Figure 5. Line Selection and Reset Sequence
Latching in a Y- address selects the addressed row and connects
the pixel outputs of that row to the column amplifiers. Through
the sequence of the S and R pulse and the reset pulse in
between the pixel output signal and reset level are sampled and
produced at the output of the column amplifier (to do the FPN
double sampling correction).
At this time horizontal read out of the selected row is started and
another row is reset to effectuate reduced integration time
(electronic rolling shutter).
