  • Patent number: 11042342
    Abstract: 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.

  • Patent number: 10944798
    Abstract: 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.

  • Patent number: 10944619
    Abstract: 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.
