Apple's late co-founder and CEO Steve Jobs was reported to be keenly interested in the technology and invited the inventor of the Lytro to visit his home for a private demonstration before the technology went public. Lytro does have an app in the Apple App Store and Nokia recently introduced a feature called Refocus for its PureView camera equipped phones. The patent was filed by Apple in 2011.
Lytro is listed as prior art in Apple's patent application, but the tech titan says improvements can be made in both picture quality and resolution. Apple's technology differs from Lytro's as it employs two separate modes. One is a high-resolution non-refocusable mode and the other is a low-resolution refocusable mode. The patent also covers an add-on version for any existing camera. Apple might consider using the technology for the video capture feature on a future iPhone model.
