A system for controlling a motor may include a motor driver circuit for driving a camera motor. A laminated body includes a first panel, a first plate-shaped insulating member made of plastic foam and having a predetermined thickness, a vacuum insulation member mounted on the insulating member, a second plate-shaped insulating member made of plastic foam, and a second panel. A die extension region is formed around a periphery of the semiconductor die. This average difference in luminance value indicates a degree of difference between fields. Space enclosed by the second engagement portion, the second joint portion, and an inner surface of the one of the frames is exposed toward a side opposite from the installation side.
