Abstract
A camera control system capable of controlling a video camera of a camera server apparatus according to a control command from clients is arranged not to accept requests for a right to control the video camera from any of clients when the number of clients receiving a video image picked up by the video camera exceeds a predetermined number. If the number of clients is less than the predetermined number, the camera control system, upon receipt of a request for the control right from any of clients, accepts the request to permit the client to control the video camera.
