A plurality of control magnetic poles 33n-34n are provided in each selection unit of a selection actuator, and the upstream control magnetic poles 33n, s and downstream control magnetic poles 34n, s are controlled independently based on the relative positions thereof to selectors. The invention further relates to a method for manufacturing such an emblem. A plurality of stacked gate layers are formed on a semiconductor substrate, wherein each stacked gate layer extends in a predefined direction and is substantially parallel to other stacked gate layers. In addition, it is possible to solve the problem of increased calculation complexity caused from using an extended Gabor wavelet filter and to implement robust face recognition which is excellent in dealing with a change in expression and illumination.
