Notable piece in the New Scientist about how “blurry” photo snaps may be a thing of the past now that a digital camera is being developed by a Stanford team to refocus photos after they have been taken.
The piece has frustratingly little on when camera will be ready, but here’s a blurb:
The camera could be useful for action shots taken by sports photographers or for CCTV surveillance cameras, which often produce fuzzy shots due to poor lighting.
..Now, Pat Hanrahan and his team at Stanford University have figured out how to adjust the light rays after they have reached the camera….Software can then be used to adjust these values for each microlens to reconstruct what the image would have looked like if it had been properly focused. That also means any part of the image can be refocused – not just the main subject.
