Claim:
A method for up-scaling an image, said method comprising: segmenting a first image into a first non-graphical region; segmenting said first image into a first graphical region; up-scaling said first non-graphical region according to a first up-scaling method; and up-scaling said first graphical region according to a second up-scaling method, wherein said second up-scaling method comprises: determining a first edge area within said first graphical region, wherein said first edge area separates a first substantially uniform region in said first graphical region from a second substantially uniform region in said first graphical region; determining a second edge area within a second graphical region, wherein said second graphical region is related to said first graphical region by a scaling factor greater than one and said second edge area corresponds to said first edge area; assigning a first value to a first pixel in a first portion of said second edge area, wherein said first value is based on a first plurality of pixel values in said first edge area; and assigning a second value to a second pixel in a second portion of said second edge area, wherein said second value is based on a second plurality of pixel values in said first substantially uniform region.
