Abstract
According to various embodiments, the system and method of the present invention process light-field image data in a manner that reduces artifacts and that yields 2-D images with extended depth of field, and with variable placement of the center of perspective. Center of perspective can be varied based on user input or on pre-specified parameters. Various techniques for improving the presentation of light-field images with variable center of perspective are described, and for performing other effects in connection with projection of light-field images.
