The accessory apparatus includes an accessory communicator providing a notification channel (RTS), a first data communication channel (DCL) and a second data communication channel (DCL). The accessory controller transmits, in a transmission request receiving state of receiving a transmission request from an image-capturing apparatus through the notification channel, accessory data to the image-capturing apparatus through the first data communication channel, and receives camera data transmitted through the second data communication channel from the image-capturing apparatus in response to receiving the accessory data. The accessory controller stops, in the transmission request receiving state and during transmission of the accessory data to the image-capturing apparatus, in response to becoming a non-transmission request receiving state, transmitting the accessory data to the image-capturing apparatus.

A server computer sets a priority order of each of contents based on an attribute of each of the contents designated by HTML data and provides the HTML data including the priority order with a client computer. The client computer acquires the contents from the server computer by using streams with priorities depending on the priority order of each of the contents designated by the HTML data provided from the server computer. The client computer controls display using a part of the contents and caches other contents from among the acquired contents.

Information processing device, method, and storage medium for prioritized content acquisition

In the case where a character on an object is read by using a mobile terminal having a camera function, an image suitable to OCR is acquired in a short time. An information processing apparatus including a camera, which acquires a moving image by capturing a character string on an object by the camera, sets, for each frame making up the acquired moving image, a search area for character recognition for each character making up the character string, detects a candidate character from the search area, determines whether an evaluation value indicating likelihood of the detected candidate character is stable, and outputs a frame of the acquired moving image in response to the evaluation value is determined to be stable.

Information processing system and method for prioritized information transfer

An information processing apparatus detects a line segment from an image, determines whether four sides of a plate are detected based on the detected line segment, calculates an aspect ratio of the detected four sides in a case where it is determined that four sides of the plate are detected, and determines whether the aspect ratio satisfies a first condition. In a case where it is determined that four sides of the plate are not detected, the information processing apparatus searches a vicinity of the detected line segment for an object, and determines whether the object satisfies a second condition. The information processing apparatus judges that a recognition target area is included in the image in a case where it is determined that the first condition or the second condition is satisfied.

A web browser of an information processing terminal serving as a user agent (UA) is capable of registering function information of a local service that a local server (printer) provides, which is acquired by search, and function information of a service acquired via a site that a server provides. When receiving Invocation in Web Intents, the web browser displays a list of the registered function information to prompt the user to select a service to be used. If function information that has previously been registered has been found by search, the web browser updates display of the list of the registered function information according to a result of the search.

The accessory apparatus includes an accessory communicator providing a notification channel, a first data communication channel and a second data communication channel. The accessory controller transmits, in response to receiving a transmission request from an image-capturing apparatus through the notification channel, accessory data to the image-capturing apparatus through the first data communication channel and receives camera data transmitted from the image-capturing apparatus through the second data communication channel. The accessory controller has a function of detecting a camera communication error in the camera data and is configured to, when detecting the camera communication error, transmit accessory error information to the image-capturing apparatus and erase the accessory data stored in an accessory data buffer.

In an information processing terminal, a web browser, if instructed by a user to call a function for specific data managed by a client, identifies second function information for adapting the specific data to a type processable by a first function called by using first function information belonging to a category corresponding to the function called by a user's instruction. The web browser issues a request for processing the specific data processed with a second function called by using the identified second function information, with the first function, and receives a processing result of the requested processing.

An image processing apparatus includes an image data obtaining unit configured to obtain first image data which is generated by imaging an object using an imaging unit, an information obtaining unit configured to obtain photographing information of the first image data, and a file generating unit configured to generate a first image file based on the obtained first image data and the obtained photographing information. The file generating unit changes a size of an area of the first image data to be stored in the first image file according to the photographing information.

A virtual device management server manages location information and resource information about a virtual device server as server information. The virtual device management server receives a processing request and printer location information from a printer. Then, the virtual device management server selects a virtual device server for providing a Web service corresponding to the processing request on the basis of server information, the processing request, and location information about the printer to thereby assign the selected virtual device server to the printer.

Web service system, server management apparatus, and web service providing method

An image forming apparatus to communicate with a service provision system via a firewall may include an identification unit, a determination unit, and a communication unit. The identification unit identifies, out of services provided by the service provision system, a service which provides a substitute function corresponding to a function of the image forming apparatus limited by a failure. The determination unit determines, out of a plurality of communication methods to be used for communication with the service provision system via the firewall, a communication method to be used to perform data communication with the service identified by the identification unit. The communication unit performs data communication with the service identified by the identification unit by using the communication method determined by the determination unit.
