MOTOROLA
4.0 Active Window of Interest Control
The pixel data to be read out of the device is defined as
a ‘Window of Interest’ (WOI). The window of interest
can be defined anywhere on the pixel array at any size.
The user provides the upper-left pixel location and the
size in both row and column depth to define the WOI.
The WOI is defined using the WOI Pointer, WOI Depth,
and WOI Width registers,
Table 41 on page
torial representation of the WOI within the active pixel
array.

5.0 Active Window Sub-sampling Control
The user can further control the size of the Active Win-
dow that is read out by sub sampling the already de-
fined Active Window Of Interest (See
Interest Control” on page
pixel data to be readout in 1 pixel or 2 pixel increments
depending if you are subsampling in either mono-
chrome (1 pixel) or bayer pixel (2 pixel) space in four dif-
ferent sampling rates in each direction: full, 1/2, 1/4, or
1/8. The user controls the subsampling via the
sample Control Register, (Table 32), on page
An example of Bayer space sub-sampling is shown in
