The image processing apparatus includes a storing unit configured to store a document in a storage device, a notification unit configured to periodically notify an apparatus of a predetermined destination of information about a document that has been newly stored by the storing unit into the storage device, and a control unit configured to restrict shifting to a power saving mode in which the notification unit cannot make the notification after storage of a document by the storing unit has been completed and until the notification unit notifies at least information about the document.

An image forming apparatus includes a first control circuit, a second control circuit, and a third control circuit. The first control circuit communicates with an information processing device. The second control circuit is configured to communicate with the first control circuit. The third control circuit is configured to communicate with the second control circuit and control a printer. The first control circuit is configured to receive print information from the information processing device during a power-saving mode and control the start of the second control circuit based on the print information. The second control circuit is configured to control a power supply to the third control circuit based on the start by the first control circuit and transmit, to the third control circuit, a warm-up start instruction for the printer based on the print information acquired from the first control circuit after communication with the third control circuit becomes possible.

A control device includes: a wireless communication section that operates while being continuously supplied with power; and a detection section that detects approach of a user. The control device further includes: an authentication processing section that authenticates a user of a terminal in response to reception of a request from the terminal by the wireless communication section when supply of power to a processing section of an information processing apparatus is stopped; and a control section that starts supplying power to the processing section when the approach of the user of the terminal is detected by the detection section after the authentication succeeds.

An information processing apparatus includes a processor configured to shift to an energy saving mode in which predetermined functions are inactivated. The processor includes a detection unit that detects a shutdown operation in the energy saving mode of the information processing apparatus, an operation reception unit that displays, when the shutdown operation is detected, a screen in which a user is prompted to determine whether performance of a shutdown process is to be continued, the operation reception unit receiving an operation through the screen, and a shutdown unit that performs the shutdown process when an operation to continue performance of the shutdown process is received through the screen.

Disclosed is an image forming system including: an image forming apparatus comprising a wireless communication unit; and a terminal device for transmitting a print job to the image forming apparatus, wherein the wireless communication unit executes a wave radio intensity setting process in which the wireless communication unit transmits a received signal intensity request at a predetermined radio wave intensity, receives information from the terminal device, which indicates a received signal intensity at a timing of receiving the received signal intensity request, and sets a radio wave intensity of a radio wave to be transmitted by the wireless communication unit to a set value which is lowered within a range in which the image forming apparatus is communicable with the terminal device in which the received signal intensity indicated in the information is lowest, and the image forming apparatus executes the print job received from the terminal device.

In a case where an image capturing device is in a first state and, in a state where the image capturing device is attached to a communication apparatus, it is judged that a first operation is performed, wireless communication with the communication apparatus is maintained and an operation state of the image capturing device is caused to make a transition to a second state; in a case where, in the first state and in a state where the image capturing device is not attached to the communication apparatus, it is judged that the first operation is performed, the wireless communication with the communication apparatus is not maintained; and in the first state, image capturing by the image capturing device and communication of data by the wireless communication are possible, and in the second state, power consumption is less than that of the first state.

An apparatus determines, when receiving a packet transited via a network in a power saving mode, whether or not the packet is a packet according to a predetermined protocol. If the packet is determined to be the packet according to a predetermined protocol, the apparatus analyzes the data of a succeeding packet described in a data description language, and instructs the apparatus to return from the power saving mode to a normal power mode depending on an analysis result.

To provide a sleep mode control system restricting power consumption while an image forming apparatus (ifma) is in a sleep mode (slm) and allowing a user to deactivate the sleep mode without impairing his/her convenience. The sleep mode control system includes the imf entering the slm to reduce power consumption and a power generator provided below a passage floor on which the imf is mounted. The power generator has a power generation unit, when stepped, provides a private power generation and an electromotive force detection unit detecting an electromotive force generated at the power generation unit successively, generating a pulse signal using the resulting electromotive force, and outputting the resulting pulse signal successively. The ifma has a sleep control part deactivating the slm, while the ifma is being in the slm, based on a signal pattern of the pulse signal outputted from the electromotive force detection unit.

An image forming system that is capable of preventing obstruction of transmission of a packet to an information processing apparatus from a USB device supporting USBNW due to the shift to the sleep mode. The image forming system includes an information processing apparatus, an image forming apparatus with a sleep mode, and a USB device that is connected to the information processing apparatus through the image forming apparatus and is controlled by the information processing apparatus. The image forming apparatus includes a first determination unit that determines whether the USB device supports USBNW, a second determination unit that determines whether a packet received from the information processing apparatus is processed by a module supporting USBNW, and a control unit that prohibits the image forming apparatus from shifting to the sleep mode when the USB device supports USBNW and when the packet is processed by the module supporting USBNW.

A control device is provided and includes: an acquisition unit that acquires the number of persons from a count unit, the count unit counting up the number of persons in an area based on a detection result of a first detection unit, the first detection unit detecting a person who goes in and out through an entrance of the area; and an operation mode control unit that controls an operation mode of a processing device according to the acquired number of persons.
