Accommodation response of super-multiview display device, which is implemented to provide horizontal-only parallax, has been investigated. Because of astigmatic characteristic of such display, the focal points of horizontal and vertical directions differ in longitudinal direction. Assuming that the accommodation response to the astigmatic image follows the distance where the average of bandwidths in vertical and horizontal direction becomes the maximum, numerical calculations presented that the accommodation restrictedly follows three-dimensional point near the display panel. To verify the consequence obtained by numerical calculations, experiments has been performed using keratometer to measure the accommodation under the situation similar to horizontal-only super-multiview display. The images focused by a cylindrical lens have been provided as stimuli to avoid argues related to the resolution of pixel pitch of display panel. The measured results show that the accommodation response restrictedly follows astigmatic image as expected by numerical calculations, however the quantitative investigation is still needed.

Computational reacquisition for real 3D object in integral imaging is proposed. The pseudoscopic problem and matching of lens array in pickup and display are fundamental problems for real-time broadcasting based on integral imaging. We propose the reconstruction method of real 3D object and computational reacquisition method without matching of pickup and display lens array. In reconstruction, the real 3D object is reconstructed with volumetric information using depth extraction and triangular mesh, which can be rotated and translated in orthoscopic geometry. In reacquisition, the virtual lens array can generate the elemental image without matching of pickup lens array using OpenGL.
