Claims
- 1. A motion vector detection apparatus, comprising:
- reference frame block feature extraction means for dividing a reference frame block into a plurality of minor reference blocks and for determining a value for a frame matching element, which value represents pixels constituting each of said minor reference blocks;
- search frame block feature extraction means for dividing a search frame block into a plurality of minor search blocks and for determining a value for a frame matching element, which value represents pixels constituting each of said minor search blocks;
- frame motion vector generating means for generating a frame motion vector in order to search for a search frame block which best matches said reference frame block, based on said frame matching elements provided from said reference frame block feature extraction means and said search frame block feature extraction means; and
- switching means for switching said reference frame block feature extraction means and said search frame block feature extraction means to a first feature extraction to extract a high-level component or a second feature extraction which does not extract said high-level component, based on movement information.
- 2. A method for detecting a motion vector, comprising the steps of:
- performing reference frame block feature extraction to divide a reference frame block into a plurality of minor reference blocks and to determine a value for a reference frame matching element, which value represents pixels constituting each of said minor reference blocks, said reference frame block feature extraction being selected from a first feature extraction to extract a high-level component and a second feature extraction which does not extract said high-level component, based on movement information;
- performing search frame block feature extraction to divide a search frame block into a plurality of minor search blocks and to determine a value for a search frame matching element, which value represents pixels constituting each of said minor search blocks, said search frame block feature extraction being selected from said first feature extraction to extract said high-level component and said second feature extraction which does not extract said high-level component, based on movement information; and
- generating a frame motion vector in order to search for a search frame block which best matches said reference frame block, based on said reference and search frame matching elements.
