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.

This paper proposed a 3D source generation method for generating elemental image array (EIA) of integrated imaging. The proposed method can break through the constraints between parameters of traditional integrated imaging record device and display device, and allow to obtain a new set of EIA suited to be displayed by an integrated imaging display device with arbitrary parameters from any given recorded EIA. Threedimensional display results demonstrate the correctness and effectiveness of the proposed method.

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.
