  1. Do you know if the pixel uses the ISOCELL technology?

  2. I don't know, but if not, ISOCELL technology is not state of the art technology.

  3. How are HDR videos with no shutter lag or post-processing (I supossse no use of ISP) generated?

    1. Check the patent US6,115,065 having Caltech as the assignee. However, according to the patent text the actual owner of the patent is NASA which funded the research. Just lately Samsung announced that it had made a licensing agreement of NASA technology...

    2. Caltech is the owner of this patent. All the major image sensors suppliers have licensed a portfolio of image sensor patents from Caltech, based on the CMOS APS work at JPL during the 1990's.

    3. In the beginning of the patent US6,115,065 it is clearly stated that:

      "The invention described herein was made in the performance of work under a NASA contract and is subject to the provisions of Public Law 96-517(35 USC 202) in which the Contractor has elected to retain title."

      Sounds rather schizophrenic that NASA would have "elected to retain title" while Caltech would be the owner of the patents. It just doesn't make any sense.

    4. You are reading this wrong. The contractor to NASA (US Govt.) is Caltech/JPL. So, Caltech has elected to retain the title under the Bayh Dole act of 1980. Hopefully this will make more sense to you.

    6. Thank you both very much for the information.

      Is there any official information indicating the use of this patent allowing this new realtime HDR video system in Samsung Galaxy S5, in order to properly mention this fact in articles or books?

  4. I think when they say no post-processing they meant no need to process it by end users themselves.
