ABSTRACT OF THE DISCLOSURE A method of and apparatus for mapping digital video sample values from a first sample domain to a second sample domain using a mapping function which involves a change in image size, for example, for a digital video effects unit, is disclosed. The apparatus comprises an address generator and a processor for computing, for each sample position in the second sample domain, the position of a point in the first sample domain which using the mapping function would map onto that sample position in the second sample domain, and an interpolator for obtaining from available input sample values an interpolated sample value for that point in the first sample domain, the interpolated sample value being used as the sample value for that sample position in that second sample domain.
