Image processing system, apparatus and method in a client/server environment for client authorization controlled-based viewing of image sensed conditions from a camera

摘要

When a client control apparatus 108 on a network connects to a camera control apparatus 102 in hyper text transfer protocol and requests the camera control apparatus 102 to transmit a file of its home page, the camera control apparatus 102 transmits a file, to the client control apparatus 108, including a description for causing the client control apparatus 108 to request the camera control apparatus 102 to transmit an applet for performing automatic reception. When the client control apparatus 108 receives this file, transmission of the applet is requested, and the server control apparatus 102 transmits the applet. Then, when transmission of state information is requested, the server control apparatus 102 transmits state information to the client control apparatus 108 only when an event indicative of a change in an angle of a camera occurs; thereby traffic of the network is reduced.
