Patent ID: 8351725

Claim:
A method for modifying an image from a first scale to a modified image having a different scale: (a) receiving said image having a first sharpness at said first scale; (b) filtering said image with an image filter to result in the creation of a first channel and a second channel, wherein said first channel includes primarily texture information and said second channel includes primarily edge and flat region information; (c) filtering said first channel to attenuate higher frequency content of said image in said first channel; (d) filtering said second channel to sharpen said image in said second channel, where the filtered said second channel is at said first scale; (e) upscaling said image from said first scale to said second scale, wherein said upscaling, said filtering of said second channel, and said filtering of said first channel are based upon a plurality of the same pixels of said image from the same buffer; (f) combining said first channel, said second channel, and said image upscaled to said second scale to form said modified image having said different scale.
