Three-dimensional data (120) 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 (130). Specifically, the three-dimensional data (120) is input to corresponding point determination means (101). The corresponding point determination means (101) generates three-dimensional data to be synthesized (103) in which vertexes of the three-dimensional data (120) are made to correspond to vertexes of three-dimensional reference data (111) serving as a reference to determine association relationship between vertexes. Coefficient computation means (102) computes a coupling coefficient for coupling a three-dimensional base data group (112) used for synthesis of three-dimensional data to synthesize three-dimensional data to be synthesized (103), and outputs the computed coupling coefficient as the compressed data (130) of the three-dimensional data (120).
