Ron Ho Mark Horowitz turned ideas into working hardware systems Enabling the Hardware for Computational Photography P rof. Mark Horowitz's work in solidstate circuits and very-large-scale integration is well known to most in the industry. However, many readers may be unaware of his fundamental contributions to the field of computational photography. He has repeatedly found opportunities to advance the state of the art by turning theoretical ideas into working hardware systems. Along the way, he mentored and guided several Digital Object Identifier 10.1109/MSSC.2016.2580282 Date of publication: 2 September 2016 52 su m m e r 2 0 16 IEEE SOLID-STATE CIRCUITS MAGAZINE students toward successful research careers. In this article, written through a series of conversations with his students, two closely related projects in the computational imaging of light fields are reviewed. The Stanford Multiple Camera Array In 1996, Prof. Marc Levoy and Prof. Pat Hanrahan presented their seminal "light field rendering" paper at SIGGRAPH. Their work described an alternative to the conventional rendering pipeline that modeled scenes with geometric shapes, colors, and textures and then simulated a camera taking a picture of that scene. They leveraged light fields 1943-0582/16©2016IEEE
