An equipment control system includes an equipment control device that controls equipment provided in an office room, and an external control device that is provided outside the office room and controls the equipment provided in the office room via the equipment control device, wherein when a predetermined condition is satisfied, a control device that controls the equipment is switched from one of the equipment control device and the external control device to the other.

An image forming system includes an image forming apparatus and a communication terminal. The image forming apparatus communicates with the communication terminal and includes an operation panel that displays a first display screen and accepts an operation of inputting information, and a hardware processor. The communication terminal communicates with the image forming apparatus, displays a second display screen, and accepts input of information and includes a central processing unit (CPU) that notifies the input of the information to the image forming apparatus. The communication terminal transmits the information input in the input device to the image forming apparatus, and the hardware processor determines whether the status of the operation panel is a status that accepts the operation, and upon the status of the operation panel being the status that accepts the operation, switches the first display screen to a screen that accepts the operation.

Provided is an image forming system that simply and securely protects printed matter that is not so important, but that the user does not wish others to view. An external apparatus receives a simple-security setting for image data for which there is a printing instruction, includes the simple-security setting in the printing instruction, and transmits the printing instruction to an image forming apparatus. The image forming apparatus, when a simple-security setting is included, adds a mark image to the image data for which there is a printing instruction, and prints the image data. A projector, by an imaging unit, captures an image of the discharge tray, and when a mark image is detected, generates a projection image on which a security image is arranged, and projects the projection image toward the discharge tray.

A communication control method which prevents control over a USB device from being hampered and reducing power consumption at the same time. When the USB device and a control apparatus, which controls the USB device, are connected to the printing apparatus, and a communication via the printing apparatus is being carried out, the printing apparatus and the USB device are not shifted into a power saving mode in which energization of the printing apparatus and the USB device is limited. When the USB device and the control apparatus are connected to the printing apparatus, and a communication via the printing apparatus is not being carried out, the printing apparatus and the USB device are shifted into the power saving mode.

A terminal device performs operations includes: a file information receiving process to receive M pieces of file information for identifying M image files from a printer storing M image files; a specific signal receiving process to receive a specific signal from the printer; a determination process to determine whether an inter-device distance is equal to or less than a predetermined distance by using a received radio field intensity of the specific signal; a selection process to select N pieces of file information, which is a part of the M pieces of file information when it is determined in the determination process that the inter-device distance is equal to or less than the predetermined distance; and a print instruction transmission process to not transmit the print instruction to the printer when it is determined that the inter-device distance is not equal to or less than the predetermined distance.

Methods and devices for providing notifications for camera resource availability may include receiving requests from a plurality of applications for control of a camera resource. The methods and devices may include providing control of the camera resource to a selected application from the plurality of applications when another application does not have control of the camera resource. The methods and devices may include sending a control notification to one or more applications, including at least one of the plurality of applications indicating that the selected application has control of the camera resource. The methods and devices may include sending an availability notification to the one or more applications, including the at least one of the plurality of applications indicating that the selected application has released the control of the camera resource.

An electronic device includes: a communication unit that performs communication with an external device; and a control unit that issues a command to the external device via the communication unit, on the basis of at least one of capacity of the external device, and capacity of the electronic device.

A communication system including an image processing apparatus configured to receive N-th operation definition information from a server, when the N-th operation definition information includes an option selecting instruction, set a user interface to be allowed to accept an option selecting operation, and transmit to the server, next-operation request information being for requesting the server to transmit (N+1)th operation definition information, when the N-th operation definition information includes an operation instruction, control an image processor to perform an operation as instructed by the operation instruction, set an apparatus-side network interface to be allowed to receive from a mobile terminal device, shortcut information indicating that a coordinated operation is started from an M-th unit operation of the plurality of unit operations, and when receiving the shortcut information from the mobile terminal device via the apparatus-side network interface, transmit the shortcut information to the server via the apparatus-side network interface.

Disclosed is a job execution device, including: an operation panel; a communicator for communicating with another job execution device; and a hardware processor that: displays its own operation window and the operation window of the another job execution device on the operation panel; receives a setting of a distribution process for distributing a process for executing the job relating to a first function between the job execution device and the another job execution device by a predetermined operation, when a selection button of the first function exists in both of its own operation window and the operation window of the another job execution device; and instructs the job executor of the job execution device and the another job execution device to carry out the distribution process, when an entry of the job relating to the first job is received in a situation in which the distribution process is set.
