array.
2.1.6 WOI Sub-sampling Control
The WOI can be sub-sampled per user control. The
user can read out the pixel data in either monochrome
or bayer pixel space in four different sampling rates in
each direction: full, 1/2, 1/4, or 1/8. The user controls
the subsampling via the
(Table 25), on page
sub-sampling is shown in
2.1.7 CFCM Frame Rate and Integration Time
In addition to the minimum time required to readout the
selected resolution and WOI, the user has the ability to
control the frame rates while operating in CFCM. This is
done by varying the size of a Virtual Frame surrounding
the WOI. Please refer to
tion of the Virtual Frame and its relationship to the WOI.
