Abstract
A video scaling process system, wherein the high frequency components of the input video sequence are compensated for, prior to video scaling. The video scaling system includes a pre-compensator for compensation of the high frequency components of the input video sequence, and a video scaler. The pre-compensator includes a high frequency component extractor, a noise detector and a shoot suppressor. The high frequency component extractor extracts the high frequency compensation component from an input video sequence. The noise detector adjusts the gain of the compensation to avoid the enhancement of the noise component. The shoot suppressor further adjusts the gain of the compensation to avoid shoot artifacts. The adjusted high frequency compensated video is added back to the input video. The pre-compensated video sequence is then passed through a video scaler to obtain the scaled video. As such, the sharpness of the scaled video is maintained or even enhanced.
