Agenda • Requirements for Stereoscopic Viewing • Types of Stereoscopic projection • Advantages of each type • Efficiency of each type • JVC Stereoscopic Projection Systems • Credit and thanks 3AUG2005 Rod Sterling Siggraph2005 2 - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 3
Key to Stereoscopic viewing • The key to any 3-D system, is of course, "CONTENT", but the projection system should enhance the content, not add artifacts to take away from the true experience. • True 3-D effect requires high fidelity to "fool" your brain into thinking the image is three dimensional - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 4
3-D Stereoscopic Projection High Fidelity Viewing Requirements • Key requirements - Lack of projector added artifacts • Pixel structure • Video noise • Flashing due to frame rate • Black level • Brightness • Color 3AUG2005 Rod Sterling Siggraph2005 4 - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 5
3-D Stereoscopic Projection • Key requirements - Good left/right eye extinction ratio • Should be >100:1 - Optical quality screen • Front or rear, low gain, - Easy to wear glasses • Light weight • Easy to see through • Feel like not there • Large field of view 3AUG2005 Rod Sterling Siggraph2005 - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 6
Types of Stereographic Projection • Active - May be one or two projectors - Requires synchronous shutter glasses • Passive - Maybe one or two projectors - Polarization type • Circular • Linear - Anaglyphic • Simple Red/Blue • Infitec® 3AUG2005 Rod Sterling Siggraph2005 6 - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 7
Active System • One projector approach - Requires 2x frame rates >120Hz - Frame double to eyes • Active glasses each person • LC Shutter on projector • Two projector approach - Fakespace Beacon system • Duty cycle - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 8
Passive System • Polarization types - Linear - high extinction ratio, head movement dependant - Circular - lower extinction ratio, head movement invariant • Anaglyphic type - Infitec® - Highest extinction ratio, head movement invariant, screen independent 3AUG2005 Rod Sterling Siggraph2005 8 - JVC DLA-RS15U | Stereoscopic Projection using D-ILA projectors--presentation giv - Page 9
