1. A method of scaling an image having an original row/column resolution N O into a scaled image having a target row/column resolution N T , said method comprising the steps of: providing a filter set comprising α filters, α being equal to a quotient of said target row/column resolution N T and a common denominator k of said original row/column resolution N O and said target row/column resolution N T , said common denominator k is a positive number larger than one; for at least one row/column of image elements in said image: forming, for each filter in said filter set, a filtered image element of said scaled image by filtering a set of at least one image element in said at least one row/column using said filter; and repeating said forming step up to k times over said at least one row/column to form a scaled row/column of image elements of said scaled image.
