Time-sequential super multiview theater system

Recently, three-dimensional (3D) display technologies actively have been researched for improving the quality of 3D display and for reducing 3D sickness such as the vergence-accommodation conflict. One of approaches is super multiview (SMV) display in which more than two views enter the pupil of the eye. We invented a time-sequential SMV theater system which is able to change the number of views entering the pupil. The SMV display consists of the projection part and the observation part. The projection part contains a light engine to realize full-color images by using three digital micro-mirror devices (DMDs). The image projected at the screen is observed through the observation part. The optical system functions as defining the direction of the optical rays acquired by the eyes according to the position of the opening. We implement this opening by using a DMD and the movement of the opening is realized by changing the slit patterns on the DMD. Two DMDs are synchronized to each other and the projection image is selectively observed by the predetermined position of the opening sequentially. In our system, the observation part is designed the observer to wear the device and this system is expected to have a potential to provide SMV to the audience in the theater.
