Lytro Illum 2nd generation light field camera Front and back of a Lytro, the first consumer light field camera, showing the front lens and LCD touchscreen. 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 ...
In June 2011, Apple Inc CEO Steve Jobs purportedly met with Ng to discuss improvements for the iPhone camera. [18] Although not a true light field camera, the HTC One (M8) mobile phone released in April 2014 mimics Lytro's depth-sensing functionality through the use of a second camera and stereoscopic post processing.

Examples of computational photography include in-camera computation of digital panoramas, [6] high-dynamic-range images, and light field cameras. Light field cameras use novel optical elements to capture three dimensional scene information which can then be used to produce 3D images, enhanced depth-of-field, and selective de-focusing (or "post ...
FujiFilm launches world's first digital 3D camera with 3D printing capabilities. [26] 2011 – Lytro releases the first pocket-sized consumer light-field camera, capable of refocusing images after they are taken. 2018 – Kodak resumes the production of Ektachrome film.
Light field microscopy (LFM) is a scanning-free 3-dimensional (3D) microscopic imaging method based on the theory of light field.This technique allows sub-second (~10 Hz) large volumetric imaging ([~0.1 to 1 mm] 3) with ~1 μm spatial resolution in the condition of weak scattering and semi-transparence, which has never been achieved by other methods.
Focus stacking also allows generation of images physically impossible with normal imaging equipment; images with nonplanar focus regions can be generated. Alternative techniques for generating images with increased or flexible depth of field include wavefront coding, light-field cameras and tilt.

The camera measures the intensity of light at each image point, a light field. In practice, a digital camera measures this light field at discrete points, pixels, but given that the pixels are sufficiently dense, the pixel intensities can be used to represent most characteristics of the light field that falls onto the image plane. A common ...
