Abstract
A video conversion system receives a luminance image and a chrominance image of a video image. The video conversion system vertically scales the luminance image and the chrominance image. The video conversion system then horizontally scales the video image based on the vertically scaled luminance image and the vertically scaled chrominance image to generate a scaled video image.
Claims38
A system for scaling a video image, comprising:
- a first vertical scaling module configured to vertically scale a luminance image of the video image;
- a second vertical scaling module configured to vertically scale a chrominance image of the video image;
- and
- a horizontal scaler in communication with the first vertical scaling module and the second vertical scaling module, the horizontal scaler configured to horizontally scale the video image based on the vertically scaled luminance image and the vertically scaled chrominance image to generate a scaled video image.
