Abstract
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 a sampling function operating section and a convolution operating section so as to perform interpolation between discrete values. The discrete value extracting section extracts just previous four value from successively inputted discrete data, and the sampling function operating section 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 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.
