Abstract:
A device to reconstruct acoustic data and animation data in synchronization by compressing or expanding a pair of acoustic data and animation data that are in synchronization, comprising:a data segment dividing part dividing a series of acoustic data and a series of animation data into a plurality of segments; a parameter time series determining and creating part determining and creating at least one of a power of a sound extracted from the acoustic data, a parameter representing a pitch of the sound, spectrum data extracted from the acoustic data, and motion vectors extracted from the animation data, as a variable parameter time series that determines a degree of compression or expansion of the acoustic data and the animation data of each of the segments divided by the data segment dividing part; an input frame dividing part to further divide the acoustic data segments into equal interval input frames; an output frame length determining part determining an output frame length of the acoustic data based on the parameter time series determined by the parameter time series determining and creating part; an acoustic animation synchronous data output part outputting a correspondence table for synchronous points between the acoustic data before compression or expansion and the acoustic data after compression or expansion with respect to the acoustic data to be compressed or expanded based on the parameter time series determined by the parameter time series determining and creating part; an acoustic data reconstructing part compressing or expanding the acoustic data of the input frames based on the output frame length; and an animation data reconstructing part compressing or expanding the animation data based on the correspondence table.
