The communication unit 13 is a communication module that realizes communication connection to a communication network such as the Internet. The communication unit 13 uses a network card, a wireless communication device, or a carrier communication module.

The display unit 14 uses a liquid crystal panel, an organic EL (Electro Luminescence) display, or the like. The display unit 14 can display an image by the processing in the image processing unit 11 in response to an instruction from the control unit 10.

The operation unit 15 includes a user interface such as a keyboard, a mouse, and the like. A physical button provided in a casing may be used, and a software button or the like displayed on the display unit 14 may be used. The operation unit 15 notifies the control unit 10 of information on an operation by a user.

The reading unit 16 can read an image processing program 2P and a super-resolution image 2M stored in a recording medium 2 using an optical disk or the like, for example, by using a disk drive. The image processing program 1P and the super-resolution image 1M stored in the storage unit 12 can be duplicates obtained by the control unit 10 by duplicating the image processing program 2P and the super-resolution image 2M read from the recording medium 2 by the reading unit 16 to the storage unit 12.
