Abstract

A video call processing method includes receiving a substitution request that a video call being performed by a mobile device be performed by the display device, generating, by the display device based on the substitution request, a notification signal corresponding to the substitution request, and transmitting, before a video call screen that includes an image of a counterpart of the video call is output by the display device, the notification signal to a counterpart device, which is a mobile device of the counterpart.

First claim

What is claimed is:

1 . A video call processing method performed by a display device, the video call processing method comprising:
receiving a substitution request that a video call being performed by a mobile device be performed by the display device; generating, by the display device based on the substitution request, a notification signal corresponding to the substitution request, the notification signal comprising at least one of information about a product model of the display device, a product type of the display device, or a display size of the display device; transmitting, before a video call screen that includes an image of a counterpart of the video call is output by the display device, the notification signal to a counterpart device, which is a mobile device of the counterpart; and receiving a selection at the counterpart device to select whether to continue transmitting images of a user of the counterpart device to the display device.

2 . The video call processing method of claim 1 , wherein the notification signal further comprises information indicating that the display device is configured to be viewed by multiple users.

3 . The video call processing method of claim 1 , further comprising performing, based on an offset period of time elapsing after the notification signal is transmitted, the video call by the display device.

4 . The video call processing method of claim 1 , further comprising performing, based on a response for accepting the substitution request being received from the counterpart device, the video call by the display device.

5 . The video call processing method of claim 1 , further comprising activating, based on the substitution request, a camera included in the display device and outputting a video call screen that includes a first image obtained by the camera.

6 . The video call processing method of claim 5 , wherein the outputting of the video call screen comprises outputting, based on a response corresponding to the notification signal being received from the counterpart device, the video call screen that includes the first image and a second image of the counterpart obtained by the counterpart device.

7 . The video call processing method of claim 5 , wherein the outputting of the video call screen comprises outputting, based on the response corresponding to the notification signal not being received from the counterpart device, the video call screen that includes the first image and an alternative image, which is not an image of the counterpart of the video call.

8 . The video call processing method of claim 1 , further comprising:
activating, based on the substitution request, a camera included in the display device and obtaining a first image; and transmitting, to the counterpart device of the video call, first image data corresponding to the first image.

9 . The video call processing method of claim 8 , wherein the transmitting to the counterpart device comprises:
outputting, by the display device, a preview screen that includes the first image; receiving a user input for permitting a video call screen that includes the first image to be output by the counterpart device; and based on the user input being received, transmitting, to the counterpart device, first image data corresponding to the first image.

10 . The video call processing method of claim 8 , wherein the transmitting to the counterpart device comprises:
comparing the first image with an existing image obtained by the mobile device; and based on a result of the comparing, outputting, by the display device, a preview screen that includes the first image.

11 . The video call processing method of claim 10 , wherein the outputting of the preview screen comprises, based on determining that the first image includes an additional imaging area compared to the existing image, outputting, by the display device, a preview screen that includes the first image.

12 . The video call processing method of claim 10 , wherein the outputting of the preview screen comprises, based on determining that the first image includes an additional imaging area compared to the existing image, outputting, before transmitting the first image data from the display device to the counterpart device of the video call, a notification for notifying of the result of the comparing.

13 . The video call processing method of claim 1 , further comprising:
activating, based on the substitution request, a camera included in the display device and obtaining a first image; based on a result of comparing the first image with the existing image obtained by the mobile device, identifying a region of the first image corresponding to the existing image; and controlling image data corresponding to the identified region to be transmitted to the counterpart device.

14 . A display device comprising:
a display; a camera; a communication interface configured to communicate with a mobile device; and a processor configured to execute at least one instruction to:
receive a substitution request that a video call being performed by the mobile device be performed by the display device;
generate, based on the substitution request, a notification signal corresponding to the substitution request, the notification signal comprising at least one of information about a product model of the display device, a product type of the display device, or a display size of the display device;
control the notification signal to be transmitted to a counterpart device of the video call before a video call screen that includes an image of a counterpart of the video call is output on the display; and
receive a selection at the counterpart device to select whether to continue transmitting images of a user of the counterpart device to the display device.

15 . A non-transitory computer-readable storage medium having recorded thereon a program including at least one instruction for performing a video call processing method,
the video call processing method comprising:
receiving a substitution request that a video call being performed by a mobile device be performed by a display device;
generating, by the display device based on the substitution request, a notification signal corresponding to the substitution request, the notification signal comprising at least one of information about a product model of the display device, a product type of the display device, or a display size of the display device;
transmitting, before a video call screen that includes an image of a counterpart of the video call is output by the display device, the notification signal to a counterpart device of the video call; and
receiving a selection at the counterpart device to select whether to continue transmitting images of a user of the counterpart device to the display device.
