An input/output device that provides a device cooperation service is connected to an input/output service apparatus that provides an input/output service and a computer system that provides a storage service via a network. The input/output device includes a processor configured to execute a program stored in a memory to implement processes of acquiring use restriction information for restricting designation of a condition in a request to the input/output service from the input/output device, and restricting designation of the condition in the request to the input/output service from the input/output device by reflecting the acquired use restriction information on a device cooperation service screen for enabling a user to designate the condition in the request.

A method and apparatus for generating image information. A specific embodiment of the method includes: acquiring a rotation angle and a scaling of a target image relative to a reference image, and acquiring an intrinsic parameter of a video camera collecting the reference image; generating a projective transformation matrix based on the rotation angle, the scaling and the intrinsic parameter; generating a coordinate offset of the each neighborhood pixel of the feature point in the reference image; generating, based on a coordinate of the feature point in the reference image, the coordinate offset of the each neighborhood pixel of the feature point in the reference image and the projective transformation matrix, coordinates of the each neighborhood pixel of the feature point in the reference image; and generating a feature point descriptor of the feature point.

An information providing device is capable of communicating with an image forming device, a data managing device, and a transmission terminal. The information providing device includes a storage unit; a communication unit that transmits a forming instruction to instruct the image forming device to perform image forming, and receives, from the image forming device, storage location information indicating the data managing device that stores data obtained by image forming by the image forming device and indicating a storage location in the data managing device; and a storage location managing unit that generates, in the storage unit, management information in which identification information of the image data is associated with the storage location information. The communication unit receives the data saved in the storage location indicated by the storage location information from the data managing device and transmits the received data to the transmission terminal.

A communication device may receive first specific information from a first terminal device, establish a second wireless connection with a second terminal device after the first specific information has been received from the first terminal device, receive second specific information from the second terminal device after the second wireless connection has been established with the second terminal device, determine whether the first terminal device is identical to the second terminal device by using the first specific information and the second specific information in a case where the second specific information is received from the second terminal device, disconnect the second wireless connection in a case where it is determined that the first terminal device is not identical to the second terminal device, and not disconnect the second wireless connection in a case where it is determined that the first terminal device is identical to the second terminal device.

An image forming system that is convenient for a user even when an image forming apparatus is directly connected to a network in addition to an image control apparatus. The image forming system includes an image control apparatus and an image forming apparatus. The image control apparatus includes a first communication member connected to an external apparatus through a network, a second communication member connected to the image forming apparatus through a predetermined transfer path, and a port controller that controls switching of a predetermined network port of the first communication member. The image forming apparatus includes a third communication member connected to the external apparatus through the network, and a fourth communication member connected to the image control apparatus through the predetermined transfer path. The port controller closes the predetermined network port in a case where both of the third and fourth communication members are valid.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for during a first time period, identifying first digital components for presentation when an electronic document is presented at the client device; generating, using priority indicators assigned to each first digital component, a digital component priority queue that specifies an order of presentation of the first digital components; transmitting, to the client device, the electronic document, the first digital components, and the digital component priority queue; during a second time period that occurs after the first time period, identifying a second digital component for presentation when the electronic document is presented at the client device; and updating the digital component priority queue at the client device, including causing the second digital component to be inserted into the digital component priority queue based on a priority indicator assigned to the second digital component.

A portable terminal has a memory having a program stored thereon and readably by a computer. The program causes the portable terminal to perform deciding an image forming apparatus enabling to execute a first operation as a first designated apparatus which executes the first operation in accordance with predetermined decision criteria, deciding an image forming apparatus designated by a user of the portable terminal as a second designated apparatus which executes a second operation different from the first operation, receiving a designation of designating at least one of the first operation and the second operation, transmitting first instruction information that instructs to execute the first operation to the first designated apparatus when the first operation is designated in the designation, and transmitting second instruction information that instructs to execute the second operation to the second designated apparatus when the second operation is designated in the designation.

In a mobile terminal, a plurality of operating buttons associated with functions performable by an electronic apparatus are provided on an operation screen. A storage section previously stores correspondence information related to the functions performable by the electronic apparatus and indicating correspondence between a relative location between the mobile terminal and the electronic apparatus and a set of functions available depending on the relative location. A first control section allows a display section to display a setting screen for accepting a change in the correspondence information. Based on an operation accepted by an acceptance section on the setting screen, a second control section changes the correspondence information and allows a storage section to store the changed correspondence information. The first control section changes contents of the plurality of operating buttons on the operation screen, using a location of the mobile terminal detected by a detecting section and the correspondence information.
