Method and apparatus for detecting motion |
摘要 |
There is disclosed a method and apparatus for detecting motion by a video encoder. The method starts with dividing a target block whose motion is to be detected into blocks at different pixel positions. A reference image block is extracted from a reference image. The degrees of similarity of the blocks to the reference image block are simultaneously calculated by a calculating unit. A block having the highest degree of similarity is determined, based on their degrees of similarity. A vector corresponding to the determined block is taken as a motion vector representing the block.
