Integral Imaging
Summary
Integral imaging, also called integral photography, offers a true 3D image. In integral imaging the perception of depth is limited by out-of-focus images originating from a narrow depth of field area, by a narrow viewing angle given by the f-number of the lenses, defined as the focal length divided by the diameter of the aperture, and by limited resolution. The resolution of a small area of an elemental image is supposed to represent the better part of the entire object, which requires a large and not-easy-to-realize pixel density. This chapter presents remedies for an improvement of these challenges. Integral videography (IV) is an extension of integral imaging allowing video and interactive content to be viewed by several observers. The chapter investigates a 2D/3D approach in which a polymer-dispersed liquid crystal display (PDLC) is switched off for a 2Ddisplay and switched on for a 3Dpresentation.
