Abstract:
1. A polarized stereoscopic display device for displaying stereoscopically a first image and a second image of an object photographed at different angles, the device comprising: a first signal processor configured to signal process the first image and produce a first processed image; a second signal processor configured to signal process the second image and produce a second processed image; a first projector configured to receive and project the first processed image on a screen; and a second projector configured to receive and project the second processed image on the screen, wherein the output images of the first and second projectors have a 90 degree phase difference from each other, wherein one of the first signal processor and the first projector comprises: an image rotating portion configured to rotate the first image by 90 degrees; and an adjusting portion configured to adjust at least one of the horizontal and vertical distances of the rotated image to fit in the size of the screen and output it to the first projector, wherein the first projector is rotated 90 degrees about a projection axis thereof with respect to the second projector so that the output images of the first and second projectors have a 90 degree phase difference from each other, wherein the first and second projectors do not require a polarization element, and wherein the first and second projectors are substantially parallel with respect to the projection axis.
