Claim Text:
1. An antialiasing image generation apparatus for performing antialiasing processing and generating a graphics image on which the antialiasing processing has been performed, the antialiasing processing being performed for smoothly displaying a polygon that is in three-dimensional space having a depth represented by a Z value when a three-dimensional image constituted by the polygon is rendered in a two-dimensional plane, the antialiasing image generation apparatus comprising: a processor; and a non-transitory memory having stored thereon executable instructions, which when executed, cause said processor to perform: wherein said selecting includes (i) determining a threshold value using the average value acquired in said acquiring, (ii) when the Z value included in the pixel data is the same as the threshold value or smaller than the threshold value, selecting a first antialiasing technique, and (iii) when the Z value included in the pixel data is greater than the threshold value, selecting a second antialiasing technique that requires a smaller number of calculations per pixel than the first antialiasing technique.
