Abstract
We have been developing a Super Multi-View 3-D display system that enables natural 3-D vision using super multi-perspective images with fine perspective-pitch, which is narrower than the half of pupil diameter of viewer's eyes. We call the display system Fan-like Array of Projection Optics (in short FAPO system). The length of the first version of FAPO system was too long. So, down sizing of FAPO system was tried by using small LCD panels. Consequently, the length of FAPO system became about half compared with the first version. For widening the horizontal viewing zone, we have introduced an eye-position tracking system. The eye-position of the observer is precisely measured in real time by processing face image of the observer illuminated by infrared light. And, in the eye-position tracking system of the display system, the position of viewing zone is changed by rotating the concave mirror used in the display system. At the same time, the 3-D images to be displayed are also changed according to the position, using the measured eye-position data. The eye-position tracking allows observer to watch naturally 3-D images.
