Viewing-point detection system using specific image processing for eye-position tracking autostereoscopic display

We have developed a viewing point detection system using specific image processing for an eye-position tracking autostereoscopic display. The system consists of a CCD camera with a coaxial IR light illuminator and an image processing unit. The image processing unit executes two specific processes. The first process enhances viewer's pupils form his/her image to obtain stable viewer pupil extraction. The second process predicts the viewing point in the even the viewer blinks. In applying the system to an eye-position tracking autostereoscopic display, it was confirmed that the system offers stable and continuous tracking performance.© (1999) COPYRIGHT SPIE--The International Society for Optical Engineering.
