1. An apparatus comprising: a buffer configured to receive a digital image, said digital image having (i) a Bayer color representation and (ii) two initial dimensions in a horizontal direction and a vertical direction respectively; and a circuit configured to generate a resample image in a signal by down-sampling said digital image in said Bayer color representation such that (i) said resample image has two resample dimensions, (ii) at least one of said resample dimensions is smaller than a respective at least one of said initial dimensions and (iii) said respective at least one initial dimension is a non-integer multiple of said at least one resample dimension.
