7.8.2 Auto Function AOIs
Each auto function uses the pixel data from an Auto Function AOI for automatically adjusting a
parameter value and, accordingly, for controlling the related image property. Some auto functions
use their own individual Auto Function AOI and some auto functions share a single Auto Function
AOI.
Each Auto Function AOI must be set separately from the AOI that is used to define the size of
captured images (Image AOI). You can specify a portion of the sensor array and only the pixel data
from the specified portion will be used for auto function control. Note that an Auto Function AOI can
be positioned anywhere on the sensor array and unlike the image AOI, will not be automatically
centered.
An Auto Function AOI is referenced to the top left corner of the sensor array. The top left corner of
the sensor array is designated as column 0 and row 0 as shown in Figure 33.
The location and size of an Auto Function AOI is defined by declaring an X offset (coordinate), a
width, a Y offset (coordinate), and a height. For example, suppose that you specify the X offset as
14, the width as 5, the Y offset as 7, and the height as 6. The area of the array that is bounded by
these settings is shown in Figure 33.
Only the pixel data from within the Auto Function AOI defined by your settings will be used by the
related auto function.
