An image processing apparatus, that transmits a foreground image including an object and a background image not including the object in order to reproduce a predetermined image generated by combining the foreground image and the background image, acquires the foreground image and the background image, divides the background image, and transmits the acquired foreground image and the divided background images.

Image processing apparatus, transmission method, and storage medium

A control device for a system generates a virtual viewpoint image based on image data obtained by performing imaging from a plurality of directions using a plurality of cameras. The control device includes an obtaining unit configured to obtain game information specifying a type of game which is a target of imaging performed by the plurality of cameras, a storage unit configured to store information for associating the game information obtained by the obtaining unit with setting information of the system, and a setting unit configured to perform a setting process of the system based on the game information obtained by the obtaining unit and the information stored in the storage unit.

Control device, control method, and program

A synchronization signal output apparatus obtains time from a time server to synchronize an internal clock with the time of the time server, obtains an error between the time of the time server and time of the internal clock, and generate and output a synchronization signal. The apparatus sets, based on a magnitude of the error, an operation mode for generating and outputting the synchronization signal, and generates and outputs the synchronization signal at the timing that is based on the operation mode.

Synchronization signal output apparatus, control method, and non-transitory computer-readable storage medium

A control apparatus includes an acquisition unit that acquires selection information for selecting, based on a detection result of a sensor, an image capturing device that captures an image to be displayed and/or stored by a terminal device from among a plurality of image capturing devices, and a control unit that performs control in such a manner that a communication amount related to a captured image from an image capturing device that is unlikely to be selected from among the plurality of image capturing devices based on the acquired selection information becomes less than a communication amount related to a captured image from an image capturing device that is likely to be selected based on the acquired selection information.

Method for controlling an image capturing device that captures an image to be displayed or stored by a terminal device from among a plurality of image capturing devices

An information processing apparatus for a system generates a virtual viewpoint image based on image data obtained by performing imaging from a plurality of directions using a plurality of cameras. The information processing apparatus includes a determination unit configured to determine a generation method for generating a virtual viewpoint image using the image data from among a plurality of generation methods depending on a situation of imaging using the plurality of cameras, and an output unit configured to output data in accordance with a result of the determination performed by the determination unit.

A transmission apparatus configured to transmit, to a receiving apparatus, metadata indicating segment data that the receiving apparatus is allowed to acquire among a plurality of segment data constituting content includes a receiving unit configured to receive, from the receiving apparatus, a request for acquisition of the metadata and an end instruction to end a state in which transmission of the segment data to the receiving apparatus is allowed, and a transmission unit configured to transmit, when the receiving unit receives the end instruction, the metadata containing termination information indicating termination of transmission of the segment data to the receiving apparatus.

Transmission apparatus, receiving apparatus, transmission method, receiving method, and storage medium for transmitting and/or receiving metadata indicating address information for each of a plurality of segments corresponding to divided content

A communication apparatus receives a communication request from a communication partner and determines whether itself functions as a server or a client. If a first parameter for communication for causing the communication partner to function as the client is included in the communication request and the communication apparatus functions as the server, the communication apparatus determines a second parameter for communication for causing the communication apparatus to function as the server based on the first communication parameter. If the communication apparatus offers the communication partner to function as the client in response to the communication request, the communication apparatus determines a third parameter for communication for causing the communication apparatus to function as the client. The communication apparatus transmits data indicating whether the communication apparatus functions as the server or the client, and the second or the third parameter for communication with the communication partner.

Communication apparatus, communication method and program

A network device communicating with an information processing apparatus includes a receiving unit configured to receive an activation request from the information processing apparatus, an activation unit configured to activate the device in response to the activation request, a notification unit configured to provide notification of a first scheduled time indicating a duration time of a state in which the device is not activated, and a responding unit configured to, in response to the activation request received after the notification unit is notified of the first scheduled time, provide notification of a second scheduled time indicating a duration time of the state in which the device is not activated between when the first scheduled time is notified and before a time corresponding to the first scheduled time elapses, and when the activation has been completed, to notify the information processing apparatus of the completed activation.
