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.
HDTV (1080i)
Images of 1920 × 1080 pixels in size are exactly the size which fills the full screen.
Like SDTV, images are placed with the upper left of the screen as the origin. When an image is smaller or larger than the screen, processing is the same as for SDTV.
Since the pixel ratio of the HDTV format is 1:1, files created on computers are imported in their original shapes.
The following table shows the image sizes which exactly fill the full screen for the various signal formats.
Signal format | Image size (H × V) |
|
|
480i/59.94 | 720 × 487 |
|
|
576i/50 | 720 × 576 |
