For example, when the current one view is the left side view of the game desktop, and there is one or more other views, assuming that the other view includes the right side view of the game desktop and/or the top view of the game desktop, the first image frames corresponding to the left side view of the game desktop, e.g., the synchronous images synchronously acquired with image a, are determined in the video streams synchronously acquired from the other view. Correspondingly, the number of the synchronous images may also be one or more.

At step 103-3, in response to detecting the specific target object in at least one image frame of N image frames acquired before the synchronous image, the game progress stage is switched at a time point corresponding to an image frame where the specific target object is detected earliest in the N image frames acquired before the synchronous image.

In the embodiments of the present disclosure, in each round of the game, the specific target object may be detected in the video streams synchronously acquired from the plurality of views. To distinguish each round of the game during switching the game progress stage, and avoid using a time point where the specific target object is detected in the last round of the game as the time point for switching the game progress stage in the present round of the game, the value range of N can be limited. For example, N may be determined according to the average duration of a round of the game, the average duration of each game progress stage, and an image sample frequency, so as to ensure that the N image frames before the synchronous image belong to the same round of the game. N may be greater than or equal to 1, and less than or equal to 30.
