ABSTRACT:
A data-processing system is adapted to obtain data comprised of discrete data having a density different from raw data comprised of discrete data, through the interpolation. The system performs a convolution interpolation so that the noise components of the data may have a substantially uniform variance. The interpolation is performed through a coefficient calculating section and sum-of-products calculating section. The coefficient calculating section calculates the weighting coefficient of the data points of the raw data through the substitution, into a respective predetermined function, of a displacement of the data point of the raw data in the neighborhood of a respective data point of the processed data relative to the data point of the processed data. The sum-of-products calculating section performs a sum-of-products calculation of the coefficients and raw data to obtain a value of the aforementioned data.
