Researchers have developed a way to create a 3D image through a single lens, without moving the camera.
The technology could allow amateur photographers and microscopists to create the impression of a stereo image without using expensive hardware. It could also provide a cheaper method to create 3D films for the big screen.
The technique, developed at the Harvard School of Engineering and Applied Sciences, relies only on computation and mathematics, rather than costly equipment.
The method, named ‘light-field moment imaging’, takes two images from the same camera position but focused at different depths. The slight differences between these two images provide enough information for a computer to mathematically create a brand-new image as if the camera had been moved to one side.
