I think it's much more complicated than that. From another news source:
"Whereas a normal digital camera captures a snapshot of light hitting a sensor, a light field camera first separates rays of light in order to individually record their color, intensity and direction. This extra information opens up a world of possibilities, including the ability to focus on any depth of field within a taken photo, observe a 3D-type effect even without specs, and boost images taken in extremely low light."
Definitely cutting-edge and novel, imo.
