“…However, real scene acquisition is preferable, because it does not need the timeconsuming modeling process [10], [11]. As the most direct and simplest way of real scene acquisition, lens-based pickup scheme can be used to capture real scene directly with a lens array and a single recording medium, various approaches are proposed to improve the quality of EIA [3], [4], [11], [12], but a trade-off relationship exists between the display resolution and the number of EIs for a given sensor device. Using a camera or sensor array can solve the problem effectively, and each camera or sensor records an EI of the object from a different location.…”

Limited available methods for the generation of an elemental image array (EIA) may be the most severe bottleneck for the promotion and application of integral imaging. To obtain rich information of three dimensional (3D) real scene at a relatively low cost, and solve the pseudoscopic problem in real display mode, we propose an EIA generation method based on convergent camera array through establishing the optical mapping model between the proposed method and the classical computer virtual generation method. We expound the basic principle of solving the pseudoscopic problem by changing the relative position of object and center of the convergent camera array in this paper. The experimental results indicate that the generated EIA can be displayed without the pseudoscopic problem in real display mode, relative position relationships of the objects in 3D real scene can also be accurately restored. Both preliminary optical experiments and the optical analysis are conducted to prove the feasibility and validity of the proposed method.

“…To optimize these system parameters, integral imaging analysis has been reported in Refs. [21][22][23][24][25][26][27][28][29][30][31][32]. However, in previous research, there have still been trade-offs between lateral resolution and the DoF.…”

In this paper, we propose a new 3D passive image sensing and visualization technique to improve lateral resolution and depth of field (DoF) of integral imaging simultaneously. There is a resolution trade-off between lateral resolution and DoF in integral imaging. To overcome this issue, a large aperture and a small aperture can be used to record the elemental images to reduce the diffraction effect and extend the DoF, respectively. Therefore, in this paper, we utilize these two pickup concepts with a non-uniform camera array. To show the feasibility of our proposed method, we implement an optical experiment. For comparison in details, we calculate the peak signal-to-noise ratio (PSNR) as the performance metric.

“…To solve these problems, some computations have to be made, to convert the EIs into the so-called microimages. The conversion is made by means of a simple transposition, that is, through a pixel resampling [ 5 ].…”

In this paper, we propose a new method for the generation of microimages, which processes real 3D scenes captured with any method that permits the extraction of its depth information. The depth map of the scene, together with its color information, is used to create a point cloud. A set of elemental images of this point cloud is captured synthetically and from it the microimages are computed. The main feature of this method is that the reference plane of displayed images can be set at will, while the empty pixels are avoided. Another advantage of the method is that the center point of displayed images and also their scale and field of view can be set. To show the final results, a 3D InI display prototype is implemented through a tablet and a microlens array. We demonstrate that this new technique overcomes the drawbacks of previous similar ones and provides more flexibility setting the characteristics of the final image.
