Three-dimensional data is compressed at a high compression ratio without deteriorating resolution and accuracy, by computing a coupling coefficient from input three-dimensional data and a three-dimensional base data group obtained from a plurality of objects and outputting the coupling coefficient as compressed data. Specifically, the three-dimensional data is input to corresponding point determination means. The corresponding point determination means generates three-dimensional data to be synthesized in which vertexes of the three-dimensional data are made to correspond to vertexes of three-dimensional reference data serving as a reference to determine association relationship between vertexes. Coefficient computation means computes a coupling coefficient for coupling a three-dimensional base data group used for synthesis of three-dimensional data to synthesize three-dimensional data to be synthesized, and outputs the computed coupling coefficient as the compressed data of the three-dimensional data.
