A Switchable Light Field Camera Architecture with Angle Sensitive Pixels and Dictionary-based Sparse Coding


We propose a flexible light field camera architecture that is at the convergence of optics, sensor electronics, and ap-plied mathematics. Through the co-design of a sensor that comprises tailored, Angle Sensitive Pixels and advanced re-construction algorithms, we show that—contrary to light field cameras today—our system can use the same measure-ments captured in a single sensor image to recover either a high-resolution 2D image, a low-resolution 4D light field using fast, linear processing, or a high-resolution light field using sparsity-constrained optimization. 1
