Abstract

In image sharing systems where work is carried out in collaboration by a plurality of computers connected via a network sharing an image, problems occur where results displayed for content of operations for each terminal do not coincide.

In the image sharing system of the present invention, a synchronization server is added to a related image sharing system, and the occurrence of mismatches in content displayed at the images of each image sharing terminal are resolved by sending content of operations of each image sharing terminal to a synchronization server once so as to bring about synchronization.

Claims

1. An image sharing system for displaying a shared image at a plurality of computer display devices connected via a network, and provided with a synchronization server connected to the plurality of computers via the network,

wherein the synchronization server comprises:

receiving means for receiving content of operations carried out at the plurality of computers;

accumulating means for accumulating and assigning order in order of receipt to received operation content; and

distribution means for distributing operation content accumulated at the accumulating means to the plurality of computers in the order of accumulation.

2. The image sharing system of claim 1, wherein the accumulating means of the synchronization server accumulates content for operations received from the plurality of computers in such a manner as to assign order in units of elements comprising content displayed at display devices of the plurality of computers.

3. The image sharing system of claim 1 or claim 2, wherein the distribution means of the synchronization server receiving content of operations adds identification information for identifying which operation of “

distribute to all of the plurality of computers connected via the network”

, or “

distribute to all of the computers connected via the network excluding the computer sending to the synchronization server”

is to be performed as attribute information for the operation content for content of each operation of the plurality of computers received by the synchronization server.

4. The image sharing system of any one of claims 1 to 3, wherein each of the plurality of computers connected via the network are provided with operation content transmission means for delaying transmission of operation content to the synchronization server according to content of the operation.

5. The image sharing system of any one of claims 1 to 4, wherein the plurality of computers connected via the network are either customer operated terminal devices of a financial institution or terminal devices operated by an operator.

6. The image sharing system of any one of claims 1 to 4, wherein the plurality of computers connected via the network are either personal computers of customers carrying out on-line shopping connected to the internet or computer terminals operated by operators of a merchant-side help desk.
