Information providing device, image forming device, and transmission system for providing image data to a transmission terminal that performs video communication

A first transmission terminal comprising:

• one or more communication interfaces capable of communicating with an information providing device;
• and
• circuitry configured to
• transmit first captured image data captured by a camera to a second transmission terminal which is a participant of a video conference,
• display, on a display screen, second captured image data transmitted from the second transmission terminal,
• receive, during transmission of the first captured image data, image data that is obtained by the information providing device and that is transmitted from the information providing device when the information providing device receives an instruction to start transmission of the image data obtained by the information providing device, and
• automatically display, during transmission of the first captured image data, the received image data obtained by the information providing device together with the second captured image data on the display screen while transmitting the received image data to the second transmission terminal.

A method implemented by a first transmission terminal that includes one or more communication interfaces capable of communicating with an information providing device, the method comprising:

• transmitting first captured image data captured by a camera to a second transmission terminal which is a participant of a video conference;
• displaying, on a display screen, second captured image data transmitted from the second transmission terminal;
• receiving, during transmission of the first captured image data, image data that is obtained by the information providing device and that is transmitted from the information providing device when the information providing device receives an instruction to start transmission of the image data obtained by the information providing device;
• and
• automatically displaying, during transmission of the first captured image data, the received image data obtained by the information providing device together with the second captured image data on the display screen while transmitting the received image data to the second transmission terminal.
