摘要：An image motion vector detection device, which can detect an image motionvector with reduced amount of computation, includes means (2H) for extracting a

predetermined number of row data from one frame of image; means (3H) for filtering therow data for edge extraction; means (5H, 6H, 7H) for shifting each of filtered row data of

a current frame by the number of pixels based on the filtered row data and a firstthreshold, and integrating each of the shifted row data; means (8H) for determining ahorizontal motion vector in accordance with an output of the shifting/integrating means;means (2V) for extracting a predetermined number of column data from the one frame ofimage; means (3V) for filtering the column data for edge extraction; means (5V, 6V, 7V) forshifting each of filtered column data of the current frame by the number of pixels basedon the filtered column data and a second threshold, and integrating each of the shiftedcolumn data; and means (8V) for determining a vertical motion vector in accordance withan output of the shifting/integrating means.
