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.

More accurate frame-rate conversion is carried out in a simpler circuit configuration. Search areas SA+1 and SA−1 in each of which the pixel facing the interpolation position P0 of a pixel in an interpolation frame is taken as a central pixel are set in the current frame and immediately previous frame of an image signal, a set of pixels point-symmetrical to the interpolation position P0 in each of the search areas SA+1 and SA−1 are defined as pixel pairs, and differential luminance values between the individual pixels in the pixel pairs are calculated for each pixel pair. Of all these pixel pairs, only that having the minimum absolute differential value is selected as interpolation pixel pair, an interpolation frame is generated from the current frame and the immediately previous frame on the basis of the interpolation pixel vector of that interpolation pixel pair.
