Method and apparatus for projecting 2d and 3d motion pictures at high frame rates

Abstract

High-frame-rate stereoscopic projection using a single digital projector provides a powerful sense of immersion when shown on wide screens, and the human eye perceives each frame as unique and separate from the others by virtue of the natural left-right “shuttering” that occurs via the chosen 3D projection technology. Techniques are provided for the introduction of one or more consecutive “digital dark frames” into the image streams presented to the dual projectors in such a manner that the sequence of out-of-phase photography is replicated via out-of-phase projection. This is achieved by alternately introducing the dark frames so that the sequence of stereoscopic images is presented in proper temporal continuity.
