Patent ID: 7068286

Claim:
A computer-implemented method of processing video data to be displayed on a display device having horizontal resolution h 1 and vertical resolution v 1 , wherein the video data has horizontal resolution h 2 and vertical resolution v 2 , wherein the video data comprises a plurality of scan lines, wherein at least one scan line has at least one line span representing the projection onto that scan line of a graphics vector rendered in the video data, and wherein the graphics vector has a slope and the line span has a color and a width, the method comprising: for a resultant video data set having a horizontal resolution less than h 2 , determining a color of an edge resultant pixel in a resultant scan line using, at least in part the slope of the graphics vector at an edge sub-pixel; and directing the resultant video data set toward the display device; wherein determining a color of an edge resultant pixel comprises: determining whether the slope is greater than or equal to 0.4 and whether the edge sub-pixel is at an even location; and based at least in part upon the determination, determining the color of the edge resultant pixel to be 25% of a color of an immediately adjacent prior sub-pixel plus 75% of the line span color.
