Abstract: A first conductor is provided on a bottom portion and is electrically connected to a power storage module. A second conductor is provided on the bottom portion side of a cover portion and can be brought into contact with and separated from the first conductor. When the first conductor and the second conductor are brought into contact with each other to close the opening/closing mechanism in a state in which the cover portion is attached to the bottom portion, power is supplied from the power storage module through the power supply path. When the first conductor and the second conductor are separated from each other to open the opening/closing mechanism in a state in which the cover portion is detached from the bottom portion, the supply of power from the power storage module through the power supply path is interrupted.

Abstract: An image processing device according to an embodiment includes a display control unit, a pattern specification unit, and a pattern collating unit. The display control unit generates a composite image that is a surrounding image of a vehicle viewed from a virtual viewpoint, based on images input from in-vehicle cameras, and displays thereof on a display unit. The pattern specification unit specifies an image pattern to be output as the input image among image patterns, for each in-vehicle camera. The pattern collating unit determines whether all image pattern responses from the in-vehicle cameras match with the image pattern. The display control unit displays a certain preparation image on the display unit when the display switching condition to the composite image is satisfied, and displays the composite image thereon instead of the preparation image, when the pattern collating unit determines that all the image pattern responses match with the image pattern.
