A first communication apparatus may repeat a broadcast transmission of a trigger signal via a second interface, which is a signal to be used by a second communication apparatus as a trigger for sending a wireless connection request to the first communication apparatus. The wireless connection request may be for forming a first wireless network to which both the first communication apparatus and the second communication apparatus belong. The first wireless network may be a network for performing a wireless communication via a first interface. The first communication apparatus may receive the wireless connection request via the first interface from the second communication apparatus which has received the trigger signal, and establish a first wireless connection via the first interface with the second communication apparatus so as to form the first wireless network.

A digital photo frame system is described herein. The system comprises a master digital photo frame configured to display a master media and a plurality of slave digital photo frames configured to display a plurality of slave media. The master digital photo frame is configured to provide power to the plurality of slave digital photo frames, and receive a media package from a storage location. The media package comprises the master media and the plurality of slave media. The master digital photo frame is configured to send each of the plurality of slave media to a respective slave photo frame.

A communication apparatus may perform: communicating a wireless setting value with a printer via a first wireless communication interface, establishing the wireless connection with the printer via a second wireless communication interface using the wireless setting value; sending first image data representing a first image of a print target to the printer via the second wireless communication interface using the wireless connection; determining, after the first image data is sent to the printer, whether an apparatus-side disconnection condition is satisfied; disconnecting the wireless connection when it is determined that the apparatus-side disconnection condition is satisfied; and sending, when it is determined that the apparatus-side disconnection condition is not satisfied, second image data representing a second image of a print target to the printer via the second wireless communication interface using the wireless connection.

A team photographing method can be applied to terminals. The terminals can include a main terminal and at least one member terminal. The method includes: forming a team including the main terminal and the at least one member terminal based on a team photographing instruction initiated by the main terminal; based on a target object to be photographed determined by the main terminal, determining the target object to be photographed of the at least one member terminal; and controlling, by the main terminal, the main terminal and the at least one member terminal to photograph the target object to be photographed cooperatively.

Provided is an image processing apparatus to form an image on a sheet of paper, including a main body and a submodule detachably disposed on the main body. The main body includes an asynchronous serial bus and a master control unit. The submodule includes a slave control unit. An interactive asynchronous serial communication is performed between the master control unit and slave control unit. The master control unit includes a detection timing changing unit. The detection timing changing unit changes a scheduled timing to detect a second signal. The slave control unit includes a transmission signal changing unit. The transmission signal changing unit changes a state of the second signal from a first state detectable by the master control unit at a first timing to a second state detectable by the master control unit at a second timing.

An image processing apparatus serving as a master device and a plurality of local image processing apparatus serving as local devices are connected to one another via a network, and each of the devices includes an authentication information storage unit and an authentication unit. The master device stores, as master authentication information, authentication information necessary for an authentication on each of users who are able to use each of the devices, for each of the devices, and allows editing of the master authentication information. When the authentication information on the local device in the master authentication information is edited, the edited authentication information is transmitted to the local device, and the authentication information stored in local device is updated. When a user login operation is performed on the local device, an authentication is performed by using the authentication information in the local device.

Synchronization of simultaneously captured media in a multi-camera system is performed using a consistent file structure within the cameras. A primary camera receives a bitmap describing the file and folder utilization of each of one or more secondary cameras. The primary camera selects a folder number and file position number that is commonly available across all cameras. The primary camera directs the secondary cameras to store subsequently simultaneously captured media content at the selected file number and folder position number. During post-processing, simultaneously-captured content is accessed based on common folder numbers and file position numbers. A post-processing system compares a timestamp associated with each content file in a group with matching folder numbers and file position numbers to identify false positive groupings.

In various examples, a master press and a slave press may be synchronized. A signal associated with the master press printing a first frame on a first web may be received. A point in time may be determined at which the slave press should begin printing, on a second web, a second frame corresponding to the first frame. The determining may be based on the signal associated with the master press and a first distance between the slave press and a downstream location at which the first and second webs converge. The slave press may be operated to begin printing the second frame at the point in time.

An image capturing apparatus receives an operation by a user and communicates with an external apparatus. The apparatus performs control to transmit a plurality of captured images in a predetermined order to a communication apparatus via the communication unit. During transmission of the plurality of the images in the predetermined order, in accordance with an instruction to change a transmission order of a first image having been received, the image capturing apparatus performs control to prioritize transmission of the first image and further performs control such that transmission of an image linked with the first image to the communication apparatus is prioritized by another image capturing apparatus capable of communicating via the communication unit.

A communication apparatus may perform: communicating a wireless setting value with a printer via a first wireless communication interface, establishing the wireless connection with the printer via a second wireless communication interface using the wireless setting value; sending first image data representing a first image of a print target to the printer via the second wireless communication interface using the wireless connection; determining, after the first image data is sent to the printer, whether an apparatus-side disconnection condition is satisfied; disconnecting the wireless connection when it is determined that the apparatus-side disconnection condition is satisfied; and sending, when it is determined that the apparatus-side disconnection condition is not satisfied, second image data representing a second image of a print target to the printer via the second wireless communication interface using the wireless connection.
