PURPOSE:To apply presence by specifying the persons in charge of conversation (a speaker and a speaking partner) at a multi-spot video conference system. CONSTITUTION:A correlation analysis circuit 9 specifies the conversation party of its own video conference site 32 based on the strength of correlative relation between an acoustic signal (as) generated at its own video conference site 32 and acoustic signals a1-a4 generated at other video conference sites 1, 2.... A system controller 10 selects a video signal photographed by a camera close to the video display position of the specified conversation party. Thus, presence can be improved by matching glances between conversation parties each other. |
