7710ARC Series - SD Aspect Ratio Converter

If the input image aspect ratio is smaller than the output image aspect ratio the entire width of the input

image is used and only a portion of the height is used.

6.2.2.2. Stretching (Squeezing)

In stretching mode, the input image is stretched (squeezed) in one dimension so that it occupies the entire

output image. In this mode, often referred to as "anamorphic mode", the aspect ratio of objects inside the

output image areas is distorted (i.e. circles become ellipses, squares become rectangles, etc.).

If the input aspect ratio is greater than the output image aspect ratio, typically the entire height of the input

image is used as is and the width of the input image is compressed horizontally making objects "look"

taller and skinnier.

If the input image aspect ratio is smaller than the output image aspect ratio, the entire width of the input

image is used as is and the height of the input image is squeezed vertically making objects "look" shorter

and fatter.

In filling mode, the input image is resized in both dimensions to fit the output image preserving the input

image aspect ratio (i.e. circles remain as circles, squares remain as squares, etc.). The portions of the

destination frame that are not occupied by the scaled input image are filled with a "bar" that can either be a

flat field image or, on the 7710ARC-F model, the bar may be filled with a background image.

If the input image aspect ratio is greater than the output image aspect ratio, the width of the input image

completely fills the width of the output image and the input image height is scaled by the same amount.

The portions of the height of the destination frame that are not occupied by the scaled input image are

filled with horizontal bars. This destination frame configuration is referred to as a "letterboxed" image.
