Using Focused Plenoptic Cameras for Rich Image Capture
Todor Georgiev, Andrew Lumsdaine, Georgi Chunev · IEEE Computer Graphics and Applications · 2010
This approach uses a focused plenoptic camera to capture the plenoptic function's rich "non 3D" structure. It employs two techniques. The first simultaneously captures multiple exposures (or other aspects) based on a microlens array having an interleaved set of different filters. The second places multiple filters at the main lens aperture.
