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.
