In the seminal 1996 paper Light Field Rendering, Levoy and Hanrahan describe a representation for light fields that allows for both efficient creation and display. This representation provides a way of generating novel rendered views of a 3-D scene using a 4-D data structure.

What is light field display?

Light Field Displays (LFDs) work by chopping up the image volume radially, a bit like a cake. This is unlike volumetric displays, which slices the volume like a loaf of bread. LFDs typically have an angular separation of around one degree between slices.

How does light field work?

The light field is a vector function that describes the amount of light flowing in every direction through every point in space. The space of all possible light rays is given by the five-dimensional plenoptic function, and the magnitude of each ray is given by its radiance.

What is a Lytro camera?

The Lytro camera is the first consumer camera that records the entire light field-all the rays of light traveling in every direction through a scene-instead of a flat 2D image. Shoot first, focus later By capturing the light field, you can do incredible things. Like refocus pictures after you take them.

What happened to the Lytro camera?

Futuristic “light field” camera maker Lytro is shutting down, according to a statement posted online. The company says that starting today, it will stop “taking on new productions and providing professional services,” as it prepares to “wind down” the company over an unspecified period of time.

Implementing a Light Field Renderer

Who invented Lytro camera?

Ren Ng is the 32-year-old inventor of the Lytro camera, a device he hopes will come to revolutionize the field of digital photography.

When did the Lytro camera come out?

The Lytro company started in 2006 and brought its first consumer-model camera to the market six years later. Despite the impressive tech, the company had struggled recently, as it shifted its attention more to the field of virtual reality and 360-degree image capture.

What is light field video?

The Light Field Video Camera is an array of CMOS image sensors for video image based rendering applications. The device is designed to record a synchronized video dataset from over one hundred cameras to a hard disk array using as few as one PC per fifty image sensors.

What is field of view camera?

Field of view (FOV) is the open, observable area a person can see through their eyes or via an optical device, such as a camera. In the case of optical devices, FOV is the maximum area that the device can capture.

What is near field camera?

Description: Near field profiling can also be used with camera profilers to analyze small beams, and involves a microscope objective lens to image the beam onto a camera detector array.
