What is the Light Field?

LightField Definition:
The LightField is defined as all the lightrays at every point in space travelling in every direction. It is essentially 4D data, because every point in three-dimensional space is also attributed a direction (the fourth dimension). The concept of the LightField was invented in the 1990's to solve common problems in computer graphics and vision.

How Does LightField Photography Work?
Traditional cameras – analog or digital – only record a two-dimensional representation of a scene, using the two available dimensions (length and width; pixels along the x and y axis) of the film/sensor.
Contrary to that, LightField cameras (also called plenoptic cameras) have a microlense array just in front of the imaging sensor. Such arrays consist of many microscopic lenses (often in the range of 100,000) with tiny focal lengths (as low as 0.15 mm), and split up what would have become a 2D-pixel into individual light rays just before reaching the sensor. The resulting raw image is a composition of as many tiny images as there are microlenses.
Here’s the fascinating part: every sub-image differs a little bit from its neighbors, because the lightrays were diverted slightly differently depending on the corresponding microlense’s position in the array.
Next, sophisticated software is used to find matching lightrays across all these images. Once it has collected a list of (1) matching lightrays, (2) their position in the microlense array and (3) within the sub-image, the information can be used to reconstruct a sharp 3D model of the scene.
Using this model, you have all of the LightField capabilities at your fingertips: you can define what parts of the image should be in focus or out of focus, define the depth of field, you can set everything in focus, you can shift the perspective or parallax a bit, … You can even use the parallax data to create 3D pictures from a single LightField lense and capture.
All of this can be done after you’ve recorded the image.

This is some of my raw notes, please excuse the lack of explanations.

Sony Lightfield Camera Application Promises Full Resolution Stereo Imaging

Lightfield-Forum noticed Sony patent application on lightfield camera that maintains the full image sensor resolution while providing stereo imaging. The 73-page, 43-figure US20140071244 application "Solid-state image pickup device and camera system" by Isao Hirota proposes dual level microlens and two-sided image sensor with 45-deg rotated pixels to achieve their promise:

Patent abstract:

There are provided a solid-state image pickup device and a camera system that include no useless pixel arrangement and are capable of suppressing decrease in resolution caused by adopting stereo function. A pixel array section including a plurality of pixels arranged in an array is included. Each of the plurality of pixels has a photoelectric conversion function. Each of the plurality of pixels in the pixel array section includes a first pixel section and a second pixel section. The first pixel section includes at least a light receiving function. The second pixel section includes at least a function to detect electric charge that has been subjected to photoelectric conversion. The first and second pixel sections are formed in a laminated state. Further, the first pixel section is formed to have an arrangement in a state shifted in a direction different from first and second directions that are used as references. The second direction is orthogonal to the first direction. The second pixel section is formed in a square arrangement along the first direction and the second direction orthogonal to the first direction.
