    I don’t understand Japanese, but I used google translate. I guess it’s like “flat” Foveon: there is only one layer, but every pixel uses photoelectric effect like in Foveon. But upper layers don’t shade bottom layers. Probably this sensor uses two times more information than classic bayer which exclude 2/3 of light for each color.

      Use J-PlatPat instead:

      – go to this page https://www4.j-platpat.inpit.go.jp/eng/tokujitsu/tkbs_en/TKBS_EN_GM101_Top.action

      – enter the number of the patent, i.e. 2016-201400, in the second (from top to bottom) field on the right

      – click ‘Search’

      – click on the ‘JP,2016-201400,A’ hyperlink.

      You can then browse between ‘CLAIMS’, ‘DETAILED DESCRIPTION’ and ‘DRAWINGS’.
