Abstract: An electronic device includes an input screen including: a dial keyboard on which multiple characters are annularly arranged for selection by an operator; an input area into which a character selected from the multiple characters is input at an input position; and a movement key for allowing the operator to move the input position at which the selected character is to be input in the input area to determine the input position. The dial keyboard sequentially displays the multiple characters for selection by the operator on the dial keyboard, according to an operation on the dial keyboard by the operator. The input area displays the selected character at the input position determined in response to an operation on the movement key, in response to a selection of a character from the multiple characters by the operator.

Abstract: An operation display device includes: a display unit that displays an image; a touch panel that is mounted on the display unit; a detecting unit that detects a pressed position on the touch panel and detects a pressing force against the touch panel; and an execution control unit. The execution control unit, if the pressing force is more than a predetermined threshold, executes a first function that is predetermined in accordance with the pressed position and, if the pressing force is equal to or less than the threshold, executes a second function that is predetermined in accordance with the pressed position.

Abstract: Disclosed is an information input device including a touch panel in which a display screen for displaying operations information is integrated with a sensor unit and to which the operations information is input when the display screen is touched with a predetermined unit, the sensor unit having plural sensors, which are capable of measuring a capacitance at a front surface of the display screen, arranged in a staggered manner such that three of the plural sensors adjacent to each other are arranged at positions corresponding to apices of a regular triangle; and a position determination unit that determines a position touched with the predetermined unit on the display screen in accordance with levels of the capacitances detected with the three adjacent sensors in a region of the regular triangle formed by the three adjacent sensors among the plural sensors constituting the sensor unit.

Abstract: A determination unit detects a change of a configuration of an image forming apparatus and determines whether an operation screen needs to be updated based on a content of detected change. When it is determined that an update of the operation screen is needed, a screen-configuration-data acquisition unit acquires screen configuration data corresponding to an operation screen after the update from a storage unit. A generation unit generates operation screen data that is screen configuration data for an updated operation screen based on received screen configuration data and configuration information related to the display unit.

Abstract: A power mode designating unit of a main system outputs an operation mode designating signal to a sub system. Upon shifting from the normal operation mode to the power-saving mode, a control unit of the sub system outputs a power-saving mode shift enable signal indicating that shifting to the power-saving mode is possible to a power control unit of the sub system. When the operation mode designating signal designates the power-saving mode and the power-saving mode shift enable signal indicates that shifting to the power-saving mode is possible, the power control unit supplies a power-saving mode voltage to the control unit.

Abstract: When an operation mode of an image forming apparatus returns from an energy-saving mode to a regular operation mode, a CPU of a main system outputs a power control signal set to High, and determines the necessariness of information display on an LCD of an operation unit control system to output a starting mode selection signal set to High when the result of the determination is positive. A CPU of the operation unit control system detects the state of a power control signal, and detects mode return from the energy-saving mode depending on the result of the above detection. The CPU of the operation unit control system also detects the state of a starting mode selection signal, and determines the necessariness of information display on the LCD depending on the result of the detection to carry out a display process depending on the result of the determination.

Abstract: A reference-data storing unit stores reference data for determining whether to display image data by overwriting display data. A data converting unit converts the image data into display image data. A transparency determining unit determines whether a first pixel value of the display image data obtained through a color conversion by the data converting unit coincides with a second pixel value of the reference data stored in the reference-data storing unit. A data transfer unit that transfers, when it is determined that the first pixel value coincides with the second pixel value, the display image data to a display address space.
