Wide-Viewing-Angle Integral Imaging System with Full-Effective-Pixels Elemental Image Array [PDF]
Micromachines, 2023 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-
