In the embodiments of the present disclosure, the game progress stage may include a betting stage, a gaming stage, and a payout stage, and the specific target object may include a game card. The game progress stage may be switched to the gaming stage at the time point corresponding to the first image frame in the plurality of continuous image frames where the specific target object is detected.

In the embodiments, a video stream of a game desktop is obtained; a target object is detected for each image frame in the video stream; and in a case that a specific target object is detected in at least one image frame in the video stream, a game progress stage is switched at a time point corresponding to the first image frame in a plurality of continuous image frames where the specific target object is detected. Through the above process, the game progress stage can automatically be switched based on detecting the specific target object on the video stream, the pace of the game is ensured, hardware costs may be saved, the game time is saved, and the efficiency is improved.

In some optional embodiments, the video stream may include video streams synchronously acquired from the plurality of views of the game desktop. As shown in FIG. 3, the above step 103 may include the following steps.

At step 103-1, the first image frame in the plurality of the continuous image frames where the specific target object is detected is determined in a video stream from one view.
