Multi-Perspective 3D display is expected to reconstruct a 3-Dimensional image without flipping, following on the observers’ movement. Previous works have studied ways to reduce the conspicuousness of the flipping of the reconstructed image caused by the moderate blurring. This paper gives the results of our efforts to get rid of the flipping of the reconstructed image without blurring by the subjective evaluation of several holographic stereograms comprised of different numbers of Multi-Perspective-Views. Experimental results suggest that the flipping-free reconstructed image is obtained to make the viewing zone of the each perspective image at the viewing position smaller than the pupil of the eye. This means that the flipping-free image is dependent on the continuity of the perspective images themselves, which is surely incident to the pupil of the viewer’s eye simultaneously.

In the actual space, when we accommodate an object, surroundings blur. This paper gives experimental results to elicit the blur between the images of the different depth, reconstructed by Multi-Perspective-Views, that are surely incident to the pupil of the observer’s eye simultaneously. According to the increase of the number of Multi-Perspective-Views being incident to observers’eye, observers easily control to watch the multiplex images of the standard image piling up just one. Then, the test images being detached from it become blur. This means Multi-Perspective 3D display has an ability to elicit the accommodation. Experimental results suggest that the more the subtle difference of the image depth is reconstructed, the greater the increase in the required number of Multi-Perspective-Views as a logarithm becomes.
