full-screen view while keeping the aspect ratio
unchanged.
ROI
Crop
Enlarges or reduces the incoming video so

Parameter Explanation
Size
Zoom
Scales the picture as a percentage, while
maintaining the aspect ratio.
If the aspect ratio has changed due to the
“Size H” or “Size V” settings, the picture
is scaled while keeping the aspect ratio
after the values were changed.
ROI
H
Sets the horizontal (H)/vertical (V) size in
pixels. The aspect ratio is not maintained.
ROI
V
Position
H
Adjusts the horizontal (H)/vertical (V)
position.
ROI
V
