Abstract

A light field data acquisition device includes optics and a light field sensor to acquire light field image data of a scene. In at least one embodiment, the light field sensor is located at a substantially fixed, predetermined distance relative to the focal point of the optics. In response to user input, the light field acquires the light field image data of the scene, and a storage device stores the acquired data. Such acquired data can subsequently be used to generate a plurality of images of the scene using different virtual focus depths.

First claim

What is claimed is:

1. A light field imaging device for acquiring light field image data of a scene, the device comprising:
optics, wherein the optics includes an optical path and a focal point, wherein the focal point is associated with a focal length of the optics;
a light field sensor, located (i) in the optical path of the optics to acquire light field image data and (ii) at a substantially fixed, predetermined distance relative to the focal point of the optics, wherein the…
