Compressive Light-Field Camera: Next Generation in 3D Photography


Consumer photography is undergoing a paradigm shift with the development of light field cameras. Commercial products such as those by Lytro and Raytrix have begun to appear in the marketplace with features such as post-capture refocus, 3D capture, and viewpoint changes. These cameras suffer from two major drawbacks: major drop in resolution (converting a 20 MP sensor to a 1 MP image) and large form factor. We have developed a new light-field camera that circumvents traditional resolution losses (a 20 MP sensor turns into a full-sensor resolution refocused image) in a thin form factor that can fit into traditional DSLRs and mobile phones.
