Image Flip – Multi-ROI Mode
Image acquisition flips with multi-ROI enabled is implemented as follows:
• The first graphic below shows a simple multi-ROI of two areas, where the camera output is
composed of only those two areas.
• As shown in the second graphic, the multi-ROI implementation resizes the programmed ROI
areas so that the same exact image areas are output by the camera but flipped as
expected.
• Note that the ROI indexes do not transpose—just their size and offsets.
• All multi-ROI setup constraints remain as described in the previous section describing the
Multi-ROI mode.
