US patent US10.497.737 entitled “enhanced dynamic range imaging” was granted on Dec 3, 2019.
It describes a pixel and methods to reach a very high dynamic range (HDR) by integrating the same photo charge on multiple capacitors synchronously. The concept reminds other Caeleste HDR methods (patents US9.780.138, US9.699.398, US9.819.882, BE1023468), yet uses a conceptually different approach.
