Patent ID: 7379072

Claim:
A method for displaying an image on a display, the image comprising at least one pixel, the method comprising: determining weighting factors for a color calculation of a color value of texels for a footprint of the at least one pixel, the footprint covering a plurality of texels in a texel grid, wherein determining the weighting factors comprises: (a) determining form information of the footprint; (b) determining edges of the footprint; (c) approximating the edges determined in step (b) by a staircase function; (d) determining the texels of the texel grid contacted by the staircase function; and (e) determining a weighting factor for each texel containing a portion of the staircase function depending on a subarea of the respective texel covered by the footprint; wherein an enlargement offset (r) is associated with the footprint, wherein following step (a), based on the enlargement offset, the footprint is enlarged by offsetting the edges of the footprint outwardly from current edge footprint positions by a distance depending on the enlargement offset, wherein the offset edges are determined in step (b), wherein the offset edges are approximated in step (c) by a staircase function, and wherein in step (e) a weighting factor for each texel containing an offset edge is determined depending on the subarea of the respective texel covered by the enlarged footprint; and calculating a pixel color on the basis of the determined weighting factor; and outputting the pixel color for generating a representation of the pixel on the display.
