An image capturing device includes an imaging device and circuitry. The imaging device captures an image. The circuitry defines a point of interest in the image, converts the defined point of interest in accordance with attitude information of the image capturing device, and cuts out a viewable area from the image. The viewable area includes the converted point of interest.

Omnidirectional camera system with improved point of interest selection

A communication management device includes circuitry that: receives captured image data of a captured image obtained by an image capturing device and time-series information representing a date and time associated with predetermined area information, the predetermined area information representing a predetermined area and is transmitted by a communication terminal that displays a predetermined area image of the predetermined area; and transmits, to the communication terminal, converted predetermined area image data obtained through perspective projection conversion based on the received captured image data and the received time-series information.

Communication management device, image communication system, communication management method, and recording medium

A communication management apparatus for communicating with a communication terminal, including circuitry that receives from the communication terminal pieces of designated-position information transmitted, each indicating a corresponding one of a plurality of designated positions in an area where the plurality of image capturing devices are provided, and transmits to the communication terminal identification information of a shareable image capturing device and pieces of predetermined-area information of the shareable image capturing device, the shareable image capturing device being an image capturing device for which distances from any two designated positions among the plurality of designated positions indicated by the pieces of designated-position information are shortest and which is capable of sharing images of the two designated positions, each of the pieces of predetermined-area information of the shareable image capturing device indicating a predetermined area in which a corresponding one of the two designated positions is viewed at the front.

Communication management apparatus, image communication system, communication management method, and recording medium

A communication terminal including circuitry to: receive images captured by a plurality of image capturing devices in a distribution site; accept designation of a point of interest in the distribution site by a user; acquire predetermined-area information indicating a predetermined area including the designated point of interest, the predetermined area being included in an image captured by a specific image capturing device selected based on a position of the point of interest and positions of the image capturing devices; and display a predetermined-area image based on the acquired predetermined-area information, the predetermined-area image being an image of the predetermined area in the image captured by the specific image capturing device.

Communication terminal, image communication system, and method for displaying image

A communication management apparatus includes circuitry to receive from a communication terminal predetermined-position information indicating a predetermined position in an area where a plurality of image capturing devices are provided, and number-of-division information indicating the number of divisions for dividing the area from the predetermined position, and transmit to the communication terminal first predetermined-area information indicating a predetermined area including the predetermined position in an image captured by a first image capturing device and second predetermined-area information indicating a predetermined area including the predetermined position in an image captured by a second image capturing device, the first image capturing device being arranged at a shortest distance from the predetermined position, and the second image capturing device being arranged such that an angle between the second and the first image capturing devices is closest to an angle obtained by dividing the area in accordance with the number of divisions.

An image communication system includes a first communication terminal and a second communication terminal. The first communication terminal acquires an image captured by an image capturing device. The second communication terminal receives the image from the first communication terminal via a network, and displays the image on a screen of a display. The first communication terminal includes first circuitry that, in response to receipt of an operation of switching a view mode related to viewing of the image, transmits the image and first viewable area information to the second communication terminal. The first viewable area information is related to a viewable area of the image to be displayed on the screen. The second communication terminal includes second circuitry that receives the image and the first viewable area information and displays the viewable area of the image on the screen based on the first viewable area information.

Image communication system, image capturing device, communication terminal, and mode switching method

A communication terminal includes circuitry that displays a first image corresponding to a first area of a whole image shared by communication terminals, and stores first terminal information identifying a first one of the communication terminals that causes a second one of the communication terminals to display an image being displayed by the first communication terminal. The circuitry receives second terminal information and viewable area information from a third one of the communication terminals that displays a second image corresponding to a second area of the whole image. The second terminal information identifies the third communication terminal. The viewable area information represents the second area. When the first terminal information and the second terminal information are the same, the circuitry determines whether an operation state of the first image is an operating state, and if so, displays the second image after the operation state shifts to a standby state.

Communication terminal, image communication system, display method, and non-transitory recording medium

An imaging device incorporated in an omnidirectional video capturing system including an imager, a memory, and a transmitter. The imager includes imaging lenses to capture images from a plurality of directions. The memory stores projective transformation data. The projective transformation data includes photographing direction data representing the plurality of directions and projection data representing image heights of the images associated with angles at which light rays enter the imaging lens. The transmitter reads the projective transformation data stored in the memory, and transmits frame data of the images and the projective transformation information to an image processing device of the omnidirectional video capturing system.

Imaging device and method

A device is provided that includes a recording medium with embedded communication functionality, a communication controller, a communication status verifier, a communication period calculator, and a verification interval setter. The recording medium stores data. The communication controller transmits the data to an external system via the recording medium. The communication status verifier obtains the communication status of the recording medium at a predetermined interval. The communication period calculator estimates a communication period required by the communication controller when transmitting the data to the external system. The verification interval setter relatively increases the frequency of the communication status verification, which is performed by the communication status verifier, from a predetermined time before or a predetermined time after the end of the estimated communication period until the obtained communication status indicates completion of the data transmission.

Communication system for digital camera and mobile device with variable verification

A software communication unit executes a plurality of application communications executed in parallel in a network according to a TCP/IP control by a software. A hardware communication unit executes the application communications according to a TCP/IP control by a TCP/IP offload engine (TOE). A communication allocating unit executes an allocation processing for allocating a hardware communication by the hardware communication unit and a software communication by the software communication unit based on reference information on each of the application communications, for application communications that are simultaneously executed.
