VIDEO PROCESSING METHOD FOR DETERMINING POSITION OF REFERENCE BLOCK OF RESIZED REFERENCE FRAME AND RELATED VIDEO PROCESSING APPARATUS

摘要

A video processing method includes: receiving a motion vector of a prediction block in a current frame; performing a first motion vector scaling operation upon the motion vector to generate a first scaled motion vector; after the first scaled motion vector is generated, utilizing a motion vector clamping circuit for performing a first motion vector clamping operation upon the first scaled motion vector to generate a first clamped motion vector; and determining a position of a reference block of a reference frame according to at least the first clamped motion vector.
