This invention allows a user to simultaneously control geometric parameters for a camera and suppresses a deterioration in the image quality of distributed video images while keeping the cost low. The invention includes an image sensing area calculation unit for calculating a minimum image sensing area including required areas from clients, a required video image forming unit for forming required video images by extracting video images of the respective required areas from a video image of the image sensing area which is sensed, and a video image transmission I/F for distributing the formed required video images to the respective clients. Only the minimum area including the respective required areas is sensed, and video images of the respective required areas are cut from the video image and distributed to the respective users, thereby allowing a plurality of users to simultaneously control the camera and obtain video images at desired viewpoints and view angles. In addition, since only one camera is used, the required cost can be kept low, and the electronic zoom magnifications of video images to be distributed can be suppressed low, thereby minimizing a deterioration in the image quality of each required video image.

This invention provides an information sharing system management apparatus which efficiently manages a TV conference without requiring the user to join it. When a terminal A is started, a first system acquires information such as the start time, participants, and the like of a video conference system from that video conference system, and transmits the acquired information to a second system on a terminal A . The second system stores the received information. When the operator inputs a conference record command on the terminal A , the first system requests the video conference system to send a conference record including speech and the like, and transmits the received conference record to the second system. The second system stores the received conference record. The operator at the terminal A can display and observe the conference information and conference record stored by the second system as needed. Such information is updated every required times.

When an object region of data has been assigned through an input unit, an object assigning unit writes the assigned object in a picture surface information region in an assigned object information region. When a cutting command has been input, the assigned region is stored in a nonshared clipboard region or a shared clipboard region according to instruction by the command. A shared clipboard is connected to shared clipboards of other systems via a shared clipboard communication unit. When a position has been assigned and a pasting command has been input, a pasting processing unit takes out data from an assigned clipboard, and connects the data to the assigned position. Thus, an operation of cutting and pasting data between systems is simplified.
