A graphical user interface (GUI) which displays a map image showing the location
of a camera whose sensed image is distributed via a network, and further displays
a camera icon indicative of the position and states of the camera on the map image.
When a user designates an area desired to be sensed on the GUI after the user obtains
authorization to control the camera, control values for controlling facing direction
and the angle of view of the camera are calculated. The calculated control values
are transmitted to a camera server via the network, and the camera server controls
the camera on the basis of the control values.
