An image motion vector detection device, which can detect an image motion vector 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 the row 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 first threshold, and integrating each of the shifted row data; means (8H) for determining a horizontal 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 of image; means (3V) for filtering the column data for edge extraction; means (5V, 6V, 7V) for shifting each of filtered column data of the current frame by the number of pixels based on the filtered column data and a second threshold, and integrating each of the shifted column data; and means (8V) for determining a vertical motion vector in accordance with an output of the shifting/integrating means. |
