Apple Insider reports that Apple has been awarded a patent for a refocusable camera to be used with a portable device.

Apple’s U.S. Patent No. 8,593,564 for a “Digital camera including refocusable imaging mode adaptor,” describes a method in which a user can take a picture at a certain resolution and refocus the resulting image after the fact. Also noted in the patent is the inclusion of such a system in portable devices, like an iPhone.

The way Apple’s refocusable camera works is different from Lytro’s light-field camera.

Unlike Lytro, Apple’s design employs a movable adaptor situated between the lens element and the imaging sensor. The adaptor holds the microlens array, meaning the camera can operate in two separate modes: high-resolution non-refocusable and low-resolution refocuasable. Lytro’s microlens component can also be moved closer and farther from the sensor, but cannot be completely removed from the light path.
