In holographic stereograms, speckles are generated in the reconstructed images, because random phase distributions are added to the parallax images to remove areas where images cannot be seen in the viewing area. Moreover, the reconstructed images are out of focus, because the reconstructed images that observed in the viewpoints are not 3D images but parallax images of 3D objects. In this study, we propose techniques that resolve these problems. For the speckle problem, virtual viewpoints are inserted between the original viewpoints and the phase of the parallax images displayed to the all viewpoints are modulated properly. As a result, speckles are regularized and miniaturized. For the blur problem, we calculate the diffraction calculation using the depth images adding the parallax images. As a result, the blur in the reconstructed images is suppressed. |
