IISW 2015 Program: All-Pixel PDAF, Global Shutter Stacked Sensors, and More

2015 International Image Sensor Workshop (IISW) to be held on June 8-11, 2015 in Vaals, The Netherlands, publishes its program. There is quite a lot of interesting papers. Just to name a few of the broader public interest:

Sony and Canon present image sensor with phase detection autofocus in ALL pixels:

  1. In addition to the regular IISW technical program, there will be a Keynote Talk by Peter JW Noble on "History of the creation of MOS vision sensor arrays and associated topics and what does – or should - the future hold?"

    Peter JW Noble pioneered the first "3T" APS pixels in the late 1960's just before the CCD was invented and also introduced the first buried photodiode - a bit like a partially pinned photodiode. We are truly fortunate and honored to be able to have him attend the meeting and make a presentation, much in the manner that Mike Tompsett, inventor of the CCD image sensor did at Snowbird in 2013.

    Awards at the 2015 IISW will include:

    The Walter Kosonocky Award (winners to be announced at the workshop)

    Peter JW Noble - (the new) 2015 IISS Pioneering Achievement Award

    Jerry Hynecek - 2015 IISS Exceptional Lifetime Achievement Award

  2. Why the title is on vision sensor ? 3t pixel is a simple image sensor , I think that vision sensor means sensor with information processing, extraction inside either pixels or close to the pixel.
    Other question for IISW comity is that some of these works have been presented in other conferences, why are they still be accepted ?
    Thanks !

    1. Well, when your contributions today are recognized 50 years from now as pioneering, we will also let you choose the title of your talk. I think vision sensor was not an uncommon way of speaking about those first solid-state image sensors in the late 1960's.

      Regarding the papers, I can't speak for the other technical program committee members, but I rank the papers according to my interest in hearing them be presented and being able to ask questions etc. directly of the author. Being previously presented to a limited image sensor technologist audience (even ISSCC) does not automatically mean they are not of interest. It is a workshop (not a normal conference) where most of us will share what we are working on and thinking about, and discuss it with other high-caliber technologists to get their thoughts. Some papers are rejected because they have been presented before and no one wants to hear them again. It just depends on the collective interest of the technical program committee. By the way, try digesting ~150 abstracts and ranking them. It is a lot of work and an imperfect process, and considering the TPC members and their regular job duties, it is amazing that they still volunteer their time to make the best possible program for our community.

  3. For the first point, I keep my opinion. The second point was a simple question that I would like to understand how this rule is interpreted. Personally I tried to publish each work once as original work. It's not a polemic.
    Thanks !

  4. Please regurlarly check-out the IISW program on the website of IISS, it changes now and then. And BTW, the workshop is completely SOLD OUT. It really does not make sense to contact me with the request to put your name on a waiting list. The waiting list is already way too long as well. Very sorry about that.
