Lytro camera technology: theory, algorithms, performance.

The purpose of this white paper is to introduce the Lytro light field camera. This technology is the first camera available to consumers that captures the entire light field of an image, instead of a 2D.

The light field, first described in Arun Gershun's classic 1936 paper of the same name, is defined as radiance as a function of position and direction in regions of space free of occluders. In free space, the light field is a 4D function - scalar or vector depending on the exact definition employed. Light.

Early research. The first light field camera was proposed by Gabriel Lippmann in 1908. He. Cameras available for purchase. Lytro was founded by Stanford University Computer Graphics Laboratory alumnus Ren Ng to commercialize the light field camera he developed as a graduate student there. Lytro has developed consumer light field digital cameras capable of capturing images using a plenoptic.

The plenoptic camera approach to radiance capture uses a microlens array as an imaging system focused on the focal plane of the main camera lens. This paper analyzes the performance of Lytro camera.

However, both camera arrays and LF cameras can create views that exhibit colour discrepancies, and previous work has already tackled similar issues when data is captured using the Lytro camera or multi-view camera systems. We previously proposed an L2 based colour transfer method to recolour the views of a Lytro light field to correct the colour fading that occurs on outer views of the LF.

In its CVPR paper, the project team describes a design that exploits advances in monocentric lenses, a form of lens constructed from concentric glass spheres of differing refractive index. A monocentric lens forms its image on a spherical focal surface, rather than a plane, which has the effect of avoiding many classical lens aberrations.

In this paper, we use a Lytro camera to capture the light field. A Lytro camera is the first consumer light field camera developed by R.Ng. This camera makes it possible that users capture the light field at anytime and anywhere.

Becoming Lytro. The Lytro looks unassuming enough. It is reminiscent of a kaleidoscope more than what one would traditionally consider a camera. It is a sleek square tube of colorful anodized aluminum and rubber. It is about four-and-a-half inches long and an inch-and-a-half square. At one end is a lens; at the other, an LCD screen. The Lytro.

Visual results complementing the paper are shown below. We then show in Tables 1 and 2 the average results presented in the paper. The corresponding detailed results are shown in Table 3 and 4. Lytro Illum dataset. We use in our experiments a Lytro Illum dataset consisting of light fields taken from the EPFL and the INRIA datasets.

The main aim of the project is to create and understand data from so-called light field or plenoptic cameras with a focus on the different types of plenoptic cameras: Plenoptic 1.0 (Lytro Cameras.

The camera resembles a stick of butter, but with a lens on one end and a viewfinder on the other. After clicking the shutter button, photographers can play with the focus right on the camera or move the files over to a computer for more careful tweaking. But Lytro believes that finding the perfect focus shouldn't be a single-player game. Lytro.

But Cheng concedes the Lytro will be pushed as a second camera for consumers, not a replacement for low-end point-and-shoots or full-featured digital SLRs. The average consumer will probably have fun with its refocusing ability but the Lytro also has other notable features, Cheng says, including a powerful 8X zoom, a large aperture width to allow more light into the camera, and no appreciable.
