YOUR CAMERA HAS ONE LENS and takes two-dimensional photographs.
But what if your digital camera saw the world through thousands of tiny lenses, each a miniature camera unto itself? You'd get a 2-D photo, but you'd also get an electronic depth map that contained the distance from the camera to every object in the picture-a kind of super 3-D.
Stanford University electronics researchers, led by Abbas El Gamal, an electrical engineer, are developing such a camera built around their multi-aperture image sensor. The plan is to create a camera that takes pictures that are really detailed depth maps, invisible in the photograph itself but electronically stored along with it. The map is a virtual ...
