Region of Interest
(ROI)
The
Region of Interest
parameters (14.0–14.4) select a portion of the input picture that will
be used for scaling and/or positioning. This feature can be useful for focusing in on
computer video that is less than full screen, such as the contents of a movie player
window. 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
.
Note that 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
14.0 Region of Interest
This parameter turns the Region of Interest settings
On
or
Off.
When enabled, the
ROI Left
,
Right
,
Top
, and
Bottom
controls (14.1–14.4) define the rectangular shape and position of
the ROI.
Interactions occur between ROI settings and other parameters:
• The
Region of Interest
menu is not displayed when
Active Format Description (AFD)
is in
control of the Conversion Mode. While downconverting, with
Downconvert Mode
set to
Auto AFD
, any values assigned for
Custom Size/Pos
parameters are ignored, and the
menus are hidden.
•
Custom Size and Position
settings work interactively with ROI, but
Custom Crop
settings
are disabled.
Custom Size/Pos
is also temporarily disabled while in the ROI
Setup
mode.
14.1 ROI Left
This parameter sets the left boundary of the ROI when parameter 14.0 is on.

This parameter sets the right boundary of the ROI when parameter 14.0 is on.
14.3 ROI Top
This parameter sets the top boundary of the ROI when parameter 14.0 is on.
14.4 ROI Bottom
This parameter sets the bottom boundary of the ROI when parameter 14.0 is on.
