Anybody know about this new-fangled plenoptic camera?
'Because so much light is captured in a single image, you don’t need to worry about focusing when you shoot your picture — you can focus an image after the fact. Lytro calls this resulting interactive photograph a “living picture.” '

Is this for-real new-tech, or just a gimmick?

This is kind of cool.
So does "micro-lens array specially adhered to a standard sensor" mean the "raw" image is kind of a "fly eye" view, like a zillion little pictures of the same image? Would each micro lens have the same focus, and just the offset (optical parallax) changes from lens to lens; or each lens have a different focus?
"The Light Field Engine travels with every living picture as it is shared, letting you refocus pictures right on the camera, on your desktop and online." sounds like processing software is built into image.

Is this something we can reproduce with "micro lens array" and a prop (or array of props); or is this more in the realm of a DSP chip?
I'm thinking of some kind of robot vision sensor application.
edit - thanks for the link to the dissertation. Some light reading while the kids play at the park today!
What would be neat is if the chip could derive a stereo pair from the image although, given the lens size, it would only be useful for macro 3D images.
