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.

How does Lytro camera work?

A Lytro image -- the proprietary image file is called a Light Field Picture or LFP file -- contains information about the light field for that picture. Essentially, the software creates a virtual lens and sensor, simulating what would happen if you were to have physically changed the focus on a traditional camera.

Can you still use Lytro camera?

Living pictures will still work in Lytro's desktop app, but in order to share photos taken with the company's cameras going forward, users will have to export them as . mov, . gif, or static JPGs.

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.

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.

Why Light Field Cameras are Hard

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 light field technology?

A light field camera, also called a plenoptic camera, is a camera that uses a micro-lens array to capture 4D light field information about a scene. The micro-lens array is placed between the main lens ( at, before, or after the focal plane) and the camera sensor.

How do I reset my Lytro camera?

Choose “Reset” from the menu: NOTE: On newer versions of the camera firmware (software), you will need to scroll down the menu (swipe up on the touchscreen) to reveal the Reset option.

What are light field cameras used for?

A light field camera, also known as a plenoptic camera, is a camera that captures information about the light field emanating from a scene; that is, the intensity of light in a scene, and also the precise direction that the light rays are traveling in space.

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 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.

What does focal length determine?

Lens focal length tells us the angle of view—how much of the scene will be captured—and the magnification—how large individual elements will be. The longer the focal length, the narrower the angle of view and the higher the magnification.

What is light field VR?

Much different from the displays used in VR and AR headsets today, light-field displays generate an image that accurately represents how we see light from the real world. Specifically, light-field displays support both vergence and accommodation, the two focus mechanisms of the human visual system.

Why do you need a NFC camera?

Near Field Communication (NFC) is a technology which enables contactless communication between devices which are equipped with this technology. With NFC-compatible Nikon cameras, Wi-Fi capability of the camera can easily be activated by simply touching an NFC-compatible smart phone to the camera.

What does NFC mean on a camera?

NFC (Near Field Communication) is an international standard for shortrange wireless communications technology. If the smart device supports NFC (Near Field Communication), a Wi-Fi connection can be established simply by touching the camera N-Mark logo to the smart device NFC antenna.

What is the difference between near field and far field?

The key difference between near field and far field is that near field is a region that is close to an antenna or a scattering object whereas far-field is the region that occurs at a distance from the antenna or the scattering object.

At what distance from the antenna does the far field start?

It is widely stated in the antenna literature that the far field of an antenna operating in free space, where all the above properties must hold, starts from a distance of 2*D*D/wavelength, where D is the maximum dimension of the antenna.

How far is far field?

The far-field distance is the distance from the transmitting antenna to the beginning of the Fraunhofer region, or far field.

What is considered far field?

Far Field or Fraunhofer Region. The far field region is the most important, as this determines the antenna's radiation pattern. Since antennas are used to communicate wirelessly from long distances, this is the region of operation for most antennas. We will start with the Far Field.

What is the difference between NFC and Wi-Fi?

In a nutshell, it is a proximity-based wireless communication standard. Unlike Wi-Fi or Bluetooth, however, NFC interaction is limited to an extremely short range. Besides smartphones, you can sometimes find NFC on tablets, speakers, collectibles, and even gaming consoles like the Nintendo Switch and 3DS.

What can NFC be used for?

NFC is the technology in contactless cards, and the most common use of NFC technology in your smartphone is making easy payments with Samsung Pay. NFC can also be used to quickly connect with wireless devices and transfer data with Android Beam.
