<p>A dynamically adjustable unsharp masking process for perceptually altering image edges of digitally rendered images depending on distinguishable characteristics of said images, said process comprising: generating a digitally represented blurred representation of a digitally represented original image; comparing the digital representation of said original image with the digitally representation of said blurred version of said original image to define a digital unsharp mask for said image; multiplying said unsharp mask by an adjustable weighting factor, said weighting factor being dynamically adjusted depending on said characteristics of said images for blurring edges in some image regions and emphasizing edges in other image regions; and combining said weighted unsharp mask with said original image to render an unsharped masked version of said original image. <IMAGE></p> |
