Abstract (in Japanese) (See Japanese page) 
(in English) It is important to analyze a service in a table tennis, and a table tennis player confirms a service hitting style and a ball course by an opponent with a video. Since the tendencies of the service and the course are different in a game situation, it is necessary to watch all of the video and to record one. In this study, we propose a method for estimating a score transition in a broadcast table tennis video. A score region in a scoreboard is detected with an image processing, and the score transition is estimated with a brightness change in the detected region. We evaluated the proposed method with five table tennis videos. Experimental result shows that the accuracy of the score transition detection is 90 %.
