First to third interpolation processing circuits are configured by a data identifying unit, a data converting unit, a data interpolating unit, a data reconverting unit and four switches SW 1 to SW 4 . After the data identifying unit determines a value of velocity data, the data converting unit, the data interpolating unit and the data reconverting unit switch between vector operation on a complex space based on a scalar array and vector operation on a complex space based on a color palette array and execute interpolation processing.
