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 so that 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 notifying means that have
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.
