10.9.2.2 Relative Positioning of an Auto Function AOI
The size and position of an Auto Function AOI can be, but need not be, identical to the size and
position of the Image AOI. Note that the overlap between an Auto Function AOI and the Image AOI
determines whether and to what extent the auto function will control the related image property.
Only the pixel data from the areas of overlap of an Auto Function AOI and the Image AOI will be
used by the auto function to control the image property of the entire image.
Different degrees of overlap are illustrated in Figure 60. The hatched areas in the figure indicate
areas of overlap.
 If the Auto Function AOI is completely included in the Image AOI (see (a) in Figure 60), all pixel
data from the Auto Function AOI will be used to control the image property.
 If the Image AOI is completely included in the Auto Function AOI (see (b) in Figure 60), only
the pixel data from the Image AOI will be used to control the image property.
 If the Image AOI only partially overlaps the Auto Function AOI (see (c) in Figure 60), only the
pixel data from the area of partial overlap will be used to control the image property.
 If the Auto Function AOI does not overlap the Image AOI (see (d) in Figure 60), the Auto
Function will not control the image property. For details, see the sections below, describing the
individual auto functions.
We strongly recommend completely including the Auto Function AOI within the
Image AOI, or, depending on your needs, setting identical positions and sizes for
the Auto Function AOIs and the Image AOI.
You can use auto functions when also using the reverse X and reverse Y mirroring
features. For information about the behavior of Auto Function AOIs when also
using the reverse X or reverse Y mirroring feature, see the "Mirror Image" section.
