The company introduced the Lytro Light-field camera of the second generation Bashny.Net

The company Lytro, founded by a native of Stanford University Ren Ng (Ren Ng), is engaged in the commercialization of plenoptic pictures, or pictures of the light field, the matrix system using microlens captures not flat picture and full information about the light field of the subject - the focus of such images can be produced after the shooting, and the frames received this camera makes it possible to obtain a stereo image. Very detailed and great article about the principle of operation of such a chamber published habrayuzer Antelle . The first Lytro camera was more like a fun toy than a serious camera, and the picture quality is not too high - when rendering the usual flat image resolution is only about megapixels.

The camera of the second generation, called Lytro Illym , is much more like a real camera, both in appearance and in characteristics. The diagonal of the sensor is increased from 1/3 & quot; 1 & quot ;, picture resolution is 40 megaluchey (measured in these units permit Light-field camera) against 11 in the first Lytro. Flat prints from pictures Lytro Illym can now have a resolution of about 4 megapixels, and proportionally increased focusing accuracy. Most of the camera takes a zoom lens with an equivalent focal length of 30-250 mm and a constant aperture of F2. The camera has a rotating 4-inch viewfinder resolution of 800x480 pixels. Its price - $ 1600. First deliveries are expected in July.

The camera weighs just mensche kilograms and has dimensions 86x145x166 mm. The minimum shutter speed - 1/4000 second, there is the possibility of macro photography. Lens 13 is composed of optical elements. According CEO Lytro Jason Rosenthal, unique plenoptic camera sensor not only allows you to focus after shooting footage and get three-dimensional image, but also makes it easier to correct the aberrations of the lens using the integrated software.

Theoretically, the light field cameras can have serious advantages over conventional. Besides the already mentioned post-focus and stereo images, they can run much faster than normal, since they do not need to spend time focusing. Also the possibility of refocusing reduces problems with low depth of field at maximum aperture, which may be advantageous in low light. Generally, the creators of the camera Lytro believe that plenoptic cameras can potentially make the same revolution that made digital.
