Light Field Capture
How does a light field camera capture the light rays?
Recording light fields requires an innovative, entirely new kind of sensor called a light field sensor. The light field sensor captures the color, intensity and vector direction of the rays of light. This directional information is completely lost with traditional camera sensors, which simply add up all the light rays and record them as a single amount of light.
Light Field Processing
How do light field cameras make use of the additional information?
By substituting powerful software for many of the internal parts of regular cameras, light field processing introduces new capabilities that were never before possible. Sophisticated algorithms use the full light field to unleash new ways to make and view pictures.
Relying on software rather than components can improve performance, from increased speed of picture taking to the potential for capturing better pictures in low light. It also creates new opportunities to innovate on camera lenses, controls and design.
