The Magic Eye Book Craze of the 1990’s! An autostereogram is a single-image stereogram (SIS), designed to create the visual illusion 3D scene from a 2D image.

Every pixel is computed from a pattern strip (wallpaper image) and a depth map (negative version of the image to emerge). A hidden 3D image emerges when viewed with the right vergence (almost cross-eyed).

For a stronger experience and better viewing pleasure, sit closer to the 3DTV.
3D image processing is also a little harder on our brains, so it’s best to be sitting whilst watching one of these
