Patent ID: 7213214

Claim:
A method for generating a presentation of a region of interest within an original image for display on a display screen, comprising: transforming said original image with a distortion function to produce an initial presentation, said distortion function having a focal region for said region of interest at least partially surrounded by a shoulder region in turn being surrounded by an external region, said distortion function having a magnification being uniform for said focal region and varying for said shoulder region such that said distortion function is continuous from said external region through said shoulder region to said focal region; providing means for selecting a parameter for adjusting said distortion function; receiving said parameter through said means; wherein said parameter adjusts said distortion function by at least one of: increasing said magnification such that said focal region fills said display screen; increasing said magnification such that said focal and shoulder regions fill said display screen; and, applying said magnification uniformly to said focal, shoulder, and external regions; adjusting said distortion function with said parameter and transforming said original image with said adjusted distortion function to directly produce and define content for said presentation; and, displaying said presentation on said display screen.
