Abstract
An observer-adaptive autostereoscopic display system (100) comprises a display device (102) having a screen for displaying an image and a shutter (204) being electronically controlled to have transparent (230) and non transparent segments (228, 232, 234) which alternate time-sequentially in synchronism with the display device (102). The shutter (204) is designed to block light that is traveling in arbitrary directions but to let pass light which goes from the display device to predetermined positions and which is bent by lenses (208-226) of a first (202) and a second grid (206) of lenses. The lenses (208-226) are disposed in the first (202) and the second grid (206) at a predetermined pitch distance which is substantially equal to a pixel width of the image.
