When displaying in the energy saving mode, an operation screen having operation buttons related to functions that can be used in the energy saving mode, control is carried out so that the operation buttons 64 - 66 related to the functions that can be used in the energy saving mode are displayed in a form that is different from that of the operation buttons 61 - 63 related to the functions that can be used only during the normal mode. For example, the operation buttons that can only be used in the normal mode are not displayed in the operation screen of the energy saving mode, or else, the operation buttons 61 - 63 that can only be used in the normal mode and the operation buttons 64 - 66 that can be used in the energy saving mode are displayed in different colors. |
