Functional Description (continued)
2.0 WINDOWING
The integrated timing and control circuit allows any size window
in any position within the active region of the array to be read out
with a 1x1 pixel resolution. The window read out is called the
“ Display Window ”.
A “ Scan Window ” must be defined first, by programing the start
and end row addresses as shown in Figure 13. Four coordinates
(start row address, start column address, end row address &
end column address) are programmed to define the size and
location of the “ Display Window ” to be read out ( see Figure 13 ).
2.2 Programming the scan window (mode b)
To programme the scan window in mode b, bit 0 of the Scan
Window LSB Register (SROWLSB). In this mode the binary
value of scan window start and end row addresses are given by
scan row start address (bin) = [SwStartRow, SwStartRowLsb]
scan row end address (bin) = [SwEndRow, SwEndRowLsb]

2.3 Updating the Scan Window
After the “ Scan Window ” coordinates have been programmed,
the UpdateSettings bit in the UPDATE register should be set.
The timing and control circuit will set the new “ Scan Window ” at
Notes:
Note a:
Note b:
Note c:
Note d:
The “ Display Window ” must always be defined within
the “ Scan Window ”.
By default the “ Display Window ” is the complete array.
The end column address of the “Display Window”
cannot be smaller than 3F hex (63 Decimal).
New “ Scan Window ” coordinates only take effect at
beginning of the next frame and reset the UpdateSettings bit in
the UPDATE register.
2.4 Programming the Display Window
Five register (DROWS, DROWE, DCOLS, DCOLE and DWLSB)
are provided to program the display window as described in the
register section of this datasheet.
the beginning of the first frame after the UpdateSet-
tings bit is set in the UPDATE register.
2.1 Programming the scan window (mode a, default)
Two registers (SROWS & SROWE) are provided to program the
size of the scan window. The start and end row address of the
scan window is given by:
scan row start address = (2* SwStartRow) + SwLsb
scan row end address = (2* SwEndRow) + 1 + SwLsb
Where:
SwStartRow
is the contents of the Scan Window start row
register (SROWS)
SwEndROW
is the contents of the Scan Window end row reg-
ister (SROWE)
SwLsb
is bit 6 of the Display Window LSB register
(DWLSB)
This mode is provided for backward compatibility with the
LM9627 and LM9617 CMOS image sensors.
