; and - update the presets associated with a particular tagged participant if you have changed a location of the particular tagged participant, being the continuous, periodic update, or when a new preset is selected.
