In recent year, the Head-up display is studied actively. Among them, 3D HUD attracts rising attention. In HUD application, it is assumed that stereoscopic image is displayed at far distance. Super Multi-View display provides a smooth parallax. Even if 3D image is at far distance, it be able to display 3D image which has appropriate depth. In previous studies, high resolution required for SMV. However, there are restrictions to increase the resolution. Therefore, we propose a novel SMV display using time division multiplexing and eye tracking techniques. Our new system is not required high resolution display. The proposed display consists of DMD and light source array. The ray from the light source array is reflected at DMD, and form an image at the vicinity of the pupil. The position forming an image depends on light source position. The image which is display on the DMD is changed corresponding to the focal point. To confirm the principle of the proposed method, we experiment about creating a viewing zone only in the vicinity of the pupil. From the result, we confirmed 8 viewpoints in the horizontal direction at 18.8 mm viewing zone.
