PARIS — Engineers in the United States have built a prototype gigapixel camera the size of a bedside cabinet that can capture an image in a single snapshot with 1,000 times more detail than today's devices.
It is not the world's first gigapixel camera, but it is the smallest and fastest and opens up prospects for improving airport security, military surveillance and online sports coverage, its developers say.
A pixel is a small light point in a digital image, concentrations of which together form a picture.
Today's cameras capture images measured in megapixels — a million pixels — normally between eight and 40 for average consumer device. A thousand megapixels make a gigapixel.
Most of today's gigapixel images are made by digitally merging several megapixel pictures.
