Abstract: The present disclosure discloses a synchronization object determining method, apparatus, and system, where the method includes determining a first distance between the first terminal and the second terminal in a display picture according to location information of the first terminal and location information of the second terminal, and predicting a second distance between the first terminal and the second terminal after specified duration in the display picture, and classifying, by the synchronization device, the second terminal as a synchronization object of the first terminal if the first distance is greater than the second distance. According to the foregoing method, a proper synchronization object is selected for each terminal according to a mobility feature of a terminal. Therefore, on the one hand, an objective of synchronization can be achieved.

Abstract: A screen interaction method and apparatus for an electronic device are disclosed, to determine a target user from a plurality of users and control a picture displayed on a screen of the electronic device based on an action of the target user. The method includes: obtaining, by using a camera, an image including the plurality of users in front of a screen, recognizing respective actions of the plurality of users in the image based on the image including the plurality of users, comparing the actions of the plurality of users with a preset action, determining a user who performs an action matching the preset action as the target user, and controlling a picture displayed on the screen of the electronic device based on the action of the target user.

Abstract: An image processing method is provided, including: obtaining M images acquired by M cameras arranged around a target region; and based on a region in which a target subject is located in the M images, determining one primary camera from the M cameras, and determining N secondary cameras from the M cameras based on a first primary camera, where images acquired by the one primary camera and the N secondary cameras are used to generate a free-viewpoint video, and a region in which the target subject is located in the free-viewpoint video is related to a region in which the target subject is in an image acquired at a primary camera position. The primary camera and the secondary cameras are selected based on the region in which the target subject is located in each of the images acquired by the M cameras.
