Sony Global Shutter CMOS Sensor Features in Video

Point Grey published a nice Youtube video presenting the newly announced Sony IMX174 global shutter sensor and its spec. Point Grey appears to be the early adapter of the sensor, as it already used in its Grasshopper camera. The key specs are:
  • DR - 73dB
  • Peak QE @ 525nm - over 70%
  • Read noise - 6e-

Thanks to MJ for the link!

At ISSCC 2012, Sony presented a 5MP, 5.86um pixel sensor with global shutter that looks quite similar to IMX174 in terms of pixel technology, albeit resolution, frame rate and other parameters are not the same:

"An 83dB-dynamic-range single-exposure global-shutter CMOS image sensor with in-pixel dual storage"

  1. So, it's a charge domain global shutter. Who holds the patent of this technology?

  2. Could be my patent which has a 1994 priority date: E.R. Fossum, “Active pixel sensor array with electronic shuttering,” US Patent No. 6,486,503 and which is assigned to Caltech and licensed to most of the big players.

  3. 70% QE @ 525 nm is impressive. Does this sensor use Bayer CFA or some other novel method? Is this a BSI sensor with ulenses?

  4. Mono only so far, so no Bayer

    are there no other camera maker with this same sensor?
