Abstract :
It is unreliable to take both full view images of a conference room and face images of speakers, in most conference room, lecture hall or auditorium of the teleconference systems. This paper, countered such special surroundings which maintained more audiences and scatted positions, analyzes the principles of mosaic camera and discusses the advantages of phase correlation methodology. Besides, the idea of mosaic teleconference camera is proposed and the implementation of the whole system is presented. Finally, we shows the evaluation results and it can substantiate the requirement.
