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. [Read more…]
