That is ingenious. By having alternating small and large photosensitive areas coupled to fixed size charge storage devices, you get high and low sensitivity pixels with high commonality.<p>In theory you could have an exponential series to have even more dynamic range.<p>Or alternatively, if you use powers of two for the sizes, you could use 1-bit sensors, though you probably couldn&#x27;t do a high bit depth that way. But it&#x27;d be extremely fast, as there wouldn&#x27;t need to be a real A&#x2F;D conversion. Maybe concentric pixels of varying sizes...
