ABSTRACT:
A picture display system in which a plurality of applications each render a window W on a single display includes a picture server. The picture server calculates a re-rendering range O of a window W, based on the movement, enlargement or contraction of the window W, and outputs a re-rendering request to each application rendering the window W in the re-rendering range O. With the applications, each rendering the windows W only in the re-rendering range O, the load of the re-rendering processing becomes lighter.
