: We show that the plenoptic camera is optically equivalent to an array of cameras.
We compute the parameters that establish that equivalence and show where the plenoptic
camera is more useful than the camera array.

1. Introduction
In 1908, Lippmann introduced the idea of using a microlens array to capture the radiance of a scene and produce what
he called integral photographs [1]. These photographs dis yed not just a 2D picture, but also “the 3D relief” of the
scene [2]. In 1928, Ives subsequently added an objective lens to Lippmann’s microlens array [3] to rease the acuity.
S e then, many other researchers and scientists have to advance integral photography.
With the advent of digital photography, significant new opportunities to investigate integral photography became
available. In 1992, Adelson introduced the “plenoptic camera,” a digital version of Lippmann’s microlens array de-
signed to solve problems omputer vision [4]. In 2005, Ng improved the plenoptic camera and introduced new
digital-processing methods, luding refocusing [5, 6]. In later work Fife [7] and Lumsdaine and Georgiev [8] im-
proved the resolution by introducing the focused plenoptic camera and developed methods for rendering synthetic
views with computational focus at high resolution.
In parallel with this, researchers have also used arrays o
