Stereoscopic television system

Claim 2

A stereoscopic television system having first and second openings through which light rays reflected from an object to be viewed enter, said system comprising: a first polarizer polarizing light rays passing through said first opening; a second polarizer polarizing lightly rays passing through said second opening, polarization planes of said first and second polarizers being different from each other; an optical means for aligning center axes of said light rays passing through said first and second openings to generate aligned light rays; a polarizer switch receiving said aligned light rays and selectively and alternately passing light rays polarized by one of said first and second polarizers; a zoom lens optically treating said aligned light rays for zoom operation; a video camera converting optical images of light rays passing through said polarizer switch and said zoom lens into electrical signals corresponding to said light rays passing through said first and second openings; and a television system displaying an image of said object based on said electrical signals.

Claim 3

A system as claimed in claim 1, further comprising: a controller controlling said polarizer switch and said television system such that scanning fields corresponding to light rays passing through said first and second openings are alternately generated in scanning fields of said television system; and a third polarizer, provided in front of a display of said television system, polarizing light rays emitted from scanning fields corresponding to light rays passing through said first and second openings in different polarization plates.

Claim 4

A stereoscopic television system having first and second openings through which light rays reflected from an object to be viewed enter, said system comprising: a first polarizer polarizing light rays passing through said first opening; a second polarizer polarizing light rays passing through said second opening, polarization planes of said first and second polarizers being different from each other; an optical means for aligning center axes of light rays passing through said first and second openings to generate aligned light rays; a polarizer switch receiving said aligned light rays and selectively and alternately passing light rays polarized by one of said first and second polarizers; a zoom lens optically treating said aligned light rays for zoom operation; a polarizing beam splitter separating light rays passing through said first and second openings after passage through said polarizer switch and said zoom lens; a first video camera converting optical images of separated light rays corresponding to said light rays passing through said first opening into electrical signals; a second video camera converting optical images of separated light rays corresponding to said light rays passing through said second opening into electrical signals; and a television system displaying an image of said object based on said electrical signals.

Claim 5

A stereoscopic television system having first and second openings through which light rays reflected from an object to be viewed enter, said system comprising: a first polarizer polarizing light rays passing through said first opening; a second polarizer polarizing light rays passing through said second opening, polarization planes of said first and second polarizers being different from each other; an optical means for aligning center axes of light rays passing through said first and second openings to generate aligned light rays; a polarizer switch receiving said aligned light rays and selectively and alternately passing light rays polarized by one of said first and second polarizers; a zoom lens optically treating said aligned light rays for zoom operation; a polarizing beam splitter separating light rays passing through said first and second openings after passage through said polarizer switch and said zoom lens; a first video camera converting optical images of separated light rays corresponding to said light rays passing through said first opening into electrical signals; a second video camera converting optical images of separated light rays corresponding to said light rays passing through said second opening into electrical signals; and a television system displaying an image of said object based on said electrical signals.
