Abstract: Image data corresponding to an image captured by a communication terminal device is transmitted from a communication unit of the communication terminal device which is connected to a network to a counter party device which is a counter party of the teleconference. An image display setting indicating whether the captured image is displayed in the counter party device is acquired, according to transmission of the image data. When it is determined that the captured image is in a first state, and the image display setting indicating that the captured image is displayed is acquired, notification information is output from a notification unit of the communication terminal device. When it is determined that the captured image is in a second state, and the image display setting indicating that the captured image is not displayed is acquired, notification information is not output from the notification unit.
