ABSTRACT:
System and method for scaling the size of a digital image from a first digital image to a second digital image by a specified scaling factor of G. The apparatus comprises an interpolator module configured to magnify the first digital image by a first scaling factor G1. The interpolator is further configured to output an intermediate digital image indicative of the magnified first image. The apparatus further comprises a shrinking module configured to shrink the intermediate digital image outputted by the interpolator module by a second scaling factor G2 to thereby generate the second digital image. Scaling factor G2 is a power of two.
