A data interpolating system by which the operating quantity can be decreased and no truncation error is produced. A data processor comprises a discrete value extracting section 10, a sampling function operating section 20, and a convolution operating section 30 so as to perform interpolation between discrete values. The discrete value extracting section 10 extracts just previous four value from successively inputted discrete data, and the sampling function operating section 20 calculates, when the data interpolating position is specified, the value of the interpolating position based on the distances between the data interpolating position and the discrete values by using a sampling function of local support which can be differentiated only once over the whole region. The convolution operating section 30 multiplies the values of the four sampling functions by the discrete values, and adds up the products, thus performing convolution operation and outputting the interpolation value.
A data interpolating system, comprising a computer, wherein a value between a plurality of discrete data is interpolated by performing convolution operation to the plurality of discrete data such as sounds and images using a sampling function that can be differentiated finite times and has values of a local support.
