Abstract
A client/server system includes a client and a plurality of servers which are connected via a communication network. The client includes an object-oriented middleware and client-form image processing objects. A middleware processing device converts a client-form request from a request input device into a standard-form request readable by the middleware. A request transmitting device transmits the standard-form request to the network. Each of the servers includes an object-oriented middleware, image processing units, and image processing objects. The image processing objects of each server have specific interfaces to the image processing units, any one of the image processing objects allowing a corresponding one of the image processing units to be executed in response to a server-form request. A middleware processing device of the server converts the standard-form request from the network into a server-form request, and transmits the server-form request to a selected one of the image processing objects so that a corresponding one of the image processing units is executed in response to the server-form request.
