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 Figure 52 . The hatched areas in the figure indicate
areas of overlap.

If the Auto Function ROI is completely included in the Image ROI (see (a) in Figure 52 ), the
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 Figure 52 ), only
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 Figure 52 ), only the
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 Figure 52 ), the auto
function will not work .

The minimum overlap between Auto Function ROI and Image ROI is 4 × 4
pixels. If a lower overlap is set (e.g. 4 × 2 pixels), the related auto function will
not work .

Basler strongly recommends completely including the Auto Function ROI
within the Image ROI or choosing identical positions and sizes for Auto
Function ROI and Image ROI.
