Shoot a picture first, focus later
Now this is interesting. Pat Hanrahan and his team at Stanford have managed to devise a system to refocus an image in a digital camera before it’s recorded.
They inserted a sheet of 90,000 lenses, each just 125 micrometres across, between the camera’s main lens and the image sensor. The angle of the light rays that strike each microlens is recorded, as well as the amount of light arriving along each ray.
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.
Great for the professional sports photographers, but will just make the creative photographers more lazy. :) Then again, the refocusing is driven by software, which you could no doubt reverse engineer and hack. Could prove for some interesting shots. :D
