About import image size
Pay attention to the following, depending on the signal format which you use.
The image size which exactly fills the full screen is 720 × 487 in the 480i/
59.94 format, and 720 × 576 in the 576i/50 format.
The following figure shows how an import image is processed when the 480i/
59.94 format is used.
Images are placed with the upper left of the screen as the origin.
When an image is smaller than the screen, the remainder of the screen is filled
with black. When it is larger, parts which extend beyond the screen are
discarded.
No pixel ratio conversion is performed when images are imported for the
SDTV format.
When the signal format is 480i/59.94, if you create an image with a size of 720
× 540 on a computer and then import it just as it is, the image will be too tall.
To maintain the shape of the image, first create it as a 720 × 540 image and then
use computer software tools to compress the vertical dimension to 487 pixels
before importing it.
The same is true when the 576i/50 format is used.
