An image communication system includes a first communication terminal including first circuitry and a second communication terminal including second circuitry. The first circuitry of the first communication terminal transmits, to the second communication terminal, first image data representing a first image and second image data representing a second image. The first circuitry of the first communication terminal transmits, to the second communication terminal, position information indicating a predetermined position on the first image. The second circuitry of the second communication terminal combines, based on the position information, the second image with the first image at the predetermined position on the first image to generate a combined image. The second circuitry of the second communication terminal displays, on a display, the combined image.

Communication terminal, image communication system, and display control method

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

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

A communication terminal includes circuitry. The circuitry receives data of a whole image, data of a material image, and superimposition position information indicating a position where the material image is to be superimposed on the whole image, the data of the whole image, the data of the material image, and the superimposition position information being transmitted from another communication terminal. The circuitry superimposes the material image on the whole image at the position indicated by the superimposition position information. The circuitry causes a display to display a predetermined-area image, which is an image of a predetermined area of the whole image. When at least a part of the material image being superimposed is not displayed in the predetermined-area image, the circuitry changes the position where the material image is superimposed such that the material image is displayed at a predetermined position in the predetermined-area image.

The first circuitry of the first communication terminal is configured to transmit a plurality of pieces of image data and layer display order information indicating a layer display order in which a plurality of images represented by the plurality of pieces of image data are to be displayed. The second circuitry of the second communication terminal is configured to display the plurality of images represented by the plurality of pieces of image data transmitted from the first communication terminal in the layer display order based on the layer display order information transmitted from the first communication terminal.
