Patent ID: 8172399

Claim:
A method comprising the steps of: receiving image data comprising a plurality of image streams, each of the image streams containing a plurality of frames; projecting the image data toward a viewable screen, wherein the projecting step comprises using a light source to project the image data and alternating projecting frames from both image streams; and filtering for one eye of a viewer the frames from the first one of the image streams through a filter at a second preselected polarization angle; filtering for the other eye of the viewer the frames from the second one of the image streams through a filter at a first preselected polarization angle; wherein the steps of filtering frames from the first one of the image streams and filtering frames from the second one of the image streams comprise rotating a pair of filter wheels each having a portion polarized at a preselected polarization angle and synchronized with the alternate projection of the image streams which alternately positions a portion of the first filter wheel having the first preselected polarization angle in the path of the projected image data from the first one of the image streams and a portion of the second filter wheel having the second preselected polarization angle in the path of the projected image data from the second one of the image streams.
