Apple has just been awarded a patent from the US Patent and Trademark Office (USPTO) for a “Lytro-like refocusable camera”.
This system allows users to refocus an image after it has been taken, and could make its way into the cameras on upcoming iPhones.
So if you have taken a photo on your phone camera and everything was just as you wished, but the photo was ruined by being slightly out of focus, rather than having to take the photo again (when that moment may have been and gone), you can simply press a few buttons on your iPhone and have the image brought into focus.
This system would give iPhone cameras a major advantage over competitors, as blurry and out of focus images are the bane of every amateur photographers life.
