In this mode, the sensor is readout in the same way as for non-destructive readout.
However, electronic shutter control is not possible in this case, i.e. the minimal
(integration) time between two readings is equal to the number of lines that has to be
read out (frame read time). The row lines are clocked simultaneously (left and right
clock pulses are equal).

In mode 2, it is possible to have a shorter integration time than the frame read time.
Rows are alternating read out with the left and right pointer. These two pointers can
point to two different rows (see I
NT
_
TIME
register). The (integration) time between
two readings of the same row is equal to the number of lines that is set in the
I
NT
_
TIME
register times 2 plus 1 and is minimal 1 line read time. In setting 3, the row
that is read out by the left pointer is reset and read out (first Y_
CLOCK
), the row that is
read out by the right pointer is read out without resetting (second Y_
CLOCK
). In
setting 4, both rows are read out without resetting (on the first Y_
CLOCK
the row is
read out by the left pointer; on the second Y_
CLOCK
the row is read out by the right
pointer).
For both modes, the signals are read out through the same path as with destructive
readout (double sampling) but the busses that are carrying the reset signals in
destructive readout, are in non-destructive readout set to the voltage given by

3.9.2.a.3 Reset_black (bit 3)
If R
ESET
_
BLACK
is set to 1, each line is reset before it is read out (except for the row
that is read out by the right pointer in NDR mode 2). This might be useful to obtain
black pixels.
3.9.2.a.4 Fast_reset (bit 4)
The fast reset option (F
AST
_
RESET
= 1) might be useful in case a camera shutter is
used. The fast reset is done on a row-by-row basis, not by a global reset. A global
reset means charging all the pixels at the same time, which may result in a huge peak
current. Therefore, the rows can be scanned rapidly while the left and right shift
registers are both controlled identically, so that the reset lines over the pixel array are
driven from both sides. This reduces the reset (row blanking) time (when F
AST
_
RESET
= 1 the smallest X-granularity can be used). After the row blanking time the row is
reset and Y_
CLOCK
can be asserted to reset the next row.
