Abstract: A touch operation device includes a touch detection unit that detects a touch operation to a display unit and a touch operation control unit that controls the display unit in accordance with the touch operation that has been detected by the touch detection unit. The touch detection unit acquires touch operation information including information of the number of points that have been simultaneously touch-operated in the display unit and the touch operation control unit determines an operation screen that is displayed when the display unit returns from a sleep state, based on the touch operation information.

Abstract: An image processing device includes a touch sensor and a controller. When an operation in which two icons including a function selection icon and a detailed setting selection icon are simultaneously pressed is received in a reception screen, the controller sequentially switches a setting value of a detailed setting corresponding to the pressed detailed setting selection icon at regular predetermined intervals and changes an image displayed in a preview area to a processed image on which the function has been executed at the switched-to setting value, while the simultaneous pressing operation is continued on the two icons.

Abstract: An image forming apparatus has a standby mode in which the image forming apparatus is ready for executing image processing and a low power consumption mode which consumes lower electric power than the standby mode. The image processing apparatus includes the following four units. The communication unit is connected to a network and communicates with other devices connected to the network. The request frequency monitoring unit acquires information indicating the frequency of requests for image processing received by the communication unit. The start-up schedule-generating unit generates a start-up schedule of the communication unit according to the information acquired by the request frequency monitoring unit. The power control unit switches, when the image processing apparatus is in the low power consumption mode, power supply modes for the communication unit in accordance with the start-up schedule that is generated by the start-up schedule-generating unit.

Abstract: An electric power control unit alternately repeats a first electric power control period and a second electric power control period when a low electric power mode is set by a mode setting unit. When a sleep mode is set by the mode setting unit, a second electric power control is executed.

Abstract: Provided is Electronic apparatus having a function of first power mode and a function of second power mode where power consumption is smaller than first power mode. A plurality of detecting units detects a plurality of trigger operations in second power mode, each of the trigger operations serving as a trigger that causes Electronic apparatus to return from second power mode to first power mode. Mode switching unit causes Electronic apparatus to return from second power mode to first power mode when any one of the plurality of trigger operations is detected by the plurality of detecting units. Power control unit supplies power to the plurality of detecting units in second power mode while performing control of repeating a supply period where power is supplied to the detecting unit and a non-supply period where power is not supplied to it in respect to each of the plurality of detecting units.

Abstract: An image forming apparatus includes: a radio communication portion that transmits and receives data over radio communication to and from a storage medium in which identification information for user identification is stored; a display input portion that displays a function setting screen and receives a function setting; and a control portion that controls operation of the apparatus and forces the display input portion to perform a display changeover depending on an exposure state of the storage medium if the radio communication portion obtains the identification information from the storage medium.
