The
Internal Timing Control Register; Table 28
, is used
to define the size of internal timing pulse widths. In de-
fault, both
shs
and
shr
are 6 MCLK
’
s wide. The user is
strongly encouraged to write an 00
h
to this register; thus
making these pulse widths 16 MCLKs wide.
5.5.2 Programmable
“
Window of Interest
”
The WOI is defined by a set of registers that indicate the
upper-left starting point for the window and another set
of registers that define the size of the window. Please
refer to
Figure 6, on page 7
for a pictorial representation
of the WOI within the active pixel array.
The WOI Row Pointer;
wrp
[8:0] (
Table 29
and
Table
30
), and the WOI Column Pointer;
wcp
[9:0] (
Table 31
and
Table 32
), mark the upper-left starting point for the
WOI.
The WOI Row Pointer;
wrp
[8:0], has a range of 0
d
to
511
d
whereas the WOI Column Pointer;
wcp
[9:0] has a
usable range of 0
d
to 703
d
. The pointer can be placed
anywhere within the active pixel array.
The WOI Row Depth;
wrd
[8:0] (
Table 29
and
Table 30
),
and the WOI Column Depth;
wcd
[9:0] (
Table 31
and
Table 32
), indicate the size of the WOI.
The WOI Row Depth;
wrd
[8:0], has a range of 0
d
to
511
d
whereas the WOI Column Depth;
wcd
[9:0], has a
range of 0
d
to 703
d
.
The user should be careful to create a WOI that con-
tains active pixels only. There is no logic in the sensor
