Communication terminal, teleconference system, and recording medium

摘要

Disclosed is a communication terminal transmitting and receiving audio data and at least one of image data obtained by imaging a subject and display data of a shared screen between the communication terminal and one or more other communication terminals via a relay device. The communication terminal includes a detector configured to detect a predetermined event in which transmission of the image data is not required while imaging the subject is continuously executed, and a stopper configured to stop imaging the subject and stop transmitting the image data in response to the detection of the predetermined event.

1. A communication terminal transmitting and receiving audio data and at least one of image data obtained by imaging a subject and display data of a shared screen between the communication terminal and one or more other communication terminals via a relay device, the communication terminal comprising:
circuitry configured to:
detect a predetermined event in which a transmission of the image data is not required while imaging the subject is continuously executed;stop imaging the subject and stop transmitting the image data in response to the detection of the predetermined event;change a transmission management table associated with the transmission of the image data in response to the detection of the predetermined event;stop supplying electric energy to an imaging device, that is configured to output the image data, after having stopped imaging the subject and stopped transmitting the image data to the relay device; andreport to the relay device arrangement information used for a screen display in response to switching to the screen display not displaying the image data, and receiving a report indicating that none of the communication terminal and the one or more other communication terminals utilizes the image data transmitted from the communication terminal, wherein the transmission management table includes information of a terminal identification, a data name of the image data, and a transmission status, the terminal identification indicating a destination communication terminal to which the image data is transmitted, and the predetermined event corresponds to performing the imaging of the subject, and disposing the imaging device within the communication terminal.
