Abstract
A method for reading a pixel, including at least two integration periods, at least one of said periods including at least one integration sub-period, wherein an output value of the pixel is determined by taking into account the amounts of photogenerated charges contained in the pixel at the end of each of said periods and the amount of photogenerated charges stored in a photodiode of the pixel beyond a threshold during said at least one sub-period.
