Minox shows a concept 3D camera that creates 3D images without glasses

Minox is showing a new concept 3D camera called the PX3D. They say that it can capture 3D images that are viewable without glasses. We're not sure what they mean exactly - any 3D image can be seen on a glasses-free 3D display (parallax barrier ones, for example)... so what's new here?
