An electronic picture stabilizer includes a microcomputer which determines whether or not each of detection areas is a valid area or invalid area. If the detection areas adjacent in a vertical direction are invalid areas, the detection areas are moved so as to maximize a distance between the detection areas adjacent in the vertical direction, and if the detection areas adjacent in a horizontal direction are invalid areas, the detection areas are moved in a manner that a distance between the detection areas adjacent in the horizontal direction becomes maximum. If the number of the invalid areas is a predetermined value, the detection areas are moved at four (4) corners of an image field. By moving the detection areas, the invalid areas become valid areas. If all the detection areas continuously become the valid areas during a predetermined number of fields, the detection areas are returned to their initial positions.
