started accepting pre-orders for the world's first camera, which records the light field.

In standard digital cameras, the light rays reflected from objects that fall into the lens and then onto a flat light-sensitive matrix consisting of millions of pixels. The result is a two-dimensional image with a resolution equal to the matrix resolution.

The cell

Lytro another principle. It operates not pixels, and the rays of light, recording the color, intensity and direction of the rays at each point in space. With this user does not need to focus on the object - the focus point can be chosen arbitrarily on the finished image and change it, considering the various parts of the image.

Since the camera does not focus system, it has no motor, so shooting is instantaneous, and the errors of automatic or manual focus are excluded.

founder and CEO Ren H impressed by the gigantic plants at Stanford University, consisting of dozens of cameras for recording light fields, in 2006 in his Ph.D. thesis presented a method of reducing the system to tiny size, which would allow her to put on the palm.

Camera Lytro really get a little (its length is slightly greater than 11 cm) and more like a toy kaleidoscope. The device weighs about 230 g is equipped with a lens with an 8-fold increase with a fixed aperture f / 2, which lets in maximum light in the entire zoom range and a proprietary sensor directly, containing thousands of built-in micro-lens options and lets you record 11 million rays of light.

device has only two buttons to power up and shoot. To change the focal length of the slider is provided. The back side is a 1.46-inch color LCD screen for selecting the focus point, viewing and framing.

currently transfer pictures taken on camera Lytro, available only on computers Mac - using a special software Lytro Desktop, which is included in the package. The Windows version is in development, release it in 2012.

With Lytro Desktop image can be processed and spread on the Internet - on Facebook or Twitter. To view the "live" images on the Internet using your own player Lytro. Snapshots can also be exported in JPEG, but then they have to choose in advance the focus.

cost of the camera is $ 399 for a model with 8 GB of internal memory, enough to store 350 photos (one photo takes about 22 MB, which is comparable to some modern SLRs) and $ 499 for a model with 16 GB of memory (750 photos) .

the camera is scheduled to begin in early 2012 and so far only in the United States.
