What are Sega 3D glasses ?
Sega designed special glasses for it’s video game console to be able to produce 3D video games. Those glasses used LCD shutter method for producing 3D images. In this method the picture is snown to different eyes after each other. The LCD panels in front of both eyes are controlled so that one eye sees one screen image and the other eye sees the second image etc. With normal TV it was possible to show 25 or 30 images per second (depending on TV standard used) to both eyes. The image flickers quite much, but gives well noticable 3D effect. 3D games for sega game consoles did not sell very well and Sega dropped those glasses from it’s product lines.
