Abstract
A single line buffer in a motion video card is used for both vertical reduction of the pixel image before storage in a video memory buffer and vertical expansion of the pixel image after being outputted by the video memory buffer. When the desired display size is smaller than the original pixel image size, then the line buffer is used by the input pipeline to reduce the image. When the desired display size is larger than the original pixel image size (or larger than the image stored in the memory buffer), then the line buffer is used by the output pipeline to enlarge the image.
