Abstract
Recently, a floating display system based on integral imaging (InIm) was proposed. Though the floating display system based on InIm can provide moving picture with great feel of depth to the observer, it has limited expressible depth range because the expressible depth range of InIm is limited. In this paper, the expressible depth range of the floating display system based on InIm is analyzed based on the analysis on the expressible depth range of the InIm. Also, a depth-enhanced floating display system based on InIm is proposed. In the proposed depth-enhanced floating display system based on InIm, the lens array of the InIm is placed at the focal plane of the floating lens. Additionally, the seams on the lens array become less distinct since they are also placed at the focal plane of the floating lens. However, the size of the object changes when the object is out of the overall central depth plane. Thus, the size of objects in elemental image should be rescaled to display correct three-dimensional image.
