A remote controlled inspection vehicle provides interchangeable modules, permitting the vehicle to be easily configured to perform a wide variety of tasks. When the input image is given as a frame buffer that is not encoded, the present invention extracts motion vector by performing block motion matching operation, and when the input image is a digitally encoded bit stream, it extracts motion vectors from the decoded data. Thus, electric potentials at gate electrode and scanning lines 11 are substantially equal in magnitude to those at semiconductor layer 21. The antenna may also be implemented in non-differential designs. The mask layer is then etched to form first mask patterns below the first patterns and a second mask pattern below the second pattern. A corresponding domestic appliance having a panel is also disclosed.
