Outline of Final Research Achievements

A full HD autostereoscopic display based on time-division multiplexing directional backlight is developed and its utility for liver surgery simulation is evaluated and confirmed. A full HD autostereoscopic display based on time-division multiplexing parallax barrier is developed. Subpixel control of the barrier is proposed and improvement of image quality is confirmed by subjective experiments. A theory to calculate the viewing zone is established and its validity is confirmed by cross-talk measurement of a prototype system. As for an autostereoscopic display using a layered panels, a method to decrease the effect of image gap between the panels due to the delay of face-tracking is proposed and its effect is confirmed by experiments using a prototype hardware.
