<P>PROBLEM TO BE SOLVED: To provide communication equipment for transmitting and receiving video images corresponding to demand of a participant at a receiving side in a remote conference, and a conference system. <P>SOLUTION: A transmitting side conference terminal generates the whole image (still image) with the whole conference room as a photographing area and transmits the whole image to the opposite side conference terminal in advance. When a conference is started, the transmitting side conference terminal specifies the direction of a sound source (speaker) by a microphone array, generates moving video representing an area (any of areas B, C and D in figure) associated with the sound source direction specified in a photographing area of a web camera and transmits the moving video to the opposite side conference terminal. The opposite side conference terminal displays the received moving video in a corresponding area in the whole image. By the above processing, an image area including a participant speaking at that time is displayed with the moving video, and at the same time, the whole image is not updated about no speaking participants and a background. Consequently, necessary information can be transmitted and received without using a network band excessively. <P>COPYRIGHT: (C)2009,JPO&INPIT |
