我们开发了适合小批量生产的整体摄影（IP）系统，原则上适用于动画。IP是一种理想的3D显示方法，因为用户可以从任意方向看到立体3D图像。然而，IP不如仅使用水平视差的透镜状显示器流行，这可能是因为设计和生产蝇眼透镜的初始成本非常高。我们使用了两种技术来解决这个问题。首先，我们使用两个相互垂直的透镜片代替蝇眼透镜片。双凸透镜片比蝇眼透镜便宜得多，因为它更容易生产。其次，我们使用了分数视图方法，其中透镜间距与像素间距的比率不限于简单的整数比率，这意味着不需要定制的柱状透镜。然而，原始的分数视图方法仅适用于水平视差。我们通过使用两个相互垂直的透镜片，使其适用于水平和垂直双折射。此外，我们还开发了一种简单的技术，用于为IP生成专用的合成图像。
We developed an integral photography (IP) system that is suitable for small-lot production and is, in principle, applicable to animation. IP is an ideal 3D display method because users can see stereoscopic 3D images from arbitrary directions. However, IP is less popular than lenticular display using only the horizontal parallax, probably because the initial cost of designing and producing a fly's eye lens is very high. We used two technologies to solve this problem. First, we used two mutually perpendicular lenticular sheets instead of a fly's eye lens sheet. A lenticular sheet is much less expensive than a fly's eye lens because it is easier to produce. Second, we used the fractional view method, in which the ratio of lens pitch to pixel pitch is not limited to simple integer ratios, which means that no custom-made lenticular lens is necessary. However, the original fractional view method is applicable only to horizontal parallax. We made it applicable to both horizontal and vertical parallaxes by using two mutually perpendicular lenticular sheets. In addition, we developed a simple technique for generating dedicated synthesized images for IP.
