Abstract
The present application provides a method and apparatus for sharing information during a video call. The method includes: receiving an annotation request from a terminal participating in the video call; determining a frame of image that corresponds to the annotation request in the video call as an image to be annotated; receiving from the terminal an annotation message that corresponds to the annotation request; generating an annotated image by annotating at a corresponding position in the image to be annotated based on the annotation message; and transmitting the annotated image. This allows generating the annotated image by a server.

A method for sharing information during a video call, the method comprising steps of:
- receiving an annotation request from a terminal participating in the video call;
- determining a frame of image that corresponds to the annotation request in the video call as an image to be annotated;
- receiving from the terminal an annotation message that corresponds to the annotation request;
- generating an annotated image by annotating at a corresponding position in the image to be annotated based on the annotation message;
- and
- transmitting the annotated image;
- wherein the annotation message comprises a screen resolution of a screen of the terminal and first position information indicative of a position of the annotation on the screen of the terminal, and the step of generating the annotated image comprises:
- calculating a conversion proportion based on the screen resolution of the screen and an image resolution of the image to be annotated;
- converting the first position information to second position information indicative of a position in the image to be annotated according to the conversion proportion;
- and
- generating the annotated image by annotating at the position indicated by the second position information in the image to be annotated.
A method for sharing information during a video call, the method comprising:
- transmitting an annotation request to a server for serving the video call when a first operation performed by a user on an image to be annotated is detected on a terminal participating in the video call;
- extracting, from a sensed annotation made by the user in the image to be annotated, feature information of the annotation, the feature information comprising first position information indicative of a position of the annotation on a screen of the terminal;
- generating an annotation message characterizing the annotation and comprising the first position information and a screen resolution of the screen based on the feature information and the screen resolution;
- and
- transmitting the annotation message to the server to enable the server to make corresponding annotation at a corresponding position in the image to be annotated, the corresponding position being determined according to the first position information and the screen resolution.
An apparatus for sharing information during a video call, the apparatus comprising:
- a receiver configured to receive an annotation request from a terminal participating in the video call, and to receive an annotation message which corresponds to the annotation request;
- an image determiner configured to determine a frame of image that corresponds to the annotation request in the video call as an image to be annotated;
- an image generator configured to generate an annotated image by annotating at a corresponding position in the image to be annotated based on the annotation message;
- a transmitter configured to transmit the annotated image;
- an analyzer configured to analyze the annotation message to obtain a screen resolution of a screen of the terminal and first position information indicative of a position of the annotation on the screen of the terminal;
- a calculator configured to calculate a conversion proportion based on the screen resolution and an image resolution of the image to be annotated;
- a converter configured to convert the first position information to second position information indicative of a position in the image to be annotated according to the conversion proportion;
- and
- an annotator configured to annotate at the position indicated by the second position information in the image to be annotated to generate the annotated image.
