“…For solving the physical limitations, several researchers have proposed solutions to the pseudoscopic problem [63][64][65][66], to the uncertainty in the position and angle of the microlenses and the elemental images with respect to the sensor [67][68][69][70], and to the limitation of the viewing angle [71][72][73][74]. Solutions to the limited depth of field [75][76][77] or to the detrimental effect of the facet braiding have also been proposed [78,79].…”

Here, we present a review of the proposals and advances in the field of three-dimensional (3D) imaging acquisition and display made in the last century. The most popular techniques are based on the concept of stereoscopy. However, stereoscopy does not provide real 3D experience, and produces discomfort due to the conflict between convergence and accommodation. For this reason, we focus this paper on integral imaging, which is a technique that permits the codification of 3D information in an array of 2D images obtained from different perspectives. When this array of elemental images is placed in front of an array of microlenses, the perspectives are integrated producing 3D images with full parallax and free of the convergenceaccommodation conflict. In the paper we describe the principles of this technique, together with some new applications of integral imaging.

We report a new procedure for the capture and processing of light proceeding from 3D scenes of some cubic meters in size. Specifically we demonstrate that with the information provided by a kinect device it is possible to generate an array of microimages ready for their projection onto an integralimaging monitor. We illustrate our proposal with some imaging experiment in which the final result are 3D images displayed with full parallax.Index Terms-Integral imaging, kinect, 3D monitors. I. INTRODUCTIONonventional photography is fully adapted for recording in a 2D sensor the images of the 3D world. Although the images produced by photography are essentially 2D, they carry many cues that account for the 3D nature of the recorded scenes. This is the case, among others, of the perspective rules, which make closer objects to appear biger than further ones. This effect is due to the well-known fact that the size of the image in the photographic sensor is determined by the angular size of objects. Other cues are shadows, occlusions or defocus. In case of video recording, the relative speed of moving objects (or static objects when the camera is moving) is also a significant depth cue. For most of applications the capture and display of 2D images provides enough information and/or satisfaction to users and minimizes the amount of data to be stored, transmitted and displayed. This is the reason for the still massive use of 2D photography and video.However, the need for capturing and displaying the 3D information of 3D scenes is increasing very fast in the 21 st century. Its potential application in, for example, microscopy [1],[2], medical imaging [3]-[6], optical inspection in production chains [7], security monitoring [8], or virtual simulators for civil or military applications [9], etc., makes the capture and display of 3D images a hot topic in the research end/or engineering for the next decade.

The original aim of the integral-imaging concept, reported by Gabriel Lippmann more than a century ago, is the capture of images of 3D scenes for their projection onto an autostereoscopic display. In this paper we report a new algorithm for the efficient generation of microimages for their direct projection onto an integral-imaging monitor. Like our previous algorithm, the smart pseudoscopic-to-orthoscopic conversion (SPOC) algorithm, this algorithm produces microimages ready to produce 3D display with full parallax. However, this new algorithm is much simpler than the previous one, produces microimages free of black pixels, and permits fixing at will, between certain limits, the reference plane and the field of view of the displayed 3D scene. Proofs of concept are illustrated with 3D capture and 3D display experiments.
