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. This contrasts with conventional cameras, which record only light intensity at various ...

2023年1月12日 · A light field camera is a digital camera designed to capture more detailed and accurate information about the light in a scene than traditional cameras. Instead of just recording the intensity and color of light at different points on a 2D image sensor, light field cameras also capture information about the direction from which the light is ...

2014年4月22日 · Manufacturer description: The Lytro Illum captures information about the angle from which light has arrived, allowing it to calculate images with different perspective and focus. Lytro calls the images 'living pictures', which are presented in a proprietary interactive format. The biggest change compared to previous Lytro cameras is the use of a much larger sensor: now a 1" type, rather than 1 ...

2020年4月10日 · Lytro was able to create a portable camera that by using light field photography, and computational photography, made possible to take one photo and then set the focal plane afterward. ... Until April 2017 he led the EIT Digital Italian Node and then was head of the Industrial Doctoral School of EIT Digital up to September 2018. Previously, up ...

We joined a micro-lens array to a digital image sensor to capture the color, intensity, and direction of light entering the camera — 11 million light rays to be precise. Light field engine. This is where the magic happens. The Light Field Engine processes the light rays captured by the sensor, so you can view it on the screen and refocus with ...

2012年2月29日 · There was a lot of excitement when the New York Times wrote about a small company promising to make focus errors a thing of the past. A camera that allowed you to focus after you take the picture. Its subject was Lytro, a startup promising to make its technology available in a consumer product on the market within a year. And, sure enough, here is the Lytro Light Field Camera.

2014年4月22日 · Lytro has unveiled the Illum light field camera, its first new hardware since the original Lytro launched more than two years ago. Like its predecessor, the Illum captures information about the angle from which light has arrived, allowing it to calculate images with different perspective and focus. The biggest change is the use of a much larger sensor: now a 1" type, rather than 1/3" type ...

2023年2月7日 · Are Light Field Cameras the Future of Photography? In 2012, the first consumer market light field camera was released by the company Lytro. This camera had a one-megapixel resolution with a constant aperture of f/2 and sold for between $400 and $500. Since then, very few consumer-targeted light field cameras have hit the market.
