IN A MOTION VECTOR DETECTION METHOD FOR DETECTION THE MOTION VECTOR OF A FIELD PICTURE CONFORMING TO THE INTERLACED SCANNING SYSTEM, A MOTION VECTOR OF A SECOND FIELD PICTURE. A SEARCH RANGE IN DETECTING THE MOTION VECTOR FOR A THIRD FIELD PICTURE IS COMPUTED BY COMPARING A FIELD-TO-FIELD DISTANCE BETWEEN A FIELD PICTURE TO BE REFERRED TO AND THE THIRD FIELD PICTURE AND FIELD-TO-FIELD DISTANCE BETWEEN THE FIRST FIELD PICTURE AND THE SECOND FIELD PICTURE. THE MOTIN VECTOR OF THE THIRD FIELD PICTURE IS DETECTED IN A SEARCH RANGED COMPUTED WITH A POINT INDICATED BY THE MOTION VECTOR OF THE SECOND FIELD PICTURE AS A START POINT TO REDUCE THE PROCESSING VOLUME IN DETECTING THE MOTION VECTOR FOR THE FILED PICTURES OF THE INTERLACED SCANNING SYSTEM.THE MOST ILLUSTRATIVE DRAWING IS (FIGURE NO.8). |
