Harry Potter fans who watched enviously as the schoolboy wizard wielded magical time-freezing binoculars will soon be able to buy their own super spyglasses. For designers at Sony have invented binoculars that allow users to pause, rewind and play back whatever they are viewing. The digital devices reminiscent of the 'Omnioculars used by Potter to watch his favourite sport of Quidditch could revolutionise birdwatching, horse racing, cricket and even opera. The technology also allows music fans to record and watch concerts in 3D, while recording the sound in stereo. Sony says its 'Vinoculars or video binoculars are the first devices of their kind in the world. Unlike conventional models which rely on two sets of lenses side by side to make distant objects appear closer, the hi-tech version captures images using two miniature cameras positioned in parallel.
