A moving image reproduction unit (104) generates display object information for each of a plurality of frames, using difference information for each object associated with each frame and reproduces a moving image. An analysis unit (102) analyzes the difference information for each frame and determines a frame attribute that is an attribute of the frame. When a frame other than a head frame of the plurality of frames is specified as a reproduction start frame from which the reproduction of the moving image starts, the moving image reproduction unit (104) extracts one of the plurality of frames based on the frame attribute determined by the analysis unit (104). Further, the moving image reproduction unit (104) generates display object information of the reproduction start frame, using the difference information of the frame extracted and the difference information of the reproduction start frame, and starts the reproduction of the moving image from the reproduction start frame.
