You'd just run the reset curtains staggered with respect to each other and keep the read curtains aligned so that the read of each pair of pixels occurs during the same row time. You get 2 different exposures for a given bayer tile that can be combined in a LSBS fashion inline. They probably need a few row buffers and a lot of digital logic to make it work, but the amount of memory is not excessive. This technique is efficient in that the exposures can occur simultaneously, but dark pixels may loose nearly half their photons in some scenarios. This is the cost of doing it inline. - KFAnonymousnoreply@blogger.com
