February 2016, Electronic Imaging, San Francisco—Dae-Sik Kim from Samsung described a different RGGB color architecture that improves relative resolution and reduces color fringing artifacts. Sub-pixel rendering and new LED color control filter algorithms provide the new functionality. Large-area LED panels are being widely used in indoor and outdoor displays to provide information in public areas. [...]

February 2016, Electronic Imaging, San Francisco—Carlos Eduardo Rodriguez-Pardo from the University of Rochester described a procedure for calibrating displays with more than the standard 3-color displays. The challenge is to provide a display that still has a continuous color spectrum. The current mode of 3-color displays has some issues with realistic matching to human vision. [...]

August 11, 2015, Siggraph, Los Angeles– Sebastian Sylwan from Felix & Paul Studios moderated this panel with panelists including Michael Whipple from Sony Pictures Entertainment, Alex Fry, compositing and color pipeline supervisor (“The Lego Movie”, “The Great Gatsby”), Chris Davies, technical director, Skylab (“Chappie”, “Elysium”), Marie Fetiveau from Rodeo FX . The main issue is [...]

June 16, 2015, SMPTE Entertainment Technology in the Internet Age, Stanford, CA—Lars Borg from Adobe describes some of the differences between standard dynamic range and high dynamic range workflows. These new specifications calling for wider color gamut and higher dynamic range will impact content workflows. Current HD TV is based on BT 709 to provide [...]

June 16, 2015, SMPTE Entertainment Technology in the Internet Age, Stanford, CA—Pat Griffis from SMPTE talked about the changes coming to TV and other video images. The advent of 4k and 8k sets will change more than the basic picture. An obvious development in the higher resolution TV sets is the increase in the number [...]

June 4, 2015, Society for Information Display Symposium, San Jose, CA—Karlheinz Blankenbach from Pforzheim University in Germany presented the results of studies comparing flat and curved TVs. The key parameter they measured was viewing-angle degradation and reflections. The ability to manufacture concave curved displays may provide advantages compared to flat and convex displays of the [...]

March 19, 2015, GPU Technology Conference, San Jose, CA—Thad Beier from Dolby talked about the coming changes in the video landscape to move towards higher dynamic range for the displays. The advent of 4k or ultra-high definition TV sets requires more than just increasing the number pixels, but needs more dynamic range and color gamut. [...]

March 4, 2015, Game Developer Conference, San Francisco—Viktor Lidholt from Spritebuilder talked about techniques for advanced visual effects in 2-D games. Visual effects come from things like sprites, color, blur and bloom, and distorted polygons. In addition, the use of particles and shader effects add much to a game. All of these effects have to [...]

January 2015, The new Common Core guidelines for math and science seem to be flawed. At the middle school levels, the guidelines call for students to show mastery of the content by being able to prove that a digital representation is the best one. This contention might be true if you are talking bit-level accuracy [...]

August 5, 2014, Emerging Display Technology Conference, San Jose, CA—A panel looked at the other system-level issues for video images. Pete Ludé from Mission Rock Digital moderated the group. Panelists were Julian Carey from Intematix, Veeral Hardev from Nanosys, Seth Coe-Sullivan fro QD Vision, Jimmy Kim from NPD DisplaySearch, and Roland Vlaicu from Dolby. Ludé [...]
