超级多视图显示器提供平滑的运动视差，而无需特殊眼镜，并且期望观察者免于由视差-聚散冲突引起的视觉疲劳。然而，在显示设备上需要大量的像素，因为高密度光线被要求用于良好质量的图像，并且每条光线需要对应的像素。我们已经提出了一种方法，以减少所需的像素数，限制射线发射到周围的观察者的瞳孔。该显示器基于透镜状方法。如上所述，光线应该只射到观察者的瞳孔周围。为此，使用其视域角变窄的双凸透镜，并且双凸透镜由定向光照射以抑制旁瓣。改变定向光的方向以跟随观察者的瞳孔。在本文中，我们构建了一个原型显示器，并进行了实验。实验结果证实，我们可以看到图像对应的从每个视点的摄影图像的变化。此外，它证实了旁瓣的抑制，无法看到观察区以外的图像。实验结果表明了该方法的有效性。
A super multi-view display provides smooth motion parallax without special glasses, and it is expected that the observer is free from the visual fatigue caused by the accommodation-vergence conflict. However, a huge number of pixels are required on a display device because high-density rays are required for good quality images and each ray needs corresponding pixel. We have proposed a method to reduce the required number of pixels by limiting rays emitted to only around observer’s pupils. The display is based on the lenticular method. As stated above, the rays should be shot out to only around observer’s pupils. To do this, the lenticular lens of which viewing zone angle is narrowed is used and the lenticular lens is illuminated by directional light to suppress side lobes. The direction of directional light is changed to follow the observer’s pupil. In this paper, we constructed a prototype display and conducted an experiment. The experimental result confirmed that we could see image corresponding from each viewpoint by the change of the photographing images. In addition, it confirmed suppression of the side lobes by couldn’t see the image outside the viewing zone. By these results, we showed the effectiveness of the proposed method.
