Abstract
In general, multi-view autostereoscopic displays can only provide autostereoscopic images with little crosstalk at the optimum viewing distance (OVD) in the depth direction, limiting the mobility of viewers. Therefore, this paper proposes a method of increasing viewer mobility in the depth direction by varying the distance separating the parallax barrier and the display. Computer simulations and experiments were conducted to verify changes in the OVD resulting from the application of the proposed method. The results showed that the proposed method is effective at changing the OVD with respect to changes in the viewing distance. Therefore this method minimizes changes in the 3D image quality due to the viewer's depth location.
