The resolution of each axis can be set to four
different sampling rates: full, ,
, or
1
/
8
. Sub-
sampling the imager by
in both horizontal and
vertical directions results in only
1
/
16
of the pixels
being readout. The frame readout rate can
therefore be increased by 16x. The user controls
the sub-sampling via the Sub-Sample Control
Register (41
h
),
Table 28
on
page
56
. An example
of RGB Bayer space sub-sampling is shown in
Figure 9
. If the imager is set as a color imager
then the sub-sampling is done by reading out two
cols/rows and then skipping two. This prevents the
sub-sampling from breaking up a color kernel. If
the imager is set to Monochrome mode the sub-
sampling will skip every other col/row performing a
more uniform reduction is resolution. Activating
Sub-Sampling alone will not increase the Frame
Rate. The Frame Rate is controlled by the Virtual
Frame (see “
Virtual Frame (VF)”
). For example, if
Sub-Sampling is first turned on to
1
/
8
x
1
/
8
mode,
the WOI will shrink by
1
/
64
. To keep the Frame
Rate constant, the KAC-1310 fills in the rest of the
rows and columns with blanking pixels. The Virtual
Frame can now be reduced by 1/8 x 1/8 to take
advantage of the Sub-Sampled WOI. The Frame
Rate will now have increased by 64x with no
compromise to the field of view (in CFRS mode).

Virtual Frame (VF)
Changing the WOI does not change the Frame
Rate of the imager. This is done by varying the
size of a Virtual Frame surrounding the WOI.
Refer to
Figure 8
for a pictorial description of the
Virtual Frame and its relationship to the WOI.
The VF is a method for defining the horizontal and
vertical blanking (over clocking) in Frame
Readout. As the WOI is adjusted, the total Frame
Size is set by the VF. To maintain constant Frame
Rate, the KAC-1310 adjusts the number of
blanking pixels to account for changes in the WOI.
The VF can be set to any size. If the VF is greater
than the WOI then the readout is padded with
blanking pixels (invalid dark pixels). The WOI and
the VF may both be larger than the actual imager
size. In this case the WOI is also padded with
blanking pixels (invalid dark pixels).
Figure 8
illustrates a WOI smaller than the VF. If the WOI is
set larger than the VF, then the WOI will be
clipped by the VF and the Frame Rate will still be
equal to the VF size.

Integration Time
CFRS Integration Time
The Integration Time in CFRS is defined and
quantized by the time to read out a single row.
Once a Virtual Frame has been defined, the time
to read out one row can be calculated. Any integer
multiple of the Row Time (T
row
) can be selected.
The number of Row Times desired for integration
time is programmed into the Integration Time
