In this paper, a novel measurement method of multi-view 3D display for determining an optimum viewing distance (OVD) is proposed. Using this method, the OVD can be efficiently determined by analyzing ray tracing results from at least one view–point images of some local areas of a multi-view 3D display and position error of each view-point images formed from entire 3D display area can be also calculated depending on z-direction.
A new method is introduced to reduce three crosstalk problems and the brightness variation in 3D image by means
of the dynamic fusion of viewing zones (DFVZ) using weighting factor. The new method effectively generates the
flat viewing zone at the center of viewing zone. The new type autostereoscopic 3D display can give less brightness
variation of 3D image when observer moves.
An autostereoscopic 3D display provides the binocular perception without eye glasses, but induces the low 3D effect and
dizziness due to the crosstalk effect. The crosstalk related problems give the deterioration of 3D effect, clearness, and
reality of 3D image. A novel method of reducing the crosstalk is designed and tested; the method is based on the fusion
of viewing zones and the real time eye position. It is shown experimentally that the crosstalk is effectively reduced at any
position around the optimal viewing distance.
Generally, autostereoscopy has some shortcomings as a fusible stereo condition. Since viewer is keep a viewing distance
viewer and autostereoscopic display. The previous measurement method to measure the characteristics of the autostereoscopic
display has a problem. We proposed a moving image sensor method for measuring auto-stereoscopic
display. By using this method, the intensity distribution can be measured using the correct optimum view distance
(OVD). In addition, OVD around the crosstalk can be found.
