Claim One:
1. A motion vector detection apparatus, comprising: reference frame block feature extraction means for dividing a reference frame block into a first plurality of minor blocks and for determining respective reference frame matching elements for each of the minor blocks of said first plurality, said respective reference frame matching elements representing odd-field and even-field pixels forming the corresponding minor blocks of said first plurality; search frame block feature extraction means for dividing a search frame block into a second plurality of minor blocks and for determining respective search frame matching elements for each of the minor blocks of said second plurality, said respective search frame matching elements representing odd-field and even-field pixels forming the corresponding minor blocks of said second plurality; matching means for detecting a search frame block which best matches said reference frame block on the basis of said reference and search frame matching elements provided from said reference frame block feature extraction means and said search frame block feature extraction means, respectively; adding means for receiving from said matching means the matched result corresponding to said odd-field pixels of said reference and search frame blocks and the matched result corresponding to said even-field pixels of said reference and search frame blocks and adding the received.
