Prism Zoom™

Bigger can be better.

Prism Zoom is a scaling method for enlarging a raster computer image to three times its length and width.

Using nine spots of color to represent each pixel in the source image, the scaled images produced by the Prism Zoom algorithm are substantially sharper than those produced by general scaling methods (e.g. appearing "blocky" via nearest-neighbor or "blurry" via bilinear or bicubic interpolation).

Prism Zoom's novel approach to scaling is related to the painting styles of divisionism and pointillism: Spots of color components, drawn in close proximity, appearing—at a distance—to comprise a single spot of color.
