摘要： A motion vector detection apparatus is disclosed capable of detecting accurate motion vectors from between a previous frame of image and the presently displayed frame of image even in edge regions of the frames where inaccurate motion vectors would normally tend to be detected. A motion vector-detecting portion reads in an image signal from the signal input portion as well as image signals entered through first through third frame memories. Processing for detecting motion vectors is performed, based on four frames entered in synchronism to the motion vector-detecting portion out of the frames forming the image signals. Vectors produced between the image signal from the first frame memory delayed by one frame relative to the image signal from the signal input portion and the image signal from the second frame memory delayed by two frames relative to the image signal from the signal input portion are detected as motion vectors.
