Abstract
The present invention provides a system, apparatus and method for filtering an image that produces output images having high resolution without visual discontinuity across a wide range of resize ratios. The invention includes a linear filter for source images requiring low magnification and a higher order filter for source images requiring high magnification. In the transition region an interpolation is performed between the linear and higher order filters to provide a smooth transition in filtering and magnification to produce an output image.
