Panorama
The Panorama feature is a non-linear stretch that can be applied only to a 4:3 video source. The panorama
stretches the picture with minimal perceptual distortion in the center of the screen. This mode can be turned ‘On’ or
‘Off’. Additionally this feature can be accessed in the IAR presets and it is titled ‘4:3 Stretch’.
Zoom
The Zoom function zooms in on or magnifies the image on your display. The minimum zoom is 100%, (no zooming);
the maximum zoom is 150% (zoom magnification factor of 1.5X).
•
Horizontal Zoom Control: Push the Enter button to show the current Zoom setting. Push the Up and Down
button to increase or decrease the zooming factor.
•
Vertical Zoom Control: Push the Enter button to show the current Zoom setting. Push the Up and Down button to
increase or decrease the zooming factor.
Pan
The Pan function allows the image to be shifted up, down, left and right. Note that the Pan function can only be used
after the image has been zoomed to any value greater than 100%.
•
Horizontal Pan Control: Push the Enter button to show the current Pan setting. Push the Up button to pan to the
right. Push the Down button to pan to the left.
•
Vertical Pan Control: Push the Enter button to show the current Pan setting. Push the Up button to pan up. Push
the Down button to pan the image down.
Borders
The Borders function allows you to add horizontal and/or vertical borders around the image. These borders obscure
part of the input image. Certain input-to-output aspect ratios already result in left/right or top/bottom border being
added. This control allows the system-generated borders to be extended, or for borders to be added when none
exist. As the borders are adjusted (see below) theDreamScaler3 temporarily increases the gray level of the borders
so that they are visible during the adjustment process. The level will return to normal after the adjustment has
ceased.
•
Horizontal Border Control: Push the Up button to move the left and right borders towards the middle of the
image, increasing the border width and cutting off the sides of the input image. Push the Down button to move
the left and right borders away from the image and decreases their width. If there are system-generated left/right
borders already present (for example, when the input aspect ratio is 4:3 and the output aspect ratio is 16:9), the
border width cannot be decreased beyond the base width created by the aspect ratio conversion.
•
Vertical Border Control: Push the Up button to move the top and bottom borders towards the middle of the
image, increasing the border height and cutting off the sides of the input image. Push the Down button to move
the top and bottom borders away from the image and decrease their height. If there are system-generated top/
bottom borders already present (for example, when the input aspect ratio is 16:9 and the output aspect ratio is
4:3), the border height cannot be decreased beyond the base height created by the aspect ratio conversion.
Borders are automatically added by the system when the Active Input Aspect Ratio is not the same as the Output
Aspect Ratio as explained earlier in this guide. However you can add more borders using the Borders menu.
Presets
You can specify the Input Aspect Ratio by using the Presets or Manually.
