EN: Lytro camera
An innovative camera introduced in 2011 that takes pictures without focusing. Selective focusing is accomplished afterwards, on a computer when your images are downloaded. The camera doesn’t measure its images in standard megapixels, but rather in mega rays – the number of light rays captured by the camera’s light-field sensor. It is promoted as a light field camera that captures light throughout the scene in front of the lens, as opposed to the cameras consumers are used to, which bring a particular thing into focus first. The result is an image that can be focused after it is taken.
