Title: Image movement information extracting device
Inventor: INOUE IKUO
IPC: H04N19/423
Filed: 1987-02-26
Abstract: PURPOSE:To accurately detect a moving vector with less operation quantity by extracting a candidate for the moving vector with binary correlation arithmetic operation and executing multivalued correlation arithmetic operation for the obtained candidate. CONSTITUTION:Image data respectively written in a present frame buffer memory 101 and a last frame buffer memory 102 are bianarized by binarizing circuits 103 and 104. The correlation of the bianarized output of the binarizing circuits 103 and 104 is obtained by a binary correlation arithmetic operation part 105. The some, for example, three output among the output of which correlation are stronger are judged as the candidates for the moving vector by a order judgement part 106 and extracted. The multivalued correlation arithmetic operation for these extracted candidates is executed by a multivalued correlation arithmetic operation part 108 and the extracted candidate of which correlation is the strongest among the candidates which the multivalued correlation arithmetic operation is executed for is decided as the moving vector. Thus the moving vector can be accurately detected with the less operation quantity.
