Input pixel values associated with input pixel positions having a first spacing along a direction are received and processed to determine output pixel values associated with output pixel positions having a second spacing along the direction, from respective combinations of input pixel values weighted by coefficients given by an interpolation function. In a downscaling operation, the second spacing is larger than the first spacing, and the weighting coefficients represent values of the interpolation function expanded spatially by an expansion factor equal to the ratio of the second spacing to the first spacing.
