A signal processing device includes a data writing unit, a channel number converting unit, and a plurality of serial data transferring unit. The data writing unit is configured to write data of m channels into a memory. The channel number converting unit is configured to output the data read from the memory as data of n channels, where m is larger than n. The plurality of serial data transferring unit is configured to transfer the data of the n channels to a processing device in a subsequent stage.

An image reading apparatus includes an imaging device, a first communication device capable of communicating at a first communication speed according to a first communication protocol, a second communication device capable of communicating at a second communication speed lower than the first communication speed according to a second communication protocol different from the first communication protocol, a first processor to separately transmit a first image acquired by imaging a first surface of a medium by the imaging device, and a second image acquired by imaging a second surface of the medium by the imaging device, via the first communication device, and a second processor to transmit a combined image acquired by combining the first image and the second image via the second communication device.

An information processing system includes an information input device and an information processing apparatus. The information input device acquires audio information. The information processing apparatus is connected to the information input device via a network. The information processing apparatus includes circuitry that, based on a determination that the audio information acquired by the information input device is incomplete, complements the audio information, converts the audio information into process information, and transmits the process information to a target apparatus.

A communication device including: a transmission file setter which sets an upper limit value of a capacity of a file transmittable by e-mail; a transmission page setter which sets a page count of a transmission file; a communicator which divides, when the transmission file including multiple pages exceeds the upper limit value, the transmission file into multiple divided transmission files, and transmits the divided transmission files; a transmission setter which receives a combining configuration file for combining the divided transmission files, and the setting of a combining tool; and a controller which controls the transmission file setter, the transmission page setter, and the communicator. When the communicator transmits the plurality of divided transmission files, the controller causes the communicator to also transmit the combining configuration file and the combining tool for creating a file of the page count, in accordance with the setting of the transmission setter.

A user personal computer (PC) serves as a transmission device for transmitting data to a terminal device. The user PC includes a user PC communicator, an inputter configured to receive an input of a selection instruction for selecting data to be transmitted by the user PC communicator and an input of a transmission instruction for transmitting data, and a transmission controller configured to control the user PC communicator to transmit data selected by an input received by the inputter and a notification regarding the selected data. The data and the notification regarding the data are transmitted through different communication paths to the terminal device.

When an image forming apparatus acquires notification destination information from a document processing flow execution system, and is instructed to change information, the image forming apparatus requests that a master system, indicated by the notification destination information, change the information. The master system changes the information held by the master system itself as requested by the image forming apparatus. When the image forming apparatus is notified about the successful change of information from the master system, the image forming apparatus notifies a slave system, indicated by the notification destination information, about the change of information. When the slave system is notified about the change of information by the image forming apparatus, the slave system changes the information held by the slave system itself to the information acquired from the master system.

An image processing apparatus includes: a gradation correction section that performs output gradation correction with respect to input multi-value image data; a conversion section that converts the multi-value image data, which is acquired after the output gradation correction is performed by the gradation correction section, into binary image data; a storage section that stores the multi-value image data or the binary image data; and a control section that performs control such that the multi-value image data, which is acquired before the output gradation correction is performed, is stored in the storage section in a case where content of the input image data is content which requires the output gradation correction, and such that the binary image data is stored in the storage section in a case where the content of the input image data is content which does not require the output gradation correction.

An information processing apparatus includes a management unit that deletes from a first region a fax document that has been successfully transferred to a predetermined transmission destination and moves from the first region to a second region a fax document that has been unsuccessfully transferred to a transmission destination. A user is not permitted to perform an operation on the fax document stored in the first region and the user is permitted to perform an operation on the fax document stored in the second region.

An information processing apparatus includes a processor programmed to execute a process. The process includes obtaining, from apparatus management information associating identifiers of other information processing apparatuses with resources of services being used by the other information processing apparatuses, one or more of the identifiers of the other information processing apparatuses associated with resources of a service available to a user, displaying the obtained one or more of the identifiers of the other information processing apparatuses on a display device as remote connection destinations in association with the resources of the service available to the user such that the resources of the service available to the user are selectable, and performing remote sharing with one or more of the other information processing apparatuses whose identifiers are associated with a resource selected on the display device from the resources of the service available to the user.

An information processing system includes an information input device and an information processing apparatus. The information input device acquires audio information. The information processing apparatus is connected to the information input device via a network. The information processing apparatus includes circuitry that, based on a determination that the audio information acquired by the information input device is incomplete, complements the audio information, converts the audio information into process information, and transmits the process information to a target apparatus.
