7.11.2 Reverse Y

For information about the availability of ReverseY on a specific camera model, see Table 41 on
page 191 and Table 42 on page 192.
Normal Implementation
The ReverseY 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 103 shows a normal image on the left and, and an image captured with ReverseY 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 104).
As a consequence, an image ROI will display different images depending on whether or not the
Reverse Y feature is enabled.
Auto function ROIs will behave analogously to image ROIs.
