“…For example, InIm systems based on curved lens array [ 7 , 8 , 9 ] were built to make the parallel reconstructed rays converge to the center and thus increase the public viewing zones of the lens units. Methods using multi-plate lenses [ 10 , 11 , 12 ] have also been reported; by designing and optimizing the compound lens, the individual field of view (FOV) of each lens unit was extended. Additionally, a high refractive index medium was employed between the elemental image plane and the lens array to increase the deflections of the exit rays [ 13 ].…”

There exists a defect of the narrow viewing angle in the conventional integral imaging system. One reason for this is that only partial pixels of each elemental image contribute to the viewing angle and the others cause image flips. In this paper, a wide-viewing-angle integral imaging system with a full-effective-pixels elemental image array (FEP-EIA) was proposed. The correspondence between viewpoints and pixel coordinates within the elemental image array was built up, and effective pixel blocks and pixels leading to flipping images were deduced. Then, a pixel replacement method was proposed to generate the FEP-EIAs, which adapt to different viewing distances. As a result, the viewing angle of the proposed integral imaging system was effectively extended through the replacement of the pixels, which caused the image flips. Experiment results demonstrated that wide viewing angles are available for the proposed integral imaging system regardless of the viewing distances.

“…Researches on improving the viewing angles have made some progresses. For example, schemes based on the optimization of the core imaging elements, the lens arrays, were reported [7][8][9][10][11][12][13], by changing the directions of the light rays emitted from the lens arrays, the viewing angles were expanded. Also, InIm systems based on time division and space division multiplexing techniques were presented which could increase the viewing angles in multiples [14][15][16].…”

A simple but effective method for increasing the viewing angle of the integral imaging system was proposed. Unlike the existing methods, the viewing angle was extended through the fully effective utilization of the pixels within the elemental image array rather than the modifications to the system structures or the importing of extra devices. The relationships between the pixel positions and the viewing zone distributions were analyzed, the algorithm model for replacing the invalid pixels was built and then a method for generating full‐effective‐pixel elemental image array (FEP‐EIA) was proposed. Experiment results demonstrated that the viewing angle of the integral imaging system was significantly increased with the proposed method.
