ABSTRACT
Edward Adelson and James Bergen defined the plenoptic function as a record of the 3D distribution of light rays and their dependence on parameters such as wavelength and polarization. Most research on these ideas has emphasized the 3D aspect of plenoptic-function capture and manipulation, paying less attention to other parameters. A new approach leverages the focused plenoptic camera's high-resolution and flexible-sampling trade-offs to perform high-resolution capture of the plenoptic function's rich "non 3D" structure. This approach employs two techniques. The first simultaneously captures multiple exposures with a microlens array having an interleaved set of different filters. The second places multiple filters at the main lens aperture. Experimental results validate the approach, producing 1.3-megapixel high-dynamic-range images with one capture.
