MIT's Technology Review reports Bell Labs Invents Lensless Camera "Today, this revolution gains pace because Gang Huang and pals from Bell Labs in New Jersey say they’ve used compressive sensing to build a camera that needs no lens and uses only a single sensing pixel to take photographs. What’s more, the images from this camera are never out of focus."

I’m not sure I get it. It seems having to take multiple snap shots (and at the 1:4 compression ratio the example suggests millions of shots) is a huge drawback. Generally speaking it is much easier to make a larger electronic array than a faster one. If you just want in-focus/long depth-of-field pinhole lenses are great for that (and you could use the post processing to counteract the characteristic distortion).
