Patent Images
1. An image distribution system comprising:
- a server including an image sensing unit;
a client device for receiving an image picked up by the image sensing unit via a network;
control means for controlling an operation of the image sensing unit;
command issue means for issuing a function request command from the client device to the control means;
judging means for judging a communication status of the network; and
display control means for displaying a user interface, wherein the user interface includes selectable indicators depending on a quality of the communication status of the network judged by the judging means, the selectable indicators consisting of buttons and scroll bars, allowing the function request command to be performed with a fine granularity of control commands of pan, tilt or zoom, when the quality of the communication status of the network is higher than a predetermined level, and when the quality of the communication status of the network is lower than the predetermined level, changing the user interface such that the selectable indicators for performing the function request command with a fine granularity of the control commands are no longer displayed, and instead, the selectable indicators consist of one or more buttons allowing limited pan, tilt or zoom operations with preset values determined in the server according to the communication status of the network.

Abstract
An image distribution system, which is connected via a network with a client for displaying an image picked up by an image sensing unit of a server, judges a communication status of the network. In addition, in accordance with a result of the judgment, the image distribution system changes a user interface for selecting a function request command for the image sensing unit of the imaging apparatus.
