Patent ID: 8098951

Claim:
A method for modifying an image from a first sharpness to a modified image having a different sharpness: (a) receiving said image having said first sharpness; (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; (e) combining said first channel and said second channel to form said modified image having said different sharpness; and (f) where said filtered image satisfies at least one of the following criteria: (1) as a result of step (c), said filtered image is at least one of previously and subsequently scaled with a scaling filter on the image in a first channel; and (2) as a result of step (d), said filtered image is at least one of previously and subsequently scaled with a scaling filter on the image in a second channel.
