<p>PROBLEM TO BE SOLVED: To improve the converted picture quality of an oblique line and an oblique edge part by judging whether a main spatial directivity in the small area detected by each small area of a picture is significantly intense compared with other spatial directivity as significant intensity, emphasizing the main spatial directivity of the picture in the small area based on the judging result and detecting the motion vector of the emphasized picture. SOLUTION: A motion vector detector A detects the main spatial directivity (k) of a picture from a television picture signal by a directivity detecting circuit 1. Next, a significance judging circuit 2 outputs the degreeαof the significance of the directivity (k). In addition, a directivity emphasizing circuit 3 outputs a television picture signal Lp (k) emphasizing the directivity based on the directivity (k). Next, a mixing circuit 4 respectively multipliesα, (1-α) to the signal Lp(k) and the television picture signal and then adds. Then, based on the adding result, a motion vector detecting circuit 5 detects the horizontal component and vertical component of the motion vector.</p> |
