Abstract
We propose an integral 3D display system that enhances the viewing zone and depth range of reconstructed 3D images using eye-tracking technology and a lens array with a long focal length. To reduce crosstalk due to flipped images caused by the movement of the viewer, a lens arrangement that forms a horizontally widened optical viewing zone by rotating the lens array is designed. Unlike the conventional design, the viewing angle expanded 2.9 times to 81.4° horizontally and 1.7 times to 47.6° vertically, and the depth range doubled. Results of the evaluation experiment confirmed that crosstalk was sufficiently suppressed.
