PROBLEM TO BE SOLVED: To increase the entertainingness of KARAOKE by comparing dancer's posturing data generated on the basis of the detected posturing of a user with posturing data wherein the posturing of a model dancer and scoring the dance performance of a user. SOLUTION: Optical motion capture technologies are employed so as to generate dancer posturing data in a KARAOKE hall. A motion detection part 40 samples video signals from two CCD cameras 42 at intervals of playing elapsed time and processes their images to detect the coordinate position of each mirror 41. The coordinate positions are converted to the same coordinate system with posturing data to generate dancer posturing data, which are outputted sequentially according to the posturing of the dancer. A scoring part 50 compares the dancer posturing data with posturing data sequentially in playing time series to obtain differences between the vectors of respective human body positions of the two data sequentially in playing time-series order, specific points based upon the differences are added, and the final totalization result is converted to scores based upon 100 as the top scores, thereby outputting score information. |
