Abstract:
A method for controlling a pixel may include first and second photosites, each having a photodiode and a charge-transfer transistor, a read node, and an electronic read element, all of which are common to all the photosites. The method may include an accumulation of photogenerated charges in the photodiode of the first photosite during a first period, an accumulation of photogenerated charges in the photodiode of the second photosite during a second period shorter than the first period, a selection of the signal corresponding to the quantity of charges accumulated in the photodiode of a photosite having the highest unsaturated intensity or else a saturation signal, and a digitization of the selected signal.
