8.9.2 Reverse Y
(acA2000-165 and acA2040-90 Only)
The reverse Y feature is a vertical mirror image feature. When the reverse Y feature is enabled, the
lines in a captured image will be swapped top-to-bottom. This means that the top line, in the image
will be swapped with the bottom line, the next-to-top line will be swapped with the next-to-bottom
line. and so on.
Figure 102 shows a normal image on the left and, and an image captured with reverse Y enabled
on the right.
Using ROIs with Reverse Y
You can use the ROI feature when using the reverse X feature. Note, however, that the position of
an ROI relative to the sensor remains the same regardless of whether or not the reverse Y feature
is enabled (see
Figure 103 ).
As a consequence, an image ROI will display different images depending on whether or not the
reverse Y feature is enabled.
