Zusammenfassung:An image display system (100) wherein a plurality of applications (10) render a window (W) on a single display (50). This system includes an image server (20), which calculates, based on the shift, scale-up and scale-down of the window (W), a re-rendering range (O) of the window (W), and outputs a re-rendering request to the application that currently renders the window (W) in the re-rendering range (O). The application (10) re-renders the window (W) only in the re- rendering range (O), thereby reducing the load of the re-rendering processing.
