Resizer
Chapter 4 Keys
Two-Dimensional Transformations
and Rotation of Keys
When the screen aspect ratio is 4:3 in HD format, when the
resizer is used to shrink a video image, this is applied to the
16:9 screen including the added video on the left and right
sides. Use the crop function as required to extract the 4:3
image.
Menu operations for key shrinking,
magnification, rotation and movement
As an example, for key 1 of the M/E-1 bank, use the
following procedure.
1
In the M/E-1 >Key1 >Processed Key menu (1115),
press [Resizer], turning it on.
2
Adjust the following parameters.
When [Rotation Enable] is turned on, the parameters
change as follows.
a) [X] is turned on in the <Rotation> group of the Rotation menu.
b) [Y] is turned on in the <Rotation> group of the Rotation menu.
When “Rotation Enable” is turned on, the movement
range of the center of the image is limited to the top
and bottom edges of the image frame.
Functions that cannot be used with key rotation
When “Rotation Enable” is turned on, aspect ratio
parameters (Aspect X, Aspect Y, Aspect Ratio) cannot be
adjusted. In addition, defocus cannot be used.
