  1. Digital & HD TV Pioneer and Poet of the Known Un- Owneds, Donald Rumsfeld Known Un-Owneds:What We Know We Don’t Yet Have Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  2. Movies & TV Stimulate Sight and Hearing And? Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  3. Five Senses? discrimination “cocktail-party effect” • Hearing (audio) • loudness, pitch, duration, direction, depth, vector, rhythm, harmony, + • Sight (video) • brightness, color, shape, depth, transparency, vector, number, + • Feeling (Tingler & motion seats) • pressure, texture, moisture, fatigue, heat, thirst, hunger, nausea, pain, + • Smell & Taste (Odorama, CP 5+1) Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  4. Vision – We Already Have HD 1953 3-D TV glasses • Add 3-D • 3-D TV transmissions in 1928 • Increase color gamut • Increase dynamic resolution • Whyincreasetemporalorspatialresolution? • Post-production options • re-frame, stabilize, scan BG, slo-mo • Perception evolves Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  5. Perception is Learned Kittens deprived from birth of a particular type stimulus cannot perceive that type stimulus until it is learned Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  6. Human Perceptions Evolve 1895 L’arrivée d’un train en gare de La Ciotat 1919 Edison “Tone Test” Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  7. Human Perceptions Evolve “One of my neighbors was so much captivated that she sprung to her feet... and waited until the car disappeared before she sat down again” – Henri de Parville, 1895 1895 L’arrivée d’un train en gare de La Ciotat Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  8. Human Perceptions Evolve "It did not seem difficult to determine in the dark when the singer sang and when she did not. The writer himself was pretty sure about it until the lights were turned on again and it was discovered that [the singer] was not on the stage at all and that the new Edison alone had been heard.“ Pittsburgh Post 1919 Edison “Tone Test” Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  9. Human Resolution Theory - 1862 Snellen Chart 20/20 (6/6) optotype Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  10. Resolution and Viewing Distance • 1 arc minute = 30 cycles per degree (cpd) • NTSC ≈ 480 active lines = 8° • 8° = 7.15 x the picture height (PH) • Similarly, 1080 lines = 18° = 3.16 x PH • 4K ≈ 36° = 1.54 x PH • UDTV: 4320 lines = 72° = 0.69 x PH • for 9’ viewing distance, screen height = 13’ Lechner Distance 9 feet Mark Schubin, HPA “Visions of the Future,” 2009 February 17 courtesy Warner Bros. Technical Operations

  11. Problems with 30-cpd Theory higher-frequency content • 3 chartlinesbelow20/20 • April SMPTE Motion ImagingJournal: NHK “Research on Human Factors in UHDTV” • possible to distinguish between 78 and 156 cpd • 156 cpd is more than five times the 20/20 criterion • “realness” is a function of image detail • rises rapidly to 50 cpd • continues rising through 156 cpd • Bottom line: more rez works Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  12. But Lenses Have Issues 2/3-inch 1080-line HD = 100 lp/mm S35 “4K” ≈ 60 lp/mm 2/3-inch 4320-line UD = 400 lp/mm 1/6-inch 1080-line HD = 379 lp/mm (simplified from Small Format HD Acquisition, Larry Thorpe, Canon, 2005 SMPTE Fall Technical Conference) 100 2/3-Inch HD MTF % 20 40 60 80 100 LP/mm Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  13. Fixing Optical Issues w/o Optics Canon HJ17Ex7.7B, 36 glass elements lateral chromatic aberration correction via LUT Astigmatism, coma, geometric, Petzval, & spherical aberrations, flare, ghosts, vignetting, light distribution, MTF, and diffraction? Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  14. Deconvolution from The Scientist and Engineer’s Guide to Digital Signal Processing, by Steven W. Smith, Ph. D., California Technical Publishing Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  15. Convolutions • Multiple audio sources • Echoes • Room tone • Lens focus • Camera shaking • Excess fog known blind Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  16. Holographic lenses Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  17. 500-watt halogen light Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  18. Imaging Dynamic Range courtesy of Thomson 10,000,000:1 (>23-stop) contrast ratio Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  19. More Basic Known Un-Owneds • Color gamut • Why not all colors? • Displays • Direct stimulation of the visual cortex • Eye projection • Eye-tracking for data reduction • Personal vs. community • Sound imaging • height Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  20. High-Frame-Rate Viewing popped water balloon Vision Research Phantom V12 shoots 720p to ~7000 fps not HDTV cameras from AOS, CPL, DRS, Fastec, i-Movix, Kinor, NAC, Photo-Sonics, Photron, PCO, Redlake, Shimadzu, SVSi, VR, Weinberger, Weisscam simulation area for human- vision training? Field Emission Technologies 240-fps display Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  21. Temporal & Dynamic Resolution Do we know the human visual limit of temporal resolution? Regardless, we know that eye tracking makes moving objects static Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  22. “True” 3-D RabbitHoles Media in Demo Room James Clar 10x10x10 voxel monochrome Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  23. Interactivity • Are we storytelling or storymaking? • Choices rapidly grow: 220=1,048,576 Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  24. Artists Advance Technology • Satellite Arts Project, 1975: GEO latency • World Opera Project, 2009: fiber latency • Real time contrast compression, 1973 • Multilingual live HD subtitling, 2007 • Beyond-color imaging Military, too Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  25. Sometimes Both Together Mark Schubin, HPA “Visions of the Future,” 2009 February 17

  26. Behind the Scenes • The storage bit bucket • buckets don’t care about format • The universal IP address & ubiquitous wireless • Voice recognition • Thought control? Mark Schubin, HPA “Visions of the Future,” 2009 February 17
