overcranking

A team of researchers Lausanne Polytech’s Laboratory of Engineering Mechanics of Soft Interfaces are developing a method to reconstruct detailed slow-motion videos from blurry still photographs.
The title references the cinematic term for capturing extra frames, hand-cranking the camera at a faster than normal rate, but playing it back at speed. Whereas formerly blurred photos were chiefly caused by being out of focus, the autofocus speeds of modern cameras have eliminated that and instead the problem is one of shutter speed, with the smeared image captured as an action shot. As of now the method only can reverse-engineer high-contrast vignettes but could one day interpolate and forensically rebuild entire scenes.
