Abstract:

3D image display devices have wide applications in medical and entertainment areas. Binocular stereoscopic imaging without glasses, especially spatial-multiplexed displays such as lenticular display, barrier strip display, and single-lens stereoscopic display, is one of the most powerful and popular ways for life-like presentation of our three-dimensional environments. The definition and relationship of the image contrast and viewer crosstalk are reviewed and clarified. They are measured and compared on three different types of 3D display systems, including shutter-glasses stereoscopic display, image splitter autostereoscopic display and dual-panel autostereoscopic display. From the contrast point of view, high-quality three-dimensional perception results from a combination of high image contrast and low crosstalk. Same as a conventional two-dimensional display, high image contrast is also required for a 3D display to present a satisfactory image to either eye of the viewer. Yet, there is an extra requirement for a 3D display. The viewer crosstalk must be low enough for the viewers one eye to neglect the ghost image from the neighboring viewing zone of the other eye. The interesting fact is that there are conflicts between these two factors to generate satisfactory 3D effects. As a characteristic of the display system, the system crosstalk will confine a content provider within a certain range of image contrast to present satisfactory 3D pictures or videos to the viewer.
