Abstract

A method for providing a video call service of a terminal according to an embodiment includes establishing a video call session with a second terminal, transmitting a first video that is a photographed video of a first user, from the first terminal to the second terminal, modulating a second video that is a photographed video of a second user and that is received from the second terminal, to a first intensity, and displaying the modulated second video, detecting a predetermined event while the video call session is being maintained, and controlling an intensity of the modulation based on the predetermined event.

First claim

What is claimed is:

1. A method for providing a video call service at a first terminal, the method comprising:
establishing, using a processor, a video call session with a second terminal;
transmitting, using the processor, a first video that is a photographed video of a first user, from the first terminal to the second terminal;
modulating, using the processor, a second video that is a photographed video of a second user and that is received from the second terminal, to a first intensity, and displaying the modulated second video;
detecting, using the processor, a predetermined event while the video call session is being maintained, where the predetermined event comprises a predetermined gesture of the first user detected from the first video; and
controlling, using the processor, an intensity of the modulation based on the predetermined event, wherein controlling the intensity comprises:
determining a different second intensity based on the predetermined gesture; and
displaying the second video modulated to the second intensity.

2. The application according to claim 1 , wherein the method further comprises detecting a second predetermined event, where the second predetermined event is a period of time the video call session is being maintained between the first terminal and the second terminal.

3. The method according to claim 2 , wherein controlling an intensity of the modulation is further based on the second predetermined event, where the controlling an intensity of the modulation further comprises:
when the video call session is maintained for a first period of time, adjusting the intensity of the modulation to a second intensity and displaying the second video modulated to the second intensity; and
when the video call session is maintained for a second period of time after the first period of time, adjusting the intensity of the modulation to a third intensity and displaying the second video modulated to the third intensity,
wherein the second video modulated to the second intensity is clearer than the second video modulated to the first intensity, and the second video modulated to the third intensity is clearer than the second video modulated to the second intensity.

4. The method according to claim 1 , wherein the method further comprises detecting a second predetermined event, where the second predetermined event is an input of the first user of selecting a modulation intensity adjustment icon displayed on a screen of the first terminal.

5. The method according to claim 4 , wherein controlling an intensity of the modulation is further based on the second predetermined event, where the controlling an intensity of the modulation further comprises:
when the input of the first user of selecting a first modulation intensity adjustment icon is received, adjusting the intensity of the modulation to a second intensity that is lower than the first intensity and displaying the second video modulated to the second intensity.

6. The method according to claim 5 , wherein the controlling an intensity of the modulation further comprises:
when an input of the first user of selecting a second modulation intensity adjustment icon is received, adjusting the intensity of the modulation to a third intensity that is higher than the first intensity and displaying the second video modulated to the third intensity.

7. The method according to claim 4 , wherein controlling an intensity of the modulation is further based on the second predetermined event, where the controlling an intensity of the modulation further comprises:
transmitting a request signal for adjusting the intensity of the modulation to the second terminal;
receiving an approval signal for the adjusting of the intensity of the modulation in response to the request signal from the second terminal; and
based on the approval signal, adjusting the intensity of the modulation to a second intensity that is lower than the first intensity and displaying the second video modulated to the second intensity.

8. The method according to claim 1 , wherein the method further comprises detecting a second predetermined event, where the second predetermined event is an input of the first user of selecting a friend request icon displayed on a screen of the first terminal.

9. The method according to claim 8 , wherein controlling an intensity of the modulation is further based on the second predetermined event, where the controlling an intensity of the modulation further comprises:
in response to the selecting the friend request icon, transmitting a friend request signal to the second terminal;
subsequent to the friend request signal, receiving from the second terminal an approval signal for the friend request; and
based on the approval signal, adjusting the intensity of the modulation to a second intensity that is lower than the first intensity and displaying the second video modulated to the second intensity.

10. The method according to claim 1 , wherein the modulating the second video of the second user received from the second terminal to the first intensity and displaying the modulated video comprises:
applying a blur effect or mosaic effect to the second video, or adjusting a color, brightness, contrast or chroma of the second video.

11. The method according to claim 1 , wherein the predetermined event comprises:
at least one of text information, voice information, and emoticon information used during the video call session.

12. A server comprising:
an interface for performing communication with at least one terminal;
a processor; and
a memory for storing commands executable by the processor,
wherein the processor is configured to:
establish a video call session between a first terminal and a second terminal of the at least one terminal,
modulate a video of a first user received from the first terminal and emits the modulated video of the first user to the second terminal,
modulate a video of a second user received from the second terminal and transmit the modulated video of the second user to the first terminal,
detect a predetermined event from at least one of the first terminal and the second terminal, where the predetermined event comprises a predetermined gesture of the first user detected from the first video, and
adjust an intensity of the modulation of the video of the first user and the video of the second user based on the predetermined event, wherein adjusting the intensity comprises:
determining a different second intensity based on the predetermined gesture; and
displaying the second video modulated to the second intensity.

13. A non-transitory computer readable recording medium where commands executable by a processor are stored, the recording medium comprising commands for:
establishing a video call session between a first terminal and a second terminal;
modulating a video of a second user received from the second terminal and displaying the modulated video of the second user;
detecting a predetermined event while the video call session is being maintained, where the predetermined event comprises a predetermined gesture of the first user detected from the first video; and
controlling an intensity of the modulation based on the predetermined event, wherein controlling the intensity comprises:
determining a different second intensity based on the predetermined gesture; and
displaying the second video modulated to the second intensity.

14. A method for providing a video call service at a first terminal, the method comprising:
establishing, using a processor, a video call session with a second terminal;
transmitting, using the processor
