System and method for scaling images

A system for calculating a target pixel for scaling an image comprising a plurality of source pixels, said system comprising:

• (a) a plurality of calculation units for calculating values for a first set of predetermined parameters;
• (b) a filter selector for selecting a filter tap configuration from a set of filter tap configurations in accordance with said fist set of predetermined parameters, said set of filter tap configurations including non-linear filter tap configurations;
• (c) a convolution unit for convolving selected ones of said plurality of source pixels along a locus of said selected filter tap configuration with predetermined weighting factors;
• and
• (d) an output for combining said convolved pixels for calculating said target pixel.

A method of scaling an image comprising a plurality of source pixels, said method including The steps of:

• (a) determining a contour in said image using at least one of a set of predetermined parameters;
• (b) selecting a first target pixel, said first target pixel being a target pixel closest to said determined contour;
• (c) setting said first target pixel equivalent to a closest source pixel on said contour;
• and
• (d) filtering said plurality of source pixels for determining a second target pixel.
