Region of Interest (ROI) Controls
The Region of Interest parameters select a portion of the input picture that will
be used for scaling and/or positioning. The selected area can then be scaled to a
standard pillarbox or letterbox size and shape (On Square), or it can be set to a full
screen input image (On Full).
NOTE: On Full may cause image distortion if it is used to expand an odd-shaped region
of interest to full screen.
The ROI Setup mode allows you to preview the edges of your selected Region Of
Interest as you set it up. After selecting the desired region using the Setup Cursor,
you can take the region to air by setting Region Of Interest to On Square or On
Full.
The Setup mode is not required to operate the ROI feature. The edges of the
Region Of Interest can also be adjusted while in On Square or On Full modes
