Adobe Plenoptic Lens Keeps Photos Always in Focus

Adobe has created a new system for computational photography that uses a plenoptic lens to capture subjects. What makes this particular set up different is that it can capture a subject and then process the photograph afterwords to get the correct part of the picture in focus.

The image that is captured uses a bunch of tiny lenses to capture the image each focusing in a different part of the scene. The example in the image above shows a girl in front of some trees. The image can be processed to show either the girl in focus or the trees in focus or even anything else seen in the picture in focus.

The plenoptic lens sits in front of the sensor and is a collection of lenses. When light passes through it, the sensor picks up a bunch different perspectives of an image of which each are captured by the sensor in a single sweep. These fragments of the scene can then be put together through rendering to produce an image focused as you want it.

All the lenses give the image an infinite depth of field leaving the user to choose afterwards, what needs to be processed and focussed on. This type of technology could be handy for anybody as any image could be captured and then adjusted back in to focus at the correct point afterwards.

Check out the video below to see a demonstration of how the image is captured, what the stored image looks like and what the results are.
