提出了提高粗积分体积显示图像质量的新技术。传统的体积显示器可以实现自然的三维视觉，不存在双目收敛和焦距调节的冲突，但不能表达物体的遮挡或光泽。多视图显示可以表达后者，而不能实现前者。粗积分体显示既能实现自然的三维视觉，又能同时实现遮挡和光泽的表达。由于在粗积分体积显示中形成了显示面板的实像或虚像，图像的像差会变得严重。虽然作者提出了一种光学设置来消除主要的像差，但需要进一步改进以获得更好的图像质量。本文提出了一种针对畸变图像平面的DFD方法，可以实现各分量图像之间的自然连接。该方法考虑了真实/虚拟图像平面的畸变，并将每个三维像素绘制在相邻的两个畸变图像平面上，从而使亮度与到每个平面的距离成反比。并讨论了如何选择合适的分量镜头来提高图像的连通性。
This paper proposes new techniques to improve image quality of the coarse integral volumetric display. Conventional volumetric displays can achieve natural 3D vision without conflict between binocular convergence and focal accommodation, while they cannot express occlusion or gloss of the objects. Multiview displays can express the latter while it cannot achieve the former. The coarse integral volumetric display can realize both natural 3D vision and expression of occlusion and gloss at the same time. Since real image or virtual image of the display panels are formed in the coarse integral volumetric display, aberration of the image can become severe. Though the author has proposed an optical setup to remove major aberration, further improvement is required to achieve better image quality. In this paper the author proposes DFD for distorted image plane, which can realize natural connections between component images. The proposed method takes into account the distortion of real/virtual image plane and each 3D pixel is drawn on the adjacent two distorted image planes so that the brightness may be in inverse proportion to the distance to each plane. Also the author discusses proper selection of component lens to improve connectivity of image.
