A patent granted to Apple today for a Light Field camera – a camera with zero shutter delay and where the focus point can be changed after taking the photo – covers the precise technology Steve Jobs told biographer Walter Isaacson he wanted to use to “reinvent photography.”

He had three things that he wanted to reinvent: the television, textbooks and photography.

Jobs met with Lytro CEO Ren Ng in the summer of 2011, was shown a demo of the company’s Light Field camera and said that that he wanted the company to work with Apple … 

The patent refers to a “refocusable imaging mode adaptor,” and the abstract perfectly describes a Light Field camera:

A digital camera system configurable to operate in a low-resolution refocusable mode and a high-resolution non-refocusable mode comprising: a camera body; an image sensor mounted in the camera body having a plurality of sensor pixels for capturing a digital image; an imaging lens for forming an image of a scene onto an image plane, the imaging lens having an aperture; and an adaptor that can be inserted between the imaging lens and the image sensor to provide the low-resolution refocusable mode and can be removed to provide the high-resolution non-refocusable mode, the adaptor including a microlens array with a plurality of microlenses; wherein when the adaptor is inserted to provide the low-resolution refocusable mode, the microlens array is positioned between the imaging lens and the image sensor.

Sections of the patent reference prior art, likely a reference to the work done by Lycos in this area.


We’ve often said that we don’t cover most Apple patents because the company patents all kinds of things for all kinds of reasons, with very few of them making it into Apple products. If you tried to use Apple patents to predict future product releases, you’d be both very disappointed and very confused.

This one, too, may come to nothing. But when it plays directly into something that interested Steve Jobs enough to consider it a reinvention of photography, we can probably be pretty confident that the technology has, at the very least, been examined very, very closely by Apple.

Of course, wanting to do it and being able to are two different things. Fitting a Light Field camera into something as slim as an iPhone is probably best described as ‘challenging.’ But we’ll certainly be keeping our ear to the ground on this one.

If you want to play with the technology yourself, Lytro has an interactive gallery online. Pick a photo, then simply click where you want to focus.
