Abstract
A display system includes a first storage device to store a first lightfield and a second storage device to store a second lightfield. The first lightfield comprises a two-dimensional array of images, with each image comprising a corresponding two-dimensional array of image tiles, and the second lightfield comprises a compressed representation of the first lightfield. The system further includes at least one processor configured to selectively eliminate image tiles of images of the first lightfield from inclusion in the second lightfield based on identified redundancies between the eliminated image tiles and image tiles in the same tile positions of other images of the lightfield.
