Abstract
Computational photography is techniques that use digital computation instead of optical processing. Computational photography can improve the capabilities of a camera, and also can introduce new features that were not possible at all with film based photography. Computational photography includes internal-camera-computation of digital panoramas, high-dynamic-range images, and light field cameras. Especially, light field cameras use novel optical elements to capture three-dimensional scene information that can then be used to produce 3D images, editing depth-of-field, and selective de-focusing. Enhanced depth-of-field reduces the need for mechanical focusing systems. All of these features use computational imaging techniques. In extreme cases of using computational cameras, captured image is senseless for human eyes without computation.
