Abstract: A video reproduction apparatus determines a position of a joint of a performer based on a sensing result by a sensor. The video reproduction apparatus calculates an angle formed by a joint used for scoring an element of an athletic event by using calculation information regarding a calculation formula for calculating the angle and the determined position of the joint of the performer. The video reproduction apparatus displays a performance image of the performer acquired from a camera and a scoring image having the angle displayed on a 3D model image of the performer which is generated according to the sensing result so as to be compared with each other.
