OPERATION
Advanced Size and Position
— SUBMENU
This submenu consists of the
following options:
This
ACTIVE INPUT WINDOW:
read-only value indicates the
current size (i.e., area) of your
displayed data or "region of
interest" as defined by the
blanking controls. For example, if
you have blanked (cropped) 100 pixels from both the left and right edges of an
incoming source of 2048 x 1080, the remaining active input window will be 1848 x
1080. When using a video source at or , the default blanking of "0"
INPUT 3 INPUT 4
defines an active input window of 720 x 483.
BLANKING (TOP, BOTTOM, LEFT, and RIGHT):
Crop the image as desired so that unwanted
edges are removed from the display (changed
to black—see right). Blanking defines the
size of the Active Input Window, creating an
area of interest. Range of adjustment depends
on the source resolution and other factors for
your application.
NOTE: Blanking a PIP image resembles
zoom (see Figure 3.16). For example, left
Blanking zooms the right side of the PIP
image; Right Blanking zooms the left side.
There are no black bars. Figure 3.15. Blanking of a
