Abstract: Provided is an application stored in a computer-readable storage medium to perform a method of providing a video call service using icon information corresponding to a facial expression of a user.

Abstract: Provided are a terminal for providing a video call service by generating evaluation information corresponding to a gesture of a user of a video call service and a server for providing a video call service based on a reputation quotient of a user based on the evaluation information received from the terminal.

Abstract: Provided is an application stored in a computer-readable storage medium to perform a method of providing a video call service, the method including, in a first terminal, establishing a video call session between the first terminal and a second terminal; modulating and displaying an area of an image of a second user, except for an exposure area, the image of the second user being displayed in the first terminal; detecting a predetermined event during the video call session; and controlling a size of the exposure area based on the predetermined event.

Abstract: There is provided an application stored in a computer-readable storage medium and enabling a first terminal to perform a method of providing a video call service, the method includes: establishing a video call session between the first terminal and a second terminal; displaying an exposure control area for controlling an exposure area of an image of a first user displayed on the second terminal; receiving an input of the first user for controlling the exposure control area; and transmitting a signal for controlling the exposure area to the second terminal in response to the input of the first user.

Abstract: There is provided an application stored in a computer-readable storage medium for a first terminal to perform a method of providing a video call service, the method including: establishing a video call session between the first terminal of a first user and a second terminal of a second user; preparing facial expression information of the second user accumulated in at least one video call session executed by the second terminal before the video call session; determining emotion information corresponding to the facial expression information of the second user based on the facial expression information of the second user; and providing the determined emotion information through an execution screen of the first terminal.

Abstract: There is provided an application stored in a computer-readable storage medium for a first terminal to perform a method of providing a video call service, the method including: receiving a first video stream of a first user of the first terminal when the application that provides the video call service is executed; extracting facial feature points of the first user from the first video stream; predicting whether the first user is a bad user by applying distribution information of the facial feature points of the first user to a learning model for bad user identification based on facial feature points of a plurality of users; and controlling display of a component on an execution screen of the application based on a result of the predicting.

Abstract: A server includes a session management device establishing a video call session between a first electronic apparatus of a first user and a second electronic apparatus of a second user, a communication device receiving match satisfaction calculated from the first electronic apparatus through the video call session, an image analysis device obtaining first feature point distribution information from a face image of the first user and obtaining second feature point distribution information from a face image of the second user, a processor training a machine learning model by using the first feature point distribution information, the second feature point distribution information, and the match satisfaction and estimating the match satisfaction of the first user for each of standby users by using the trained machine learning model when a video call connection between the first electronic apparatus and the second electronic apparatus is terminated, and a user management device selecting a third user, who becomes a

Abstract: An electronic apparatus making a video call includes a processor dividing an image of a user of the electronic apparatus into a plurality of areas and editing an area, which is not selected from the user, from among the plurality of areas to generate the edited image, an input device receiving a selection input to select at least one area among the plurality of areas from the user, and a communication device transmitting the edited image to an electronic apparatus of a video call counterpart.

Abstract: Disclosed herein is an apparatus for remote sensing using a drone. An apparatus for remote sensing using a drone includes: a drone station which communicates with a server through a satellite and includes a containment portion at an upper portion and a post portion at a lower portion; and a drone which is contained in a containment portion of the drone station and communicates with the drone station, and further includes: a solar panel which is installed at the drone station and converts solar energy into electric energy; an capacitor which is installed at the drone station and stores electric energy generated by the solar panel; and a charging container access deck which is installed at the containment portion and charges the drone.

Abstract: An evaluator credibility based content credibility evaluation apparatus and method thereof are disclosed. A content credibility e valuation method that includes obtaining evaluation information of a content evaluator about content; obtaining credibility of the content evaluator from a user information database; and calculating content credibility based on the credibility of the content evaluator and the evaluation information, allows consideration of the content evaluator's credibility in content credibility evaluation and enhancement of online search engine performance.
