Duke engineers improve camera resolution - mcclatchydc

 If you brought your fancy new digital camera instead, the picture will be better, but the players will still be plagued by pixels.

Soon this may no longer be a problem. A team led by David Brady, professor of electrical engineering at Duke University, has created a camera, called AWARE-2, that is 50 times better than your digital camera. And according to a paper on their work published recently in Nature, they also have demonstrated they can make a camera thousands of times better.

The recipe? Make a bunch of cameras cooperate.

“We wanted to make an analogy with computers,” says Brady. “People kept trying to make computer processors faster and faster. Only recently did we realize parallel, multiple processors did the trick. You don’t need better ones, just more, working together.”

Your cellphone camera is probably about 1 megapixel, meaning each image it captures has 1 million pixels. If the image is square, it’s a grid with 1,000 spaces on a side, each filled with color to result in a picture.

A DSLR camera, the best kind of consumer camera, gets about 20 times more pixels in the same image, giving finer detail.

The strange thing is, your cellphone camera is outperforming your DSLR, in a sense. A cellphone camera can only, theoretically, capture about a megapixel because of the size of its lens opening, or aperture. Meanwhile, your DSLR has an aperture 10,000 times the size of your cellphone camera, meaning it should be able to capture 10 billion pixels. But current DSLRs capture less than 1 percent of that number.
