We’re a little confused. A recent report has announced a super small camera which is the size of a ‘coarse’ grain of salt, which sounds great. The camera, developed by Princeton and Washington Universities appears to be quite a miraculous feat of engineering. The key fact is that it’s not only small, but produces images of much higher quality than previous tiny cameras have before. So far so cool. But what’s causing us no end of confusion is the fact that there’s another team of boffins, which have created something which looks similar called a ‘NanoCam’. This too is an incredibly small camera, and it also seems to use similar technology, removing the lens in favour of some sort of tubular layout. It’s hard to work out which device works better or has more utility, but how interesting to see them both of them slugging it out for the small camera prize.
