Patent ID: 7333141

Claim:
A method of resampling a data sequence to resize a digital image, comprising: (a) providing filter coefficients according to an input resembling ratio U/for resizing a digital image where U and D are positive integers, said coefficients grouped into U sub-filters according to phase and corresponding to a data access block; (b) for each of a plurality of architecture kernels: (i) provide a step per group of H of said sub-filters from a first set of integers about H*D/U where H is the height of said architecture kernel; (ii) for each of said steps from said first set, find a length for said sub4i/ters according to an access coverage chart for said data access block; (c) using the architecture kernel and the step corresponding to a minimum of said lengths of step (b)(ii) to filter an input digital image data sequence; (d) outputting the filtered digital image to a storage medium or a display.
