Abstract
An adaptive pixel multisampler generates pixel data for display by using sub-pixel areas to more broadly define the space of a pixel. A sub-pixel area is defined as having a "hole" within it that is occupied by a portion of each of the adjacent sub-pixel areas. This means that while the sub-pixel areas interlock, they do not overlap which would be wasteful of memory space. Accordingly, a pixel is newly defined as extending over a larger area than a standard contiguous pixel definition of the prior art allows. The larger pixel thus provides a wider sampler area which is then used as a means for generating a higher quality anti-aliased image on the display.
