PROBLEM TO BE SOLVED: To make the rendering range limitable and to make a system able to complete a process more quickly by making rendering shown in the context of an authoring environment and substantially maintaining the angular visual field of actual rendering and the angular visual field of abstract rendering in the same manner. SOLUTION: A render manager 310 receives a scene correction from a scene manager and selectively transfers these correction to a render engine. When the scene correction is global in property, the render manager decides scene correction data before transferring it to the render engine. When a global parameter, e.g. the marginal light intensity of a scene is corrected, the rendering of a render area part of the scene is nullified. The render manager issues a corresponding command to the render engine and commands the render engine to discontinue all kinds of rendering processes.
