In addition, in the embodiments of the present disclosure, during the switching from the betting stage to the game stage, a prompt of no more bet (common no-more-bet detection in existing games) may be automatically provided. In addition, in the video streams, if a change in the betting chip in the images of the gaming stage occurs, warning for late bet detection (performing betting after a game card is issued during the gaming stage, which is an irregular betting mode) is automatically issued, and it is determined that the changed chip is the invalid chip. In this way, labor costs are saved, the game efficiency is improved, and the negligence of human monitoring is avoided.

Corresponding to the method embodiments above, the present disclosure further provides apparatus embodiments.

FIG. 7 is a block diagram of a game stage switching apparatus according to an exemplary embodiment of the present disclosure. As shown in FIG. 7, the apparatus includes: a video stream obtaining module 210, configured to obtain a video stream of a game desktop; an object detection module 220, configured to detect a target object for each of image frames comprised in the video stream; and a game stage switching module 230, configured to, in response to detecting a specific target object in at least one image frame in the video stream, switch a game progress stage at a time point corresponding to a first image frame in a plurality of continuous image frames where the specific target object is detected.
