A camera that can see five times better than a person with 20/20 vision is here. The resolution is 50 gigapixels, or 50,000 megapixels. Cameras used by professionals reach the 40-megapixel mark, and a typical point-and-shoot might have eight or 10. The amount of information the gigapixel camera captures in a frame is nearly as much as the amount of data stored on a PC’s hard drive — all for one picture.
