Abstract
Abstract In a system including a server to which a camera is connected, and clients which can remote-control the image pickup conditions of the camera, the server generates a message indicating a state associated with the camera control authority, and issues it to the individual clients. When each client determines that the received message is the one indicating the state associated with the camera control, it acquires the control authority status and its remained time from the received message, counts the remained time, and displays the remained time.
