PROBLEM TO BE SOLVED: To compose a three-dimensional CG picture, actual video data and sound data with presence in a multimedia information presentation system using a computer. SOLUTION: An information presentation system 3 capable of composing and displaying a three-dimensional CG picture and actual video data, and a dynamic image representation device 1 for generating a representation video enhanced in the feeling of continuity of three-dimensional CG picture and the actual video data by incorporating contents extracting three-dimensional information on an object projected from the actual video into the coordinate system of a three-dimensional CG picture are provided to enable composite display without causing any incompatibility. Moreover, a sound representation device 2 for allowing a user to recognize existence of data which do not exist within the display range of a screen is provided to more facilitate the user operation such as retrieval of an information presentation space by outputting sound related to the data by the volume or orientation matched with the information presentation space.
