Abstract: An image forming system includes a main body including a first control part controlling a power mode of the main body and an engine executing image processing, and an operation apparatus receiving an operation for instructing the engine to execute the image processing. The operation apparatus including a second control part controlling a power mode of the operation apparatus. When the operation apparatus receives an instruction to shift the power mode of the main body or the operation apparatus, the first control part determines whether shifting is possible based on a first program executed by the main body and controls a power supply of the main body according to the determination, and the second control part determines whether shifting is possible based on a second program executed by the operation apparatus and controls a power supply of the operation apparatus according to the determination.

Abstract: An information processing system, an operating device, and computer-readable storage medium. The operating device acquires, from an operation application program installed in the operating device, function information that indicates a function provided by the operation application program, acquires use authority information that is stored in a use-authority information storage device and is related to user identification information on an operating user that operates the operating device, determines whether the operating user has authority to use the function provided by the operation application program by using the use authority information acquired and the function information acquired, and performs the function when the operating user has the authority to use the function.

Abstract: An image processing apparatus includes an operations unit configured to be directly operated by a user; a main unit configured to operate based on a request from the operations unit; a determination unit configured to determine a device that is to use an external storage device of the operations unit, in accordance with one of a function of the main unit that is activated through the operations unit and an application of the operations unit; and a switching unit configured to switch a current connection of the external storage device to a connection between the determined device and the external storage device.

Abstract: An information processing system includes a receiving unit that receives user operation; a setting unit that holds association information in which pieces of necessity information each indicating necessity of a shutdown process indicating a process required for stopping power supply to a corresponding device are associated with a plurality of devices, respectively; a first instruction unit that instructs a target device for which the power supply is to be stopped to perform the shutdown process when the receiving unit receives operation to stop the power supply and the target device requires the shutdown process based on the association information; and a second instruction unit that instructs a power supply control device that controls execution or stop of the power supply to the target device to stop the power supply to the target device when the shutdown process of the target device is completed.

Abstract: An information processing system includes an operating unit that receives an input in response to a user operation and that runs under a first operating system; and a main body that runs under a second operating system and operates in response to the input received by the operating unit. The main body includes a generation unit that generates a command to direct rendering of a screen corresponding to an application being executed, and a command transmission control unit that provides control to transmit the command to the operating unit. The operating unit includes a receiving unit that receives the command from the main body, a screen rendering unit that renders the screen in accordance with the command received by the receiving unit, a display unit that displays the screen rendered by the screen rendering unit, and a reboot unit that reboots the operating unit in asynchronization with the main body.

Abstract: An information processing system includes an operation part that receives an operation performed by a user; and a body part that operates based on a request from the operation part. The operation part includes a power control part that, when receiving a power turning off instruction from the body part, reboots the operation part and causes the operation part to stand by in a power saving state in which some of operations are stopped, and, when receiving a start up notification from the body part, causes the operation part to return from the power saving state.

Abstract: A preview image of image data to be output is generated, in response to a request from an operation device, and can be displayed via the operation device. A first preview image of the image data is generated based on an output setting for outputting the image data. The first preview image is stored in a storage device. The output setting can be changed based on a changing request from the operation device. It is determined, in response to a second preview request from the operation device, after sending the first preview image, whether the first preview image is to be regenerated, based on the changed output setting. The first preview image stored in the storage device can be sent when the first preview image is not to be regenerated, for example, when a second preview image is not to be generated.

Abstract: An information processing system includes an control unit to accept input, an operating unit to execute information processing based on the input accepted by the control unit, and a registration unit to register functional information that indicates the type of function utilized by an application among a plurality of functions included in the operating unit in accordance with an electronic signature linked to the application included in the control unit.

Abstract: An image processing apparatus includes an operations unit configured to be directly operated by a user; a main unit configured to operate based on a request from the operations unit; a determination unit configured to determine a device that is to use an external storage device of the operations unit, in accordance with one of a function of the main unit that is activated through the operations unit and an application of the operations unit; and a switching unit configured to switch a current connection of the external storage device to a connection between the determined device and the external storage device.

Abstract: An image processing system includes a main unit of an image processing apparatus and an operational unit. The operational unit includes a request receiver that receives a request to modify operational unit administrative information, an administrative information modifying unit that modifies the operational unit administrative information in response to the received request to modify, and an administrative information reporting unit that reports modified content of the operational unit administrative information to the main unit of the image processing apparatus. The main unit of the image processing apparatus includes an apparatus information synchronizer that modifies the apparatus administrative information that corresponds to the reported modified content after receiving the modified content of the operational unit administrative information from the operational unit.

Abstract: An information processing system including an operating device and an information processing main body device, the operating device comprising: an application control unit configured to acquire function information of at least one of application program installed in the operation device; and a use-authority determination unit configured to receive the operation from the user and notice to the application control unit, the information processing main body device comprising a authentication unit configured to submit to the use-authority determination unit a user authentication result including a use-authority information, wherein the use-authority determination unit determines whether or not the user is allowed to use the at least one of the application program on the basis of the function information and the use-authority information.
