Abstract
A camera control system in which operations intended by clients can be carried out by a camera server by appropriately managing and controlling every client that wishes to control a camera. Operation commands are issued to the camera server from only one client at any given time. The camera control system includes a camera server that controls a camera whose angle can be freely controlled; and a plurality of clients that control the camera and display images transmitted from the camera server on a display screen. The camera server includes a notifying unit operable when the camera server has received a control authorization acquisition request for camera control that has been issued by one client to notify the client of time information including a waiting time before the camera control is possible and a permitted control time during which the camera control is permitted for a fixed period after the waiting time has elapsed.
