Paper Abstract

Digital light field photography consists of recording the radiance along all rays (the 4D light field) flowing into the image plane inside the camera, and using the computer to control the final convergence of rays in final images. The light field is sampled with integral photography techniques, using a microlens array in front of the sensor inside a conventional digital camera. Previous work has shown that this approach enables refocusing of photographs after the fact. This paper explores computation of photographs with reduced lens aberrations by digitally re-sorting aberrated rays to where they should have terminated. The paper presents a test with a prototype light field camera, and simulated results across a set of 35mm format lenses.
