<p>PURPOSE:To remove a connection zone caused from the horizontal component, etc., of a plate frame apt to come into contact with the connection zone of a character, and to avoid the detection mistake of a plate zone by obtaining a vertical component and the horizontal component separately first of all, and after erasing the connection zone where size and an area deviates from a prescribed range in the horizontal component, superposing the vertical component and the horizontal component. CONSTITUTION:Since the connection zone caused from the horizontal component, etc., of the plate frame has a feature that it is long in a horizontal direction, at the time of obtaining a contrast picture, first of all, the vertical component and the horizontal component are obtained separately, and after erasing the connection zone where the size or the area deviates from the prescribed range in the horizontal component, the horizontal component is superposed on the vertical component. Thus, the connection zone caused from the horizontal component, etc., of the plate frame apt to come into contact with the connection zone of the character is removed so that the detection mistake of the plate zone is avoided.</p> |
