Abstract
A method of resolution conversion is disclosed. The method calculates a scaling factor for a first set of discrete data values compared to said second set of discrete data values. A plurality of filter function coefficients are calculated, based on the scaling factor, utilising at least one of a plurality of filter functions. The filter function coefficients are stored and later used to perform interpolation on the first set of discrete data values to generate the second set of discrete data values at a different resolution.
