“…With the micro-lens pitch p = 1.27mm and pixel size r = 0.137mm, the optimal moiré-reduced angles can be obtained by Eqs. In our experiments, the unified EIA is generated by our previous method [7] and the non-unified EIA is generated by the proposed method. Table 2 shows the characteristics of the different method.…”

“…In the conventional II display, the pitch of the periodic microlens may be not integer multiple of liquid crystal display (LCD) pixel size, so the micro-lens needs a certain rotation [7,8]. In that case, the micro-lens is tilted and micro-lens edge intersects some LCD pixels.…”

“…However, this method ignores the different pixel arrangements for different positions in the tilted EIA. Another way to obtain the EIA is transforming the conventional EIA into the tilted EIA according to optimal tilted angle, as we proposed previously [7]. In this method, different EIs must have a uniform effective pixel arrangement.…”

In this paper, we propose a method based on selective pixel sampling algorithm to generate non-unified integral imaging (II) elemental image array (EIA) with reduced moiré patterns at a smaller rendering cost and higher three-dimensional (3D) resolution. In the proposed method, the redundant 3D information is captured for the non-unified pixel arrangement of elemental images (EI) and the moiré patterns are constrained by the constraint equations. The corresponding EIA's information is sampled from the obtained 3D information selectively. Appropriate experiments are carried out and the results show that the proposed method can increase the resolution of the reconstructed 3D images and reduce rendering cost markedly in the generation of ultra high-definition (UHD)EIA.

“…These methods present only 2D images to the observers. Integral imaging (II) display, which was first proposed by Lippmann in 1908, is regarded as a promising 3D display [6][7][8][9]. Recently, we have proposed a dual-view integral imaging (DVII) 3D display [10].…”

We propose a dual-view integral imaging (DVII) 3D display using polarizer parallax barriers (PPBs). The DVII 3D display consists of a display panel, a microlens array, and two PPBs. The elemental images (EIs) displayed on the left and right half of the display panel are captured from two different 3D scenes, respectively. The lights emitted from two kinds of EIs are modulated by the left and right half of the microlens array to present two different 3D images, respectively. A prototype of the DVII 3D display is developed, and the experimental results agree well with the theory.

“…It can provide full-parallax and continuous-viewing 3D images and does not require any special glasses or coherent light, such as those used in multi-view auto-stereoscopic 3D display or holography [2][3][4][5][6][7]. Integral imaging has attracted extensive attention for its research and application in the area of 3D sensing and display .…”

Abstract:In this paper, we analyze the depth of field (DOF) of integral imaging displays based on wave optics. With considering the diffraction effect, we analyze the intensity distribution of light with multiple microlenses and derive a DOF calculation formula for integral imaging display system. We study the variations of DOF values with different system parameters. Experimental results are provided to verify the accuracy of the theoretical analysis. The analyses and experimental results presented in this paper could be beneficial for better understanding and designing of integral imaging displays. References and links1. G.
