  13. 3D+2DTV Time L + αR [R+(1-R)] L LLL L LLL L LLL R RR R RR L LL 3D+2D Dimmer R RR R RR L LL As Seen Without Stereo Glasses

  14. 3D+2DTV Time L + αR [R+(1-R)] L LLL L LLL L LLL R RR R RR L LL 3D+2D Dimmer R RR R RR L LL As Seen Without Stereo Glasses Variable-Length R R R R L LLLL

  15. 3D+2DTV Time L + αR [R+(1-R)] Brightness of Right Stereo Image αR= Variable-Length R R R R L LLLL Brightness of Left Stereo Image

  16. Darkest and Brightest Pixel of 2D Image % Variable-Length Frames: Brightest Pixel: Variable Length Brightest Pixel = 1- αR/(1+2αR) R R R R L LLLL Brightness Dimmed, Equal-Length Frames: Brightest Pixel: Equal Length Brightest Pixel = (1+αR)maxL Darkest Pixel R RR R RR L LL % % % % % αR Darkest Pixel = αRmaxL

  17. Viable α? 2D Normal 2D Low Contrast Acceptable 2D View α=0% α=100% Acceptable 3D View 3D Brightness Too Unequal 3D Normal

  18. Viable α? OK Acceptable 2D View α=0% α=100% Acceptable 3D View

  19. TheoryExperiments2D Viewer Preferences 3D Depth Perception 3D IllusionsPrototype

  20. Viewer Preference Test: Composite 2D Image Standard 3DTV 3D+2DTV Double-Image Lower Contrast α=40%

  21. Viewer Preference Test: Composite 2D Image Standard 3DTV 3D+2DTV α=20% α=40% α=60%

  22. 2D Viewers Prefer 3D+2DTV to 3DTV Variable-Length % Who Prefer 3D+2DTV Equal Length % % % % % αR

  23. 3D Depth Perception Test Far Near Stereo Image Shown

  24. 3D Depth Perception Test Far Near Perceived 3D Image

  25. 3D Depth Perception Test Perceived 3D Image

  26. Depth Estimation Excellent for α ≥ 25% Error in Depth Estimation (degrees disparity) % % % % % αR

  27. Viable α α=40% OK! Acceptable 2D View α=100% α=0% Acceptable 3D View α=25%

  28. Adaptation to a Darker Image Stationary Object Dark Lens Left Eye Right Eye

  29. Dimmer Image = Delayed Image Stationary Object SLOW

  30. Moving Objects: Disparity = Depth Time = 1 … 2 … 3 … 4 Moving Object Apparent Location SLOW

  31. Pulfrich Effect Creates Depth Super Bowl Commercial - Diet Coke Doctor Who 3rd Rock from the Sun

  32. 3D Depth Perceptionof Moving Objects Stereo Image Shown

  33. 3D Depth Perceptionof Moving Objects Perceived 3D Image

  34. Depths of Moving Objects Distorted  Fast  Slow Depth Error (Degrees)  Slow  Fast Left Eye Dimmer Equal Brightness Right Eye Dimmer
