Claim:
1. A method of operating a plenoptic image processing system, the method comprising: storing plenoptic image data in a non-transitory computer readable memory of the system, the plenoptic image data comprising data of a plurality of microimages; applying a frequency domain transform to the stored plenoptic image data to provide a frequency domain plenoptic image data structure stored in the non-transitory computer readable memory of the system; processing the frequency domain transformed plenoptic image data structure using an extended slice technique to select a focal plane from the data structure, wherein the extended slice technique comprises taking multiple slices of the frequency domain transformed plenoptic image data structure and configuring the multiple slices to provide extended slice data; applying an inverse frequency domain transform to the extended slice data to provide inverse transform extended slice data; and providing an image output based upon the inverse transformed extended slice data.
