7.15.3.2 Positioning of an Auto Function ROI Relative to the Image ROI

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