  2. One Heck of a Home TV 2006 August 16, Stan Glasgow, pres. Sony Electronics, “next big leap” in HD [beyond 1080-line] could be 3-5 years 4096x2160 30-cpd (1862) 20/20 (6/6) vision matches 1080-line rez at ~ 70-inch @ 9’ 70-inch:1080-line:: 140-inch:2160-line Panasonic 150-inch/3.8-m plasma TV at 2008 Consumer Electronics Show Mark Schubin, HPA Technology Retreat, 2012 February 15

  4. Problems with 30-cpd Theory • Edges • 3 chartlinesbelow20/20 • April 2008 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 Mark Schubin, HPA Technology Retreat, 2012 February 15

  5. Beyond-HDTV Spatial Resolution • Other gear: • codecs, recorders, up- & down-convert, productionswitchers • Cameras from: • ARRI, Astro, Canon, Dalsa, Hitachi, Ikegami,JVC, Lockheed-Martin, Meduza, NHK, Olympus, Red, Sony, Vision Research • Displays from: • CMO, JVC, LG, Panasonic, Samsung, Sharp, Sony, Toshiba Mark Schubin, HPA Technology Retreat, 2012 February 15

  6. Beyond HD Advantages Skewed HD • More detail • Reframing/stabilization • Single-sensor 3D • Increased sharpness Resulting HD Desired HD 4k Zepar S3D lens on VR Phantom 65 Mark Schubin, HPA Technology Retreat, 2012 February 15

  7. Real MTF Curves EOS 10D 3072 x 2048 EOS 20D 3504 x 2336 14% linear increase in sensors courtesy Bob Atkins www.bobatkins.com used with permission Mark Schubin, HPA Technology Retreat, 2012 February 15

  8. Real-World Sharpness Change EOS 10D 3072 x 2048 EOS 20D 3504 x 2336 courtesy Bob Atkins www.bobatkins.com used with permission • Also Disadvantages • lens qual., sens., dyn. range • compensate with larger sensor • or lower resolution • data-rate rises by square of linear rez rise • compressed increase should be much less Mark Schubin, HPA Technology Retreat, 2012 February 15
