A pixel’s integration time is defined by the number of
clock periods between a row’s reset and read operation. Both
the read followed by the reset operations occur within a row
period (TROW) where the read and reset may be applied to
different rows. The read and reset operations will be applied
to the rows of the pixel array in a consecutive order.
The coarse integration time is defined by the number of
row periods (TROW) between a row’s reset and the row read.
The row period is defined as the time between row read
operations (see Sensor Frame Rate).
